刚成立两年的聚氨酯喷射技术协会提出了一种新材料,引起了各国的重视,该材料是一种兼有保温和防水两种性能的喷射聚氨酯泡沫。尽管聚氨酯在使用时会产生有害物质,需对操作工人采取保护措施,并对环境造成一定程度的污染,但它却是一种致力于打破传统屋面材料结构的新尝试。可在各种类型的干燥屋面如金属、石棉、水泥、混凝土及防水材料等材料的屋面上进行施工,对那些保温和防水要求较高的工业建筑尤为适用。
The Polyurethane Spraying Technology Association, which has just been established for two years, has proposed a new material that has attracted the attention of various countries. This material is a type of sprayed polyurethane foam with both thermal and waterproof properties. Although polyurethanes produce harmful substances when used, they need to protect workers and cause a degree of environmental pollution, but it is a new attempt to break the structure of traditional roofing materials. It can be applied to roofs of various types of dry roofs such as metal, asbestos, cement, concrete, and waterproof materials, and is particularly suitable for industrial buildings where insulation and waterproof requirements are high.
