Description
本發明係關於用以產生具有所期望之特性的微細氣泡之水系組成物及微細氣泡產生裝置。更具體而言，本發明係關於用以產生具有適於用於洗淨之特性的微細氣泡之水系組成物，及不需大型泵等的設備而尺寸小且成本低的微細氣泡產生裝置。再者，本發明亦關於使用該水系組成物及/或微細氣泡產生裝置所產生之微細氣泡所致之洗淨方法。The present invention relates to an aqueous composition and a fine bubble generating device for generating fine bubbles with desired characteristics. More specifically, the present invention relates to an aqueous composition for generating fine bubbles having characteristics suitable for washing, and a small size and low cost fine bubble generating device that does not require equipment such as large pumps. Furthermore, the present invention also relates to a cleaning method using the water-based composition and/or the fine bubbles generated by the fine bubble generating device.
在照護設施、醫院等所利用的租賃衣類或寢具類、在保全公司等所利用的制服類，係基於衛生管理上的理由而要求清潔。因此，頻繁地進行洗滌，而有因清洗排水導致之對環境的影響之疑慮。進而，因如此頻繁的洗滌所造成之洗淨對象物、即衣類等的損傷亦無法避免(有關微奈米氣泡水之洗淨的基本性能：共立女子短期大學生活科學科紀要)。Rental clothing or bedding used in nursing facilities, hospitals, etc., and uniforms used in security companies, etc., are required to be cleaned for hygienic management reasons. Therefore, washing is performed frequently, and there are doubts about the impact on the environment due to washing drainage. Furthermore, damage to the cleaning objects, clothing, etc. caused by such frequent washing is also unavoidable (the basic performance of the cleaning of micro-nano bubble water: Summary of Life Science Department of Kyoritsu Women's Junior College).
此外，於照護設施、醫院等中，雖為了保持住院患者、高齡者的身體之清潔，而進行沐浴、擦淨，但在大多數的情況下會對皮膚造成負擔而較不佳。尤其，對於患有皮膚疾病的患者或高齡者而言，若是皮膚不乾淨則症狀會惡化而必須清潔，但，必須要避免對皮膚的刺激。因此，要求有對皮膚造成物理性的刺激少的洗淨方法。In addition, in nursing care facilities, hospitals, etc., although bathing and scrubbing are performed to keep the bodies of inpatients and elderly people clean, in most cases it will burden the skin, which is not good. In particular, for patients with skin diseases or elderly people, if the skin is not clean, the symptoms will worsen and it is necessary to clean it, but it is necessary to avoid skin irritation. Therefore, a cleansing method that causes less physical irritation to the skin is required.
另外，近年來，被稱為微細氣泡之微小的泡，在水質淨化等的環境領域、洗淨或燃燒改善等的產業領域、殺菌或洗淨等的食品領域、洗澡或健康增進等的日常領域之各領域中被活用。此外，利用有如此之微細氣泡的洗淨，係作為對洗淨對象物或環境之負擔少的技術而備受期待。例如，作為使用有微細氣泡的洗淨方法，於日本特開2005-118462號公報中，揭示有於清洗的洗滌步驟中使用微泡的清洗裝置。此外，於日本特開2007-83142號公報中，針對將包含界面活性劑之洗淨液與微泡組合而成的洗淨方法作揭示，於日本特開2016-132712號公報中，記載有藉由添加微細氣泡與消毒劑及界面活性劑，而提昇隱形眼鏡的洗淨效果。In addition, in recent years, tiny bubbles called microbubbles have been used in environmental fields such as water purification, industrial fields such as cleaning or combustion improvement, food fields such as sterilization or cleaning, and daily fields such as bathing or health promotion. It is flexibly used in various fields. In addition, cleaning with such fine bubbles is expected as a technology that has less burden on the cleaning object or the environment. For example, as a cleaning method using fine bubbles, Japanese Patent Application Laid-Open No. 2005-118462 discloses a cleaning device that uses micro bubbles in the washing step of cleaning. In addition, Japanese Patent Laid-Open No. 2007-83142 discloses a method of cleaning by combining a cleaning solution containing a surfactant and microbubbles. Japanese Patent Laid-Open No. 2016-132712 describes borrowing By adding fine bubbles, disinfectants and surfactants, the cleaning effect of contact lenses is improved.
微細氣泡(fine bubble)係指直徑100μm以下的氣泡，其中，將直徑1～100μm之可目視的白濁之氣泡稱為微泡(micro bubble)，將直徑1μm以下之無法目視的無色透明者稱為超微細氣泡(ultrafine bubble，微細氣泡學會聯合HP：http://www.fb-union.org/index.html)。A fine bubble refers to a bubble with a diameter of 100μm or less. Among them, a bubble with a diameter of 1 to 100μm that can be seen is called a micro bubble, and a colorless and transparent bubble with a diameter of 1μm or less is called a colorless and transparent one that cannot be seen. Ultrafine bubble (ultrafine bubble, microbubble society joint HP: http://www.fb-union.org/index.html).
微細氣泡由於非常微小，因此相較於通常的氣泡，具有各種特徵性的性質。尤其，相較於通常的氣泡，在相同的容積下比表面積較大，因此，在氣液界面之作用面的物理性吸附力非常大。於任何應用領域中，氣泡之此吸附作用都是重要的，因而，為了盡可能地增大相同體積中之氣泡的表面積，較佳為盡可能地縮小氣泡徑而盡可能地提高氣泡的密度。Since the fine bubbles are very small, they have various characteristic properties compared to ordinary bubbles. In particular, compared to ordinary bubbles, the specific surface area is larger under the same volume, so the physical adsorption force on the acting surface of the gas-liquid interface is very large. In any application field, the adsorption of bubbles is important. Therefore, in order to maximize the surface area of the bubbles in the same volume, it is better to reduce the bubble diameter as much as possible and increase the density of the bubbles as much as possible.
作為現在已知的微細氣泡產生裝置，例如，於日本特開2006-289183號公報中記載的方法及裝置，係藉由將包含微泡的液體供給至儲存槽，並對於此液體施加超音波振動，將液體中的微泡壓壞，而於液體中產生奈米氣泡。又，於日本特開2012-250138號公報中記載的裝置，係藉由對液體中所包含之微小氣泡施加高壓，並施加物理性刺激，而使微小氣泡急遽地縮小。 [先前技術文獻] [專利文獻]As a currently known microbubble generating device, for example, the method and device described in Japanese Patent Application Laid-Open No. 2006-289183 are by supplying a liquid containing microbubbles to a storage tank and applying ultrasonic vibration to the liquid , It crushes the microbubbles in the liquid, and produces nanobubbles in the liquid. In addition, the device described in Japanese Patent Application Laid-Open No. 2012-250138 rapidly shrinks the microbubbles by applying high pressure to the microbubbles contained in the liquid and applying physical stimulation.

