て提供した。(Prior art) Japanese Patent Laid-Open No. 2002-120007 discloses that water treatment with water-soluble glass containing monovalent silver ions (CAg) in its composition sterilizes and kills microorganisms, thereby preventing the growth of rot, slime, and algae. No. 62-210098. When using such a glass, the inventors of the present invention have designed the above-mentioned glass water using a water-permeable fiber cloth or the same synthetic resin sheet so that the elution of the glass components is ensured and sustained release is achieved without the glass becoming difficult to dissolve in water. Patent application was made in 1983 for an effective technology to wrap and immerse the treatment agent.

上の推論では帰納出来ない所である。Nowadays, people are becoming aware of the effects of boron on the human body (accumulating in the human body when drinking water) in water systems including drinking water, and the emergence of boron-free water-soluble glass is desired. - In contrast to water-soluble glass manufacturing technology and technology that can accurately elute Ag ions, which are active ingredients, from glass into water, we have developed conventionally known network-forming oxides and network-modifying oxides. The selection of combinations with oxides and the establishment of a blending range of oxides to achieve both water solubility and glass-forming properties require a lot of experimentation and research, and cannot be reduced to just theoretical reasoning. .

This is what we are trying to provide. Judging from its boron-free nature, it is estimated that the water treatment agent of the present invention can be used in water supply systems including drinking water in 8 tablets.

Ｈの反応当量との関係に於てｐＨ調整の役をなす。(Function) S i O, is a network-forming oxide and plays the role of transporting Ag+ ions from Ag2O into water by dissolving the network unit that makes up its structure in water, that is, silver is dissociated alone. It is not something that dissolves in water, but S i O
Both the network structure units of No. 2 are dissolved in water, and therefore, it is assumed that the original action of Ag+ ions, which is sterilization and microbial killing, is continuously guaranteed by the elution of SiO2 into water. Si(OH)4 produced by tazoshi hydrolysis acts as an acid, so NaO'
It plays a role in pH adjustment in relation to the reaction equivalent of H.

。こλよりＳ ｉ Ｏ，は５５〜８０％の範囲とする。However, if the SiO2 content is less than 55%, the glass becomes easy to melt and lacks a continuous network structure, resulting in small units of 8102, making it inconvenient to melt silver.At the same time, the increased Na and O contents cause water to melt. It tends to become alkaline. 5in2
If it exceeds 80%, the water solubility of the glass deteriorates, requiring a long time for melting or requiring extremely high temperature heating for production. From this λ, S i O, is in the range of 55 to 80%.

ことが判明した。On the other hand, Na and O are network-modifying oxides that take A g2O into the glass and ensure the water solubility of the glass.The reason for this is thought to be to break the continuous network structure of SiO2, but Na It has been found that when the amount of O increases, the solubility in water increases, and even solid glass becomes deliquescent, which is inconvenient for storage.Furthermore, it has been found that when the amount of O increases to 5° or more, it cannot be vitrified.

群の発生を防止し得たことからも実証される所である。Moreover, since NaOH produced by hydrolysis is strongly alkaline, it increases the pH of water, and is particularly unsuitable for water treatment where strong alkalis are prohibited, such as drinking water. Just to be sure, the permissible pH of drinking water is 5°8 to 8.6, so Na
For this reason, the use of large amounts of , ○ should be prohibited. Conversely, if the amount of Na2O is small, it becomes impossible to incorporate a large amount of Ag2O into the glass. From this point of view, Na, ○
is in the range of 19.5 to 42%. Ag2O is the main character of water-soluble glass for sterilization purposes, and as mentioned above, N
It is thought that due to the action of a2O, it is incorporated into the 5in2 glass as Ag2O, and in water it is dissolved as Ag+ ions together with the network structure unit of SiO2, but 2O. If it is less than 5%, the sterilizing and microbicidal effects of Ag ion cannot be expected, and if it exceeds 3%, it becomes difficult to dissolve it into the glass, leading to inconveniences in glass production. From this 1, Ag2O is set in the range of 0.5 to 3%. The water treatment agent of the present invention having the above-mentioned composition range can be used directly in water or in accordance with Japanese Patent Application No. 61-18305.
When wrapped in water-permeable fiber cloth or the same synthetic resin sheet and immersed as shown in 5, it acts as a sterilizer, slime-proof, and algae-proof due to the action of Ag bioions that are eluted into water, but it is especially boron-free, so it contains drinking water. It is meaningful when applied to water supply systems. The treatment effect of using the water treatment agent of the present invention is that, as will be clear from the examples described below, for example, the generation of coliform bacteria could be prevented even after more than 80 days when tap water was slowly and continuously introduced into the aquarium. This is also proven by this.
なお、Ａｇ２Ｏの原料としてはＡｇＮ○、を通常使用す

る働きがあることが判明した。即ち、Ａｌ２Ｏ。In order to incorporate a larger amount of Agzo into the glass network structure of the water-soluble glass of the present invention, it is necessary to increase the amount of Na2O, but if the amount of Na2O is too large, the glass will become deliquescent and will only cause problems in storage. As mentioned above, a large amount of NaOH is produced, which reduces the alkaline component and becomes strongly alkaline. However, later research experiments revealed that when Al2O is used, Ag2 is added to the glass network structure.
It was found that it has the function of incorporating a large amount of O and the function of reducing the deliquescent property of glass. That is, Al2O.

ａ度を増やすことが可能である。Due to the presence of Na2O and Agzo, the coordination number for oxygen is reduced from 6 to 4, making it easier to form a network structure,
At this time, Ag atoms and AI atoms combine to increase the concentration of Ag in the glass network structure and enhance the bactericidal and microbicidal effects of Ag+ ions, but since Al2O itself is a high melting point material, it should not be used in too large a quantity. When used, the melting temperature of the glass raw material increases, making it difficult to vitrify, and the water solubility of the glass deteriorates. According to the experiment, A1□
A suitable range for O1 is 0.5 to 30%. If it is less than 0.5%, little effect will be exhibited, and if it exceeds 30%, the above-mentioned problems will occur. Thus, Al2O is an effective glass component for increasing the Ag concentration in the glass network structure within a predetermined range and for alleviating the deliquescence of the glass. Part of Na2O is converted into K2O and or C
When replacing with aO, the amount of Ag in the glass is small compared to when N a2O is used as the sole alkali component.
It is possible to increase the a degree.

所に置いて、滞水状態の水の変化をｗｔ察した。Test I After pouring 250 mQ of tap water into a knee 300 mQ Erlenmeyer flask, 2 g of the water treatment agent lump of Example 4 wrapped in a synthetic fiber non-woven fabric was added (800 ppm) and placed in a sunny place. Changes in the water in the stagnant state were observed wt.

るものと思われる。Incidentally, five Zem pins were separately immersed in the Erlenmeyer flask to conduct a simple test for corrosion status. This simple test is a simple test for storing drinking water in places where tap water is not fully distributed, such as irregularly storing tap water on remote islands, using rainwater, or storing groundwater. It seems to be compatible.
