Iarrtas

Tha polyvinylpyrrolidone air a chleachdadh gu farsaing ann an raon leigheis agus is e aon de na trì stuthan cungaidh-leigheis ùra a thathar a’ moladh gu h-eadar-nàiseanta. Is e clàran agus gràinneagan na adhesives as fharsainge. Faodar a chleachdadh cuideachd mar thaic sruthadh airson capsalan, detoxification agus bealaidh airson drogaichean sùla, co-solvent airson in-stealladh, inneal-sgaoilidh airson ullachadh leaghan, agus stàball airson enzyman agus drogaichean a tha mothachail air teas. Faodar Povidone a cho-chur cuideachd le inneal-dìona iodine povidone iodine (PVP-I). Ann an lionsan conaltraidh, tha PVP air a chleachdadh mar phàirt de lionsan conaltraidh gus an hydrophilicity àrdachadh. Faodar PVP a chleachdadh cuideachd mar ghleidheadair cryogenic ann an leigheas.
