为了满足我国室内装饰材料发展的需要,北京市建筑塑料制品厂在同济大学的协助下,建成了一条“多层复合弹性塑料地板”中间试验线。多层复合弹性塑料地板是以悬浮法聚氯乙烯树脂为主要原料、玻璃纤维布为底衬,采用压延、复合、发泡、化学压花等工艺,选材适 In order to meet the needs of the development of China’s interior decoration materials, Beijing Construction Plastics Factory, with the assistance of Tongji University, built a “multilayer composite elastic plastic floor” intermediate test line. The multi-layer composite elastic plastic floor is based on the suspension method of polyvinyl chloride resin as the main raw material, glass fiber cloth as the substrate, and uses calendering, compounding, foaming, chemical embossing, etc.
