Discussion on the function of special fireproof glass!

  Special fire-proof glass is a glass substrate with special components, generally including borosilicate glass, aluminosilicate fire-proof glass and glass-ceramic fire-proof glass
Its common feature is low coefficient of thermal expansion; Due to different processing components, the softening point of glass is high (above 9000 ℃), and the glass with low coefficient of thermal expansion will not burst and deform due to high temperature under strong flame The expansion of nickel sulfide inside the special glass is the main reason for the self explosion of the glass
After toughening, the glass will form compressive stress in the surface layer, and the inner core layer presents tensile stress
The compressive stress and tensile stress form a balance; Glass itself is a brittle material, which is resistant to pressure but not tensile, so most of the breaking of glass is caused by tensile stress; Special glass not only has fire resistance, but also has outstanding strength and high hardness
The compressive strength can reach more than 125mpa, which is 4-5 times larger than ordinary glass, and the impact strength can also be increased by 4-5 times
Once broken, the glass can form many obtuse small particles, which can avoid injury to people and objects
Its stable working temperature is 288 ℃, and can withstand the change of temperature difference of 204 ℃, Therefore, this glass has good mechanical properties and thermal stability Fireproof glass http://www
