Waa maxay Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1?

Polyvinylpyrrolidone cross-linked (PVPP) waa polymer isku-dhafan oo aan lagu milmi karin biyaha, acids xooggan, saldhigyo xooggan, iyo dareerayaasha guud ee organic, oo ay sameeyeen polymerization monomers vinyl pyrrolidone oo hoos yimaada xaalado gaar ah. Sida badeecada kiimikada ah ee muhiimka ah ee polymer, PVPP waxay leedahay sifooyin aad u fiican oo gaar ah, waxaana si weyn loogu isticmaalay waxyaalaha la isku qurxiyo, cuntada, daawada iyo qaybaha kale.

Codsiga

PVPP, oo ah badeecada kiimikada wanaagsan ee polymer-ka muhiimka ah, waxay leedahay sifooyin aad u wanaagsan oo gaar ah, waxaana si weyn loogu isticmaalay waxyaalaha la isku qurxiyo, cuntada, daawada iyo qaybaha kale. Sababtoo ah miisaanka molecular ee sarreeya iyo qaabka isku-xidhka isku-xidhka polyvinylketone ee isku-dhafan, waa mid aan lagu milmi karin biyaha laakiin waxay si dhakhso ah u keeni kartaa qaab-dhismeedka shabakadeeda inay ballaariso oo ay burburto marka ay la kulmaan biyaha. PVPP waxaa si weyn loogu isticmaalaa sida wakiilka kala-goynta ee kiniiniyada ee daawada, iyo sidoo kale xasilinta ganaax, wakiilka kakan ee qaybaha dawooyinka, iyo wakiilka kakan ee tannins iyo polyphenols ee daawooyinka dhirta ku salaysan.
