Polyvinylpyrrolidone Yambukiranya PVPP Cas 25249-54-1
Polyvinylpyrrolidone ihuza (PVPP) ni polymer ihuza imiyoboro idashobora gushonga mu mazi, acide ikomeye, ibishingwe bikomeye, hamwe n’umusemburo rusange w’ibinyabuzima, byakozwe na polymerisation ya vinyl pyrrolidone monomers mubihe byihariye. Nka polymer yingenzi yibicuruzwa byiza bya shimi, PVPP ifite ibintu byinshi byiza kandi bidasanzwe, kandi yakoreshejwe cyane mumavuta yo kwisiga, ibiryo, ubuvuzi nizindi nzego.

PVPP, nkibicuruzwa byingenzi bya polymer byiza, bifite ibintu byinshi byiza kandi bidasanzwe, kandi byakoreshejwe cyane mumavuta yo kwisiga, ibiryo, ubuvuzi nizindi nzego. Bitewe nuburemere buke bwa molekuline hamwe nuburyo buhuza imiterere ya polyvinylketone ihuza, ntishobora gushonga mumazi ariko irashobora gutuma byihuse imiyoboro yayo yaguka kandi ikangirika mugihe uhuye namazi. PVPP ikoreshwa cyane nk'umuti wo gusenya ibinini mu buvuzi, ndetse na stabilisateur yo guhagarika, umukozi uhuza ibikoresho bya farumasi, hamwe n'umukozi uhuza tannine na polifenol mu biyobyabwenge bishingiye ku bimera.