然而，關於上述之洗淨不能說是已被充分探討，在要求高衛生狀態的領域中，僅使用有微細氣泡的洗淨不能說是得到充分的效果。例如，日本特開2005-118462號公報中所記載之清洗裝置，於洗滌之前的清洗步驟中，係使用習知般包含清潔劑之洗淨液，並藉由習知般之水洗機來進行洗滌者。此外，於日本特開2007-83142號公報或日本特開2016-132712號公報中，係為了提高與被洗淨物之濕潤性而使用界面活性劑者，針對所選擇之界面活性劑的種類與微細氣泡的洗淨效果之加乘效應並無任何提案。However, it cannot be said that the above-mentioned cleaning has been fully explored. In the field where a high hygienic state is required, the cleaning using only fine bubbles cannot be said to be sufficient. For example, the cleaning device described in Japanese Patent Application Laid-Open No. 2005-118462 uses a conventional cleaning solution containing a cleaning agent in the cleaning step before washing, and is washed by a conventional washing machine. By. In addition, in Japanese Patent Laid-Open No. 2007-83142 or Japanese Patent Laid-Open No. 2016-132712, those who use surfactants to improve the wettability with the object to be cleaned are based on the type and type of surfactant selected. There is no proposal for the additive effect of the cleaning effect of fine bubbles.
如此般，於先前技術文獻之任一文獻中，針對微細氣泡所致之洗淨效果的提昇之機制並無充分闡明，此外，藉由微細氣泡與添加劑之組合而提昇洗淨效果等之用以提昇洗淨效果的各條件之闡明也不能說是充分。As such, in any of the prior art documents, the mechanism for improving the cleaning effect caused by fine bubbles is not fully elucidated. In addition, the combination of fine bubbles and additives is used to improve the cleaning effect. The elucidation of the conditions for enhancing the cleaning effect cannot be said to be sufficient.
如上述般，於因排水導致之對環境的負擔小，且對被洗淨物之物理性刺激少的洗淨方法、即採用微細氣泡的洗淨方法中，係要求不併用清潔劑等便具有與清潔劑同等或是高於清潔劑之洗淨力的水系組成物。As mentioned above, in a cleaning method that has a small burden on the environment due to drainage and less physical irritation to the object to be cleaned, that is, a cleaning method that uses fine bubbles, it is required that no detergent is used in combination. A water-based composition equal to or higher than the cleaning power of the detergent.
因而，本發明係目的在於，提供用於產生具有適於洗淨之所期望之特性的微細氣泡之水系組成物，進而，提供藉由使用該微細氣泡，而不論是對環境或洗淨對象物負擔皆比以往更少的洗淨方法。Therefore, the object of the present invention is to provide an aqueous composition for generating fine bubbles having desired characteristics suitable for washing, and further, to provide by using the fine bubbles, regardless of the environment or the object to be cleaned. The cleaning method is less burdensome than before.
此外，用以產生如此之微細氣泡的裝置，係需要高壓泵或大型的裝置，因此，存在有設置空間或導入成本增加的問題。此外，在利用習知的裝置使用省空間低成本之小型泵的情況時，由於水量及水壓方面有所限制，因此存在有無法充分得到微細氣泡之產生的問題。In addition, the device for generating such fine bubbles requires a high-pressure pump or a large-scale device. Therefore, there is a problem of increased installation space and introduction cost. In addition, in the case of using a small pump with space saving and low cost using a conventional device, there is a problem that the generation of fine bubbles cannot be sufficiently obtained due to limitations in water volume and water pressure.
因而，要求有即使為比習知的裝置更低的水壓及更少的水量也可產生所期望的量之微細氣泡的小型且低成本的微細氣泡產生裝置。Therefore, there is a demand for a small and low-cost microbubble generating device that can generate a desired amount of microbubbles even at a lower water pressure and a smaller amount of water than conventional devices.
本發明人等為了解決上述問題而苦心探討的結果，完成用以產生洗淨用之微泡的水系組成物，該微泡係在氣泡產生時具有比通常之水使用時更小的粒徑，其後若暫時放置，則具有比通常之水使用時更大的粒徑。此外，亦完成使用有如以上方式所得之微泡的有效洗淨方法。As a result of painstaking research in order to solve the above-mentioned problems, the inventors completed an aqueous composition for generating microbubbles for cleaning, which have a smaller particle size when bubbles are generated than when water is used normally. If left temporarily thereafter, it will have a larger particle size than normal water use. In addition, an effective cleaning method using the microbubbles obtained as above has also been completed.
再者，本發明人等完成無須大型的泵而可以小型且低成本，產生氣泡徑充分小，且氣泡密度高的微細氣泡的裝置。此外，亦完成使用有如此之裝置的微細氣泡之製造方法。Furthermore, the inventors of the present invention have completed a device that can be small and low-cost without requiring a large-sized pump, and generates fine bubbles with a sufficiently small bubble diameter and high bubble density. In addition, a method of manufacturing fine bubbles using such a device has also been completed.

本發明之微細氣泡產生裝置，係藉由使用本發明人等所發明的氣泡產生機構，即使為比習知的裝置更低的壓力及更少的水量也可產生所期望之粒徑及濃度的微細氣泡，因而，可提供小型且低成本的微細氣泡產生裝置。The micro-bubble generating device of the present invention uses the bubble generating mechanism invented by the inventors. It can generate the desired particle size and concentration even at a lower pressure and a smaller amount of water than conventional devices. With fine bubbles, it is possible to provide a small and low-cost fine bubble generating device.
此外，本發明人等發現藉由將本發明人等所發明的氣泡產生機構、與渦流產生機構、及大徑氣泡分離機構組合，而可更有效率地產生微細氣泡。In addition, the inventors found that by combining the bubble generating mechanism invented by the inventors, the vortex generating mechanism, and the large-diameter bubble separating mechanism, it is possible to generate fine bubbles more efficiently.
微細氣泡 微細氣泡係指直徑100μm以下的氣泡，其中，將直徑1～100μm之可目視的白濁之氣泡稱為微泡，將直徑1μm以下之無法目視的無色透明者稱為超微細氣泡。微泡與超微細氣泡之明確的差異在於，超微細氣泡不會將可見光散射因此肉眼無法直接觀察，微泡係因白濁而可確認存在。於本發明中，包含微泡之微細氣泡的產生確認，係藉由目視確認如此之白濁而進行。此外，針對超微細氣泡，係藉由以下詳述之雷射繞射而測定個數分布所致之粒度分布，而確認其存在。Fine bubbles Fine bubbles refer to bubbles with a diameter of 100 μm or less. Among them, those with a diameter of 1 to 100 μm that can be visually cloudy are called microbubbles, and those with a diameter of 1 μm or less that are invisible and colorless and transparent are called ultrafine bubbles. The clear difference between microbubbles and ultrafine bubbles is that ultrafine bubbles do not scatter visible light and therefore cannot be directly observed with the naked eye, and the presence of microbubbles can be confirmed due to turbidity. In the present invention, the confirmation of the generation of microbubbles including microbubbles is performed by visually confirming such white turbidity. In addition, for ultra-fine bubbles, the particle size distribution due to the number distribution is measured by the laser diffraction described in detail below to confirm their existence.
