Polyvinylpyrrolidone oo leh CAS 9003-39-8
Polyvinylpyrrolidone (PVP) waa polymer ka samaysan vinylpyrrolidone, kaas oo loo qaybin karo PVP milmi kara iyo PVPP aan milmi karin sababtoo ah heerka kala duwan ee polymerization-ka. Miisaanka molecular ee qaraabada ah ee PVP milmi kara waa 8000~10000, kaas oo loo isticmaali karo sidii xal-haye.

2. Badanaa waxaa loo isticmaalaa sidii wakiil caddayn ah oo loogu talagalay biirka, khalka, khamriga, iwm.
3. Waxaa loo isticmaalaa dareere joogto ah oo loogu talagalay koromagrafiga gaaska
4. Isku-dhafka PVP-I oo ah jeermis dile
5. Jeermis dileyaal loogu talagalay caafimaadka, beeraha iyo xannaanada xoolaha. Waxaa loo isticmaalaa jeermiska maqaarka iyo xuubka xabka.
6. Marka loo isticmaalo qurxinta maalinlaha ah, PVP iyo copolymers waxay leeyihiin sifooyin firfircoon oo kala firdhisan iyo sameynta filimada, waxaana loo isticmaali karaa dareere qaabeyn, wakiilka qurxinta ee buufinta timaha iyo mousse, wakiilka hadhka ee qaboojiyaha timaha, xasiliyaha xumbo ee shaambo, wakiilka qaabeynta hirarka, iyo wakiilka kala firdhiyaha iyo isku xirnaanta ee rinjiga timaha.
7. Waxaa loo isticmaalaa in lagu nuugo phenols iyo tannic acid laga soo saaro biyaha si loo nadiifiyo ensaymes-ka dhirta. Waxaa loo isticmaalaa sidii nuuge chromatographic ah si loo kala saaro asiidhyada udgoonka leh, aldehydes iyo phenols.
