PVA Cov Nyiaj Txiag Nrog Lwm Yam Synthetic Polymers Hauv Cov Lag Luam

Biodegradable yog qhov tshwj xeeb tshaj plaws ntawm PVA thiab nws yog ib qho nta uas ua rau PVA muaj ntau dua rau cov hom lag luam uas ua raws li ib puag ncig. Qhov nta no ntxiv pab txo qis cov chaw pov tseg thiab pab txo qis qhov kub ntsha/kev hloov pauv huab cua. Yog li, thaum nws los txog rau cov lus pom zoo, kev siv PVA yuav txhawb nqa lub ntsej muag ntsuab ntawm cov tuam txhab thiab ua kom tau raws li cov kev xav tau ntawm cov neeg yuav khoom txog kev yuav khoom cov khoom uas zoo rau ib puag ncig.

Cov qauv PVA tuaj yeem tsim los ua kom haum rau cov ntawv thov tshwj xeeb thiab yog li ntawd pab cov chaw tsim khoom tsim cov khoom uas tuaj yeem daws tau ib qho kev lag luam tshwj xeeb ntawm lawv qhov xav tau. Qhov hloov pauv zoo li no yuav pab txhim kho cov haujlwm ntawm ntau yam khoom, nce lawv qhov kev ua tau zoo, thiab ua rau muaj peev xwm tsim cov kev txhim kho tshiab hauv cov lag luam xws li kev tsim kho thiab cov khoom siv rau cov neeg siv, ua rau nthuav dav cov ntawv thov ntawm PVA.

PVA tuaj yeem, txawm li cas los xij, txo tau ntxiv nqi tsim los ntawm kev ua haujlwm hauv cov qauv ua ib qho multifunctional agent lossis txhawb nqa ib PVA tuaj yeem hloov chaw. Yog tias muaj cov ntsiab cai thiab tswv yim kev lag luam uas PVA tuaj yeem txuas nrog, qhov no yuav yog qhov tseeb yuav tsum yog txoj cai ntawm kev txo nqi pom. Nws yog qhov pom tseeb tias PVA muab kev ua haujlwm zoo tshaj plaws rau tus neeg siv kawg.
