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

Polyvinylpyrrolidone cross-linked (PVPP) waa polymer isku xiran oo aan ku milmin biyaha, asiidhyada xooggan, saldhigyada xooggan, iyo dareerayaasha guud ee dabiiciga ah, oo ay sameeyeen polymerization-ka monomers-ka vinyl pyrrolidone xaalado gaar ah. Maadaama ay tahay badeeco kiimiko oo polymer ah oo muhiim ah, PVPP waxay leedahay sifooyin badan oo aad u fiican oo gaar ah, waxaana si weyn loogu isticmaalay qurxinta, cuntada, daawada iyo meelaha kale.

Codsiga

PVPP, oo ah badeeco kiimiko oo muhiim ah oo polymer ah, waxay leedahay sifooyin badan oo aad u fiican oo gaar ah, polyvinylpyrrolidone-na isku xidhka ah ayaa si weyn loogu isticmaalay qurxinta, cuntada, daawada iyo meelaha kale. Sababtoo ah miisaanka sare ee molecular-ka iyo qaab-dhismeedka isku xidhka ee polyvinylketone-ka isku xidhka ah, polyvinylpolypyrrolidone pvpp kuma milmi karo biyaha laakiin si dhakhso ah ayuu u sababi karaa in qaab-dhismeedkiisa shabakadu uu ballaarto oo uu burburo marka uu la kulmo biyaha. PVPP waxaa si weyn loogu isticmaalaa sidii wakiil kala-goyn ah oo kiniiniyada daawada ah, iyo sidoo kale xasiliye joojin ah, wakiil isku-dhafan oo loogu talagalay qaybaha dawooyinka, iyo wakiil isku-dhafan oo loogu talagalay tannins iyo polyphenols ee daawooyinka ku salaysan dhirta.
