| POVIDONE-K90 | (C6H9NO) n |
Povidone (polyvinylpyrrolidone, PVP) yog siv rau hauv kev lag luam tshuaj ua ib lub tsheb polymer tsim los rau kev sib kis thiab kev dai cov tshuaj. Nws muaj ntau yam kev siv, suav nrog ua ib qho binder rau cov ntsiav tshuaj thiab cov tshuaj ntsiav, ua ib zaj duab xis rau cov tshuaj qhov muag, los pab txhawb rau cov kua tsw qab thiab cov ntsiav tshuaj zom, thiab ua ib qho nplaum rau cov kab mob transdermal.
Povidone muaj cov mis molecular ntawm (C6H9NO) n thiab zoo li hmoov dawb mus rau me ntsis dawb tawm. Cov qauv povidone siv dav hauv kev lag luam tshuaj vim lawv muaj peev xwm yaj hauv cov dej thiab cov roj yaj. Tus lej k txhais tau tias qhov hnyav molecular nruab nrab ntawm povidone. Povidones nrog K-nqi siab dua (piv txwv li, k90) feem ntau tsis muab los ntawm kev txhaj tshuaj vim lawv qhov hnyav molecular siab. Qhov hnyav molecular siab dua tiv thaiv kev tso tawm los ntawm lub raum thiab ua rau muaj kev sib sau ua ke hauv lub cev. Piv txwv zoo tshaj plaws ntawm cov qauv povidone yog povidone-iodine, ib qho tshuaj tua kab mob tseem ceeb.
Dawb ntws, hmoov dawb, ruaj khov zoo, tsis khaus, yaj hauv dej thiab ethnol, muaj kev nyab xeeb duathiab yooj yim dua rau siv,. Zoo rau kev tua bacillus, cov kab mob & epiphytes. Sib xws nrog feem ntau ntawm qhov chaw.
Muaj nyob rau hauv cov dej ntws dawb, xim av liab, tsis khaus nrog kev ruaj khov zoo, yaj hauv dej thiab cawv, tsis yaj hauv diethylene thiab chloroform.

Feem ntau muaj cov polyvinylpyrrolidone ua hmoov los yog kua. PVP siv rau hauv cov tshuaj pleev ib ce, mousse, eruptions, thiab cov plaub hau, xim, luam ntawv number case, textile, luam ntawv thiab dyeing, cov raj duab xim siv tau ua cov neeg sawv cev rau txheej saum npoo, cov neeg sawv cev dispersing, thickeners, thiab binders. Hauv kev kho mob, feem ntau siv cov binders rau cov ntsiav tshuaj, granules thiab lwm yam.
