Poly (vinyl cawv) (PVOH, PVA, lossis PVAl) yog cov dej-soluble hluavtaws polymer. Nws muaj cov qauv zoo tagnrho [CH2CH (OH)] n. Nws yog siv hauv papermaking, textiles, thiab ntau yam txheej xim. Nws yog xim dawb (tsis muaj xim) thiab ntxhiab tsw. Qee zaum muab nkag los ua cov hlaws dai lossis cov kev daws teeb meem hauv dej. Cawv polyvinyl （PVA tsuas yog siv nyob rau hauv kev lag luam textile, raws li cov ntaub ntawv raw ntawm warp pulp, npuag tiav tus neeg sawv cev, vinylon fiber; cov xim tha xim sab hauv thiab sab nrauv ntawm lub tsev, ntawv nplaum; kev lag luam chemical siv nws ua cov tshuaj polymerization emulsifier, dispersant thiab polyvinyl formal, acetyl, butyrate aldehyde cob; daim ntawv kev lag luam siv nws los ua ntawv phaj; kev ua liaj ua teb siv nws ua cov av tsis huv, kev siv tshuaj tua kab synergist thiab polyvinyl cawv zaj duab xis; nws kuj tseem siv tau rau cov tshuaj pleev ib ce txhua hnub thiab qhov ntau dua quenching tus neeg sawv cev thiab lwm yam. Hauv kev lag luam plastics hauv kev txhaj tshuaj molding Cov tshuaj tiv thaiv, txheej txheej saum npoo, cov yeeb yaj kiab tiv taus cov roj av, textile ntau thiab tsawg thiab xov tiav; tuaj yeem sib xyaw ua tiav rau cov pa luam yeeb elastomers los siv rau hauv kev tsim cov khoom siv hluav taws xob, roj tog raj, thiab lwm yam. Tshuaj pab (viscosity nce tus neeg sawv cev); ophthalmic roj nplua nyeem.
