Quick Introduction of Heat Preservation Material Property and Application

Heat insulation material implies material or material composites applied in building containment, thermal gear and impedance heat flow transmission which every involves heat insulation material and cold insulation material. Heat insulation material which implies lies in that it truly should be to satisfy heat atmosphere of developing space or thermal gear in 1 aspect and in one other to save power. With all the international selection power becoming just about every day intensified, function of heat insulation material in saving energy further stands out. In line with Japanese energy saving practice, it demonstrates that every single and just about every one particular unique ton heat insulation material utilised, three tons of popular coal is usually saved per year. The energy saving efficiency is about ten occasions of material production value. Therefore, some nations view heat insulation material given that 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. Prevalent heat preservation and heat insulation material Power saving material applying in building 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 a single particular typical 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 price. 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 that 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 one particular distinct 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 particular sealed pore structure which makes it bear superior moisture resistance property. Getting needless of extra insulation and moisture proof, it simplifies building procedure and lowers developing cost. But because it can be much high priced and easy burning, its application is limited. Heat preservation technology development can't separate from power saving material renovation. Constructing power saving must take development of new type power saving material simply because the presumption so as to fully express its function. It's right given that 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 definitely realize developing energy conservation.
