Pet bottle flake recycling cleaning production line process
PET scientific name polyester is a crystalline thermoplastic resin. The recycling of waste pets directly affects industrial development. In China, pet plastic is mainly used to make films, bottles, etc. With the increasing consumption of pet bottles, their recycling work is also increasingly important. The quality of the recycling of pet bottles is affected by two factors: one is sorting, and the other is cleaning and sorting, which is to separate the PVC doped in pet bottles, other polymer bottles and colored bottles. Many domestic factories use manual sorting. In Europe and America, sorting equipment is more popular. Waste general pet bottle chip cleaning line includes pre-washing part, cleaning part, rinsing part, etc. Pre-washing part: use water to remove contaminants with abrasive effect on the surface of the material. The water used in this part comes from the cleaning link, otherwise these water will be After the waste water is discharged in the pre-washing part, the adhesive label glue begins to melt, and the PVC bottle begins to fade. The cleaning part of pet bottle flakes: the residual glue and other contaminants can be separated through the cleaning tank, horizontal separator and other equipment. During the cleaning process, continuous or intermittent cleaning can be selected according to whether the impurity content of the material is uniform. Rinsing process: It is possible to separate polymers with different densities and to clean the substances again and balance the PH value. Under normal circumstances, after such high-quality cleaning, the content of various impurities is controlled at about 10PPM.
