Problems solved by technology

[0003] Existing PE pipes are not satisfactory in terms of wear resistance and compression resistance. Granulation equipment is often used in the preparation of PE pipes. The existing granulation equipment cannot meet the qualified material uniformity before granulation, and in The lack of sufficient stirring before granulation makes the quality of material granulation poor; the existing granulation equipment cannot ensure that the material maintains a stable temperature, so that the material is partially cooled before granulation, which affects the quality of granulation; Some granulation equipment has the problem of waste when stirring, and it will affect the stirring efficiency

Description

technical field [0001] The invention relates to the technical field of gas pipe preparation, in particular to a reinforced wear-resistant PE gas pipe and a preparation method thereof. Background technique [0002] Plastic pipes are currently developing steadily, and PE pipes, PP-R pipes, and UPVC pipes all occupy a place, among which the strong development momentum of PE pipes is the most eye-catching. PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Vinyl. When processing different types of PE pipes, according to different application conditions, the requirements for extruders an...
