Pov tseg polyethylene terephthalate (PET) tuaj yeem degrade loj heev tom qab ib lossis ntau qhov kev kho mob. Yog tias tsis muaj kev ntsuas kho thiab siv ncaj qha rau hauv kev tsim khoom, kev ua haujlwm thiab cov khoom tsim tawm yuav raug cuam tshuam. Cov khoom siv kho tshuab yuav tsis zoo, cov tsos yuav daj, tsis tuaj yeem ua raws li cov kev xav tau ntawm kev siv, ua rau kev ua haujlwm tsis zoo ntawm polyester, txo cov yam ntxwv viscosity ntawm polyester, discoloration, carboxyl nce, tsis tuaj yeem ua tau raws li qhov yuav tsum tau siv.
Nyob rau tib lub sij hawm, vim PET iav hloov kub thiab melting point kuj yog siab, pwm kub kub, qeeb crystallization tus nqi, thiab nrog rau cov resin molecular hnyav thiab txo, siv lead ua qauv yog tsis sib xws, txoj kev tsim yog ib qho nyuaj, sib sau lub voj voog. ntev, khoom nto ntxhib, ci iab. Lub zog tsis zoo, tsis zoo cuam tshuam toughness thiab siab nqus dej ntawm PET zoo heev txwv qhov kev siv hluav taws xob theem nrab.
Qhov piv txwv no siv cov khoom pov tseg PET los npaj PET toughening cov ntaub ntawv, los ntawm kev ntxiv cov additives los uaPET toughening khoom, tuaj yeem npaj nrog cov khoom siv zoo, muaj kev cuam tshuam zoo, zoo flexural tsis kam, roj tsis kam, roj tsis kam, acid thiab alkali tsis kam ntawm PET toughening khoom. Thiab cov organic hnyav, kub thiab tsis kub tsis kam, tsis muaj tshuaj lom, tsis qab,pob tshab zoo PET cov ntaub ntawv.
