Thoob Ntiaj Teb - Premier PVA: Polymer Zoo Rau Ntau Yam Kev Siv
Cov Ntawv Thov Tseem Ceeb
PVA siv dav hauv kev lag luam textile. Nws ua haujlwm ua tus neeg sawv cev rau qhov loj ntawm cov xov paj, txhim kho lawv lub zog thiab du thaum lub sijhawm weaving. Qhov no pab txo qhov tawg thiab txhim kho qhov zoo ntawm cov ntaub. Tom qab cov txheej txheem weaving, PVA tuaj yeem tshem tawm yooj yim los ntawm kev ntxuav, tawm hauv cov ntaub nrog nws cov yam ntxwv qub. Tsis tas li ntawd, PVA siv rau hauv kev tsim cov txheej txheem textile thiab cov nplaum, muab kev nplaum zoo thiab ruaj khov.
Hauv kev lag luam ntawv, PVA siv ua tus neeg sawv cev ntsuas qhov chaw thiab tus neeg khi. Ua tus neeg sawv cev ntsuas qhov chaw, nws txhim kho qhov tsis kam dej, lub zog, thiab kev luam tawm ntawm daim ntawv. Nws tsim ib daim nyias nyias, pob tshab rau ntawm qhov chaw ntawm daim ntawv, tiv thaiv cov kua mem kom tsis txhob kis thiab txhim kho qhov meej ntawm cov duab luam tawm. Ua tus neeg khi, PVA siv rau hauv kev tsim cov ntawv coated thiab paperboard, txhim kho qhov kev sib txuas ntawm cov txheej txheej thiab cov substrate, thiab txhim kho qhov muaj zog thiab kev ruaj khov ntawm cov khoom ntawv.
PVA kuj yog ib yam khoom tseem ceeb hauv kev lag luam nplaum. Nws muaj cov khoom nplaum zoo heev, tshwj xeeb tshaj yog rau cov khoom siv uas muaj qhov ntxeem tau xws li ntoo, ntawv, thiab ntaub. Cov nplaum PVA yog cov dej-soluble, yooj yim siv, thiab muaj lub zog sib txuas zoo. Lawv siv dav hauv kev tsim kho, rooj tog, thiab kev lag luam ntim khoom rau kev sib txuas ntau yam khoom. Tsis tas li ntawd, cov nplaum PVA tuaj yeem hloov kho nrog lwm cov khoom ntxiv kom txhim kho lawv qhov tiv taus cua sov, tiv taus dej, thiab lwm yam khoom kom ua tau raws li cov kev xav tau tshwj xeeb.
Hauv kev lag luam ntawm cov txheej pleev xim, PVA yog siv los ua tus neeg sawv cev tsim zaj duab xis. Nws tsim cov zaj duab xis pob tshab, yoog tau, thiab tiv taus dej rau ntawm qhov chaw ntawm cov khoom pleev xim, muab kev tiv thaiv tiv thaiv dej noo, tshuaj lom neeg, thiab hluav taws xob UV. Cov txheej pleev xim PVA yog siv dav hauv kev tiv thaiv ntoo, hlau, thiab yas. Lawv kuj tseem siv tau ua tus primer lossis txheej nruab nrab los txhim kho kev nplaum thiab kev ua tau zoo ntawm cov txheej pleev xim sab saud.
