What should we pay attention to when connecting PE pipe fittings? First, the pipes and fittings cannot be rotated during the heating and splicing process, they should be inserted in a straight line, and normal welding should form a uniform and firm welding surface on the joint surface. Second, the welding construction should be operated in strict accordance with the technical regulations. The hand-held welding tool is suitable for the final connection of small-diameter pipes and pipeline systems, and the trolley-type welding machine is suitable for the pre-assembled connection of large-diameter pipes. Third, the production of PE pipe adopts general general injection molding machine, the material melting temperature is 200-220 ℃, and the high-speed low-pressure injection molding process is generally used. How to deal with the antistatic situation of PE pipe fittings? First of all, all the components in the formula can be measured according to a certain proportion, mixed in a high-speed mixer, and extruded and granulated by a twin-screw extruder. This process is simple and the processing cost is low. Then, it is also possible to extract and measure all the auxiliary ingredients in the formula according to a certain proportion, add a certain amount of PE carrier, mix by melting and banburying, and extrude and granulate. In addition, the masterbatch can be directly extruded by adding PE resin according to the proportion.
