简体中文In the extrusion process of recycled particles, if you want to improve the homogeneity of the particles and ensure the production of high-quality products, you need to optimize the mixing effect of the screw. The mixing effect of the screw is related to many factors. The first is the design of the screw, including the screw Pitch, thread depth, as well as the structure and shape of the screw, reasonable screw structure design can ensure that the plastic is fully mixed and dispersed during the screw movement.
The adjustment of operating parameters also has a direct impact on the mixing effect. Parameters such as screw speed, feed speed and temperature control of the extruder need to be set appropriately according to the specific plastic type and the requirements of the recycled particles. Too high or too low screw speed may lead to poor mixing effect, so it is necessary to adjust the speed to optimize the mixing effect. Adjustment of the feed speed can affect the residence time of the plastic and thus the mixing effect. Temperature control is of great significance to the fluidity and mixing properties of plastics, and reasonable temperature adjustment is required based on the melting characteristics of different plastics.
Additionally, different mixing strategies are required for different types of plastics. For example, for high-viscosity plastics, more intense mixing may be required, such as increasing the number of mixing sections or increasing the screw mixing effect of the mixing section. For plastic raw materials with different particle sizes, appropriate adjustments need to be made according to the actual situation to ensure uniform mixing.
