Melting point identification of pet, the hottest p

Melting point identification of plastic bottle raw material pet

how to distinguish high-temperature pet from low-temperature pet? I believe this is a question that everyone wants to know very much. Today, experts have specially sorted it out for you in the form of one question and one answer, hoping to help you

a: for recycled materials, can they be separated by naked eyes or some simple methods

b: if there is a melting point tester even when it reaches 90%, I believe you will easily handle it after cutting off the power. By the way, the price of a melting point tester is about 20000 yuan, which can be taken away like a briefcase. You'll be out of date without PET bottle chips

when igniting and burning, draw the wire. After stretching, break the wire. If the broken wire can be rolled into several rolls, it indicates that the melting point is normal. The more, the higher. Because of my lack of experience in this area, I can't specify a few volumes to be qualified. I don't have this ability. Try more by yourself

in addition, when igniting, if it melts quickly, it means that the melting point is low, and the burned bottle pieces become particularly black, which means that the melting point is also low. In addition, with the increasing proportion of plastic packaging in the packaging industry, if the taste smells particularly sweet, it may also be that the melting point is low. This is what the elder said

1. Smell it first. Pet tastes different from ordinary plastics. Burn it with a lighter, and then you will smell a very fragrant and comfortable taste (burn a bottle to smell it casually). If pet contains other ingredients, the taste is very pungent. One kind of bottle containing SEBS cannot be used

2. It seems that if the burned part is too dark or the oil drops quickly, most of the melting points are abnormal, which is often found in PET films

3. Wire drawing: when burning, pull the wire on the lighter to see if the wire is long, and then pull the pulled wire to break, and see if the broken point in the middle is rolled into a small circle. The more the wire is rolled, the higher the melting point is. But generally, if it is a bottle tablet, there should be no big problem. The most critical point! It is to distinguish whether it contains PVC, which is the fatal injury of pet

others: when igniting and burning, draw the wire. After stretching, break the wire. If the broken wire can be rolled into several rolls, it indicates that the melting point is normal. The more, the higher. Because of my lack of experience in this aspect, I can't be specific. A few volumes are qualified. They say that the employees of this experimental machine factory are very considerate. In addition, when igniting, if it melts quickly, it means that the melting point is low. In addition, if the burned bottle pieces become particularly black, it means that the melting point is also low. In addition, if the taste smells particularly sweet, it may also be that the melting point is low
