Glass mold is an industry problem in the glass industry, in the spring and summer of each year, due to the weather characteristics of high temperature and humidity, the mold of glass enters the peak period, therefore, how to do a good job in glass mildew prevention work has become the primary task of many glass enterprises.
Causes of mold in glass.
The glass used in daily life is mostly made of quartz sand (SiO2), soda ash (Na2CO3), limestone (CaCO3) and feldspar as the main raw materials, among which SiO2 (content about 72), Na2O (content about 15) and CAO (content about 9), so it is called soda-lime glass, which is widely used because of its low cost.
According to research, during the annealing process of soda-lime glass, alkali ions will move to the glass surface, making it easy to carry out ion exchange on the glass surface; For example, vitreous SiO2 on a surface can be hydrolyzed.
Therefore, when soda-lime glass is stored in a humid environment, water or moisture will be adsorbed on the surface of the glass, gradually diffuse into the glass, when the soluble sodium silicate (Na2SiO3) in the surface layer is hydrolyzed, and then come into contact with the carbonic acid (H2CO3) formed by water (H2O) and carbon dioxide (CO2), it will produce orthosilicic acid (H4SiO4), which is weaker acidic than carbonic acid, if the saturated orthosilicic acid (H4SiO4) solution is placed for a long time, There will be amorphous silica (SiO2) precipitates, which are milky white in color and appear as colloidal particles, precipitates or gels.
Glass anti-mold paper is a commonly used means now, and the anti-mildew effect is very good, and it is not very expensive.

Do you still need PE paper now?
-
It's all nonsense upstairs, glass PE paper is a polymer material with organic fibers, which is better than ordinary Oh, I hope it can help you.

I don't know the specifics. The difference is that the raw materials are different, and the performance is different.

Glass mold paper can indeed prevent glass mildew, of course, it can also play a role in glass isolation, to prevent glass scratches, but its disadvantages are also many, for a long time, there will be paper prints, the glass is ugly, and there are many people will use this ** paper, because there are a lot of dirty things and some particles on it, which can easily lead to glass pollution and scratches, if you are used on glass, it is best to consider using glass mold powder and other products, at present, large domestic glass companies have switched to this.
-
The main use is of course on glass.
In fact, it is said to be anti-mold paper, but it does not play the role of anti-mold, for glass, his role is isolation!
-
There are two functions, one is to absorb the moisture between the glass, to prevent the glass from moisture and mildew, and the other is to prevent the friction between the glass and cause injury.

Hello! At present, there is no common standard for such products, and the local quality supervision bureaus are different.
And the inspection standards of automobiles are even rarer. It is advisable to consult the local quality inspection department.

There is a possibility of mildew! The principle of preventing glass mildew is to adsorb away the moisture attached to the glass surface and prevent glass mildew.
Float glass (original tempered glass) has one side of the air surface and the other side of the tin surface during production, and the oxidation of the tin surface in a specific environment of humidity, high temperature and airtightness produces glass mildew;
The clamp between the glass and the glass is mainly in the dry environment to absorb moisture and water vapor in the air, if the mold paper adsorption saturation or rain and water, etc., it will cause a very humid environment for the glass, if the ambient temperature reaches 35-40 degrees, the glass will mildew in about 10 days1
