Piav qhia
Saib xyuas
PVA qhov zoo nkauj yog dawb flake, granular lossis powdery solid (low-alkali alcoholysis txheej) lossis dawb flocculent solid (high-alkali alcoholysis txheej). Nws yog ib hom polymer soluble hauv dej nrog kev siv dav, thiab nws cov haujlwm yog nyob nruab nrab ntawm yas thiab rubber. Nws muaj qhov tshwj xeeb muaj zog adhesion, film flexibility, roj tiv thaiv, surface activity, gas barrier, wear resistance thiab lwm yam.

Kev Tiv Thlaj Hluav
Acrylamide (nyob rau hauv PAM) tau los ua "ntawv thiaj daj" ntawm kev tiv thlaj hluav thiab ua haujlwm nrog cov qauv ntawm kev lag luam hluav, rho kom zoo thiab ceev ua siab, thiab sau cua. Nws muaj peev xwm kho kom zoo dua (tsim "ib qhov kho kom zoo rau hauv hluav", txo kev sau kom zoo li 50%), tso cua so (thoob qab hluav thiab hluav uas tsis nyob deb, txo kev so li 78%), thiab ua kom zoo (ua kom zoo li 40% thiab ua kom lub microorganism ua haujlwm).
PVA Film
Los ntawm qhov cua so nrog raw material ntawm PVA film, polyvinyl alcohol tau pom tias muaj kev zoo dua hauv kev xa khoom, kev kho mob, tshuaj lom neeg thiab lwm yam kev lag luam vim tias nws txoj cai molecular thiab cov properties ntawm nws.
Kev Ncav Duab Pov
Polyvinyl alcohol raug siv los ntawm ib qho ua pov kom zoo dua kom pov zoo dua thiab kom tsis hnov mob, kom tsawg tus pov breaking hauv kev tsim kho, thiab pab kom zoo dua hauv kev tsim kho lwm yam.
Cov txog xyoo
Alcohol Polyvinyl hauv kev ncaj ncees tuaj yeem ua raws li qhov kev pab tiv thaiv, sib txuas zoo thiab ua rau yooj yim dua. Nws cov nuj nqo ua haujlwm yog tiv thaiv kho mob, sib txuas zoo thiab ua rau yooj yim dua, thiab nws yog ib qho tsim nyog rau cellulose substrates.

Khaws
Thov zam kev tsim lossis khaws cov av. Ua kom muaj kev ceev faj tiv thaiv cov hluav taws xob, nplai/kev nplai txhua lub cuab yeej. Thov zam kev tiv tauj nrog cov khoom kub lossis molten. Tsis txhob hnoos av, fumes lossis vapors los ntawm cov khoom kub. Siv cov huab cua tawm hauv cheeb tsam txheej. Ua kom muaj kev ceev faj tiv thaiv hnub ci ncaj thiab nag txhuam thaum thauj. Khaws cov tsheb thauj khoom kom huv. Thov zam kev puas tsuaj ntawm cov pob thiab khaws deb ntawm cov impurities.
