Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1 ni iki?

Polyvinylpyrrolidone cross-linked (PVPP) ni polymer ifitanye isano idashonga mu mazi, aside ikomeye, base zikomeye, n'ibintu biyungurura ibinyabuzima muri rusange, bikozwe no gupomera monomer za vinyl pyrrolidone mu bihe runaka. Nk'umusaruro w'ingenzi wa polymer, PVPP ifite imiterere myinshi myiza kandi idasanzwe, kandi yakoreshejwe cyane mu kwisiga, mu biribwa, mu buvuzi no mu bindi bikorwa.

Porogaramu

PVPP, nk'ikintu cy'ingenzi gikoreshwa mu buvuzi, ifite imiterere myiza kandi idasanzwe, kandi polyvinylpyrrolidone ifitanye isano yakoreshejwe cyane mu kwisiga, mu biribwa, mu buvuzi no mu bindi bice. Bitewe n'uburemere bwinshi bwa molekile n'imiterere ihuza ya polyvinylketone ifitanye isano, polyvinylpolypyrrolidone pvpp ntishongera mu mazi ariko ishobora gutuma imiterere yayo yagutse kandi igashonga iyo ihuye n'amazi. PVPP ikoreshwa cyane nk'ikintu gikwirakwiza ibinini mu buvuzi, ndetse no nk'ikintu gihagarika imiti, ikintu gitera imiterere y'ibice by'imiti, n'ikintu gitera imiterere y'ibinyabutabire bya tannins na polyphenols mu miti ikomoka ku bimera.