超微細氣泡之粒度分布測定方法 超微細氣泡之個數分布所致之粒度分布測定係在以下的條件下進行。 分析裝置：測定機器 Microtrac系列(microtrac version 10.5.3-22tR)(MicrotracBEL股份有限公司) 氣泡產生裝置：第4圖記載之裝置 氣泡產生溶媒：自來水(室溫)Method for measuring particle size distribution of ultra-fine bubbles The particle size distribution measurement due to the number distribution of ultra-fine bubbles is carried out under the following conditions. Analysis device: Measuring device Microtrac series (microtrac version 10.5.3-22tR) (MicrotracBEL Co., Ltd.) Bubble generating device: the device described in Figure 4 Bubble generating solvent: tap water (room temperature)
毫米氣泡・次毫米氣泡 於本發明中，毫米氣泡係指1～100mm之氣泡，次毫米氣泡係指100μm～1mm之氣泡。於本發明中，該等氣泡之產生確認，係藉由目視確認而進行。Millimeter bubbles, sub-millimeter bubbles In the present invention, millimeter bubbles refer to bubbles of 1-100 mm, and sub-millimeter bubbles refer to bubbles of 100 μm to 1 mm. In the present invention, the confirmation of the generation of the bubbles is performed by visual confirmation.
如此般微小的微細氣泡，相較於通常的氣泡，具有各種特徵性的性質，尤其，相較於通常的氣泡，在相同的容積之微細氣泡下比表面積較大，因此，在氣液界面之作用面的物理性吸附力非常大。Compared with ordinary bubbles, such tiny bubbles have various characteristic properties. In particular, compared with ordinary bubbles, they have a larger specific surface area under the same volume of microbubbles. Therefore, in the gas-liquid interface The physical adsorption force of the acting surface is very large.
此外，微細氣泡的特徵之一係具有自我加壓效果。亦即，微細氣泡在液體中為大致球形的氣泡，但，表面張力會作用於其氣液界面。因此，已知氣泡直徑越小，氣泡的內壓越高，隨著時間經過氣泡會在液中消滅。於本發明中，著眼於藉由在包含後述般之添加劑的水系組成物中產生微細氣泡，氣泡(bubble)係產生之後即具有小的粒徑，其後，進行凝聚而成為具有更大的粒徑。接著，令人驚訝地得知，藉由以如此之微細氣泡長時間存在於水系組成物的狀態，使該水系組成物接觸被洗淨物，而無須使用清潔劑等，即可發揮與使用清潔劑時同等或高於清潔劑之洗淨效果。以下，針對添加於水系組成物之添加劑進行說明。In addition, one of the characteristics of fine bubbles is that they have a self-pressurizing effect. That is, the fine bubbles are roughly spherical bubbles in the liquid, but surface tension acts on the gas-liquid interface. Therefore, it is known that the smaller the bubble diameter, the higher the internal pressure of the bubble, and the bubble will disappear in the liquid over time. In the present invention, attention is paid to the generation of fine bubbles in an aqueous composition containing additives as described below. The bubbles have a small particle size after they are generated, and thereafter aggregate to become larger particles. path. Then, it was surprisingly learned that by making such fine bubbles exist in the water-based composition for a long time, the water-based composition is brought into contact with the object to be cleaned, and the cleaning agent can be used and cleaned without the use of detergents. The cleaning effect of the cleaning agent is equal to or higher than that of the cleaning agent. Hereinafter, the additives added to the water-based composition will be described.
添加劑 添加劑，係指藉由於某素材中添加既定量的成分，而具有改善該素材之安定性或物理性狀等的功能之劑。作為本發明之添加劑，並無限定於該等，但，亦可包含選自由界面活性劑、乳化劑、增黏劑、安定劑所組成之群中的1種以上者。此外，亦可依期望，除了該等之1種以上的添加劑以外，雖不限定於以下者，但包含pH調整劑、保濕劑等。additive Additives refer to agents that have the function of improving the stability or physical properties of a material by adding a predetermined amount of ingredients to the material.

藉由氣泡產生機構22而成為包含氣泡的混合流體之水系組成物，係從氣液流入管21的端部排出，被導入氣液混相流產生機構25的下槽部23a，接著，通過渦流產生機構24的貫通孔28，被導入氣液混相流產生機構25的上槽部23b。貫通孔28，由於是如上述般地被設置成於剖面方向為傾斜，因此若包含氣泡之水系組成物通過該貫通孔28，則包含氣泡之水系組成物係在上槽部23b內成為渦流。在上槽部23b中以氣液流入管21的氣泡為中心製造漩渦，此時，包含比重輕且大直徑的氣泡之水系組成物會集中於上槽部23b的內側(圓筒形狀之中心側)，而被分離至上槽部23b的上部，另一方面，包含小直徑的氣泡之水系組成物會因離心力而被擠出至上槽部23b的外側(圓筒形狀之外周側)。如此一來，產生包含多量直徑小的氣泡之水系組成物，通過設置於氣液混相流產生機構25的側面之排出管26來排出。

For washing, any water such as tap water, well water, and hot spring water can be used.
洗淨效果之評估方法 各樣品之洗淨效果係藉由洗淨效果值進行評估。洗淨效果值係藉由由樣品之影像數據將污染度數值化(灰階)而算出。Evaluation method of cleaning effect The cleaning effect of each sample was evaluated by the cleaning effect value.

[Example]
根據以下的例子來具體地說明本發明，但，本發明係並不限定於該等例子。The present invention will be specifically explained based on the following examples, but the present invention is not limited to these examples.
實施例1 微細氣泡之洗淨能力試驗1 使用豬皮試料作為被洗淨物，如下述般地進行使用本發明之微細氣泡產生用水系組成物所產生之微細氣泡的洗淨能力試驗。Example 1 Washing ability test of fine bubbles 1 Using a pigskin sample as the object to be cleaned, a cleaning ability test of the fine bubbles generated using the water-based composition for generating fine bubbles of the present invention was performed as follows.
