With the development of the construction industry, the types of wall insulation materials varies differently. Kinds of different wall insulation materials have different functions, and fire resistance are also different, and the disposal of used insulation materials is also different which can be found here.
Plastic Styrofoam is divided into expanded polystyrene, extruded polystyrene, polystyrene resin as the main raw material, the foam-forming agent made of foam, and the interior has numerous closed microporous materials of organic material. High heat preservation and heat insulation performance, processing, construction, maintenance is convenient, widely used, especially the EPS pricebecause of the relatively cheap and have other advantages, it is currently the most widely used. But refractory performance is poor, specification requirements, flammable flame retardant.
Polyurethane rigid foam thermal insulation performance is good, price is relatively high, refractory performance is poor, flame retardant specification requirements, rigid polyurethane plastics foam. More insulation flame retardant foam is B2, namely fuels. Use lighter to burn it may not be burned, but when the big fire, high temperature or continuous function, it can burn quickly and release a large amount of harmful gas.
Organic inorganic composites, for level B1 flame retardant, fire resistant behavior is relatively good. In previous years they are relatively common, it is also cheaper, but because today higher and higher to the requirement of energy conservation, due to its poor thermal insulation performance, to meet the requirements of calculation paste saving energy is very thick, construction is very difficult.
Non-combustible rock wool is very good refractory insulating materials. High hygroscopicity rock wool, however, in the wet state fortress would have dropped sharply, the coefficient of thermal conductivity will increase greatly. Rock wool class of the application of thermal insulation system by abroad abroad is very mature. But rock wool plate internal traction
Low intensity, the amount of soaking water is very high, do not meet the demands of thermal insulation of the external wall, and it is very expensive of imported rock wool board, so it has the best class insulation materials inorganic fireproof performance used very little.
