Purpose And Method Of Glass Heat Treatment
Sep 17, 2018

In fact, the glass heat treatment on the tempered glass and tempered homogenization.

Toughening: a method of quenching, somewhat similar to steel, in which the glass is heated to a certain temperature (more than 600 degrees), after being insulated, and then rapidly air-cooled to increase the hardness and strength of the glass;

Homogeneous treatment: after toughened glass strength and hardness is improved, but the internal stress increases, the risk is high, in order to reduce the internal stress of toughened glass, so be homogeneous processing. After toughened glass into homogeneous furnace, heat preservation (temperature lower than tempered a lot of, average more than 200 degrees) a certain time, cool. Is similar to the metal in the tempering heat treatment.
