Identification method of plastic PET recycled material

Identification method of plastic PET recycled material：

1. Smell the smell first, the smell of the PET hook is different from ordinary plastic. Burn it with a lighter, and then you will smell a very aromatic and comfortable smell (burn a bottle to smell it), if the PET contains other ingredients, the smell is very pungent nose. There is a bottle that contains SEBS ingredients that can't be used.

2. If the burning part is too dark or the oil drops very quickly, most of the melting points are abnormal, which is often found in PET film.

3. Wire drawing, when burning, pull the wire on the lighter to see if the wire is long, then break the pulled wire, and check the breakpoint in the middle to see if the wire is rolled into a small circle, and the longer the roll is. More indicating a high melting point. But generally if it is a bottle tablet, it should not be a big problem. The most critical point is to distinguish whether it contains PVC, which is the fatal injury of PET. First take more samples, then lay flat in a sunny place, the PVC is light blue in the sun. If you fold in half, there will be white creases. The above is the naked eye identification, the accuracy is limited, mainly depends on experience. There is also a more practical and better way. Buy an oven and adjust the temperature to 250 degrees and bake there for half an hour. If the goods contain PVC, there will be a lot of yellow spots on the surface; if the melting point is not enough, it will be very fast. melt. In fact, there are many varieties of PET, such as PET shredded films from foreign factories, pulp blocks, and rolled films with a length of less than 30 cm, all of which have different customer groups. The identification of these goods is strongly required to be tested with an oven. In particular, PET rolls are a very short supply in the entire market. Generally, the length of PET rolls is more than 80 to 120 cm, and the price of films with a thickness of 3-5 filaments is very high (white and transparent)
