硬質(zhì)聚氨酯泡沫塑料,為專業(yè)低溫絕熱材料,是以聚醚多元醇與酯為主要原料,輔以阻燃劑、發(fā)泡劑和穩(wěn)定劑等,經(jīng)混合、攪拌產(chǎn)生化學(xué)反應(yīng)而形成發(fā)泡體。閉孔率高,吸水率低。因其為低導(dǎo)熱的閉孔發(fā)泡體,且有一定的阻燃性能,故被用作保冷和低溫范圍的保溫材料。其廣泛應(yīng)用于石油化工、生物制藥、、冷庫(kù)、食品儲(chǔ)藏及家庭用具電冰箱和建筑工業(yè)中隔墻、壁板等行業(yè)的保溫領(lǐng)域。應(yīng)用時(shí),可以由生產(chǎn)廠家預(yù)制成板狀或管殼狀等成品,也可以現(xiàn)場(chǎng)灌注發(fā)泡。
Rigid Polyurethane Foam is a professional cryogenic insulation material. It is mainly made from polyether polyols plus isocyanate added with flame retardant, foaming agent and stabilizing agent and it changes into foaming body through chemical reaction after mixed and stirred. It has high rate of closed cells and low water absorption. As a result, it is usually used as cold insulation and heat preservation at low temperatures. Consequently, it is widely used in industries of petroleum, chemical engineering, ethylene, refrigerated warehouse, food storage, partition wall and wallboard in family refrigerator and architecture industry. It can be prefabricated into slab or pipe, or be foamed on site.
