Hydroxypropypropypropinyl methylcellfillose (HPMC) ke polymer e nkiloe le Celluddlese 'me ho sebelisoa hangata indasteri, litlolo, le lijo. Ke polymer ea qhibilihang ea metsi e ka fokotsang habonolo ho theha tharollo ea li-viscous.
1. Ho utloisisa HPMC:
Pele u bua ka mokhoa o hlakileng, ho bohlokoa ho utloisisa thepa ea HPMC. HPMC ke polymer ea maiketsetso ea semi-sydrotic, ho bolelang hore e na le moea o matla oa metsi. E etsa likoranta tse pepeneneng, e tenyetsehang le likhase tse tsitsitseng ha li ilwa ha li le hantle ha li ne li loketse likopo tse fapaneng.
2. Mokhoa oa ho hlaka:
HPTRARD ea HPMC e kenyelletsa ho hasanya phofo ea polymer ka metsing mme e e lumelle ho ruruha ho etsa tharollo ea li-viscous kapa gel. Mona ke tataiso ea mohato ka mohato ho hpdation hpmc:
Khetha sehlopha se nepahetseng:
HPMC e fumaneha ka limaraka tse fapaneng tse nang le boima ba liseleCalar le limaraka tsa pono. Khetho ea sehlopha se loketseng ho latela pono e lakatsehang ea tharollo ea ho qetela kapa gel. Boima ba molemi bo phahameng ba boima ba 'mele ka kakaretso bo baka litharollo tse phahameng tsa pono.
Lokisetsa metsi:
Sebelisa metsi a hloekisitsoeng kapa a halikiloeng bakeng sa hpmc ho netefatsa hore ho se be le liphoso tse ka amang thepa ea tharollo. Mocheso oa metsi o ka matlafatsa ts'ebetso ea toma. Ka kakaretso, ho sebelisa metsi a mocheso a kamore ho lekane, empa ho futhumatsa metsi hanyane ho atolosa mokhoa oa ho holisa maikutlo.
Ho se hloekisang:
Butle-butle fafatsa phofo ea HPMC ka metsing ha e ntse e tsitsipanya ho thibela sebopeho sa li-clumps. Ho bohlokoa ho kenyelletsa polymer butle butle ho netefatsa ho hasanya ha u hasaha le ho thibela ho alafatsoa.
HYDER:
Tsoela pele ho hlohlelletsa motsoako ho fihlela phofo eohle ea HPMC e hasana ka metsing. Lumella motsoako ho emela nako e lekaneng ho lumella likaroloana tsa polymer ho ruruha le ho imahala ka botlalo. Nako ea Рhali e ka fapana ho latela maemo a kang mocheso, molabe, molangoana le pono e lakatsehang.
Ho Kopanya le Ho Femogezation:
Kamora nako ea hydration, kopanya tharollo ka botlalo ho netefatsa ho tšoana. Ho latela ts'ebeliso, ho kopanya ho eketsehileng ho ka hlokahala ho fihlela mohopolo o lakatsehang ebe o tlosa likhama tse setseng.
Ho fetola PH le litlatsetso (haeba ho hlokahala):
Ho latela ts'ebeliso e itseng, ho ka hlokahala hore u fetole phallo ea tharollo e sebelisang acid kapa mesjese. Ho feta moo, ekeletsoa lits'oants'o tse ling joalo ka li-pressivel
Sefahi (haeba ho hlokahala):
Maemong a mang, haholo-holo likopo tsa meriana kapa litlolo, ho fafatsa tharollo ea 'mele ho ka hlokahala ho tlosa likaroloana leha e le life tse sa tsejoeng kapa tse tšoanang.
3. Likopo tsa HPMC:
HPMCC e fumana likopo tsa indasteri e fapaneng:
- Phapanyetsano ea pharmaceuta
- Indasteri ea litlolo: HPMC e sebelisoa hangata ho litloloko ka litlolo, litlolo le li-gels joalo ka molora oa bolotsana.
- indasteri ea lijo: Litumellano tsa lijo, hfulcc ea hydrate e sa tsoakoang
- Indasteri ea kaho: HPMC e sebelisoa ka lisebelisoa tsa kaho e kang ea lefutso, liloko le lik'hamphani tsa litoeba le ho boloka metsi.
4. Qeto:
HydroxypropypropypropinyL methylcelllulose (HPMC) ke polymer ea sa fetoheng e ka ntshoang habonolo ho theha tharollo ea li-vascous kapa li-gels. Ts'ebetso ea ho hloekisa e kenyelletsa phofo ea HPMC ka metsing, e e lumella ho ruruha, le ho kopanya ho fihlela phetoho e ts'oanang. HPMMC e fumana lits'ebetso indastering ea indasteri e fapaneng, ho kenyelletsa merafo, litlolo, lijo le kaho. Ho utloisisa ts'ebetso ea Hydration le thepa ea HPMC ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea eona likolong tse fapaneng.