試驗條件 (1)試料 豬皮：裁切皮革 鞣製皮革(craft flower)(淡茶色豬皮)無花紋 裁切成2cm×2cm 人造污垢：巧克力用色素10wt%、山梨醇酐單棕櫚酸酯25wt% 食用大豆油65wt% (2)洗淨試驗之條件 水槽容積：4L 水溫：40℃ 檢體數：各3次 分別準備於自來水中以0.01質量%、0.005質量%、0.002質量%之濃度添加有酪蛋白鈉者各3個。作為對照，準備於自來水中產生微細氣泡者與未產生微細氣泡的自來水。Test conditions (1) Sample Pigskin: Cut leather, tanned leather (craft flower) (light brown pigskin) without pattern, cut into 2cm×2cm Artificial dirt: 10wt% of chocolate pigment, 25wt% of sorbitan monopalmitate Edible soybean oil 65wt% (2) Conditions for washing test Tank volume: 4L Water temperature: 40℃ Number of samples: 3 times each Prepare 3 cases each with sodium caseinate added in tap water at concentrations of 0.01% by mass, 0.005% by mass, and 0.002% by mass. As a control, a person who generated fine bubbles in tap water and a tap water that did not generate fine bubbles were prepared.
試驗程序
(1)以顯微鏡拍攝豬皮的表面。
(2)於豬皮表面將3.5mg/cm2
的人造污垢以藥匙延展附著，以顯微鏡拍攝表面。
(3)於使用包含1個圓錐形狀之氣泡產生機構22之本發明等人的發明之第4圖所記載的微細氣泡產生裝置20所產生的氣泡溶液中浸漬既定的時間(5分鐘)。
作為對照，在產生了微細氣泡的自來水與未產生微細氣泡的自來水中同樣地浸漬5分鐘。另外，未產生微細氣泡的自來水，於試驗中，係藉由泵使水循環。
(4)以紙巾輕輕吸取表面的水氣。
(5)在確認豬皮完全乾燥之後，以顯微鏡拍攝表面。Test procedure (1) Photograph the surface of pig skin with a microscope. (2) Spread and attach 3.5 mg/cm 2 of artificial dirt on the surface of pigskin with a spoon, and photograph the surface with a microscope. (3) Immerse in the bubble solution generated by the fine
洗淨效果 將針對各試料之洗淨前及洗淨後的試料之照片記載於第1圖。如由照片得以明瞭般，於不含酪蛋白鈉的對照樣品中，無論是產生了微細氣泡者，或未產生微細氣泡者，幾乎皆無確認到洗淨效果。 另一方面，針對藉由在包含酪蛋白鈉的水中所產生的微細氣泡進行洗淨後的試料，於所有的試料中都確認到洗淨效果。尤其，酪蛋白鈉的濃度越高，洗淨效果也越高。Washing effect The photos of each sample before and after washing are shown in Fig. 1. As can be seen from the photos, in the control sample without sodium caseinate, almost no cleaning effect was confirmed whether it was those with or without microbubbles. On the other hand, for the samples cleaned by the fine bubbles generated in the water containing sodium caseinate, the cleaning effect was confirmed in all the samples. In particular, the higher the concentration of sodium caseinate, the higher the cleaning effect.
實施例2 微細氣泡之洗淨能力試驗2 試驗條件 作為試料，使用人的手背的皮膚(附著部分為5cm× 5cm)，作為人造污染物質，係使用10mg/cm3 的油酸96.8質量%、sudanIV(油紅)2.2質量%，除此之外，以與實施例1相同方式進行。Example 2 Washing ability test of fine bubbles 2 Test conditions As a sample, the skin of the back of a human hand (attached part is 5cm×5cm) was used, and as an artificial pollutant, 10mg/cm 3 of oleic acid 96.8% by mass, sudan IV (Oil Red) 2.2% by mass, except that it was performed in the same manner as in Example 1.
洗淨效果之評估指標 作為添加有各添加劑之情況的洗淨效果之評估指標係使用洗淨效果值。洗淨效果值係如下述般地算出。 式：(洗淨前的灰階值)-(洗淨後的灰階值) 此外，灰階值係使用影像處理軟體來自動算出。具體而言係如以下所述。 1.於封住縫隙以避免外部環境的光進入，設置燈並使亮度為一定的箱內，設置附著有污染物質的試料。 2.拍攝1.調製出的試料。此時，在每1個洗淨條件下使用6個試料來實施試驗，且針對相同試料，進行3次反覆拍攝(合計18張)。 3.洗淨後的試料亦相同地以1及2的程序進行拍攝。 4.針對所得到的影像，使用影像處理軟體之GIMP來測定灰階。 5.針對所得到的灰階，將各試料之3次反覆平均化，並且比較洗淨前後6個試料的平均值。將此時之洗淨前後的灰階值之差作為洗淨效果值。此外，當洗淨評估值為3以上，且將3次反覆之平均值作為各檢體的灰階時，藉由T檢定算出比較洗淨前後時之有意水準，而將p＜0.05者視為具有有意差。Evaluation index of cleaning effect The cleaning effect value is used as an evaluation index of the cleaning effect when each additive is added. The cleaning effect value is calculated as follows. Formula: (Grayscale value before washing)-(Grayscale value after washing) In addition, the grayscale value is automatically calculated using image processing software. Specifically, it is as follows. 1. To seal the gap to prevent light from the external environment from entering, set up a lamp and set the brightness of the box to set the sample with contaminants attached. 2. Shoot the sample prepared by 1. At this time, the test was carried out using 6 samples per one washing condition, and the same sample was repeatedly photographed three times (18 photos in total). 3. The cleaned sample is also photographed using procedures 1 and 2. 4. For the obtained image, use the image processing software GIMP to determine the gray level. 5. Regarding the obtained gray scale, the 3 times of each sample are repeatedly averaged, and the average value of the 6 samples before and after washing is compared. The difference between the gray scale values before and after the cleaning at this time is taken as the cleaning effect value. In addition, when the cleansing evaluation value is 3 or more, and the average of the three iterations is used as the gray scale of each sample, the T test is used to calculate the intentional level before and after the cleansing, and p<0.05 is regarded as There is a deliberate difference.
針對以如此方式所算出的洗淨效果值，未達4係視為無洗淨效果，4～7係視為有洗淨效果，尤其是7.1以上係視為洗淨效果良好。另外，未達3或是3以上，當將3次反覆之平均值作為各檢體的灰階時，比較洗淨前後時之優勢水準為p＞0.05者係視為無效果。Regarding the cleansing effect value calculated in this way, the cleansing effect is considered to be no cleansing effect if it does not reach 4 series, the cleansing effect is considered to be 4-7 series, especially the cleansing effect is good when the cleansing effect is higher than 7.1. In addition, if it is less than 3 or more than 3, when the average value of 3 iterations is used as the gray scale of each sample, the comparison of the predominance level before and after washing is p>0.05 is regarded as no effect.
