Ua kom peb cov neeg ua haujlwm muaj kev npau suav zoo siab dua, sib koom siab dua, thiab muaj kev paub ntau dua! Ua kom peb cov neeg siv khoom, cov neeg muag khoom, lub zej zog thiab peb tus kheej tau txais txiaj ntsig zoo.Pvpp / Crospovidone, Peb txais tos cov neeg siv khoom, cov koom haum lag luam thiab cov phooj ywg los ntawm txhua qhov chaw hauv ntiaj teb los tiv tauj peb thiab nrhiav kev koom tes rau kev sib koom tes zoo.
Ua kom peb cov neeg ua haujlwm muaj kev npau suav! Los tsim kom muaj ib pab neeg zoo siab dua, sib koom siab dua thiab muaj kev paub ntau dua! Los ua kom peb cov neeg siv khoom, cov neeg muag khoom, lub zej zog thiab peb tus kheej tau txais txiaj ntsig zoo.Crospovidone, Peb tau txais kev lees paub ntau ntawm cov neeg siv khoom thoob plaws ntiaj teb. Lawv ntseeg peb thiab ib txwm muab cov xaj rov ua dua. Ntxiv mus, 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 thaj chaw no.
Polyvinylpyrrolidone cross-linked (PVPP)yog ib qho polymer txuas 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 ib qho tseem ceeb polymer khoom zoo tshuaj,PVPPmuaj ntau yam khoom zoo heev thiab tshwj xeeb, thiab tau siv dav hauv kev kho kom zoo nkauj, 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 tau siv dav hauv kev kho kom zoo nkauj, khoom noj, tshuaj thiab lwm yam teb. Vim yog qhov hnyav molecular siab thiab cov qauv sib txuas ntawm cov polyvinylketone sib txuas, nws 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.
