长期以来,因为很难找到一种经济实用长效的防水绝热材料,使房屋屋面防水一直成为围绕人们的一个难题。随着材料、石油化工科学技术水平的不断发展,一批合成新材料出现,给我们展示了美好的前程和希望。 不久前青岛金北洋工程材料有限公司研究所的专家们终于研制出了“沥青聚氨酯硬质泡沫塑料”。为管道防腐保温、保冷和屋面防水绝热提供了一种经济、实惠、长效的新型材料。 该材料具有质量轻、强度高、导热系数低、闭孔
For a long time, because it is difficult to find a long-lasting economic and practical waterproof insulation materials, waterproof roofing has become a problem around people. With the continuous development of materials and petrochemical science and technology, a batch of synthetic new materials appear, showing us a bright future and hope. Not long ago, Qingdao Golden Northern Engineering Materials Co., Ltd. Institute of experts finally developed a “rigid polyurethane foam polyurethane.” For the pipeline anti-corrosion insulation, cold and roof waterproof insulation provides an economical, affordable, long-lasting new material. The material has light weight, high strength, low thermal conductivity, closed-cell
