Fireproof bricks are also called inorganic fireproof bricks. For the convenience of construction, they are prefabricated from inorganic fireproof blocking materials. They are mainly used to build fire-resistant walls in cable trenches in power plants. The construction of fireproof bricks is very convenient and the cost is low. Excellent fire retardant performance. Its external dimensions are the same as those of building bricks, and it does not pollute the environment. So far, it is the most ideal fireproof material used in cable trenches among domestic fireproof building materials.
Fireproof bricks do not have a high market share in the domestic building materials market, and many people do not even know the specific performance of this product
Soundproof fireproof bricks and panels: This was developed in Taiwan in the late 1990s This product was patented in 1999. The product is characterized by: having a glossy layer, a surface layer, an intermediate layer and a bottom layer. The glossy layer is a high-fiber paper coated with glue on the surface; the surface layer is a log sheet; the middle layer is made of bamboo fiber. , wood chips, resin, white charcoal ash and other materials are mixed and pressed; the bottom layer is made of bamboo fiber, wood chips, resin, fine sand and other materials mixed and pressed; and the bottom surface of the brick board is provided with several concave holes recessed toward the inside. A convex strip is provided on the periphery of the bottom opening of the recessed hole. A plurality of silencer holes are recessed on the top wall of the recessed hole, and a bent groove is provided on the bottom surface of the convex strip.
Inorganic block fireproof blocking material Fireproof brick is a non-combustible, water-resistant inorganic fireproof blocking material that can be used outdoors and in environments with accumulated water. This product has excellent water resistance, fire resistance, oil resistance and Corrosive properties, non-toxic, odorless, simple construction method, convenient to replace and pull out cables, suitable for sealing holes where cables pass through floors and walls in electric power, metallurgy, petrochemical, chemical, construction and other industries, and build internal resistance of cable tunnel trenches Fire wall etc. Its technical standard reaches GB8624-1997 and has good flame retardant performance
