Monolithic fireproof glass (dfb) is made of ordinary sodium calcium silicon float glass as raw material for deep processing made of “deep tempered” glass. the surface pressure should be much higher than that of ordinary glass, generally above 150mpa, and the surface of the same thickness of the ordinary tempered glass compressive stress between 90-110mpa. fire-resistant glass chip only has fire integrity, no insulation nor thermal radiation, belongs to the class c fireproof glass. syp monolithic cesiumic glass has the advantages of fire resistance: flameproof glass according to the performance of fire belongs to c fireproof glass, meet fire integrity requirements. safety: broken split into small particles obtuse not easy to hurt. Strength: flameproof glass strength is higher than the strength of tempered glass. Thermal stability: monolithic fire-resistant glass with higher than tempered glass withstand temperature change ability. Machinability: it can also be made of composite processed glass products by means of coating, hollow and interlayer.
