Technical Field

Background
The PE material is widely applied to the field of water supply pipe manufacturing due to the characteristics of high strength, corrosion resistance, no toxicity and the like. Because it does not rust, it is an ideal pipe material for replacing general iron water supply pipe. Another reason why polyethylene can be used is that polyvinyl chloride is increasingly under pressure from the environmental point of view. Firstly, the hygiene properties of polyvinyl chloride itself are a problem: it is known that the production of polyvinyl chloride pipes, under regular production and strict control, allows to guarantee hygienic performances, allowing applications in the field of drinking water. There is concern that problems may occur in poorly controlled places: if the content of vinyl chloride monomer in polyvinyl chloride resin exceeds the standard, toxic auxiliary agents are misused in the formula of the polyvinyl chloride pipe for water supply. Water supply pipes and pipe fittings and the like are mistakenly used for the polyvinyl chloride pipes and pipe fittings for drainage which are not guaranteed to be nontoxic. Secondly, the problem of recycling the polyvinyl chloride pipe is as follows: polyvinyl chloride is thermoplastic plastic like polyethylene and can be used theoretically, but the proportion of old plastic products which can be recycled is limited, the main treatment mode is incineration for recycling energy, polyvinyl chloride contains chlorine, harmful substances can be generated when the control is not good during incineration, and polyethylene only contains carbon hydrogen and generates water and carbon dioxide after incineration. The flexibility of polyethylene pipe systems has great technical and economic value. The flexibility of polyethylene is an important property, which greatly increases the value of the material for pipeline engineering.
However, the existing PE water supply pipe has low corrosion resistance, is easy to rot and electrochemically corrode under the corrosive media of acid, alkali, oil and the like, greatly prolongs the service life of the PE pipe, and limits the application range of the PE pipe. Therefore, it is necessary to develop a corrosion-resistant PE water supply pipe material to solve the above problems.
