PE is the English abbreviation of polyethylene, and the application range of the common PE pipe water supply pipeline is the temperature lower than 40 ℃, so that the PE pipe water supply pipeline cannot be used for a hot water conveying pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the micro-thin section is semitransparent to a certain degree. PE has excellent resistance to most domestic and industrial chemicals. Certain classes of chemicals cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The plastic pipeline in China develops rapidly and the quality is improved continuously. Plastic pipe industries mainly including polyvinyl chloride (PVC-U) pipes, Polyethylene (PE) pipes, and polypropylene (PP-R) pipes have been primarily formed. Among them, Polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas distribution, gas transmission pipes, electrical and telecommunication protective sleeves, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly applied to urban water supply, urban gas supply and farmland irrigation. The nanometer antibacterial PE pipe is prepared by adding nanometer antibacterial masterbatch into inner layer plastic of the pipe and extruding the mixture to obtain the pipe with antibacterial, sanitary and self-cleaning effects. The method is mainly applied to urban water supply pipe networks, irrigation diversion projects and agricultural irrigation projects. Because the pipeline connection adopts a hot melting and electric melting connection mode, the integration of the interface and the pipe is realized, and the one-directional stress and the axial impact stress generated by the internal pressure can be effectively resisted. And in addition, a heavy metal salt stabilizer is not added in the production process, the material is non-toxic, does not scale, does not breed bacteria, and avoids secondary pollution of drinking water.
