Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1
Polyvinylpyrrolidone cross-linked (PVPP) ndi polima yolumikizidwa yomwe siisungunuka m'madzi, ma asidi amphamvu, maziko olimba, ndi zosungunulira zachilengedwe, zomwe zimapangidwa ndi polymerization ya ma monomers a vinyl pyrrolidone pansi pa mikhalidwe inayake. Monga chinthu chofunikira kwambiri cha mankhwala a polymer, PVPP ili ndi zinthu zambiri zabwino komanso zapadera, ndipo yagwiritsidwa ntchito kwambiri mu zodzoladzola, chakudya, mankhwala ndi madera ena.

PVPP, monga chinthu chofunika kwambiri cha mankhwala a polymer, ili ndi zinthu zambiri zabwino komanso zapadera, ndipo polyvinylpyrrolidone yolumikizidwa pamodzi yagwiritsidwa ntchito kwambiri mu zodzoladzola, chakudya, mankhwala ndi zina. Chifukwa cha kulemera kwakukulu kwa mamolekyulu ndi kapangidwe kolumikizana ka polyvinylketone yolumikizidwa pamodzi, polyvinylpolypyrrolidone pvpp sisungunuka m'madzi koma ingayambitse msanga kapangidwe ka netiweki yake kukula ndikusweka ikakumana ndi madzi. PVPP imagwiritsidwa ntchito kwambiri ngati chosungunula mapiritsi mu mankhwala, komanso ngati chokhazikika, chosungunula zinthu za mankhwala, komanso chosungunula zinthu za tannins ndi polyphenols mu mankhwala ochokera ku zomera.
