Is there any requirement for water in automobile glass manufacturing?

In the production process of automobile glass, we need to clean the dust and oil stains on the glass surface to ensure that the laminated glass is free of any impurities, so as to obtain better adhesion. Washing is an important link in the transparency and yield control of laminated glass process. However, poor water quality will lead to residual substances left in the glass cleaning process, which will affect the adhesion of glass.

 Therefore, in the automotive glass industry, the water requirements are very strict, and most of them will use softened water to solve this problem. Softening water equipment uses a method called ion exchange to remove calcium and magnesium ions in water. When the content of calcium and magnesium ions in the water is high, the ion exchange resin can release sodium ions, and the functional group combines with calcium and magnesium ions, so that the content of calcium and magnesium ions in the water decreases, the hardness of the water decreases, and the hard water becomes soft water.

The glass adhesion is not good, and when impacted by external forces, it is easy to be damaged, affecting the safety of passengers. Therefore, more and more enterprises use softened water equipment to remove impurities in water, improve the quality of glass produced, ensure the yield of laminated glass, and improve the safety factor of automotive glass.
