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

I-Polyvinylpyrrolidone cross-linked (PVPP) i-polymer edibeneyo edibeneyo engaxutywanga emanzini, i-acids eqinile, iziseko eziqinileyo, kunye ne-solvents ye-organic jikelele, eyenziwa yi-polymerization ye-vinyl pyrrolidone monomers phantsi kweemeko ezithile. Njengemveliso ebalulekileyo yeekhemikhali zepolymer, i-PVPP ineempawu ezininzi ezibalaseleyo nezikhethekileyo, kwaye isetyenziswe ngokubanzi kwizinto zokuthambisa, ukutya, amayeza nakwamanye amacandelo.

Isicelo

I-PVPP, njengemveliso yeekhemikhali zepolymer ebalulekileyo, ineempawu ezininzi ezibalaseleyo nezikhethekileyo, kwaye isetyenziswe ngokubanzi kwizithambiso, ukutya, amayeza kunye nezinye iinkalo. Ngenxa yobunzima obuphezulu be-molecular kunye ne-cross-linking structure ye-polyvinylketone e-cross-linked, ayinyibiliki emanzini kodwa inokubangela ngokukhawuleza ukuba isakhiwo sayo sothungelwano sandiswe kwaye sihlanjululwe xa sidibana namanzi. I-PVPP isetyenziswa ngokubanzi njenge-agent edibeneyo yokuchithwa kweepilisi kwiyeza, kunye ne-suspension stabilizer, i-agent eyinkimbinkimbi yamacandelo amayeza, kunye ne-agent eyinkimbinkimbi ye-tannins kunye ne-polyphenols kwiziyobisi ezisekelwe kwizityalo.
