Product Desciption

The processing of plastic raw materials is mainly the melting, flowing, and cooling of the rubber pellets into finished products. It is a process of heating and then cooling, and also the process of changing plastics from particles to different shapes. The following will explain the processing at different stages. process. 1. Melting The device heater (Heater) allows the raw material particles to gradually melt into a fluid flow, which is mainly suitable for temperature adjustment of different raw materials. Increasing the temperature will tend to accelerate the flow of the raw materials, which may increase the efficiency but may not ensure the yield, and must be suitable. Balance. Another good effect and PP polypropylene high thermal cracking characteristics, it is best to make the raw material smooth and smooth to the die during production to avoid the lack of filling or reflow phenomenon, the reflow represents the flow of raw materials faster than the output rate, and finally The increase in the average flow efficiency is equal to the increase in MFR, which is one of the methods available for processing, but it also causes the abnormality of the MFR distribution to cause an increase in instability, which may lead to an increase in the defect rate. However, the PP polypropylene finished product is not a product with high dimensional precision because of the application relationship, so the impact is not great. 2, screw Most of the PP polypropylene processing relies on the screw to drive the fluidity, so the screw design has a great influence. The diameter of the screw affects the output. The compression ratio affects the pressure value and also affects the output and finished product. This also includes a variety of materials. The mixing effect of (color masterbatch, additive and modifier). The flow of raw materials mainly depends on the warmer, but the friction of the raw materials will also generate frictional heat to promote the fluidity. Therefore, the screw compression is smaller than the small-driven flow, and the rotational speed must be increas