試驗結果 (1)洗淨效果 將洗淨試驗之結果記載於以下之表1。關於針對各添加劑之發揮洗淨效果的添加濃度之最小值進行探討。在針對酪蛋白鈉為0.008質量%、針對聚氧乙烯十二烷基醚為0.003質量%、針對大豆卵磷脂為0.01質量%、針對皂素為0.01質量%、針對硬脂基三甲基銨為0.01質量%以上的濃度之情況時，可確認洗淨效果。test results (1) Washing effect The results of the washing test are shown in Table 1 below. Discuss the minimum concentration of each additive to exert the cleaning effect. It is 0.008% by mass for sodium casein, 0.003% by mass for polyoxyethylene lauryl ether, 0.01% by mass for soy lecithin, 0.01% by mass for saponin, and for stearyl trimethyl ammonium When the concentration is 0.01% by mass or more, the cleaning effect can be confirmed.
實施例3 微細氣泡之洗淨能力試驗3
除了包含2個圓錐形狀之氣泡產生機構22以外，以與實施例1相同方法，進行微細氣泡之洗淨能力試驗。
其結果，僅在使用酪蛋白鈉作為添加劑的情況，相較於使用藉由圓錐為1個的實施例1之裝置所產生的微細氣泡的情況，其發揮洗淨能力的添加劑濃度之最小值變低。
具體而言，效果顯現的最小量為0.004質量%(洗淨值＝5.8)，其以下皆無洗淨效果。此外，於本實施例的情況中，酪蛋白鈉之濃度為0.008質量%時，洗淨值成為8.5，相較於實施例1變高。
其係藉由圓錐機構增加為2個，而使所產生之微細氣泡的量增加之故。Example 3 Washing ability test of fine bubbles 3
Except for the inclusion of two conical
實施例4 微細氣泡之粒徑測定 (1)粒徑測定條件 測定機器 Microtrac系列(microtrac version 10.5.3-225R) 光學台：MT3000IIExample 4 Measurement of particle size of fine air bubbles (1) Particle size measurement conditions Measuring machine Microtrac series (microtrac version 10.5.3-225R) optical table: MT3000II
(2)粒徑測定方法
本發明等人之發明之藉由上述的微細氣泡產生裝置20，而在添加有0.01質量%之作為本發明之添加劑的1種之酪蛋白鈉的水中產生微細氣泡。以上述之測定條件來測定該裝置運轉5分鐘後及停止5分鐘後的樣品之粒徑。(2) Particle size measurement method
In the invention of the present invention, the above-mentioned
(3)粒徑測定結果 將本發明之添加劑當中，在添加酪蛋白鈉所產生之微細氣泡及在無添加添加劑的自來水中所產生之微細氣泡之微細氣泡產生裝置運轉開始5分鐘後及該裝置停止後5分鐘後的最頻粒徑、平均粒徑及中值粒徑之測定值記載於以下之表2。(3) Particle size measurement results Among the additives of the present invention, the fine bubbles generated by the addition of sodium caseinate and the fine bubbles generated in the tap water without the additive are the most after 5 minutes after the start of operation and 5 minutes after the device is stopped. The measured values of the frequency particle size, average particle size and median particle size are described in Table 2 below.
於無添加酪蛋白鈉時，在微細氣泡產生裝置運轉5分鐘後起至微細氣泡產生後放置5分鐘後為止，最頻粒徑並無變化，平均粒徑及中值粒徑減少。另一方面，於添加酪蛋白鈉時，在微細氣泡產生裝置運轉5分鐘後起至微細氣泡產生後放置5分鐘後為止，最頻粒徑、平均粒徑、中值粒徑任一者皆增加。 此外，可確認到，於無添加酪蛋白鈉時，因時間經過而氣泡會縮小。另一方面，於添加酪蛋白鈉時，相較於無添加酪蛋白鈉時，產生後5分鐘後的粒徑減少。另一方面，運轉後放置5分鐘後的粒徑增加。Without the addition of sodium caseinate, after the micro-bubble generator operates for 5 minutes until the micro-bubbles are left for 5 minutes, there is no change in the most frequent particle size, and the average particle size and median particle size decrease. On the other hand, when sodium caseinate is added, any one of the most frequent particle size, average particle size, and median particle size increases after the micro bubble generator is operated for 5 minutes until the micro bubble is left for 5 minutes. . In addition, it can be confirmed that when sodium caseinate is not added, the bubbles shrink due to the passage of time. On the other hand, when sodium caseinate was added, the particle size after 5 minutes after generation was reduced compared to when sodium caseinate was not added. On the other hand, the particle size increased after being left for 5 minutes after operation.
實施例5 微細氣泡之粒徑經時變化 為了驗證各添加劑之洗淨效果與粒徑之經時變化的關連性，於與實施例1不同日，在分別以0.01質量%之濃度添加有添加劑的水中產生微細氣泡，測定微細氣泡產生裝置運轉開始5分鐘後及該裝置停止後5分鐘後的中值粒徑。將該等結果記載於以下之表3。Example 5 Changes in the particle size of fine air bubbles over time In order to verify the correlation between the cleaning effect of each additive and the change in particle size over time, on a different day from Example 1, fine bubbles were generated in water with additives added at a concentration of 0.01% by mass, and the operation of the fine bubble generator was measured. The median particle size 5 minutes after the start and 5 minutes after the device stopped. These results are described in Table 3 below.
於開始5分鐘後，在包含酪蛋白鈉作為添加劑的情況時，具有約10μm～65μm之中值粒徑，此外，在包含聚氧乙烯十二烷基醚或三甲基硬脂基三甲基銨作為添加劑的情況時，具有約0.5μm～65μm之中值粒徑。此外，於停止5分鐘後，具有約40μm～90μm之中值粒徑。任一者粒徑皆比實施例3更小，其係由於提高所使用的泵之水量，結果產生多數個具有較小的粒徑之氣泡之故。 在無添加添加劑之自來水中產生的氣泡之粒徑會經時性縮小。其係如在該技術領域中所得知般，因微細氣泡之自我收縮(自我加壓效果)所導致者。 群1之酪蛋白鈉及大豆卵磷脂、以及群2之聚氧乙烯十二烷基醚及硬脂基三甲基氯化銨，係氣泡產生裝置運轉開始5分鐘後的粒徑比無添加時更小。然而，在添加有該等添加劑的情況時，與無添加時不同，粒徑經時性變大。 群3之皂素及1-辛烷磺酸鈉，與無添加時相同地，粒徑經時性變小。After 5 minutes from the beginning, when sodium caseinate is included as an additive, it has a median particle size of about 10 μm to 65 μm. In addition, when it contains polyoxyethylene lauryl ether or trimethylstearyl trimethyl When ammonium is used as an additive, it has a median diameter of about 0.5 μm to 65 μm. In addition, it had a median particle size of about 40 μm to 90 μm after stopping for 5 minutes. The particle size of any one is smaller than that of Example 3. This is due to the increase of the water volume of the pump used, resulting in the generation of many bubbles with smaller particle sizes. The particle size of bubbles generated in tap water without additives will decrease over time. It is caused by the self-contraction (self-pressurizing effect) of fine bubbles as known in this technical field. Sodium casein and soybean lecithin of group 1, and polyoxyethylene lauryl ether and stearyl trimethyl ammonium chloride of group 2, the particle size of the bubble generator 5 minutes after the start of operation is higher than that of no addition smaller. However, when these additives are added, unlike the case of no addition, the particle size becomes larger with time. The saponin of group 3 and sodium 1-octane sulfonate have the same particle size as when they are not added.
