Description
本創作關於一種儲氣瓶，尤指用於儲存高壓氣體的儲氣瓶。This creation is about a gas cylinder, especially a gas cylinder used to store high-pressure gas.
目前主要的交通運輸工具是使用石油、煤炭等傳統化石能源。為了日常生活的便利性，交通運輸工具的使用量大幅成長，卻也伴隨了環境問題的產生。例如，汽車的內燃機在高溫燃燒及燃燒不完全的情況下所排放出的廢氣會增加溫室效應而導致全球暖化，且燃燒後產生的超細懸浮微粒（PM2.5）會使得空氣品質下降，同時危害人體健康。由於能源短缺和環境破壞已經發展成重要議題，使得依賴化石能源的習慣正在被扭轉，因此電動車和氫燃料電池車的開發成為相當具有潛力的未來趨勢。相較於電動車充電時間長、續航距離短的缺點，氫燃料電池雖然成本較高、加氫站更少，但使用方式卻更接近傳統內燃機汽車使用者的習慣；尤其是在需要長途行駛的大型客車、貨車等重車，氫燃料電池車的開發仍然方興未艾。在氫燃料電池中，氫氣做為燃料供應給燃料電池的陽極，但因為氫氣本身具有易燃、易***等特性，因此氫燃料電池是否能順利推廣的關鍵因素就在於氫的儲存安全性和運輸安全性。At present, the main means of transportation use traditional fossil energy such as oil and coal. For the convenience of daily life, the use of transportation tools has grown substantially, but it has also been accompanied by environmental problems. For example, the exhaust gas emitted by the internal combustion engine of a car in the case of high-temperature combustion and incomplete combustion will increase the greenhouse effect and cause global warming, and the ultrafine suspended particulates (PM2.5) produced after combustion will reduce the air quality. At the same time, it is harmful to human health. As energy shortages and environmental damage have become important issues, the habit of relying on fossil energy is being reversed. Therefore, the development of electric vehicles and hydrogen fuel cell vehicles has become a promising future trend. Compared with the shortcomings of long charging time and short battery life of electric vehicles, although hydrogen fuel cells are more costly and have fewer hydrogen refueling stations, their use methods are closer to the habits of users of traditional internal combustion engine vehicles; especially when driving long distances. The development of heavy vehicles such as large buses and trucks and hydrogen fuel cell vehicles is still in the ascendant. In the hydrogen fuel cell, hydrogen is used as the fuel to supply the anode of the fuel cell, but because hydrogen itself is flammable and explosive, the key factors for the smooth promotion of hydrogen fuel cells are the storage safety and transportation of hydrogen. safety.
目前儲氫方式可分為氣態儲氫、液態儲氫和固態儲氫，且在儲氫量大小、成本、操作難易程度、安全性、技術成熟度等方面各有優劣之處；其中，技術成熟的高壓氣態儲氫法雖然存在安全隱患，但由於成本低廉且運輸方便，目前仍佔據氫燃料電池車的發展主流。一般而言，儲存氫氣等氣體的儲氣瓶係由金屬或碳纖維纏繞形成瓶身主體。為了降低裝有易燃氣體的儲氣瓶在使用過程中遇到意外狀況而遭到燃燒，導致儲氣瓶結構被破壞而引爆易燃氣體的危險性，已有不少研究著重於改良儲氣瓶的瓶身材料或是瓶身的材料纏繞結構。然而，前述方法不僅使製程複雜化，且可能會提高製造成本，而不利於市場開發。At present, hydrogen storage methods can be divided into gaseous hydrogen storage, liquid hydrogen storage and solid hydrogen storage, and each has its own advantages and disadvantages in terms of hydrogen storage capacity, cost, ease of operation, safety, and technological maturity; among them, the technology is mature Although the high-pressure gaseous hydrogen storage method has potential safety hazards, it still occupies the mainstream of the development of hydrogen fuel cell vehicles due to its low cost and convenient transportation. Generally speaking, the gas cylinder for storing hydrogen and other gases is wound by metal or carbon fiber to form the main body of the bottle. In order to reduce the risk that gas cylinders containing flammable gas will be burned in unexpected situations during use, which will damage the structure of the gas cylinder and detonate the flammable gas, many studies have focused on improving the gas storage. The body material of the bottle or the material winding structure of the bottle body. However, the aforementioned method not only complicates the manufacturing process, but may also increase the manufacturing cost, which is not conducive to market development.
因此，若能以既有的儲氣瓶結構為基礎就可實現延緩儲氣瓶著火、阻止火勢持續蔓延、或增大絕熱性以延遲儲氣瓶的瓶身結構被破壞之目的，不僅可起到保護作用為現場人員的逃生或救災爭取到較長的反應時間，亦能有助於氫燃料電池車的推廣，共創節能社會。Therefore, if the existing gas cylinder structure can be used as the basis to achieve the purpose of delaying the ignition of the gas cylinder, preventing the continuous spread of the fire, or increasing the thermal insulation to delay the destruction of the cylinder body structure of the gas cylinder, not only can it be achieved In order to protect the personnel on the scene, they can obtain a longer response time for the escape or disaster relief, which can also help the promotion of hydrogen fuel cell vehicles and create an energy-saving society.

