Umhlinzeki waseShayina i-Pvpp R ye-ejenti yewayini nobhiya
Ukuthuthuka kwethu kuncike ezintweni ezisezingeni eliphezulu, amakhono avelele kanye namandla obuchwepheshe aqiniswe ngokuphindaphindiwe kuMhlinzeki waseShayinaI-PvppR we-ejenti yewayini nobhiya, besilokhu silangazelela ukubambisana nawo wonke amakhasimende asekhaya nakwamanye amazwe. Ngaphezu kwalokho, ukwaneliseka kwamakhasimende kuyinto esiyiphishekelayo phakade.
Ukuthuthuka kwethu kuncike ezintweni ezisezingeni eliphezulu, amakhono avelele kanye namandla obuchwepheshe aqiniswe ngokuphindaphindiweI-Pvpp kanye ne-Crospovidone, Sihlala sigcizelela isimiso esithi “Ikhwalithi kanye nensizakalo kuyimpilo yomkhiqizo”. Kuze kube manje, imikhiqizo yethu ithunyelwe emazweni angaphezu kuka-20 ngaphansi kokulawulwa kwekhwalithi okuqinile kanye nensizakalo esezingeni eliphezulu.
I-Polyvinylpyrrolidone exhunywe nge-cross-linked (PVPP)iyi-polymer exhumene ne-cross-linked engancibiliki emanzini, kuma-asidi aqinile, ezisekelweni eziqinile, kanye nasezithambisweni eziphilayo ezijwayelekile, ezakhiwe yi-polymerization yama-monomers e-vinyl pyrrolidone ngaphansi kwezimo ezithile. Njengomkhiqizo wamakhemikhali obalulekile we-polymer,I-PVPPinezakhiwo eziningi ezinhle kakhulu neziyingqayizivele, futhi isetshenziswe kabanzi ezimonyweni, ekudleni, emithini nakweminye imikhakha.

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