Process of PET bottle washing line

What is Process of PET bottle washing line?

The scientific name of pet is polyester, which is a crystalline thermoplastic resin. The recovery of waste pet directly affects industrial development. In China, pet plastics are mainly used for manufacturing films, bottles, etc. With the increasing consumption of pet bottles, their recycling is becoming increasingly important.

The quality of recycled pet bottles is affected by two factors: one is sorting, and the other is cleaning and sorting, which is the separation of doped PVC, other polymer bottles, and colored bottles from pet bottles. Many domestic factories use manual sorting, and sorting equipment is relatively popular in Europe and the United States. The general waste pet bottle and chip cleaning line includes a pre washing section, a cleaning section, a rinsing section, and other processes.

The pre washing section: Use water to remove abrasive contaminants from the surface of the material. The water used in this section comes from the cleaning process. Otherwise, this water will be discharged as waste water in the pre washing section. After the pre washing section, the adhesive label glue will begin to melt, and the PVC bottle will begin to fade.

Cleaning part of PET bottle washing machine: residual glue and other pollutants can be separated through cleaning tanks, horizontal separators, and other equipment. During the cleaning process, continuous or intermittent cleaning can be selected based on whether the impurity content of the material is uniform.

PET bottle washing line Rinsing process: It can separate polymers with different densities, clean the material again, and balance the pH value. Under normal circumstances, after such high-quality cleaning, the content of various impurities is controlled at about 10 PPM.
