Perlite fireproof (door core) plate specifications:
300 x 500 x (20, 30, 40, 50, 60, 80, 100, 120 ) mm; or designed according to customer requirements, more than 17 thickness can be used for pattern.
According to GB8624-1997 "Classification Method of Combustion Performance of Building Materials" by the National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center: continuous burning time Os, the mass loss rate is only perlite fireproof board is made of expanded perlite powder plus high temperature fireproof sticky The mixture is pressed by a mold and is suitable for filling materials of wooden fire doors and steel fire doors. It is an alternative product of aluminum silicate cotton and rock wool. With a bulk density of (260-300g/m3), high refractoriness (>1100°C), high compressive strength (0.9-2.OMPa), low thermal conductivity (≤0.051 W/MK), non-combustible, non-toxic, odorless, No pollution, etc., the combustion performance reached A grade by the National Building Materials Testing Center. The fireproof and heat insulation performance is higher than that of aluminum silicate cotton and rock wool. It is a new type of fire door filling material with low cost, excellent fireproof performance and environmental protection performance.
