Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1
Polyvinylpyrrolidone cross-linked (PVPP) yog ib qho polymer cross-linked uas tsis yaj hauv dej, cov kua qaub muaj zog, cov hauv paus muaj zog, thiab cov kuab tshuaj organic dav dav, tsim los ntawm kev sib xyaw ntawm vinyl pyrrolidone monomers nyob rau hauv cov xwm txheej tshwj xeeb. Raws li cov khoom siv tshuaj polymer zoo tseem ceeb, PVPP muaj ntau yam khoom zoo heev thiab tshwj xeeb, thiab tau siv dav hauv cov tshuaj pleev ib ce, khoom noj, tshuaj thiab lwm yam teb.

PVPP, ua ib yam khoom siv tshuaj polymer zoo tseem ceeb, muaj ntau yam khoom zoo heev thiab tshwj xeeb, thiab cov polyvinylpyrrolidone sib txuas tau siv dav hauv cov tshuaj pleev ib ce, khoom noj, tshuaj thiab lwm yam teb. Vim yog qhov hnyav molecular siab thiab cov qauv sib txuas ntawm cov polyvinylketone sib txuas, polyvinylpolypyrrolidone pvpp tsis yaj hauv dej tab sis tuaj yeem ua rau nws cov qauv network nthuav dav thiab tawg thaum ntsib dej. PVPP siv dav ua tus neeg sawv cev tawg rau cov ntsiav tshuaj hauv tshuaj, nrog rau ua tus neeg sawv cev ncua kev ncua, tus neeg sawv cev sib xyaw rau cov khoom siv tshuaj, thiab tus neeg sawv cev sib xyaw rau tannins thiab polyphenols hauv cov tshuaj cog.
