Second is the first PET plastic bottle waste on non-PET bottle, seat bottom, label and other impurities mechanically separated, then washed, crushed, granulated. Recycled PET shall not contain PVC impurities, otherwise it will affect the color of PET.
Can be separated by artificial means when a relatively small amount when PVC is mixed on a conveyor belt, namely that when the torque effect of PVC and PET plastic bottles have different melting points in different part of the force will be broken by PET and PVC fragments containing a heater and temperature conveyor control, PVC after being melt-adhered on the conveyor belt, so that the PET can be separated.
Tag beverage bottle after bottle broken can be separated with a blower and cyclone combination device removed. Also preclude the separation means separating column by pumping, crushing PET debris from the top of the vertical separation column, debris countercurrent updraft formed using PET label debris difference in specific gravity, the label is removing, PET separator from the bottom up, in order to guarantee label separation efficiency in production may preclude the use of two or more separate devices.
PET washing debris is very important. 80-100 ℃ washed often preclude the use of hot water to soften or dissolve the adhesive labels and the base of EVA adhesive or other types of adhesive, in order to prevent re-adhesion of the adhesive off the PET flakes, the water required additives, e.g. alkali, emulsifiers or other special chemical agents.
Cleaning fluid is generally determined by the factory waste bottle according to the source and the adhesive properties of the composition and the content of their formulations, recycled washing liquid can be filtered off after reheating impurities, in particular cleaning washing tank equipped with a stirrer were, in order to ensure cleaning effect, washing may preclude use secondary washing process.
