氰聚塑直埋供热管道是天津大学研究成功的一种新型保温防腐管材。并已由天津市建筑塑料制品厂建线生产。它的结构是一种新型复合结构,是在钢管外壁涂敷高效防水防腐化学材料——氰凝作防锈防腐层,然后再裹复聚氨酯硬质泡沫塑料作保温层,再复盖不饱和聚酯玻璃钢作保护层。
The cyano-polyplastics direct-buried heating pipeline is a new type of insulation and corrosion-resistant pipe that Tianjin University has successfully researched. And has been built by the Tianjin Construction Plastic Products Factory. Its structure is a new type of composite structure. It is coated with a highly efficient, water-repellent anti-corrosion chemical material on the outer wall of the steel pipe - cyanide is used as a rust-proof and anti-corrosion layer. Then it is coated with a polyurethane rigid foam as the insulation layer, and then covered with unsaturated poly. Ester fiberglass as a protective layer.
