Amathegi Omkhiqizo

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

Isixazululo sempuphu noma samanzi, esincibilikayo emanzini, utshwala, i-amine kanye nama-hydrocarbon angenawo uketshezi, esingancibiliki ku-acetone, i-ether, njll. Sinokuncibilika okuhle kakhulu, ukuhambisana kwezinto eziphilayo, ukungangeni komzimba, ukwakheka kwefilimu, ikhono lokuvikela ulwelwesi kanye nekhono lokuhlanganisa izinhlobo ezahlukene zamakhemikhali e-organic kanye ne-inorganic. Sizinzile ku-asidi, usawoti kanye nokushisa, ngakho-ke sinokusetshenziswa okubanzi.

Isicelo

I-Polyvinylpyrrolidone isetshenziswa kabanzi emkhakheni wezokwelapha futhi ingenye yezinto ezintathu ezintsha ezisetshenziswa emithini ezikhuthazwa emhlabeni jikelele. Izinamathiseli ezisetshenziswa kakhulu amaphilisi nama-granule. Ingasetshenziswa futhi njengosizo lokugeleza kwama-capsule, ukuhlanza umzimba kanye nokugcoba imithi yamehlo, isinyibilikisi esihlangene somjovo, isihlanzisi sokulungiselela uketshezi, kanye nesiqinisi sama-enzyme kanye nemithi ezwela ukushisa. I-Povidone ingaphinde yenziwe ngesibulali-magciwane se-iodine povidone iodine (PVP-I). Kuma-contact lens, i-PVP isetshenziswa njengengxenye yama-contact lens ukwandisa ukunamathela kwawo emanzini. I-PVP ingasetshenziswa futhi njengesivikelo se-cryogenic kwezokwelapha.
