Common problems and treatment methods of toughened Glass
In the process of processing toughened glass, various parameters are unreasonable, which may cause toughened glass bending and other appearance quality. In this paper, some common bending reasons and how to solve the quality problems of toughened glass are summarized.
1. Upwarping: reason: when the glass comes out of the furnace, the upper surface temperature of the glass is higher than the lower surface temperature, the upper surface temperature of the glass is too high, the lower surface temperature is low, and the upper wind pressure is lower than the lower wind pressure.
The solution is to increase the bottom temperature of the furnace and reduce the upper temperature properly. If the furnace temperature is stable, the air gate pressure can be adjusted, and the upper pressure is greater than the lower pressure when the height of the nozzle is constant.
