Silicon slab: The main raw material of new Class A fire insulation board slab of silicon is silicon dioxide, sulfur oxide, magnesium polystyrene particles, the slurry internally generated by the high-tech closed-cell, made by conservation fire insulation sheet. 1, fire performance good: fire insulation board is an inorganic material (silica, sulfur, magnesium oxide, etc.), fire rating of A-level, the non-burning material, which has good fire resistance. 2, long life, stability: the fire insulation board insulation has good stability and anti-aging properties, can be the same life and architecture. 3, light texture: its density between 80-100kg / m3, can effectively reduce the weight of the building; 4, good sound insulation: sound insulation fire insulation board is 5-8 times that of ordinary partitions can be a good solve the noise problem; 5, high temperature performance: high temperature above 1500 ℃; 6, water resistance: fire insulation board belong thioredoxin magnesium-based material, water resistance is very advantageous. 7, relative strength, and not fragmentation: This product compressive, flexural, strength index were higher, reaching a relatively uniform low-density high strength, use and transport difficult to break, and comply with fire integrity. 8, good environmental performance: non-toxic, non-harmful gas emission impact on the environment caused by the production, construction and use, does not pollute the environment. 9, the construction speed: according to the original foam board construction methods, saving construction time.