考察
在添加有酪蛋白鈉的情況時，平均粒徑隨著時間經過而變大的原因，推測可能是酪蛋白本身所具有的凝聚之性質的影響。
此外，雖不限制於以下的理論，但使油脂附著於壓克力板，放進微細氣泡溶液內時，觀察氣泡進入油脂內部的樣子(第2圖)，因而推測可能是氣泡會進入油脂內部並凝聚，藉此擴大，使浮力增大，而將油脂從豬皮剝離。尤其，可推測在粒徑縮小至微米水準的群1及粒徑縮小至奈米水準的群2之添加劑的添加時，由於微細氣泡產生後之粒徑便比無添加時更小，因此較容易進入油脂內部，其後凝聚而粒徑增大，藉此提高浮力，使污垢剝離，而洗淨力上昇。也就是說，可推測若將具有附著物11之被洗淨物10浸漬於包含在水槽12內產生之微細氣泡13的水中，則小徑的微細氣泡會進入附著物11內，在該附著物11內凝聚，藉由凝聚後的微細氣泡14而得到浮力15，使附著物11上浮而將附著物從被洗淨物11剝離(第3圖)。因而，認為是藉由與以往使用有界面活性劑之洗淨方法完全不同的作用，而將污垢從被洗淨物剝離。Survey
When sodium caseinate is added, the average particle size becomes larger with the passage of time, presumably because of the agglomeration nature of casein itself.
In addition, although not limited to the following theory, when the grease is attached to the acrylic plate and put into the fine bubble solution, observe how the bubbles enter the grease (Figure 2), so it is speculated that the bubbles may enter the grease. And agglomerate, thereby expand, increase buoyancy, and peel off the fat from pigskin. In particular, it can be inferred that when adding the additives of Group 1 whose particle size is reduced to the micron level and Group 2 whose particle size is reduced to the nanometer level, the particle size after the generation of fine bubbles is smaller than when there is no addition, so it is easier It enters into the grease and then aggregates to increase the particle size, thereby increasing the buoyancy, peeling off the dirt, and increasing the cleaning power. In other words, it can be inferred that if the
與無添加添加劑時相同地，具有粒徑經時性縮小之傾向的群3之添加劑當中，1-辛烷磺酸鈉的洗淨值高的原因在於，即使在不併用微細氣泡的狀態亦具有高洗淨力，因此，原本此組成物所具有的洗淨力便高之故。The reason why the cleaning value of sodium 1-octane sulfonate is high among the additives of group 3, which has a tendency to decrease in particle size over time, is that it has a high cleaning value even when fine bubbles are not used together. High detergency, therefore, the original detergency of the composition is high.
因而，得知使用本發明之水系添加劑所產生的微細氣泡，相較於不使用添加劑所產生的氣泡，洗淨力較優異。Therefore, it is known that the fine bubbles generated by using the water-based additive of the present invention have superior cleaning power compared to the bubbles generated without using the additive.
實施例6 氣泡產生機構及渦流產生機構之構造的差異導致之氣泡產生的差異 對氣泡產生機構及渦流產生機構之形狀或有無造成之對氣泡產生狀況的影響進行試驗。 (1)氣泡產生機構 作為使用於本發明之氣泡產生裝置的氣泡產生機構，使用圓錐形狀且以180°之角度(亦即，夾著中心之相反側)設有2個孔者(高度：25 mm、底面內徑：16 mm、孔徑：2mm)。此外，作為其他形狀之氣泡產生機構的例子，係使用長方體形狀(高度：25 mm、縱：10 mm、橫：10mm)，且以180°之角度(亦即，相對向的平面上)設有2個孔者。於無氣泡產生機構的例子中，係於中槽部與下槽部之邊界平面上配置有2個相同直徑的孔。 (2)渦流產生機構 針對使用於本發明之微細氣泡產生裝置的渦流產生機構，係使2個管(外管內徑：17 mm、外管長度：75 mm、內管內徑：17 mm、內管長度：75mm、螺旋節距：15mm、螺旋溝槽寬：10mm、螺旋部長度：55mm)之內、口徑大的外管(裙部)變化來比較氣泡之產生狀況。具體而言，使用將裙部於從中槽部的最下端起5mm上錯開地配置者作為通常的裙部，作為其他形態的例子係使用無裙部者，及裙部的長度為一半者。 (3)程序 使用泵(淺野製作所製)，以8.9L/分之輸出於本發明之微細氣泡產生裝置導入水，在裝有10L之水(自來水、室溫)的水槽內產生微細氣泡。在裝置運轉開始後1分鐘停止，調查氣泡之產生狀況。針對微細氣泡之產生狀況係以目視進行。 (4)結果 將氣泡之產生結果彙整於以下之表4。Example 6 Difference in bubble generation caused by the difference in the structure of the bubble generating mechanism and the vortex generating mechanism Test the influence of the shape of the bubble generating mechanism and the vortex generating mechanism on the bubble generation condition. (1) Bubble generating mechanism As the air bubble generating mechanism used in the air bubble generating device of the present invention, a conical shape with two holes provided at an angle of 180° (that is, sandwiching the opposite side of the center) is used (height: 25 mm, bottom inner diameter: 16 mm, aperture: 2mm). In addition, as an example of a bubble generating mechanism of other shapes, a rectangular parallelepiped shape (height: 25 mm, length: 10 mm, and width: 10 mm) is used, and is provided at an angle of 180° (that is, on an opposing plane) 2 holes. In the example of no bubble generating mechanism, two holes of the same diameter are arranged on the boundary plane between the middle groove portion and the lower groove portion. (2) Eddy current generating mechanism For the vortex generating mechanism used in the fine bubble generating device of the present invention, two tubes (outer tube inner diameter: 17 mm, outer tube length: 75 mm, inner tube inner diameter: 17 mm, inner tube length: 75 mm, Spiral pitch: 15mm, spiral groove width: 10mm, spiral section length: 55mm), the outer tube (skirt) with a large diameter changes to compare the generation of bubbles. Specifically, a skirt part is used as a normal skirt part that is staggered 5 mm from the lowermost end of the middle groove part. As an example of other forms, a skirt part is used and a skirt part is half the length. (3) Procedure Using a pump (manufactured by Asano Manufacturing Co., Ltd.), water was introduced into the fine bubble generating device of the present invention at an output of 8.9 L/min, and fine bubbles were generated in a water tank containing 10 L of water (tap water, room temperature). Stop the device 1 minute after the start of operation, and investigate the occurrence of air bubbles. The production of fine bubbles is done visually. (4) Results The results of bubble generation are summarized in Table 4 below.
