大型砼玻璃钢衬里管道,是在定型钢筋砼管内衬以玻璃钢防腐层,用来排除化工企业大流量和腐蚀性废水的下水管道。由于化工废水流量大,现行陶瓷管、塑料管、石棉水泥管等耐腐蚀管材,因管径较小而不能适用,如采用一般钢筋砼管,虽可解决流量问题,但其耐腐蚀能力极差。为此我们采用了玻璃钢衬里技术,并首次在太原化学工业公司水
The large-scale lining of glass-lined steel is a sewer line used for lining glass reinforced plastics in the lining of reinforced concrete pipes, which is used to exclude sewage pipes of large-flow and corrosive wastewater from chemical companies. Due to the large flow of chemical wastewater, the existing corrosion-resistant pipes such as ceramic pipes, plastic pipes, and asbestos cement pipes cannot be applied due to the small pipe diameter. If ordinary reinforced concrete pipes are used, although the flow problem can be solved, their corrosion resistance is extremely poor. . For this purpose, we used FRP lining technology, and for the first time in Taiyuan Chemical Industry Co., Ltd.
