Kodi Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1 ndi chiyani?

Polyvinylpyrrolidone cross-linked (PVPP) ndi polima cholumikizira cholumikizira chomwe sichisungunuka m'madzi, ma acid amphamvu, maziko amphamvu, ndi zosungunulira zonse za organic, zopangidwa ndi polymerization ya vinyl pyrrolidone monomers pansi pamikhalidwe yapadera. Monga chinthu chofunikira kwambiri chopangira polima, PVPP ili ndi zinthu zambiri zabwino kwambiri komanso zapadera, ndipo yakhala ikugwiritsidwa ntchito kwambiri muzodzola, chakudya, mankhwala ndi zina.

Kugwiritsa ntchito

PVPP, monga chinthu chofunika kwambiri polima mankhwala abwino, ili ndi zinthu zambiri zabwino kwambiri komanso zapadera, ndipo yakhala ikugwiritsidwa ntchito kwambiri muzodzoladzola, zakudya, mankhwala ndi zina. Chifukwa cha kulemera kwakukulu kwa mamolekyu ndi mawonekedwe olumikizirana a polyvinylketone yolumikizana ndi mtanda, imasungunuka m'madzi koma imatha kupangitsa kuti maukonde ake achuluke ndikuwonongeka akakumana ndi madzi. PVPP imagwiritsidwa ntchito kwambiri ngati mankhwala osokoneza bongo pamapiritsi a mankhwala, komanso kuyimitsidwa kokhazikika, mankhwala opangira mankhwala opangira mankhwala, komanso mankhwala osokoneza bongo a tannins ndi polyphenols mu mankhwala opangidwa ndi zomera.
