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

I-Polyvinylpyrrolidone cross-linked (PVPP) iyi-polymer exhumene ne-cross-linked enganyibiliki emanzini, kuma-asidi aqinile, ezisekelweni eziqinile, kanye nasezithambisweni eziphilayo ezijwayelekile, ezakhiwe yi-polymerization yama-monomers e-vinyl pyrrolidone ngaphansi kwezimo ezithile. Njengomkhiqizo obalulekile wamakhemikhali we-polymer fine, i-PVPP inezakhiwo eziningi ezinhle kakhulu neziyingqayizivele, futhi isetshenziswe kabanzi ezimonyweni, ekudleni, emithini nakweminye imikhakha.

Isicelo

I-PVPP, njengomkhiqizo obalulekile wamakhemikhali amahle e-polymer, inezakhiwo eziningi ezinhle kakhulu neziyingqayizivele, futhi i-cross linked polyvinylpyrrolidone isetshenziswe kabanzi ezimonyweni, ekudleni, emithini nakweminye imikhakha. Ngenxa yesisindo esikhulu sama-molecule kanye nesakhiwo sokuxhumanisa se-cross-linked polyvinylketone, i-polyvinylpolypyrrolidone pvpp ayincibiliki emanzini kodwa ingabangela ngokushesha ukuthi isakhiwo sayo senethiwekhi sande futhi siqhekeke lapho sihlangana namanzi. I-PVPP isetshenziswa kabanzi njenge-ejenti yokuqhekeka kwamaphilisi kwezokwelapha, kanye ne-suspension stabilizer, i-ejenti yokuhlanganisa izingxenye zemithi, kanye ne-ejenti yokuhlanganisa ama-tannins nama-polyphenols emithini esekelwe ezitshalweni.
