Pov tsegPET (polyethylene terephthalate)degrades hnyav heev tom qab ib los yog ntau txoj kev kho mob. Yog tias tsis muaj kev ntsuas los them nyiaj rau kev siv ncaj qha hauv kev tsim khoom, kev ua haujlwm thiab cov khoom tsim tawm yuav raug cuam tshuam. Cov cuab yeej cuab tam yuav tsis zoo, cov tsos yog daj, tsis tuaj yeem ua raws li cov kev cai siv, ua rau kev ua haujlwm tsis zoo ntawm polyester, txo cov yam ntxwv viscosity ntawm polyester, discoloration, carboxyl pawg nce, tsis tuaj yeem ua raws li kev siv.
Nyob rau tib lub sijhawm, vim tias PET iav hloov kub thiab melting point yog qhov siab, pwm kub yog siab, crystallization ceev qeeb thiab txo qis nrog qhov nce ntawm molecular hnyav ntawm resin, yog li cov qauv siv lead ua tsis sib xws, cov txheej txheem molding yog qhov nyuaj. , lub voj voog molding yog ntev, cov khoom nto yog ntxhib thiab ci iab. Qhov tsis zoo ntawm lub zog tsis zoo, kev cuam tshuam tsis zoo thiab kev nqus dej siab heev txwv tsis pub siv cov khoom siv thib ob ntawm PET.
Qhov piv txwv no siv pov tsegPET khoomlos npaj PET toughening khoom, los ntawm kev ntxiv additives ua PET toughening khoom, tuaj yeem npaj cov khoom siv zoo, muaj kev cuam tshuam zoo, kev ua haujlwm zoo folding, roj tsis kam, roj tsis kam, acid thiab alkali tsis kam thiab lwm yam khoom zoo ntawm PET toughening khoom. Nrog cov kuab tshuaj organic, kub thiab kub tsis kam, tsis muaj tshuaj lom, tsis qab, zoo transparency PET khoom.
