| 泡沫塑料是以合成树脂为基础制成的，内部具有无数小孔的塑料制品，它具有导热系数低，加工成型等优点，在建筑上刚开始使用。主要用于包装行业（如冰箱）、地下直埋管道保温、冷库保冷。 Foam plastics are made of synthetic resins and have innumerable small holes in the interior. It has the advantages of low thermal conductivity, processing and moulding. It has just begun to be used in construction. Mainly used in packaging industry (such as refrigerators), underground directly buried pipeline insulation, cold storage. 主要产品为聚苯乙烯泡沫塑料和聚氨酯泡沫塑料，但建筑领域应用存在问题。近年来用于钢丝网夹芯板材，彩色钢板复合夹心板材，虽然有一定限制，但发展较快，随着建筑防火对材料要求越来越严格，对该材料应用提出了新课题。 The main products are polystyrene foam plastics and polyurethane foam plastics, but there are some problems in the application of building industry. In recent years, the composite sandwich panel of steel wire mesh and color steel plate has been developed rapidly, although there are some limitations. With the stricter and stricter requirements on materials for building fire prevention, a new subject for the application of this material has been put forward. |