例6-1係使用圓錐作為產生機構，並將裙部(外管)於從第二槽部的下端起5mm上錯開配置者。使用本例之裝置來進行試驗的結果，水槽內的水完全白濁，良好地產生微細氣泡。Example 6-1 uses a cone as the generating mechanism, and the skirt (outer tube) is staggered 5 mm from the lower end of the second groove. As a result of the test using the device of this example, the water in the water tank was completely cloudy and fine bubbles were generated well.
例6-2，係去除產生機構，裙部係與例6-1相同地設置者。使用本例之裝置來進行試驗的結果，無產生氣泡。於例6-1中係良好地產生微細氣泡，因此，得知於無圓錐形狀之產生機構就不會產生微細氣泡的條件下，藉由具有圓錐形狀之產生機構而會產生微細氣泡。因而，為了以更低的水壓及更少的水量產生微細氣泡，氣泡產生機構係發揮重要的功用。Example 6-2 is to remove the generating mechanism, and the skirt is set in the same way as in Example 6-1. As a result of testing using the device of this example, no bubbles were generated. In Example 6-1, fine bubbles are generated well. Therefore, it is known that the generation mechanism having a conical shape will generate fine bubbles under the condition that the generating mechanism without a cone shape does not generate fine bubbles. Therefore, in order to generate fine bubbles with lower water pressure and less water volume, the bubble generating mechanism plays an important role.
例6-3，係將產生機構之形狀設為長方體，裙部係與例6-1相同地設置者。使用本例之裝置來進行試驗的結果，雖觀察到微細氣泡之產生，但濃度低，水槽內的水未達完全白濁。因而，認為作為氣泡產生機構之形狀，相較於長方體，圓錐者較佳。In Example 6-3, the shape of the generating mechanism is a rectangular parallelepiped, and the skirt is set in the same manner as in Example 6-1. As a result of testing with the device of this example, although the generation of fine bubbles was observed, the concentration was low and the water in the tank was not completely cloudy. Therefore, it is considered that the shape of the bubble generating mechanism is better than the rectangular parallelepiped, the cone.
例6-4，產生機構係與例6-1相同地使用圓錐，且去除裙部者。使用本例之裝置來進行試驗的結果，產生直徑大的毫米氣泡，而非微細氣泡。此外，於例6-5中，將裙部的長度設為例6-1之一半的長度，結果所產生者大部分為毫米氣泡，微泡僅少量產生。由該等結果，裙部會防止阻礙微細氣泡化的浮力強的大尺寸之空氣塊流入渦流產生機構及圓錐形狀的氣泡產生機構。In Example 6-4, the production mechanism is the same as that in Example 6-1, using a cone and removing the skirt. As a result of the test using the device of this example, millimeter bubbles with a large diameter are generated instead of fine bubbles. In addition, in Example 6-5, the length of the skirt is set to half the length of Example 6-1. As a result, most of the generated ones are millimeter bubbles, and only a small amount of microbubbles are generated. As a result of these results, the skirt prevents the buoyant, large-sized air block that prevents the formation of fine bubbles from flowing into the vortex generating mechanism and the conical bubble generating mechanism.
實施例7 圓錐形狀之氣泡產生機構對產生極限壓力所造成的影響 為了驗證本發明之微細氣泡產生裝置的產生機構對氣泡產生的極限壓力之效果，對於去除圓錐形狀之產生機構者，與通常具備有圓錐形狀之產生機構者，改變導入裝置的水量來比較微細氣泡之產生狀況。針對圓錐之有無與導入之水量以外的條件，係以與實施例6之例6-1相同的條件進行試驗。將結果記載於以下之表5。Example 7 The influence of the conical bubble generating mechanism on the ultimate pressure In order to verify the effect of the generating mechanism of the fine bubble generating device of the present invention on the ultimate pressure of the bubble generation, for those that remove the cone-shaped generating mechanism, and those that usually have a cone-shaped generating mechanism, change the amount of water introduced into the device to compare the fine bubbles The production status. The conditions other than the presence or absence of cones and the amount of water introduced were tested under the same conditions as in Example 6-1 of Example 6. The results are shown in Table 5 below.
若使用圓錐作為產生機構，則相較於不使用圓錐的情況，以較低水壓、較低水量產生微細氣泡。因而，藉由使用本發明之圓錐形狀之產生機構，無須藉由習知般之大型的泵來將水以高壓壓送至大型的裝置，因此，可以使用有小型的泵之小型的裝置來產生微細氣泡。If a cone is used as the generating mechanism, compared to the case where a cone is not used, fine air bubbles are generated with a lower water pressure and a lower water volume. Therefore, by using the cone-shaped generating mechanism of the present invention, there is no need to use a conventional large pump to pump water to a large device under high pressure. Therefore, a small device with a small pump can be used to produce Fine bubbles.
若使用本發明之氣泡產生裝置，則可以比習知裝置更低之0.1MPa的裝置入口壓力產生充分的濃度之微細氣泡。由於可以比習知更低的壓力產生充分使用於所習望之用途中的濃度，因此無須使用高壓之尺寸大的泵，而可提供設置空間或成本面上優異的微細氣泡產生裝置。If the bubble generating device of the present invention is used, the device inlet pressure of 0.1 MPa lower than that of the conventional device can generate sufficient concentration of fine bubbles. Since it can generate a concentration that can be used for the desired purpose at a lower pressure than the conventional one, there is no need to use a high-pressure and large-sized pump, and a fine bubble generating device with excellent installation space and cost can be provided.
