最近,长春市建材化工实验厂研制成功两种建筑用高效防水材料——聚氨脂塑合防水材料和聚氨脂涂膜防水材料。这两种防水材料可用于屋面、地下防水、管道堵漏、地面加固和金属物的防腐,可冷涂和热涂结合使用,既能适应严寒的北方,也能适应高温的南方。(文一) Recently, Changchun City Building Materials Chemical Experiment Factory has successfully developed two types of high-performance waterproof materials for construction: polyurethane plastic waterproof material and polyurethane film waterproof material. These two kinds of waterproof materials can be used for roofing, underground waterproofing, pipeline plugging, ground reinforcement and metal anticorrosion. They can be used in combination with cold coating and hot coating. They can not only adapt to the cold in the north, but also adapt to the high temperature in the south. (Text 1)
