| POVIDONE-K90 | ( C6H9NO )n |
Povidone (polyvinylpyrrolidone, PVP) inoshandiswa muindasitiri yemishonga senzira yekugadzira polymer yekuparadzira nekumisa mishonga. Inoshandiswa zvakasiyana-siyana, kusanganisira sechinobatanidza mapiritsi nemakapisi, firimu rekugadzirisa mhinduro dzemaziso, kubatsira mukuwedzera kunaka kwezvinwiwa nemapiritsi anotsengwa, uye sechinamira che transdermal systems.
Povidone ine fomura yemamorekuru ye (C6H9NO)n uye inoonekwa seupfu huchena kusvika husina kuchena. Mafomura ePovidone anoshandiswa zvakanyanya muindasitiri yemishonga nekuda kwekugona kwawo kunyungudika mumvura nemumafuta. Nhamba ye k inoreva avhareji yehuremu hwemamorekuru epovidone. MaPovidone ane K-values yakakwira (kureva, k90) haawanzo kupihwa nejekiseni nekuda kwehuremu hwawo hwakawanda hwemamorekuru. Huremu hwakawanda hwemamorekuru hunodzivirira kubuda kwetsvo uye hunotungamira mukuunganidzwa mumuviri. Muenzaniso unozivikanwa zvikuru wemafomura epovidone ipovidone-iodine, mushonga unokosha wekuuraya utachiona.
Inoyerera isina kuzara, hupfu chena, yakasimba, haitsamwisi, inonyungudika mumvura uye ethnol, yakachengetekauye zviri nyore kushandisa,. Inoshanda mukuuraya mabhakitiriya, mavhairasi uye epiphytes. Inoenderana nepamusoro penzvimbo zhinji.
Inowanikwa sehupfu hunoyerera, hutsvuku, hahutsamwisi uye hwakagadzikana, hunonyunguduka mumvura nedoro, hahunyungudike mu diethylethe ne chloroform.

Polyvinylpyrrolidone inowanzova muchimiro cheupfu kana mushonga. PVP inowanikwa muzvizoro mousse, eruption, uye bvudzi, pendi, printing ink, textile, printing uye dyeing, machubhu emifananidzo yemavara anogona kushandiswa sezvinhu zvinofukidza pamusoro, zvinoparadzira, zvinosimbisa, zvinosunga. Mukurapa ndimo munoshandiswa zvakanyanya zvinhu zvinosunga mapiritsi, granules nezvimwewo.
