Polyvinyl Alcohol thiab VAE Coating: Yuav ua li cas yog cov kev txawv ntawm lawv thiab cov txiaj ntsig uas lawv muab

Cov txheej txheem nrog Polyvinyl Alcohol tau txais kev siv ntev ntev. Qhov no rov qab qhia tau hais tias tus nqi tu siab rau cov txheej txheem xim hauv ib puag ncig nyuaj tau raug tshem tawm tag nrho. Cov txheej txheem uas tsim los ntawm kev sib xyaw VAE thiab PVA emulsions muaj kev ruaj khov zoo heev kom tuav tau ntau qhov kev xav tsis thoob thaum tseem muaj nqi tsim nyog. Qhov no ib qho teeb meem no txhawb nqa tus neeg siv khoom txaus siab thiab yog li ntawd muab ib qho kev pom zoo tshaj lwm tus. Yog li ntawd, nrog cov ntsiab lus no los ntawm qhov chaw xim zoo tshaj nrog kev ntev ntev kom txo tus nqi qhia tau hais tias PVA yuav tsum tau siv.

Vinyl Acetate Ethylene emulsions tuaj yeem kho kom haum rau cov qauv tshwj xeeb yooj yim xws li kev nplij siab ntau, adhesion lossis dej tsis kam. Cov chaw tsim khoom txheej txheem no thiaj li tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov chaw tsis txhob cia tus qauv ntawm kev ua haujlwm poob.

Peb zoo siab heev hais tias peb tau ua tiav los tswj tau kev sib raug zoo nrog cov chaw tsim khoom Suav uas muaj peev xwm muab VAE thiab Polyvinyl alcohol nrog lwm hom emulsions kom nce qib zoo. VAE thiab Alcohol emulsions yog cov khoom raw nyuaj heev los nrhiav thiab yog li ntawd peb cov neeg siv khoom tsis tas yuav tsum mus dhau txoj kev nyuaj ntev uas peb cov pabcuam muaj zog hloov peb.
