Background
After plastics are added into a machine barrel of an extruder from a hopper, the plastics are forcibly pushed to the direction of a machine head by threads along with the rotation of a screw rod, and the volume between the threads is gradually reduced, so that the advancing materials are subjected to great pressure and are heated by a heat source of the machine barrel; in addition, when the plastic is subjected to forces such as compression, shearing, and stirring during movement, a large amount of heat is generated by friction with the cylinder, the screw, and the plastic molecules. The plastic in the cylinder is heated continuously, the physical state of the plastic is gradually changed from a glass state to a high elastic state and finally to a viscous state, so that the plastic is completely plasticized; because the screw rod is always rotated stably, the plasticized material is extruded from the die opening of the machine head in equal pressure and equal quantity to form a plastic product with a certain shape, and the plastic product is cooled and shaped to complete the extrusion molding work.
Generally, a screw extruder is used for processing, mixing and extruding, and then pelletizing or molding, and since polyethylene is particularly sensitive to the temperature of an extruder barrel during mixing and extruding, the extruded melt is greatly influenced by too high or too low temperature.
