The so-called glass self-explosion refers to the self-explosion of glass under the action of no direct external force. It occurs during tempering or preservation, which is a characteristic of tempered glass. So how did he happen? How to prevent it?
The tempered glass self-explosion has the following reasons:
1. The inherent quality of glass is not good, such as: stones, crystals and bubbles.
2. The defects such as scratches, gaps, blasts, and blasts generated during the transportation or processing of glass are likely to cause stress concentration.
3. The tempered glass is uneven and asymmetrical during heating and cooling, and it is easy to cause uneven stress distribution.
4. The greater the glass tempering stress, the higher the degree of glass tempering, and the tempering self-explosion rate also increases.
All of the above are common phenomena.
For the above reasons, the following points should be noted during the production operation:
1. Carefully check the intrinsic quality and external quality of the glass, and find that the defective glass is firmly in the furnace.
2. During the heating process of the glass, the temperature difference between the upper and lower parts should not be too large; when cooling, the upper and lower wind pressures should be balanced as much as possible.
3. During the operation, it is important to make the tempered glass at a better tempering temperature, a better tempering time and a better wind pressure. It is important not to make the tempering degree of the glass too high.