此外，將泵之輸出提高的結果，以輸出 9.2L/分(裝置入口壓力 0.16MPa)、輸出 16L/分(裝置入口壓力 0.2MPa)、及輸出 22L/分(裝置入口壓力 0.25MPa)產生微細氣泡。使用更大型的泵來將輸出提高至68L/分的結果，裝置入口壓力雖上昇至1MPa，但微細氣泡之產生濃度與本實施形態之使用泵來將輸出設為22L/分的情況同程度。因而，本發明之微細氣泡產生裝置，即使不使用大型泵，亦可以不遜色於習知大型裝置的程度產生微細氣泡。In addition, as a result of increasing the output of the pump, the output is 9.2L/min (device inlet pressure 0.16MPa), output 16L/min (device inlet pressure 0.2MPa), and output 22L/min (device inlet pressure 0.25MPa) to produce fine bubble. As a result of using a larger pump to increase the output to 68L/min, although the inlet pressure of the device rises to 1MPa, the concentration of the generation of fine bubbles is the same as the case of using the pump to set the output to 22L/min in this embodiment. Therefore, the fine bubble generating device of the present invention, even if a large pump is not used, can generate fine bubbles at a level not inferior to conventional large devices.
實施例8 圓錐上之孔的位置及個數對氣泡產生所造成的影響 針對本發明之氣泡產生機構之孔的位置及個數對氣泡之產生狀況所造成的影響進行驗證。孔的位置及個數，係如第7圖所示般，由a～f之參數規定。在此，a係從圓錐底部起至孔下端部為止之軸方向的距離、b係從圓錐頂部起至孔上端部為止之軸方向的距離、c係孔的個數、d係孔的內徑、e係圓錐底部的內徑、f係圓錐部之軸方向的長度、g係孔的配置角度。孔的位置及個數以外係以與實施例1相同的條件進行試驗。將結果記載於以下之表6。Example 8 The position and number of holes on the cone affect the generation of bubbles The effect of the position and number of the holes of the bubble generating mechanism of the present invention on the bubble generation condition was verified. The position and number of holes are defined by the parameters a to f as shown in Figure 7. Here, a is the axial distance from the bottom of the cone to the lower end of the hole, b is the axial distance from the top of the cone to the upper end of the hole, c is the number of holes, and d is the inner diameter of the hole. , E is the inner diameter of the bottom of the cone, f is the axial length of the cone, and g is the arrangement angle of the hole. The test was performed under the same conditions as in Example 1 except for the position and number of holes. The results are shown in Table 6 below.
由該等結果，設置於圓錐的孔較理想為2個以上。此外，在設置2個以上的孔的情況時，可以45°～180°之角度設置。尤其，在設置2個孔的情況時，最佳係以180°設置。孔的尺寸，於本實施例中，雖將內徑設為1～4mm，但較佳的尺寸會因所設定的水量而變化，因此，必須適當調整。另外，雖於表中未顯示，但孔過多氣泡之產生會減弱，因此較佳為6個以下。From these results, the number of holes provided in the cone is preferably two or more. In addition, when two or more holes are installed, they can be installed at an angle of 45° to 180°. In particular, when two holes are provided, the best setting is 180°. The size of the hole, although the inner diameter is set to 1 to 4 mm in this embodiment, the preferred size will vary with the set water volume, so it must be adjusted appropriately. In addition, although it is not shown in the table, the generation of bubbles with excessive pores will be reduced, so it is preferably 6 or less.
此外，以與本實施例之8-1相同條件，將泵的輸出水量提高至22L/分為止的結果，孔的內徑至8mm為止可確認微細氣泡之充分的產生。進一步將孔的內徑設為10mm的結果，其濃度雖低但可確認微細氣泡之產生。因而，在使用於本發明之裝置的情況，作為設置於氣泡產生機構之圓錐部的孔之內徑，係以1～10mm為較佳的範圍。In addition, under the same conditions as 8-1 of this embodiment, as a result of increasing the output water volume of the pump to 22 L/min, the sufficient generation of fine bubbles can be confirmed until the inner diameter of the hole is 8 mm. Furthermore, when the inner diameter of the hole was 10 mm, the concentration was low, but the generation of fine bubbles was confirmed. Therefore, when used in the device of the present invention, the inner diameter of the hole provided in the conical part of the bubble generating mechanism is preferably in the range of 1 to 10 mm.

The measured values of the frequency particle diameter, the average particle diameter and the median particle diameter are described in Table 7 below.
如此般，可確認到使用本發明之第4圖所記載的微細氣泡產生裝置而產生微細氣泡。In this way, it can be confirmed that the microbubble generation device described in Fig. 4 of the present invention generates microbubbles.
實施例10 超微細氣泡產生試驗 確認在使用第4圖所記載的微細氣泡產生裝置的情況之伴隨著微細氣泡之產生的超微細氣泡之產生狀況。 (1)粒度分布測定條件 測定機器 Microtrac系列(microtrac version 10.5.3-225R) 光學台：UPA-UZ 水槽容積：4LExample 10 Ultrafine bubble generation test Confirm the generation of ultra-fine bubbles that accompany the generation of the micro-bubbles when using the micro-bubble generator described in Fig. 4. (1) Particle size distribution measurement conditions Measuring machine Microtrac series (microtrac version 10.5.3-225R) Optical table: UPA-UZ Water tank volume: 4L
(2)粒度分布測定方法 在自來水(室溫)中使第4圖所記載的裝置運轉，而產生氣泡。以上述之測定條件來測定該裝置之運轉5分鐘後及停止5分鐘後的樣品之0.800nm～6,540nm的測定範圍內之粒度分布(個數分布)。(2) Particle size distribution measurement method The device described in Figure 4 is operated in tap water (room temperature) to generate bubbles. The particle size distribution (number distribution) in the measurement range of 0.800nm to 6,540nm of the sample after 5 minutes of operation of the device and 5 minutes after stopping of the device was measured under the above measurement conditions.
(3)粒度分布測定結果 將在自來水中使氣泡產生裝置運轉之5分鐘後、停止5分鐘後的最頻粒徑、平均粒徑及中值粒徑之測定值記載於以下之表8。(3) Results of particle size distribution measurement The measured values of the most frequent particle diameter, average particle diameter, and median particle diameter after 5 minutes of operating the air bubble generator in tap water and 5 minutes after stopping are described in Table 8 below.
由上述的結果，可確認1μm(＝1000nm)以下之超微細氣泡之產生。此外，亦可確認於超微細氣泡上作為特徵性的舉動之經時性的粒徑之減少。為了產生超微細氣泡，通常，需要比微細氣泡之產生更大型且高額的裝置，因此，本發明之裝置，在具有非常小型且簡易的構造之點上，可說是非常優異。From the above results, it can be confirmed that ultra-fine bubbles below 1 μm (=1000 nm) are generated. In addition, it is also possible to confirm the time-dependent decrease in particle size, which is a characteristic behavior of ultrafine bubbles. In order to generate ultra-fine bubbles, generally, a larger and expensive device is required than the generation of fine bubbles. Therefore, the device of the present invention is very excellent in that it has a very small and simple structure.
