    Tus neeg saib xyuas meej; pigment stabilizer; colloidal stabilizer; Nws yog tsuas yog siv rau npias kom meej meej thiab zoo stabilizing (siv tus nqi 8 ~ 20g / 100L, khaws cia rau 24h thiab tshem tawm nws los ntawm kev pom), thiab tseem tuaj yeem siv ua ke nrog enzymes (protease) thiab protein adsorbents. Nws kuj yog siv los qhia meej cov cawv thiab ua kom ruaj khov kom tsis txhob muaj xim (siv tus nqi 24 ~ 72g / 100L).

    Polyvinylpyrrolidone (PVP) yog ib qho polymer ntawm vinylpyrrolidone. Vim nws cov degree sib txawv ntawm polymerization, nws tuaj yeem muab faib ua PvP soluble thiab insolublePVPP (polyvinylpolypyrrolidone). Tus txheeb ze molecular hnyav ntawm soluble PVP yog 8000 ~ 10000. Nws tuaj yeem siv los ua cov dej nag los nag nrog polyphenols. Nrog rau txoj kev no, nws yog ib qho yooj yim kom muaj cov seem PVP hauv cov cawv. Lub koom haum saib xyuas kev noj qab haus huv hauv ntiaj teb tsis pom zoo kom siv PVP vim tias nws muaj kev cuam tshuam rau tib neeg lub cev. Nyob rau hauv xyoo tas los no, kev siv cov PVP soluble tsis tshua muaj. Insoluble PVPP tau siv hauv kev lag luam npias txij thaum xyoo 1960s. Nws cov txheeb ze huab hwm coj ntau dua 700000. Nws yog ib qho polymer insoluble tsim los ntawm kev sib txuas ntxiv thiab polymerization ntawm PVP. Nws tuaj yeem siv los ua ib qho adsorbent rau polyphenols nrog cov nyhuv zoo.

    PolyvinylpyrrolidonePVP yog ib qho ntawm peb yam tshuaj tshiab. Nws tuaj yeem siv los ua cov kua nplaum rau cov ntsiav tshuaj, granules thiab txhaj tshuaj, kev pab cuam txaus rau cov tshuaj ntsiav, dispersant rau kev npaj ua kua thiab cov xim, lub stabilizer rau cov enzymes thiab cov tshuaj kub kub, coprecipitant rau cov tshuaj insoluble, tshuaj tua kab mob thiab lubricant rau ophthalmic tshuaj. , thiab lwm yam hauv kev lag luam, nws yog siv los ua foaming polystyrene auxiliary agent, gelling agent, stabilizer, fiber ntau kho tus neeg saib xyuas, daim ntawv ua tus neeg sawv cev, cov nplaum thiab cov thickener rau ncua kev kawm ntawv polymerization. Polyvinylpyrrolidone PvP thiab nws cov copolymer cap yog cov ntaub ntawv tseem ceeb rau cov tshuaj pleev ib ce. Lawv feem ntau yog siv los ua cov tshuaj tua kab mob plaub hau. Cov zaj duab xis tsim ntawm cov plaub hau yog elastic thiab ci, muaj kev ua tau zoo combing, tsis kov plua plav, thiab siv cov resins ntawm txawv specifications, uas muaj peev xwm ua tau raws li ntau yam txheeb ze av noo. Yog li ntawd, lawv yog indispensable raw khoom rau styling plaub hau emulsion, plaub hau gel thiab mousse. Nws kuj tseem siv tau los ua daim tawv nqaij moisturizer, cream raws plaub hau dye dispersant thiab ua npuas ncauj stabilizer hauv tshuaj pleev ib ce los txhim kho qhov sib xws ntawm cov tshuaj zawv plaub hau. Insoluble PVP yog ib qho stabilizer rau npias thiab kua txiv hmab txiv ntoo, uas tuaj yeem txhim kho nws cov pob tshab, xim thiab saj.
