Quick Introduction of Heat Preservation Material House and Application

Heat insulation material implies material or material composites applied in building containment, thermal gear and impedance heat flow transmission which every single includes heat insulation material and cold insulation material. Heat insulation material  which means lies in that it certainly is always to satisfy heat atmosphere of constructing space or thermal gear in 1 aspect and in 1 other to save power. With each of the international wide variety power becoming each and every day intensified, function of heat insulation material in saving energy added stands out. In line with Japanese power saving practice, it demonstrates that every single and each 1 specific ton heat insulation material utilised, three tons of widespread coal is usually saved per year. The energy saving efficiency is about ten occasions of material production price. Hence, some nations view heat insulation material since the fifth ‘energy' following coal, petroleum, natural gas and nuclear energy.
Heat insulation material home
Firstly, heat insulation material must bear large heat resistance and small heat conductivity coefficient. Secondly, try as far as possible to use organic high polymer material or amorphous inorganic material so as to benefit heat preservation and heat insulation. Thirdly, ensure material proper appearance density. For foam plastic product, the best appearance density is 16 to 40kg/m3 in order to satisfy heat preservation and heat insulation material requirement. Fourthly, material self moisture rate should try to be low. If unavoidable, go with water treatment or coverage by waterproof material on material. Fifthly, heat preservation and heat insulation material should stand against certain impact load and bear same mechanical strength with service surrounding. It should have good adhesive home, small shrinkage rate and atmosphere adapted endurability.
Widespread heat preservation and heat insulation material
Energy saving material applying in constructing external heat preservation and satisfying above properties mainly are polystyrene foam plastic board, glass cotton felt and super light polyphony particle heat insulation slurry and etc. All above various materials have one particular standard characteristic is that there are abundant sealed holes in interior material. Their appearance density is much small which is also necessary for heat preservation and heat insulation material like wall insulation board.
Rock cotton and glass cotton sometimes are generally called mineral cotton. They all belong to inorganic material. Rock cotton doesn't burn and has low cost. It has certain sound insulation effect at the same time of satisfying heat preservation and heat insulation home. But rock cotton quality differs greatly. The better heat preservation home it truly is, the lower density, the lower intension strength and worse endurability it has. Glass cotton has much similarity with rock cotton in residence. But its hand feeling is better than rock cotton which can improve laborer working condition. But it has higher price than rock cotton.
Polystyrene foam plastic is the material taking polystyrene resin considering the main material. It is actually foamed into production by foaming agent whose interior has countless sealed micro-pores. It has small appearance density, small heat conductivity coefficient, low water absorption, good sound insulation house, high mechanical strength, high size precision and even structure. As a result, it has much high occupation rate in exterior wall heat preservation.
Rigid polyurethane foam plastic belongs to a single particular type of rigid foam insulation board  material which has super excellent heat insulation home. Its heat conductivity coefficient is so low that it's incomparable by other materials. Meanwhile, it has unique sealed pore structure which makes it bear superior moisture resistance residence. Getting needless of extra insulation and moisture proof, it simplifies building procedure and lowers constructing price. But as a result of it can be much high priced and easy burning, its application is limited.
Heat preservation technology development can't separate from energy saving material renovation. Creating energy saving must take development of new type power saving material simply because the presumption so as to fully express its function. It's right mainly because energy saving material constant renovation that heat preservation technology superiority day-to-day gets people attention. As a result, we should strengthen new type energy saving material exploitation and usage at the same time of energetically popularizing heat preservation technology so as to truly realize constructing energy conservation.
