PVOH dab polymer uas tsha tshuaj lwb thiab muaj kev cua kom paub tias tsis txhob tsha tshuaj

PVOH dab polymer uas tsha tshuaj lwb thiab muaj kev cua kom paub tias tsis txhob tsha tshuaj

Peb muab PVOH, uas kuj hu ua polyvinyl alcohol, yog dab polymer uas tsha tshuaj lwb thiab muaj kev cua kom paub tias tsis txhob tsha tshuaj, uas muaj kev ua kom zoo thiab ceev. PVOH muaj kev ua film zoo, kev nyiaj ib tug, kev tiv thaiv los ntawm tshuaj, thiab kev tiv thaiv khwv. Nws tau siv ntau hauv kev tsim daim ntawv, kev tsim khaub ncaws, kev tsim tsev nyiaj ib tug, daim ntawv, thiab kev tsim tshuaj tseg uas xav tau kev nyab xeeb thiab zoo tagnrho.

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.
