Identifikacija tališča surovine iz PET plastičnih steklenic
Mar 27, 2022
Med procesom predelave in proizvodnje je treba določiti tališče PET, surovine PET plastenk. Kako razlikovati PET z visoko{0} temperaturo in PET z nizko temperaturo{1}? Naslednje bo predstavilo posebno metodo razlikovanja:
If you have a melting point tester, I believe you will easily get it. When igniting and burning, the wire is stretched and broken. If the broken wire can be rolled into several rolls, it means that the melting point is normal. 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, so you can test more yourself.
Poleg tega pri vžigu, če se hitro topi, pomeni, da je tališče nizko, in če zažgana steklenica postane še posebej črna, pomeni, da je tudi tališče nizko, in če diši zelo sladko, je lahko tudi ker je tališče nizko. . To je rekel starec.
1. Smell the taste first, the taste of PET is different from ordinary plastics. Burn it with a lighter, then it will smell very aromatic and comfortable (burn a bottle and smell it), if there are other ingredients in the PET, the smell is very pungent. There is a bottle that contains SEBS ingredients that can't be used.
2. Pri gorenju potegnite žico na vžigalnik, da vidite, ali je dolžina žice dolga, nato prekinite vlečeno žico in preverite prelomno točko na sredini, da vidite, ali je žica zavita v majhen krog. Visoko tališče. Toda na splošno, če je tableta s stekleničko, to ne bi smelo biti velik problem. Najbolj kritična točka! Treba je razlikovati, ali vsebuje PVC, kar je smrtna poškodba PET.
3. Če je goreči del pretemen ali olje zelo hitro pade, je večina tališč nenormalnih, kar pogosto najdemo v PET foliji.
Others: When igniting and burning, the wire will be broken after being stretched. If the broken wire can be rolled into several rolls, it means that the melting point is normal. Because of my lack of experience in this aspect, I can't specify a few rolls to be qualified. In addition, when igniting, if it melts quickly, it means the melting point is low, and the burned bottle becomes particularly black, which means the melting point is also low. If the taste smells particularly sweet, it may also be that the melting point is low.
