Raw materials can be plasticized in plastic extruder

According to the formulation requirements of the plastic products, the uniformly mixed raw materials are fed into the barrel of the plastic granulator through the hopper. As the screw rotates, the material is forced by the threads toward the front of the barrel. Due to the resistance of the filter, the manifold and the forming tool at the front end of the barrel, and the gradual reduction of the volume between the threads (equal thread, the thread depth becomes shallower and the material is heated by the barrel, the result is pushed by the thread The advancing raw materials are subjected to the conditions of extrusion, shearing, heating and stirring, and the friction between the raw materials, the raw materials and the inner wall of the barrel and the thread surface generates a certain amount of heat, so that the temperature of the raw materials is gradually increased while moving forward. The physical state also gradually changes from a glassy state to a high-elastic state, and finally becomes a viscous flow state, achieving complete plasticization. Since the screw has been continuously rotating continuously, the plasticized uniform melt is isostatically pressed and formed. Extrusion of the die mouth into a plastic product with a certain shape. After cooling and shaping, the extrusion molding of the product is completed. The invention of the waste plastic granulator is the gospel of mankind, but it is smoked by some unscrupulous owners. Heart, through the improper and improper means to seek the profits of recycled plastics, not only the recycled plastic is not qualified, the processing is rough, and there is no disinfection process. Low seed production workshop price of the product, so it is a lot of buy used, so far no effective way to put an end to prohibition.
