Tus neeg sawv cev ua kom pom tseeb; tus neeg sawv cev ua kom xim ruaj khov; tus neeg sawv cev ua kom colloidal ruaj khov; Nws feem ntau yog siv rau kev ua kom npias pom tseeb thiab ua kom ruaj khov zoo (tus nqi siv 8 ~ 20g / 100L, khaws cia rau 24 teev thiab tshem tawm los ntawm kev lim dej), thiab kuj tseem siv tau ua ke nrog cov enzymes (protease) thiab cov protein adsorbents. Nws kuj tseem siv los ua kom cov cawv txiv hmab pom tseeb thiab ua tus neeg sawv cev kom tiv thaiv kev hloov pauv xim (tus nqi siv 24 ~ 72g / 100L).

Polyvinylpyrrolidone (PVP) yog ib qho polymer ntawm vinylpyrrolidone. Vim nws cov degree polymerization sib txawv, nws tuaj yeem muab faib ua soluble PvP thiab insolublePVPP (polyvinylpolypyrrolidone). Qhov hnyav molecular ntawm cov PVP uas yaj tau yog 8000 ~ 10000. Nws tuaj yeem siv ua cov khoom ua kom sai sai nrog polyphenols. Nrog txoj kev no, nws yooj yim kom muaj PVP seem hauv cawv. Lub koom haum kev noj qab haus huv thoob ntiaj teb tsis pom zoo kom siv PVP vim nws muaj cov nyhuv sib sau ua ke hauv tib neeg lub cev. Nyob rau xyoo tas los no, kev siv cov PVP uas yaj tau tsawg heev. Cov PVPP uas tsis yaj tau siv hauv kev lag luam npias txij li thaum xyoo 1960. Nws qhov hnyav txheeb ze yog ntau dua 700000. Nws yog cov polymer uas tsis yaj uas tsim los ntawm kev sib txuas ntxiv thiab polymerization ntawm PVP. Nws tuaj yeem siv ua cov khoom nqus rau polyphenols nrog cov txiaj ntsig zoo.

PolyvinylpyrrolidonePVP yog ib qho ntawm peb yam tshuaj tshiab. Nws siv tau ua cov tshuaj sib xyaw ua ke rau cov ntsiav tshuaj, cov hmoov thiab cov tshuaj txhaj, cov tshuaj pab ntws rau cov tshuaj ntsiav, cov tshuaj dispersant rau cov kua thiab cov xim, cov tshuaj stabilizer rau cov enzymes thiab cov tshuaj rhiab heev rau cua sov, cov tshuaj sib xyaw ua ke rau cov tshuaj tsis yaj, cov tshuaj tua kab mob thiab cov roj nplua nyeem rau cov tshuaj qhov muag, thiab lwm yam. Hauv kev lag luam, nws siv ua tus neeg sawv cev rau polystyrene ua npuas ncauj, tus neeg sawv cev gelling, tus neeg sawv cev stabilizer, tus neeg sawv cev kho fiber, tus neeg sawv cev ua ntawv, cov nplaum thiab cov khoom tuab rau kev sib xyaw ua ke.PolyvinylpyrrolidonePvP thiab nws lub hau copolymer yog cov khoom siv tseem ceeb rau cov tshuaj pleev ib ce. Lawv feem ntau yog siv los ua cov neeg sawv cev rau cov plaub hau. Cov zaj duab xis uas tsim rau ntawm cov plaub hau yog elastic thiab ci ntsa iab, muaj kev ua tau zoo heev, tsis kov cov hmoov av, thiab siv cov resins ntawm ntau yam kev qhia tshwj xeeb, uas tuaj yeem ua tau raws li ntau yam huab cua noo noo. Yog li ntawd, lawv yog cov khoom siv tseem ceeb rau kev pleev cov plaub hau emulsion, plaub hau gel thiab mousse. Nws kuj tseem siv tau ua cov tshuaj pleev rau daim tawv nqaij, cov tshuaj pleev xim rau plaub hau thiab cov tshuaj ua npuas dej stabilizer hauv cov tshuaj pleev ib ce kom txhim kho qhov sib xws ntawm cov tshuaj zawv plaub hau. Insoluble PVP yog cov tshuaj stabilizer rau npias thiab kua txiv hmab txiv ntoo, uas tuaj yeem txhim kho nws cov pob tshab, xim thiab saj.
