Plastic treatment: the water absorption rate of PC plastic raw materials is large, and it must be preheated and dried before processing. The pure PC should be dried at 120 ℃ and the modified PC should be dried at 110 ℃ for more than 4 hours. The drying time should not exceed 10 hours. Generally, the air extrusion method can be used to judge whether the drying is sufficient. The proportion of recycled materials can reach 20%. In some cases, recycled materials can be used, and the actual amount depends on the quality requirements of the product. The recycled materials should not be mixed with different color masterbatch at the same time, otherwise the properties of the finished product will be seriously damaged.
