Light heat insulation and sound insulation board, also known as foam ceramics, referred to as LC board. It is a closed hole ceramic material with high porosity by using ceramic waste, stone waste, metal tailings, coal gangue, fly ash and other industrial waste as the main raw materials, through powder processing, with other inorganic additives, advanced production technology and foaming technology, calcined at 1200 ℃. The product has small volume density, low thermal conductivity and no radioactive harmful substances. Our company plans to produce heat insulation and sound insulation materials, mainly using stone waste sawing as the main raw material. The foam ceramic wallboard produced by this company has many excellent points, such as heat insulation, sound insulation, fire prevention, heat preservation, high strength, anti-aging, quick freezing, quick freezing, long service life, wide application range and easy assembly.
Compared with the traditional heat insulation and sound insulation materials such as aerated concrete, thermal insulation mortar and organic thermal insulation materials, the product has excellent heat insulation, waterproof, moisture-proof and sound insulation properties, as well as the following incomparable characteristics: first, due to the high temperature calcination, the compressive strength can reach more than 8 MPa, which is far higher than other similar materials, so it has a wider range of application; The second is that the combustion performance reaches A1 level, which has the fire resistance performance of power plant firebrick type, especially suitable for the external thermal insulation system and fire isolation belt with higher fire protection requirements; the third is that it has excellent cold and freezing resistance, with no crack and falling off after soaking in water saturated at minus 15 ~ 20 ℃ for 4 hours, which can meet the building antifreeze requirements in cold areas; Fourthly, it has the advantages of high strength, large area and convenient construction; The five is the superior performance of self insulation and anti-aging. It will not reduce the thermal insulation function due to moisture absorption of thermal insulation materials or other reasons. It overcomes the fatal weakness of other insulation materials, such as aging, short life and fear of open fire, so that the insulation system of the wall can live the same life as buildings and reduce maintenance costs.
