聚氨酯涂膜防水材料是北京市建筑工程研究所研制、北京市椿树橡胶制品厂生产的一种新型防水材料,它富有弹性,施工方便,防水效果好。我公司在在中国银行金融大楼的屋面、厨房、厕所、卫生间采用了聚氨酯涂膜防水新工艺,实践证明防水效果良好。聚氨酯涂膜防水材料可取代石油沥青油毡做建筑防水,克服了传统做法的低温脆裂、高温流淌,容易产生起鼓、老化、龟裂、腐烂、渗漏等质量通病。一、聚氨酯涂膜防水施工 1.防水基层按设计要求用1:3水泥砂浆找坡抹平压光,不得有凹凸不平、松动起砂
Polyurethane coating waterproof material is a new type of waterproof material developed by Beijing Construction Engineering Research Institute and Beijing Yushu Rubber Products Factory. It is flexible, easy to construct and has good waterproof effect. Our company adopted a new waterproof technology for polyurethane coating film on the roof, kitchen, toilets and toilets of the Bank of China’s financial building. The practice has proved that the waterproof effect is good. Polyurethane film waterproof material can replace petroleum bitumen tar felt for building waterproofing, overcome the low temperature brittleness and high temperature flow of traditional methods, and it is prone to produce common defects such as drums, aging, cracking, rot and leakage. First, polyurethane coating waterproof construction 1. Waterproof base layer according to the design requirements with 1:3 cement mortar to find the slope leveling, no uneven, loose sand
