Iyini i-Polyvinylpyrrolidone PVP Series PVP K12 K15 K17 K25 K30 K60 K90?

Isixazululo sempushana noma esinamanzi, esincibilika emanzini, utshwala, i-amine nama-halogenated hydrocarbons, engancibiliki ku-acetone, i-ether, njll. Ine-solubility enhle kakhulu, i-biocompatibility, ukungabi namandla komzimba, ukwakheka kwefilimu, ikhono lokuvikela ulwelwesi kanye nekhono lokuhlanganisa izinhlobonhlobo zezinto eziphilayo kanye ama-inorganic compounds. Iqinile ku-asidi, usawoti kanye nokushisa, ngakho-ke inezinhlobonhlobo zokusetshenziswa.

Isicelo

I-Polyvinylpyrrolidone isetshenziswa kabanzi emkhakheni wezokwelapha futhi ingenye yezinto ezintathu ezintsha ezisizayo ezikhuthazwa emhlabeni jikelele. Amathebulethi asetshenziswa kakhulu amaphilisi nama-granules. Ingasetshenziswa futhi njengendlela yokusiza ukugeleza kwama-capsules, i-detoxification kanye ne-lubricant yezidakamizwa zamehlo, i-co-solvent yemijovo, i-disperant yamalungiselelo oketshezi, kanye ne-stabilizer yama-enzyme nezidakamizwa ezizwela ukushisa. I-Povidone ingabuye ihlanganiswe nesibulala-magciwane se-iodine povidone (PVP-I). Kumalensi okuxhumana, i-PVP isetshenziswa njengengxenye yamalensi okuxhumana ukuze kwandiswe i-hydrophilicity yawo. I-PVP ingasetshenziswa futhi njengesilondolozi se-cryogenic kwezokwelapha.
