Cov Txiaj Ntsig ntawm Peb PVA thiab PVOH Cov Khoom.

Kev Hwm thiab Zoo

Peb cov PVA thiab PVOH tau txais los ntawm cov chaw tsim khoom zoo tshaj plaws kom ntseeg tau tias muaj qhov purity siab raws li cov qauv thoob ntiaj teb. Qhov zoo li no ua kom ntseeg tau tias lawv yuav ua haujlwm tau zoo thaum siv hauv cov adhesive, coatings, films thiab txawm tias textiles, kev tsim kho, thiab pob.

PVA thiab PVOH Muaj rau Muag

Polyvinyl Alcohol (PVA) thiab Polyvinyl Acetate (PVOH) yog ob qho ntawm cov polymer ntau hom uas feem ntau. Thaum ob qho no yog nyob rau hauv tib pawg, lawv cov khoom xyaw tshuaj ua rau lawv txawv. PVA yog soluble hauv dej, thiab muaj cov peev xwm tsim cov yeeb yaj kiab uas ua rau nws muaj nuj nqis hauv textile thiab packaging industries. Hauv lwm sab, PVOH kuj yog soluble hauv dej tab sis muaj cov khoom txawv hauv kev nplij siab. PVOH yog siv dav hauv adhesives thiab coatings. Yog li ntawd, nws yog qhov tseem ceeb heev kom nkag siab txog cov khoom no tshwj xeeb thaum txiav txim siab txog qhov khoom siv rau ib qho kev thov kom txhim kho thiab muaj nuj nqis.

Cov Lus Nug Nrov Tshaj Tawm txog PVA thiab PVOH

Dab tsi yog qhov txawv ntawm PVA thiab PVOH?

PVA yog ib qho polymer tsim los nrog cov khoom siv ua yeeb yaj kiab siab, zoo rau cov khoom ntim, textile thiab adhesive applications thiab soluble hauv dej. PVOH yog ib qho polymer soluble hauv dej uas feem ntau siv rau nws cov yam ntxwv adhesive, haum rau coatings thiab construction.
Txawm hais tias ob qho PVA thiab PVOH yog soluble hauv dej lawv tsis yog siv hloov pauv vim lawv muaj cov khoom thiab kev siv txawv. Ib tug yuav tsum siv polymer tsim nyog rau cov kev xav tau tshwj xeeb ntawm qhov project.
