A corrosion-resistant and anti-blocking PE composite sewage pipe

Abstract

The invention provides an anti-corrosion anti-blocking PE composite pollution discharge pipe which comprises a pipe body. The pipe body comprises a PE layer serving as a main body, a graphite layer is arranged in the PE layer, a hydrophobic anti-corrosion layer is arranged in the graphite layer, a reinforcing layer is disposed on the outer side of the PE layer, a PVDF layer is arranged outside the reinforcing layer, and an anti-abrasion layer is arranged on the outer side of the PVDF layer. According to the anti-corrosion anti-blocking PE composite pollution discharge pipe, multiple layers of structures are combined, and the anti-corrosion anti-blocking PE composite pollution discharge pipe is long in service life.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a corrosion-resistant and anti-blocking PE composite sewage discharge pipe. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. Plastic pipes are an important branch of many chemical building materials. From the perspective of different classifications of chemical materials, plastic pipes can be divided into polyethylene ...

Problems solved by technology

[0004] Compared with the drainage pipe, the sewage pipe has higher requirements on the pipeline. Compared with the water quality of the ordinary drainage pipe, the sewage discharged from the sewage pipe is more polluted. The sewage discharged from the sewage pipe often includes a large amount of Solid particles such as mud and dirt, these solid particles have been rubbed against the pipe wall for a long time, making the pipe wall thinner and rougher, causing pipe blockage or water leakage, and the sewage even contains some strong corrosive chemicals, which are harmful to the pipe wall. The damage is very serious, so, combined, will seriously affect the service life of the pipeline
