Insulating glass desiccant filling machine, use and precautions of desiccant
Desiccant plays an important role in the sealing process of insulating glass, which can be divided into three points:
1. It can absorb the moisture in the air layer during the production and sealing of insulating glass.
2. Adsorption of volatile organic solvents
3. Adsorb the water vapor that the hollow glass window enters into the air layer every day. At the same time, it is also required that the desiccant does not adsorb the air or inert gas in the air layer. Therefore, the best choice in the production process of insulating glass is 3A molecular sieve.
Use and Precautions of Desiccant in Insulating glass desiccant filling machine
Desiccant plays an important role in the sealing process of insulating glass, which can be divided into three points:

2. Adsorption of volatile organic solvents
3. Adsorb the water vapor that the hollow glass window enters into the air layer every day. At the same time, it is also required that the desiccant does not adsorb the air or inert gas in the air layer. Therefore, the best choice in the production process of insulating glass is 3A molecular sieve.
The radius of water molecules is smaller than the pore size of 3A molecular sieves and can be adsorbed by 3A molecular sieves, while the molecular radius of oxygen, nitrogen and other gases is larger than the pore size of 3A molecular sieves and cannot be adsorbed by 3A molecular sieves. Therefore, although there are many kinds of molecular sieves, according to the requirements of desiccant for insulating glass manufacturing, only 3A molecular sieves are the most suitable for insulating glass.
When choosing molecular sieves, you should pay attention to:
1. When choosing, first choose products produced by regular manufacturers. When purchasing, you should look at the quality inspection standards and inspection reports presented by the manufacturers.
2. Take some granules and place them in your hands, and drop a few drops of water to make the surface of the granules moist and feel hot. This is because the water displaces the heat generated in the pores of the molecular sieve during activation, and the heat is proportional to the size of the pores.
3. Gently rub the granules with water with your fingers, no powder is produced.
4. Observe whether the particle surface is uniform and smooth.
Because molecular sieves have strong adsorption capacity and water absorption rate, they should also pay attention to moisture-proof during use, especially when filling in rainy days with high air humidity, the operation must be quickly loaded and sealed. When pouring molecular sieve into the aluminum spacer, it must be filled completely, and at the same time, more than 90% of the air holes of the aluminum spacer must have good ventilation, otherwise the expected effect will not be achieved.
