Basic characteristics:
Light weight, generally 10-96kg/m3, 20kg/m3 Following is the carpet ,24-48 kg/m3 for thehard-,48-96 kg/m3 for the hard boards, including 48 kg/m3 to do theceiling, softening point of 500 ° C About insulation 300 ° C, theUnited States use large, k = 0.9.
Calcium silicate insulation products internally 1970s successfullydeveloped, with high compressive strength, thermal conductivity ofsmall, convenient construction, repeated use of the characteristicsof the power system more widely.
Most of the domestic作坊式生产generally small,one after another from the United States after the introduction offour production lines, advanced technology, the rejection ofinstant-speed fiber-forming, dry Zhenci Zhan, quality, stable,temperature 800-1250 ° C.
Features: acidity derivative 2.0 above,high temperatures, the general chemical pipeline 1000 ° C and more,we must use such materials. Dissolved in 2000 ° C temperaturearound.
Foam is made of synthetic resin-based, with numerous small holeswithin the plastic products, it has low thermal conductivity,forming the processing advantages of the construction has juststarted. Mainly used for packaging industry (such asrefrigerators), buried underground pipe insulation, cold-coldstorage.
Main products are polystyrene foam andpolyurethane foam, but the field of construction problems. Inrecent years sandwich panels for the steel mesh material, colorplate of the sandwich plate, although there are certainrestrictions, but developed quickly, with construction materials onfire safety requirements more stringent application of the materialraised new issues.
Trends: building insulation is energy conservation, improvement ofthe living environment and the use of the function of an importantaspect. Building energy consumption in the whole of mankind in theproportion of energy consumption in general 30-40 per cent, most ofthe energy consumption of heating and air conditioning, buildingenergy conservation is of great significance. As the insulation andpaint diluted with water for the media, non-volatile organicsolvents, not on human and environmental hazards; their productioncosts similar foreign products only about 1 / 5, and as a new typeof insulation Paints, have a good economic efficiency, energyconservation and environmental protection, and insulationeffectiveness and the advantages of simple construction and moreand more people's attention and favor. This space insulation andreflective coatings are experiencing a thermal insulation from theindustrial building insulation to the direction of the main changesfrom thick to thin-layer insulation of technical change, this isthe next major thermal insulation materials One direction. Spacereflective insulation coatings through the application of ceramicball-type particles in the coating material hollow formed in thevacuum chamber floor, and build an effective thermal barrier, notonly its own thermal resistance, low thermal conductivity, andheat-reflective high rate, reducing buildings to the sun Theabsorption of heat radiation, lower coating the surface temperatureand internal space, so it has been recognized as experts in linewith the development prospects of efficient energy-savingmaterials.
