Why choose tempered glass 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? Can plastic be used?
belowZhongnuo TestingLet me explain to everyone.
In GB3836.1-2010, section 26.5.2 specifies the temperature thermal shock test for transparent components,The purpose is to verify the thermal stability of glass under rapid cooling conditions. At present, tempered glass is a material that can meet this requirement and has a relatively high cost-effectiveness.
Popularize, tempered glassDue to quenching after heating, a uniform and permanent compressive stress layer is formed on the surface to counteract the tensile stress generated on the surface during rapid cooling. Therefore,Even if qualified tempered glass is subjected to stress caused by rapid cooling, there will still be compressive stress to counteract its effect.
