company news about What is the advantage of light refractory brick

Light refractory brick commonly known as foaming turn, at present for interior wall tile, he is not true and false floor load, at the same time the sound insulation effect is also very good, the strength is a selection of high-quality tabular corundum or mullite as aggregate, and then to Shi Fuhe as a matrix of silicon wire. In addition, add special additives and a small amount of rare earth oxide mixing, high-pressure molding. High temperature sintering. Light refractory brick light texture, green environmental protection. In dry conditions, the capacity is 500-700kg/m*3, same volume, it is the 1/4 concrete, clay hollow brick 1/3, 1/2; and any pollution phenomenon does not exist in the process of manufacturing and transportation. In the process of producing lightweight brick will be formed within the tiny pores, can effectively absorb and volume is part of heat, makes his heat insulation performance is five to ten times the ordinary bricks. At the same time that can absorb a certain decibel noise, provide a quiet and comfortable living environment for residents. Stomatal structure makes the capillary effect is poor, water absorbing moisture slowly, with the same volume of water to the time required for saturation is five times more than ordinary bricks, and lightweight refractory brick by quality of river sand and coal powder as the siliceous material, its contraction values. To ensure that the wall cracking phenomenon does not occur because of heat expansion and cold contraction.
