Kev Siv Khoom Siv Ua Ntau Rau Txhua Qhov Chaw

Peb nyuaj siab kom paub txog kev siv khoom lag luam thiab xaiv cov khoom tshwj xeeb uas tsim nyog rau lawv, txawm tias tsis muab khoob tshwj tsis muaj ntau yam, vim kho kom zoo dua rau kev siv khoom kuaj pov tseg.

Cov khoom sib xws

PVOH, uas tseem hu ua polyvinyl alcohol, yog ib hom polymer tsim los uas tuaj yooj sib txawv nrog dej uas muaj qhuj chaw tsim film, kev nyuaj siab, thiab kev nyob siab txaus siab. PVOH tau tsim los los ntawm kev hydrolysis tswj hwm ntawm polyvinyl acetate, thiab PVOH muaj feem qhov tuaj yeem tsim los nrog kev hloov pauv ntau thiab txoj cai hydrolysis. Nws tau siv ntau hauv kev nres film, kev nres tsho, kev nres daim ntawv, kev nres tsev nres, thiab kev tsim kho tshuaj tshwj xeeb. PVOH film muaj kev tiv thaiv tshwj xeeb rau oxygen, yog li ntawd nws tsim nyog rau kev nres noj thiab nres tshuaj. Hauv kev nres thiab kev nres, PVOH muaj kev nyuaj siab ntau rau substrates cellulose-based thiab kev tshaj tawm zoo. Qhov tshwm sim ntawm nws nrog rau kev tsim kho tshwj xeeb tshuaj tshwj xeeb tiv thaiv dej tshwm sim. Rau kev xaiv qhov chaw, kev txheeb xyuas txuj ci, lossis kev sib koom ua ke, cov neeg siv khwv tau txhaj ntaq rau kev sib tham tau.

Cov Lus Nug Nrov

Polyvinyl alcohol yog li cas thiab dab tsi ua rau nws yooj yim sib txawv?

Polyvinyl alcohol yog ib qhov linear polymer uas tuaj muab nrog hluv nyob hauv dej, paub tshwm zoo ntawm kev tsim film, kev ntxig, thiab kev nyob ncig zoo. Nws sib sau ua ke cov leej caij nrog cov elastomers, muab kev ntxig zoo, kev tiv thaiv los ntawm kab duag, thiab kev tiv thaiv los ntawm cov solvents organics. Cov caij no ua rau nws raug rau kev siv rau daim ntawv, cov ntaub, cov adhesives siv rau kev kawm, films, thiab cov ntaub ntawv siv rau kosmetics.
PVA 0588 muaj kev nyiaj tsawg thiab kev sov ntev, ua rau nws raug siv rau kev nyiaj tsawg, films siv hluv tshuab, thiab kev tsim khoom. Nws pab kev siv smoothly, suav sijhawm tsawg dua, thiab kev coj yooj yim rau kev nyiaj hauv kev tsim khoom.
PVA 217 muaj qhauv kev ua haujlwm zoo li PVA 1788 thiab tuaj yeem siv ua leem ntawm ntau yam kev siv siv tshuab ntxuav, film, thiab tshuab tshuab. Nws pab tiv thaiv kev txuas ntxiv, kev ua kom so, thiab kev tiv thaiv kom tsis txuag, thaum kuj tseem tiv thaiv kev raug sib thooj thiab kev tshuaj xyuas.
VAE emulsion siv hauv tshuab ntxuav rau tsev, siv rau tshuab ntxuav rau kab, siv rau tshuab tiv thaiv kom tsis muaj dej, thiab siv rau kev ntxuav tshuab tshuab. Nws pab tiv thaiv kev txuas ntxiv, kev tsim film nyob rau ntiv ntsuab, thiab kev ua kom so hauv ntev tsis tas yuav tshuaj plasticizers ntxiv.
