Hydroxypropyl Methylcellulose Boitsebiso
Hydroxypropyl methylcellulose(HPMC) ke polymer e feto-fetohang le e sebelisoang haholo e nang le ts'ebeliso liindastering tse fapaneng, ho kenyeletsoa meriana, kaho, lijo le litlolo. Mona ke lintlha tse qaqileng mabapi le Hydroxypropyl Methylcellulose:
- Sebopeho sa Lik'hemik'hale:
- HPMC e tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.
- E etsa phetoho ea lik'hemik'hale ka propylene oxide le methyl chloride, e lebisang ho kenyelletsoeng ha hydroxypropyl le lihlopha tsa methyl mohahong oa cellulose.
- Thepa ea Sebele:
- Ka tloaelo ke phofo e tšoeu ho isa ho e mosoeu ka sebopeho sa fibrous kapa granular.
- Ha e na monko ebile ha e latsoehe.
- E qhibiliha ka metsing, ho etsa tharollo e hlakileng le e se nang mebala.
- Lisebelisoa:
- Meriana: E sebelisoa e le mothusi matlapeng, li-capsules le li-suspension. E sebetsa joalo ka binder, disintegrant, viscosity modifier, le filimi ea pele.
- Indasteri ea Kaho: E fumanoa lihlahisoa tse kang likhomaretsi tsa lithaele, lirekere le lisebelisoa tse thehiloeng ho gypsum. E matlafatsa ts'ebetso, ho boloka metsi, le ho khomarela.
- Indasteri ea Lijo: E sebetsa e le setenya, se tsitsisa, le ho etsa emulsifier lihlahisoa tse fapa-fapaneng tsa lijo, e tlatsetsang sebopeho le botsitso.
- Litlolo le Lihlahisoa tsa Tlhokomelo ea Motho: E sebelisoa ka litlolo, litlolo, le litlolo bakeng sa ho tiisa le ho tsitsisa.
- Mesebetsi:
- Tlhahiso ea Lifilimi: HPMC e ka etsa lifilimi, ea etsa hore e be ea bohlokoa lits'ebetsong tse kang liphahlo tsa letlapa le litlolo tsa litlolo.
- Viscosity Modification: E fetola viscosity ea tharollo, e fana ka taolo holim'a thepa ea rheological ea metsoako.
- Poloko ea Metsi: E sebelisoa linthong tsa kaho ho boloka metsi, ho ntlafatsa ts'ebetso, le litlolong tsa litlolo ho matlafatsa ho boloka mongobo.
- Mekhahlelo ea ho fetola:
- Tekanyo ea ho nka sebaka e bolela palo e tloaelehileng ea lihlopha tsa hydroxypropyl le methyl tse kenyellelitsoeng yuniti e 'ngoe le e 'ngoe ea tsoekere ka har'a ketane ea cellulose.
- Likarolo tse fapaneng tsa HPMC li kanna tsa ba le likhato tse fapaneng tsa phetoho, tse amang thepa joalo ka ho qhibiliha le ho boloka metsi.
- Tšireletseho:
- Ka kakaretso e nkoa e sireletsehile bakeng sa tšebeliso ea meriana, lijo, le lihlahisoa tsa tlhokomelo ea botho ha li sebelisoa ho latela litataiso tse behiloeng.
- Mehopolo ea polokeho e ka ipapisa le lintlha tse joalo ka tekanyo ea phetoho le ts'ebeliso e ikhethileng.
Ka kakaretso, Hydroxypropyl Methylcellulose (HPMC) ke polymer e sebetsang ka bongata e sebelisoang haholo bakeng sa thepa ea eona e ikhethang liindastering tse fapaneng. Ho qhibiliha ha eona metsing, bokhoni ba ho etsa lifilimi, le ho feto-fetoha ha maemo ho etsa hore e be motsoako oa bohlokoa litlhare, thepa ea kaho, lihlahisoa tsa lijo le litlolo. Kereiti e ikhethileng le litšobotsi tsa HPMC li ka hlophisoa ho fihlela litlhoko tsa lits'ebetso tse fapaneng.
