参加第三次防水密封材料技术交流会的单位有105个,126名代表。有12个单位带来了产品样品和图片、幻灯片。会议交流资料44篇。从会上可以看出,我国防水材料有了新进展。防水密封膏以溶剂型为主,在生产工艺和施工机具方面有了新的改进。防水片材发展很快,质量优良的三元乙丙橡胶已在防水要求严格的工程上应用;氯化聚乙烯防水卷材也已在工程中应用:自粘型防水片材也在试制研究,已取得可喜的进
There were 105 and 126 representatives participating in the third technical seminar for waterproofing and sealing materials. There are 12 units brought product samples and pictures, slides. 44 meetings and exchanges of information. From the meeting, we can see that there has been new progress in our waterproof material. The waterproof sealant is based on a solvent type, and new improvements have been made in the production process and construction equipment. Waterproof sheets have developed rapidly, and the excellent quality of EPDM rubber has been applied in projects requiring strict waterproofing; chlorinated polyethylene waterproofing membranes have also been applied in the project: Self-adhesive waterproof sheets are also in trial production. Has made gratifying progress
