Kugwiritsa ntchito

Polyvinylpyrrolidone imagwiritsidwa ntchito kwambiri pazamankhwala ndipo ndi imodzi mwazinthu zitatu zatsopano zothandizira mankhwala zomwe zimalimbikitsidwa padziko lonse lapansi.Zomatira zomwe zimagwiritsidwa ntchito kwambiri ndi mapiritsi ndi ma granules.Itha kugwiritsidwanso ntchito ngati njira yoperekera makapisozi, detoxification ndi lubricant pamankhwala am'maso, chosungunulira cha jekeseni, dispersant pokonzekera zamadzimadzi, komanso stabilizer ya michere ndi mankhwala osamva kutentha.Povidone amathanso kupangidwa ndi ayodini povidone ayodini (PVP-I) mankhwala ophera tizilombo.Mu magalasi olumikizana, PVP imagwiritsidwa ntchito ngati gawo la magalasi olumikizirana kuti awonjezere hydrophilicity yawo.PVP itha kugwiritsidwanso ntchito ngati cryogenic preservative muzamankhwala.
