plastic pipe extrusion line<\/a> is also constantly improving and improving. During operation, heating, pressing, and shearing are used to transform solid plastic into a uniform and consistent melt, and the production of the melt to the next process involves mixing additives such as color masterbatch, mixing resin, and re crushing. The finished melt must be uniform in concentration and temperature. The pressure must be large enough to extrude the viscous polymer.<\/p>\nThe extruder completes all the above processes through a barrel with a screw and a spiral channel. Plastic particles enter the barrel through a hopper at one end of the barrel and are then transported to the other end of the barrel through the screw. In order to have sufficient pressure, the depth of the thread on the screw decreases as the distance to the hopper increases. External heating and internal heat generated by friction between the plastic and the screw cause the plastic to soften and melt. Generally, different polymers have different applications. Plastic extruders are designed to exhaust outlets, multiple feeding ports, special mixing devices along the screw, cooling and heating of the melt, external heat sources, relative changes in the gap between the screw and the barrel, and the number of screws.<\/p>\n","protected":false},"excerpt":{"rendered":"
