  硅酸鈣絕熱制品保溫材料
Thermal insulation material of calcium silicate insulation products

 
  硅酸鈣絕熱制品保溫材料在80年代曾被公認為塊狀硬質保溫材料中最好的一種,其特點是密度小、耐熱度高,導熱系數低,抗折、抗壓強度較高,收縮率小。但進 入90年代以來,其推廣使用出現了低潮,主要原因表現在90年代初許多廠家采用紙漿纖維,這樣解決了無石棉問題,但由于紙漿纖維不耐高溫,由此影響了保溫 材料的耐高溫性和增加了破碎率;雖然這種保溫材料在低溫部位使用,性能不受影響,但并不經濟。
Calcium silicate insulation products insulation materials in the 80 s, is recognized as the massive rigid insulation materials in one of the best, it is characterized by low density, high heat resistance, low thermal conductivity, high flexural, compressive strength, small shrinkage rate. But enter into the 90 s, its use in the low tide, the main reason for the performance in the early 90 s many manufacturers have adopted the pulp fiber, this solve the problem of asbestos-free, but because of the pulp fibers are high temperature resistant, thus affects the thermal insulation material of high temperature resistance and increase the broken rate; Although this kind of heat preservation material used at low temperature performance is not affected, but not the economy.

 
  纖維質保溫板設備材料
Fiber insulation board equipment material

 
  纖維質保溫材料在80年代初市場上占有較大的份額,是因為其優異的防火性能和保溫性能,主要適用于建筑墻體和屋面的保溫。但由于投資大,所以生產廠家不多,限制了它的推廣使用,因而現階段市場占有率較低。
Fiber insulation materials in the early 80 s occupy the bigger share of the market, because of their excellent fire performance and insulation performance, mainly is suitable for the building wall and roof insulation. But due to the large investment, so the manufacturer is not much, the expansion of the limits its use, and at present the market share is low.
