Yintoni iPolyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1?

I-Polyvinylpyrrolidone cross-linked (PVPP) yi-polymer edibeneyo enganyibilikiyo emanzini, kwii-asidi ezinamandla, kwiziseko ezinamandla, nakwizinto eziphilayo ngokubanzi, ezenziwe yi-polymerization ye-vinyl pyrrolidone monomers phantsi kweemeko ezithile. Njengemveliso ebalulekileyo yekhemikhali ye-polymer fine, i-PVPP ineempawu ezininzi ezintle nezikhethekileyo, kwaye isetyenziswa kakhulu kwizithambiso, ukutya, amayeza nakwezinye iindawo.

Isicelo

I-PVPP, njengemveliso ebalulekileyo yekhemikhali ye-polymer, ineempawu ezininzi ezintle nezingaqhelekanga, kwaye i-cross linked polyvinylpyrrolidone isetyenzisiwe kakhulu kwizithambiso, ukutya, amayeza nakwezinye iindawo. Ngenxa yobunzima obukhulu beemolekyuli kunye nesakhiwo esidibanisayo se-cross-linked polyvinylketone, i-polyvinylpolypyrrolidone pvpp ayinyibiliki emanzini kodwa inokubangela ukuba isakhiwo sayo senethiwekhi sande kwaye siqhekeke xa sidibana namanzi. I-PVPP isetyenziswa kakhulu njenge-arhente yokuqhekeka kweepilisi kumayeza, kunye ne-suspension stabilizer, i-arhente yokuxinana kwamacandelo amayeza, kunye ne-arhente yokuxinana kweetannins kunye neepolyphenols kumayeza asekelwe kwizityalo.
