(Hydroxypropyl) methyl cellulose
(Hydroxypropyl) methyl cellulose, eo hangata e tsejoang e le Hypromellose kapa HPMC, ke polymer ea semi-synthetic e nkiloeng ho cellulose, polima ea tlhaho e fumanoang marakong a lisele tsa semela. Lebitso la lik'hemik'hale le bonts'a tlatsetso ea lihlopha tsa hydroxypropyl le methyl ho selulose ka ts'ebetso ea phetoho ea lik'hemik'hale. Phetoho ena e ntlafatsa thepa ea polymer, e etsa hore e sebelisoe liindastering tse fapaneng. Mona ke kakaretso:
- Sebopeho sa Lik'hemik'hale:
- Lentsoe "(Hydroxypropyl) methyl cellulose" le bolela boteng ba lihlopha tsa hydroxypropyl le methyl sebopeho sa lik'hemik'hale tsa selulose.
- Ho eketsoa ha lihlopha tsena ho fetola thepa ea 'mele le ea lik'hemik'hale ea selulose, e hlahisang polymer e fetotsoeng.
- Thepa ea Sebele:
- Ka tloaelo, Hypromellose ke phofo e tšoeu ho isa ho e bosoeu hanyenyane e nang le sebopeho sa fibrous kapa granular.
- Ha e na monko ebile ha e latsoehe, e kenya letsoho ho lokeleng ha eona ho sebelisoa lits'ebetsong tse fapaneng.
- Polymer e qhibiliha ka metsing, e etsa tharollo e hlakileng le e se nang 'mala.
- Lisebelisoa:
- Litlhare: Hypromellose e sebelisoa haholo indastering ea meriana e le karolo ea thuso ka mefuta e fapaneng ea litekanyetso tsa molomo. E sebetsa ka likarolo tse joalo ka setlamo, disintegrant, le viscosity modifier matlapeng, li-capsules le li-suspensions.
- Indasteri ea Kaho: Linthong tsa kaho, Hypromellose e sebelisoa lihlahisoa tse kang likhomaretsi tsa lithaele, lirekere le lisebelisoa tse thehiloeng ho gypsum. E ntlafatsa ts'ebetso, ho boloka metsi, le ho khomarela.
- Indasteri ea Lijo: E sebetsa e le setei, se tsitsitseng, le emulsifier indastering ea lijo, e ntlafatsa sebopeho le botsitso ba lihlahisoa tsa lijo.
- Lihlahisoa tsa Tlhokomelo ea Motho: Hypromellose e fumanoa lihlahisoa tsa litlolo le tsa botho tse kang lotions, litlolo le mafura ka lebaka la thepa ea eona e teteaneng le e tsitsitseng.
- Mesebetsi:
- Tlhahiso ea Lifilimi: Hypromellose e na le bokhoni ba ho etsa lifilimi, e leng ea bohlokoa ka ho khetheha lits'ebetsong tsa meriana tse kang ho roala letlapa.
- Phetoho ea Viscosity: E ka fetola viscosity ea tharollo, e fana ka taolo holim'a thepa ea rheological ea metsoako.
- Ho boloka Metsi: Linthong tsa kaho, Hypromellose e thusa ho boloka metsi, ho ntlafatsa ts'ebetso le ho thibela ho omisa pele ho nako.
- 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) methyl cellulose (Hypromellose kapa HPMC) ke motsoako o feto-fetohang le o sebelisoang haholo o nang le ts'ebeliso ea meriana, kaho, lijo le tlhokomelo ea motho. Phetoho ea eona ea lik'hemik'hale e ntlafatsa ho qhibiliha ha eona le ho fana ka ts'ebetso e ikhethang, e etsa hore e be motsoako oa bohlokoa lihlahisoa tse fapaneng liindastering tse fapaneng.
