Kev siv tseem ceeb ntawm paste pvc cob.
Polyvinyl chloride los yog PVC yog ib hom resin siv los tsim cov roj hmab thiab yas. PVC resin muaj nyob rau hauv cov xim dawb thiab hmoov daim ntawv. Nws yog tov nrog additives thiab plasticizers los tsim PVC paste resin. Pvc paste resin yog siv rau txheej, dipping, foaming, tshuaj tsuag txheej, thiab kev sib hloov. PVC paste resin muaj txiaj ntsig zoo hauv kev tsim khoom ntawm ntau yam khoom muaj nqis ntxiv xws li hauv pem teb thiab phab ntsa npog, tawv tawv, txheej txheej, hnab looj tes, thiab cov khoom lag luam slush. Cov neeg siv khoom lag luam loj kawg ntawm PVC muab tshuaj txhuam muaj xws li kev tsim kho, tsheb, luam ntawv, tawv hluavtaws, thiab hnab looj tes ua haujlwm. PVC paste resin tau siv ntau dua hauv cov kev lag luam no, vim nws cov khoom siv lub cev muaj zog, sib xws, siab gloss, thiab ci. PVC paste cob tuaj yeem kho... -
