I-Povidone-K90 / PVP-K90 Ethengiswa Ngobuningi
Isingeniso:
| I-INCI | Ama-molecule |
| I-POVIDONE-K90 | ( C6H9NO )n |
I-Povidone (i-polyvinylpyrrolidone, i-PVP) isetshenziswa embonini yezemithi njengendlela yokwenza i-polymer yokuhlakaza nokumisa imithi. Inezindlela eziningi zokusebenzisa, okuhlanganisa njenge-binder yamaphilisi nama-capsule, ifilimu eyakhiwe yezixazululo zamehlo, ukusiza ekunambithekeni koketshezi namaphilisi ahlafunwayo, kanye ne-glue yezinhlelo ze-transdermal.
I-Povidone inefomula yama-molecule ka-(C6H9NO)n futhi ibonakala njengempuphu emhlophe kuya kwemhlophe kancane. Izinhlobo ze-Povidone zisetshenziswa kakhulu embonini yezemithi ngenxa yamandla azo okuncibilika kokubili emanzini kanye nasezithambisweni zamafutha. Inombolo ye-k ibhekisela esisindweni sama-molecule esimaphakathi se-povidone. Ama-Povidone anamanani aphezulu e-K (okungukuthi, k90) awavame ukunikezwa ngomjovo ngenxa yesisindo sawo esiphezulu sama-molecule. Isisindo sama-molecule aphezulu sivimbela ukuphuma kwezinso futhi siholele ekuqongeleleni emzimbeni. Isibonelo esaziwa kakhulu sezinhlobo ze-povidone yi-povidone-iodine, isibulala-magciwane esibalulekile.
Igeleza mahhala, i-powder emhlophe, izinzile kahle, ayicasuli, incibilika emanzini nase-ethnol, iphephilefuthi kulula ukuyisebenzisa,. Isebenza kahle ekubulaleni ama-bacillus, amagciwane kanye nama-epiphytes. Ihambisana neningi lezinto ezingaphandle.
Ikhona njengempuphu egeleza ngokukhululekile, enombala onsundu obomvu, engacasuli futhi izinzile kahle, incibilika emanzini nasetshwaleni, ayincibiliki ku-diethylethe kanye ne-chloroform.
Imininingwane

Iphakheji
25KGS ngekhadibhodi ngalinye
Isikhathi sokusebenza
Izinyanga ezingama-24
Isitoreji
Iminyaka emibili uma igcinwe ngaphansi kwezimo ezipholile nezomile futhi ivalwe kahle
I-Polyvinylpyrrolidone ivame ukuba ngesimo sempuphu noma isixazululo. I-PVP ezimonyweni zezimonyo, ukuqhuma, kanye nezinwele, upende, uyinki wokunyathelisa, indwangu, ukunyathelisa nokudaya, amashubhu ezithombe zombala angasetshenziswa njengezinto zokuhlanganisa ubuso, izinto zokusabalalisa, izinto zokuqinisa, izinto zokubopha. Kwezokwelapha, izihlanganisi ezisetshenziswa kakhulu zamaphilisi, ama-granule njalo njalo.
