PVP (polyvinylpyrrolidone) yog ib hom polymer uas feem ntau pom muaj nyob rau hauv cov khoom siv rau plaub hau thiab ua lub luag haujlwm tseem ceeb hauv kev saib xyuas plaub hau. Nws yog ib hom tshuaj uas siv tau ntau yam, suav nrog ua tus neeg sawv cev khi, emulsifier, thickener, thiab tus neeg sawv cev ua zaj duab xis. Ntau yam khoom saib xyuas plaub hau muaj PVP vim nws muaj peev xwm tuav tau zoo thiab ua rau plaub hau yooj yim tswj.
PVP feem ntau pom muaj nyob rau hauv cov tshuaj pleev plaub hau, cov tshuaj tsuag plaub hau, thiab cov tshuaj pleev kom plaub hau zoo nkauj. Nws yog cov polymer uas yaj tau hauv dej uas yooj yim tshem tawm nrog dej lossis tshuaj zawv plaub hau. Vim tias nws yaj tau hauv dej, nws tsis tawm cov khoom seem lossis cov khoom sib sau ua ke, uas tuaj yeem ua teeb meem nrog lwm cov khoom xyaw tshuaj pleev plaub hau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm PVP hauv cov khoom siv rau plaub hau yog nws lub peev xwm los tuav tau zoo thoob plaws hnub. Qhov no ua rau nws zoo tagnrho rau kev siv rau hauv cov tshuaj pleev plaub hau thiab lwm yam khoom siv styling uas xav tau kev tuav ntev. Nws kuj muab qhov tiav zoo li ntuj uas tsis zoo li tawv lossis tsis zoo li ntuj.
Lwm qhov txiaj ntsig ntawm PVP hauv cov khoom siv plaub hau yog nws lub peev xwm los ntxiv lub cev thiab ntim rau cov plaub hau. Thaum siv rau cov plaub hau, nws pab ua kom cov plaub hau tuab dua, ua rau cov plaub hau zoo li puv dua, ntau dua. Qhov no tseem ceeb heev rau cov neeg uas muaj plaub hau zoo lossis nyias, uas tej zaum yuav nyuaj rau ua tiav qhov zoo li voluminous nrog lwm cov khoom siv plaub hau.
PVP kuj yog ib yam khoom xyaw uas muaj kev nyab xeeb uas tau txais kev pom zoo rau kev siv hauv cov khoom siv pleev kom zoo nkauj los ntawm cov koom haum tswj hwm. Nws tsis ua rau muaj kev pheej hmoo rau kev noj qab haus huv thaum siv rau hauv cov khoom tu plaub hau hauv cov nqi pom zoo. Qhov tseeb, PVP raug suav hais tias yog ib yam khoom xyaw uas muaj kev nyab xeeb thiab siv tau zoo rau hauv cov khoom siv plaub hau.
Xaus lus, PVP yog ib yam khoom muaj nqis uas pab kom cov plaub hau tuav tau zoo, ntim tau, thiab yooj yim tswj. Nws yog ib yam polymer uas feem ntau pom muaj nyob rau hauv cov khoom siv rau plaub hau, thiab muaj kev nyab xeeb rau kev siv hauv cov khoom siv pleev kom zoo nkauj. Yog tias koj tab tom nrhiav txoj hauv kev los txhim kho koj cov plaub hau tuav thiab ntim tau, xav txog kev sim cov khoom siv rau plaub hau uas muaj PVP.
