Iyini i-Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1?

I-Polyvinylpyrrolidone cross-linked (PVPP) iyi-polymer ehlangene engancibiliki emanzini, ama-asidi aqinile, izisekelo eziqinile, kanye nezincibilikisi ezijwayelekile zezinto eziphilayo, ezakhiwe yi-polymerization ye-vinyl pyrrolidone monomers ngaphansi kwezimo ezithile.Njengomkhiqizo wamakhemikhali we-polymer obalulekile, i-PVPP inezinto eziningi ezinhle kakhulu neziyingqayizivele, futhi isetshenziswe kabanzi kwezimonyo, ukudla, imithi nakweminye imikhakha.

Isicelo

I-PVPP, njengomkhiqizo wamakhemikhali amahle we-polymer obalulekile, inezinto eziningi ezinhle kakhulu neziyingqayizivele, futhi isetshenziswe kabanzi kwezimonyo, ukudla, imithi nakweminye imikhakha.Ngenxa yesisindo samangqamuzana aphezulu kanye nesakhiwo sokuxhumanisa esiphambanweni se-polyvinylketone exhunywe ngokuphambanayo, ayincibiliki emanzini kodwa ingabangela ngokushesha ukwakheka kwayo kwenethiwekhi ukuthi inwebeke futhi ihlakazeke lapho ihlangana namanzi.I-PVPP isetshenziswa kabanzi njenge-ejenti yokuhlakaza amaphilisi emithi, kanye ne-suspension stabilizer, i-ejenti eyinkimbinkimbi yezingxenye zemithi, kanye ne-ejenti eyinkimbinkimbi yama-tannins nama-polyphenols emithini yezitshalo.
