A sound-absorbing and noise-reducing multi-layer sewage pipe

Abstract

The invention provides a sound absorption and noise reduction multi-layer blow-off pipe which comprises a pipe body. The pipe body comprises a PE layer used as a main body. A graphitic layer is arranged inside the PE layer. A hydrophobic anti-corrosion layer is arranged inside the graphitic layer. A fire-proof layer is arranged outside the PE layer. A sound absorption layer is arranged outside the fire-proof layer. A PVDF layer is arranged outside the sound absorption layer. A noise insulation layer is arranged outside the PVDF layer. An anti-oxidation layer is arranged outside the noise insulation layer. According to the blow-off pipe, the multiple layers of structures are compounded, the service life is long, and the sound absorption and noise reduction functions are achieved.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a sound-absorbing and noise-reducing multi-layer 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 (PE)...

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

Moreover, during the discharge of sewage from the pipeline, it will collide with the pipe wall, which will generate a lot of noise, which will bring a lot of discomfort to people's lives. People will be in a noisy environment for a long time, which will also have adverse effects on their health.