Carbon fiber is wound around the outer layer. Then, the fire-proof and heat-resistant resin composition of Example 1 was uniformly coated on the outer surface of the body of the container to form a coating; then, the coating was dried with hot air at a temperature of 80°C, Get a

為了測試防火阻熱層的阻熱能力，另將實施例1的防火阻熱樹脂組成物塗佈於一聚乙烯離型膜上形成一塗層，同樣於80°C的溫度下烘烤所述塗層30分鐘，待其完全固化，即可得到一防火阻熱層1A；其中，該防火阻熱層1A的平均厚度同樣為7 mm。In order to test the heat resistance capacity of the fire-resistant heat-resistant layer, the fire-resistant heat-resistant resin composition of Example 1 was also coated on a polyethylene release film to form a coating, and the same was baked at a temperature of 80°C. After the coating is completely cured for 30 minutes, a fire-resistant and heat-resistant layer 1A can be obtained; wherein the average thickness of the fire-resistant and heat-resistant layer 1A is also 7 mm.
首先，先將防火阻熱層1A固定於一固定架上，再於室溫下以本生燈對所述防火阻熱層1A進行防火測試。防火測試的方法如下：將防火阻熱層水平固定於一固定架上；火源係垂直設置於所述防火阻熱層的正下方，火源與防火阻熱層的外表面（即防火阻熱層靠近火源的一側）之距離為20 mm，火焰高度約為20 mm，所述火源以藍色內焰對所述防火阻熱層的外表面加熱，且火源的溫度為700°C。另外，以一溫度感測器貼附於防火阻熱層的內表面（即防火阻熱層遠離火源的一側，即相當於與儲氣瓶的瓶身主體的外表面接觸的防火阻熱層之表面），持續量測防火阻熱層的內表面之溫度。當火源開始加熱防火阻熱層時即啟動一計時器計時，直至防火阻熱層的內表面的溫度達到200°C，並記錄所需的加熱時間。經測試得知，防火阻熱層1A的內表面的溫度達到200°C需要9分24秒。因防火阻熱層1A與儲氣瓶1的防火阻熱層20皆是由實施例1的防火阻熱樹脂組成物所製備，且兩者的成形方式和所得的防火阻熱層之平均厚度相同，故能推知儲氣瓶1的防火阻熱層20在相同的防火測試方法下，防火阻熱層20的內表面的溫度達到200°C應同樣需要9分24秒。First, first fix the fire-resistant heat-resistant layer 1A on a fixing frame, and then perform a fire-proof test on the fire-resistant heat resistance layer 1A with a Bunsen burner at room temperature. The method of fire protection test is as follows: fix the fire resistance heat layer horizontally on a fixed frame; the fire source is vertically arranged directly under the fire resistance heat resistance layer, and the fire source and the outer surface of the fire resistance heat resistance layer (that is, the fire resistance heat resistance layer) The distance between the layer near the fire source) is 20 mm, and the flame height is about 20 mm. The fire source uses a blue inner flame to heat the outer surface of the fire resistance and heat resistance layer, and the temperature of the fire source is 700° C. In addition, a temperature sensor is attached to the inner surface of the fireproof heat resistance layer (that is, the side of the fireproof heat resistance layer away from the fire source, which is equivalent to the fireproof heat resistance that contacts the outer surface of the main body of the gas cylinder). The surface of the layer), continuously measure the temperature of the inner surface of the fire and heat resistance layer. When the fire source starts to heat the fire-resistant heat-resistant layer, a timer is started until the temperature of the inner surface of the fire-resistant heat-resistant layer reaches 200°C, and the required heating time is recorded. According to the test, it takes 9 minutes and 24 seconds for the temperature of the inner surface of the fireproof thermal resistance layer 1A to reach 200°C. Because the fireproof and heat-resistant layer 1A and the fireproof and heat-
由上述性能分析結果明顯可知，由實施例1製得之防火阻熱層能具有優異的防火阻熱效果，據此可見，本創作之具有防火阻熱層的儲氣瓶必然可提供足夠的保護性；當所述儲氣瓶在遇到撞擊、高溫或其他意外時，其具有的所述防火阻熱層可幫助延緩儲氣瓶的著火時間且能延遲儲氣瓶結構被破壞的時間，進而為現場人員的逃生或救災爭取到較長的反應時間，同時保證所述儲氣瓶於容納氫氣應用於氫燃料電池時，能具有更高的運輸安全性和儲存安全性，有助於氫燃料電池車的推廣。From the results of the above performance analysis, it is obvious that the fire-resistant heat-resistant layer prepared in Example 1 can have excellent fire-resistant and heat-resistant effects. Based on this, it can be seen that the gas cylinder with the fire-resistant and heat-resistant layer of this creation must provide sufficient protection When the gas cylinder encounters an impact, high temperature or other accidents, the fire and thermal resistance layer it has can help delay the ignition time of the gas cylinder and delay the time for the structure of the gas cylinder to be destroyed, thereby Gain a longer response time for the escape or disaster relief of on-site personnel, and at the same time ensure that the gas storage cylinder can have higher transportation safety and storage safety when the hydrogen is used in the hydrogen fuel cell, which is helpful for hydrogen fuel Promotion of battery cars.
