The production process of PEX pipe: including the pretreatment of raw materials, then the preparation of auxiliary agents, then mixing, melting graft extrusion, then pipe forming, cross-linking, and finally the inspection and packaging of the pipe and the finished product. The function and purpose of PEX pipe additives: The cross-linking agent is to crack the original linear molecular structure to form a graft material, and then form a three-dimensional network structure. The role of antioxidants and color particles is to improve the corrosion resistance of PEX pipes, prevent physical changes from long-term sunlight exposure, and resist long-term ultraviolet erosion, thereby prolonging its service life.
