Cov khoom siv PVC yog ib hom khoom siv hluavtaws, thiab nws yog ib qho ntawm cov ntaub ntawv nrog cov khoom lag luam loj hauv lub ntiaj teb. Nws tsis tuaj yeem siv ib leeg, thiab yuav tsum raug txheej txheem ua ntej nws tuaj yeem siv tau. EVA cov khoom siv yog ib yam tshiab ntawm cov khoom siv rau ib puag ncig ntawm cov yas ua npuas dej, tsim nyog rau kev ua cov tub yees txias, cov raj xa pa, cov pa roj carbon txhuam, cov ntim khoom thiab cov khoom siv txhua hnub. Muaj ntau qhov sib txawv ntawm ob cov ntaub ntawv no, yog li nyob rau lub sijhawm txuas ntxiv, Xiaoli Hongli yuav piav qhia luv luv ntawm cov ntaub ntawv PVC thiab EVA.
Cov khoom siv PVC tau muab faib ua cov tsis muaj kuab lom thiab ib puag ncig thiab tsis muaj kuab lom thiab ib puag ncig. EVA cov ntaub ntawv yog txhua yam khoom siv ib puag ncig. Qhov txheej txheem ntawm EVA yog mos, lub zog tensile yog zoo dua li PVC, thiab cov xav tias yog lo. Cov khoom siv ob qho no yog xim dawb thiab pob tshab. Kev saib thiab txav ntawm cov khoom siv EVA zoo heev ntawm cov khoom siv PVC, thiab kev saib xyuas yuav tsum them rau qhov sib txawv.
PVC: Ntuj daj ntseg zoo nkauj, ci ci. Lub pob tshab yog qhov zoo dua li polyethylene thiab polystyrene, zuj zus dua li polystyrene. Ua raws li tus nqi ntawm cov tshuaj txhab ntxiv, nws muab faib ua mos thiab tawv polyvinyl chloride. Cov khoom lag luam muag muag muag thiab cov khoom siv nyuaj, thiab lawv muaj lub ntsej muag muaj. , Thiab qis dua polypropylene, yuav muaj whitening tshwm sim ntawm qhov inflection.
EVA: Qhov ua tau zoo ntawm EVA muaj kev sib raug zoo nrog cov ntsiab lus ntawm vinyl acetate. Thaum cov ntsiab lus ntawm VA ntau ntxiv, nws txoj kev tiv taus hluav taws xob, hloov pauv yooj yim, yoog raws, pob tshab, solubility, kev nyuaj siab tiv thaiv thiab cuam tshuam kev ua haujlwm yuav ua kom zoo dua. ; Thaum cov ntsiab lus ntawm VA poob qis, txoj kev nruj, tawg tsis kam thiab hluav taws xob rwb thaiv tsev ntawm EVA yuav nce ntxiv.
