Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1 yog dab tsi?

Polyvinylpyrrolidone cross-linked (PVPP) yog ib qho kev sib txuas ntawm cov polymer uas yog insoluble hauv dej, muaj zog acids, muaj zog hauv paus, thiab cov organic solvents, tsim los ntawm polymerization ntawm vinyl pyrrolidone monomers nyob rau hauv tej yam kev mob. Raws li ib qho tseem ceeb ntawm cov khoom siv tshuaj zoo polymer, PVPP muaj ntau yam zoo heev thiab tshwj xeeb, thiab tau siv dav hauv tshuaj pleev ib ce, zaub mov, tshuaj thiab lwm yam.

Daim ntawv thov

PVPP, raws li ib qho tseem ceeb ntawm cov khoom siv tshuaj zoo polymer, muaj ntau yam zoo heev thiab tshwj xeeb, thiab tau siv dav hauv tshuaj pleev ib ce, zaub mov, tshuaj thiab lwm yam. Vim yog qhov hnyav molecular thiab cov qauv sib txuas ntawm cross-linked polyvinylketone, nws yog insoluble hauv dej tab sis tuaj yeem ua rau nws cov qauv network nthuav dav thiab cuam tshuam thaum ntsib dej. PVPP yog dav siv los ua tus neeg sawv cev disintegration rau cov ntsiav tshuaj hauv cov tshuaj, nrog rau cov tshuaj tiv thaiv kev ncua, tus neeg sawv cev ua haujlwm rau cov khoom siv tshuaj, thiab cov neeg ua haujlwm complexing rau tannins thiab polyphenols hauv cov tshuaj nroj tsuag.
