Hydroxypropyl Methylcellulose (HPMC) Lintlha
Hydroxypropyl Methylcellulose (HPMC)ke polymer e feto-fetohang le e sebelisoang haholo e tsoang ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. HPMC e hlahisoa ka phetoho ea lik'hemik'hale ea selulose ka propylene oxide le methyl chloride. Phetoho ena e fana ka thepa e ikhethang ho selulose, e etsa hore e qhibilihe ka metsing 'me e loketse lits'ebetso tse fapaneng. Lintlha tse mabapi le Hydroxypropyl Methylcellulose ke tsena:
- Sebopeho sa Lik'hemik'hale:
- HPMC e tšoauoa ka boteng ba hydroxypropyl le lihlopha tsa methyl sebopeho sa eona sa lik'hemik'hale.
- Ho eketsoa ha lihlopha tsena ho ntlafatsa ho qhibiliha le ho fetola thepa ea 'mele le ea lik'hemik'hale ea cellulose.
- Thepa ea Sebele:
- HPMC ka tlwaelo ke phofo e tshweu ho isa ho e tshweu hanyane e nang le sebopeho sa fibrous kapa granular.
- Ha e na monko ebile ha e latsoehe, e etsa hore e loketse ho sebelisoa lihlahisoa tseo thepa ena e leng ea bohlokoa.
- HPMC e qhibiliha ka metsing, e etsa tharollo e hlakileng le e se nang mebala.
- Degree ea Phapanyetsano:
- 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.
- Mephato e fapaneng ea HPMC e kanna ea ba le maemo a fapaneng a phapanyetso, e amang thepa le ts'ebeliso ea polymer.
- Lisebelisoa:
- Meriana: HPMC e sebelisoa haholo indastering ea meriana e le mothusi. E fumaneha ka mefuta ea litekanyetso tsa molomo joalo ka matlapa, li-capsules le li-suspension. E sebetsa e le setlamo se kopanyang, se arolang, le viscosity modifier.
- Indasteri ea Kaho: Lisebelisoa tsa kaho, HPMC e sebelisoa lihlahisoa tse kang likhomaretsi tsa lithaele, lirekere le lisebelisoa tse thehiloeng ho gypsum. E ntlafatsa ho sebetsa, ho boloka metsi, le ho khomarela.
- Indasteri ea Lijo: HPMC e sebetsa e le setenya, se tsitsisa, le emulsifier indastering ea lijo, e kenya letsoho ho sebopeho le botsitso ba lihlahisoa tsa lijo.
- Lihlahisoa tsa Tlhokomelo ea Motho: HPMC e sebelisoa lihlahisoa tsa litlolo le tsa tlhokomelo ea motho ka mong, ho kenyeletsoa litlolo, litlolo, le litlolo, bakeng sa thepa ea eona e teteaneng le ho tsitsisa.
- Mesebetsi:
- Tlhahiso ea Lifilimi: HPMC e na le bokhoni ba ho etsa lifilimi, e etsa hore e be ea bohlokoa lits'ebetsong tse kang liphahlo tsa letlapa indastering ea meriana.
- 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, HPMC e thusa ho boloka metsi, ho ntlafatsa ts'ebetso ka ho thibela ho omisa pele ho nako.
- Tšireletseho:
- HPMC ka kakaretso e nkuoa e bolokehile hore e ka sebelisoa litlhare, lijong le lihlahisoa tsa tlhokomelo ea motho ha e sebelisoa ho latela litataiso tse thehiloeng.
- Boemo ba polokeho bo ka fapana ho ipapisitsoe le lintlha tse joalo ka tekanyo ea phetoho le ts'ebeliso e ikhethileng.
Ka bokhutšoanyane, Hydroxypropyl Methylcellulose (HPMC) ke polymer e feto-fetohang e nang le ts'ebeliso ho tsa meriana, kaho, lijo le lihlahisoa tsa tlhokomelo ea motho. Thepa ea eona e ikhethang e etsa hore e be ea bohlokoa bakeng sa sebopeho sa lifilimi, phetoho ea viscosity, le ho boloka metsi ka mefuta e fapaneng ea liindasteri tse fapaneng.
