Kev xa khoom sai Pvpp / Crospovidone
Txhawm rau dhau los ua theem ntawm kev npau suav ntawm peb cov neeg ua haujlwm! Txhawm rau tsim kom muaj kev zoo siab, ntxiv kev koom siab thiab pab pawg muaj kev paub ntxiv! Txhawm rau kom ncav cuag kev sib koom ua ke ntawm peb cov neeg siv khoom, cov chaw muag khoom, lub zej zog thiab peb tus kheej rau kev xa khoom saiPvpp / Crospovidone, Peb zoo siab txais tos cov neeg siv khoom, cov koom haum ua lag luam thiab cov phooj ywg los ntawm txhua qhov chaw hauv ntiaj teb los ua kev sib cuag nrog peb thiab nrhiav kev koom tes rau kev sib nrig sib zoo.

Lawv tso siab rau peb thiab ib txwm muab cov lus txib rov qab. Tsis tas li ntawd, tau hais hauv qab no yog qee qhov tseem ceeb uas tau ua lub luag haujlwm tseem ceeb hauv peb txoj kev loj hlob zoo hauv lub tebchaws no.
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.PVPPNws 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.
