Peb qhov zoo hais nws tus kheej cov khoom zoo li nws tsis tangle, los yog tawg, yog li ntawd peb cov neeg muas zaub yuav ib txwm muaj kev ntseeg siab thaum tso ib qho kev txiav txim.
Polyvinylpyrrolidone cross-linked (PVPP) yog ib qho kev sib txuas ntawm 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,PVPPmuaj ntau yam khoom zoo heev thiab tshwj xeeb, thiab tau siv dav hauv tshuaj pleev ib ce, zaub mov, tshuaj thiab lwm yam.

PVPP, raws li ib qho tseem ceeb polymer zoo tshuaj cov khoom, muaj ntau yam zoo heev thiab tshwj xeeb zog, thiab tau dav siv nyob rau hauv tshuaj pleev ib ce, zaub mov, tshuaj thiab lwm yam teb. 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 kev ncua ncua kev kawm ntawv, tus neeg saib xyuas kev ua haujlwm rau cov khoom siv tshuaj, thiab cov neeg ua haujlwm complex rau tannins thiab polyphenols hauv cov tshuaj cog qoob loo.
