Product Introduction
The twin-screw extrusion granulating unit transports solid melt polymer and extrudes it through a process of shearing and mixing at a certain temperature. This includes the phase changes, mixing forms, and structural changes of the polymer and materials during the extrusion process, as well as the relationship between the mixture and its properties.
Working Principle
The material passes through the feeding port and, under the action of the rotating screw, is rolled into a ball and advances along the screw grooves. Due to the shearing, compressing, and mixing action of the screw, the material undergoes further blending and plasticization. The temperature and pressure gradually increase, presenting a viscoelastic state, and then passes through the die at a certain pressure and temperature, finally forming the desired shape of the product.
