To reduce the self-explosion rate of tempered glass, you can start from many aspects. The following are some specific measures and suggestions: Selection of high-quality glass original: select no stones, impurities, bubbles and other defects of the original glass, these defects are stress concentration points, easy to cause self-explosion. Float glass is preferred because of its better quality and uniformity.

To reduce the self-explosion rate of tempered glass, you can start from many aspects. The following are some specific measures and suggestions:

Selection of high-quality glass original: select no stones, impurities, bubbles and other defects of the original glass, these defects are stress concentration points, easy to cause self-explosion. Float glass is preferred because of its better quality and uniformity.

Improve the production process: homogenization treatment (also known as "hot dip treatment"), by heating to a temperature close to the softening point and holding for a period of time, and then slowly cooling, so that the internal stress of the glass is homogenized and the self-explosion rate is reduced.

Control the degree of tempering to avoid excessive stress and increased risk of self-explosion caused by excessive tempering. Experiments show that when the degree of tempering is increased to a certain extent, the amount of self-explosion will increase.

Improve the quality of edge treatment: optimize the edge treatment process of tempered glass to ensure that the edge is flat and smooth, and avoid the risk of stress concentration and self-explosion at the edge.

Use semi-tempered glass or laminated glass: The self-explosion rate of semi-tempered glass is much lower than that of fully tempered glass, which can be used as an alternative. However, it should be noted that semi-tempered glass needs to be made into laminated glass before it can be used.

The laminated glass is sandwiched between two or more layers of glass with one or more layers of organic polymer intermediate film. When the glass is broken, the fragments will still adhere to the film to reduce damage.

Avoid unfavorable installation and use environment: ensure that the gap between the glass installation is appropriate, and avoid being directly squeezed by the frame.

Keep away from the heat source and the area with large temperature difference to reduce the stress change caused by temperature change. Avoid using sharp objects such as cone-shaped objects to directly hit the glass.

Regular inspection and maintenance: Regularly check the state of the tempered glass. If cracks, bubbles or other abnormalities are found, they should be replaced or repaired in time. Regularly clean and maintain tempered glass to avoid long-term accumulation of dirt and corrosion

Adopt explosion-proof measures: stick an explosion-proof film on the tempered glass, even if the glass is broken, the fragments can be stuck together to reduce damage.

Through the comprehensive application of the above measures, the self-explosion rate of tempered glass can be significantly reduced. At the same time, it should be noted that self-explosion is an inherent characteristic of tempered glass and cannot be completely avoided, but through reasonable design, material selection, production and maintenance, its risk can be minimized.
