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.

Tsis lawm
Alcohol Polyvinyl tau ua rau muaj "kev nthuav dav" hauv cov roj ntxuav los ntawm 4 qhov: film-forming reinforcement, interface bonding, kev lag luam thiab kev kho tshuaj nrog. Qhov tseeb ntawm nws yog qhov zoo ua ke ntawm kev ceev thiab kev ua kom zoo (ua kom zoo dua qhov ua kom tsis txawv thiab sib txuas), kev ua kom haum (xav txog ob peb yam xaus thiab kev ua kom sov), thiab kev tiv thaiv kho mob thiab kev ua kom yooj yim (tsis lom neeg, ua kom raug, thiab khawm emulsion). Cov lej yuav tsum tau pom nrog lub sijhawm.
Daim Ua Rau Ntawv Hlau
Polyvinyl alcohol yog siv los tsim daim ua rau ntawv hlau, uas yuav hlau huv rau hauv dej thiab kho kom zoo rau qhov chaw nyob.
Vaj Tse Siv Lub Raj Thav Duab Siab
Polyvinyl alcohol ua tus kheej loj hauv vaj tse siv lub raj thav duab siab thiab muaj peev xwm ua kom zoo dua rau qhov sov thiab txhim kho qhov kev sib dhos ntawm lub raj hlau thiab cov ntsiab lus, ua kom qhov kev ua haujlwm tso cai thiab kho kom tsawg qhov kev txwv rau qhov chaw nyob.
Tsim Ntawv
Nyob rau hauv kev tsim ntawv, polyvinyl alcohol tau menjadi ib yam khoom siv rau kev ua kom zoo dua rau ntawv los ntawm qhov kev ua haujlwm ob peb hom ntawm "kev ua kom sov-sov ua daim ntawv hlau-kev ua kom zoo ntawm kev ntxig", qhov tseeb yog nws qhov ua kom zoo ntawm qhov sov, kev tiv thaiv dej thiab kev sau rau ntawv, thiab nws lub cev zoo, tsis muaj neeg ua rau lom neeg thiab ua kom hlau huv los ntawm kev hlau huv.

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.
