Qi Yuanji models the XPS heat preservation board is uses the vacuum to become spongy, the series connected screw rod squeezes out a formation product. Pushes models the board, regardless of from the intensity or from the heat preservation effect and the anti-water vapor seepage and so on various aspects, greatly surpasses gathers ordinary the benzene board. Therefore said that Qi Yuanji models the board is gathers tradition thermal insulation material and so on benzene board best substitute commodities.
present, Qi Yuanji models widely is applied stiffly in the house construction, the bridge capital construction, sound-insulated, domains and so on anti-seepage heat preservation. Its light quality, excel, the heat preservation, the waterproof unique characteristic causes it in the numerous thermal insulation material blooming. Qi Yuanji models the board stable property, the service life reaches 50 year long time, moreover may duplicate uses, therefore Qi Yuanji models the board to be subject to the general customers the favor. Qi Yuanji models the heat preservation board to have the high thermal resistance, the low linear expansion rate's characteristic, its thermal conductivity is lower than other thermal insulation material by far, like EPS board, foaming polyurethane, heat preservation mortar, cement pearlite and so on, because simultaneously this material has the stable chemical properties and the physical structure, thus has guaranteed the material heat preservation performance lasting and the stability. Qi Yuanji models the plate to have the impediment water immersion to enter, characteristics and so on moisture seepage, also has can avoid the material interior because of the condensation, but water, because freezes friendly rises special skill of the crack. Therefore may widely apply in building's foundation and outer wall's heat preservation construction.
