Information
  PVC plastic granules are recyclable, and they are gradually developing. At the same time, they also promote the understanding of plastic materials. There is also PET here. When these two plastics are mixed together, we will How do you separate them?
  One of the methods for separating PVC particles and PET is the floating drop method, also known as wet separation. Because the difference in separation density between PVC plastic and PET is relatively small, the difference between hydrophobicity and hydrophilicity is used to separate the two, and the pulverized waste plastic is treated with a specific medicine to adjust the wetting time, concentration, temperature and The pH value, etc., can change the water wettability of the plastic. The waste plastic is bubbled in the floating cylinder, the bubbles adhere to the hydrophobic plastic particles to float, and then the flocculant is used to collect the floating waste plastic, so that Separate the two.
  There are more than one way to separate PVC and PET, and we can also use X-ray analysis. Because PVC plastic contains about 50% chlorine, X-ray is mainly used to detect chlorine, so we can separate PVC and PET more easily and conveniently by X-ray.
