Why should tempered glass be used for explosion-proof transparent parts?

Transparent parts are a very important material for explosion-proof electrical equipment. When choosing transparent parts, customers always ask what material to use? Can glass be used? Is plastic okay?

belowZhongnuo TestingLet me explain to everyone.

In GB3836.1-2010 Section 26.5.2, there is a clear provision for the temperature thermal shock test on transparent components,Its purpose is to verify the thermal stability of glass under rapid cooling conditions. Currently, tempered glass is a material that can meet this requirement and has a relatively high cost performance ratio.

Popularize it, tempered glassDue to quenching after heating, a uniform and permanent compressive stress layer is formed on the surface to counteract the tensile stress generated during rapid cooling. Therefore,Even under the stress generated by rapid cooling, qualified tempered glass will have compressive stress to counteract its effect.
