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 tau raws li qhov yuav tsum tau siv, ua rau kev ua haujlwm ntawm polyester tsis zoo, 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 sijhawm, vim PET iav hloov pauv kub thiab melting point yog qhov siab, pwm kub kub, qeeb crystallization tus nqi, thiab nrog rau qhov nce ntawm resin molecular hnyav thiab txo, siv lead ua qauv tsis sib xws, txoj kev sib sau yog qhov nyuaj, kev tsim lub voj voog yog. 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.
