Lintlha tse 5 tsa bohlokoa ka HPMC
Lintlha tse hlano tsa bohlokoa ka Hydroxypropyl Methylcellulose (HPMC) ke tsena:
- Sebopeho sa Lik'hemik'hale: HPMC ke polymer ea semi-synthetic e nkiloeng ho selulose, polysaccharide ea tlhaho e fumanoang limela. E hlahisoa ke cellulose e fetolang lik'hemik'hale ka ho eketsoa ha propylene oxide le methyl chloride. Polymer e hlahisoang e na le lihlopha tsa hydroxypropyl le methyl tse khomaretsoeng mokokotlong oa cellulose.
- Ho qhibiliha ha Metsi: HPMC e qhibiliha ka metsing 'me e etsa litharollo tse bonaletsang, tse nang le mahlo ha li kopane le metsi. Ho qhibiliha ha eona ho fapana ho itšetlehile ka lintlha tse kang boima ba limolek'hule, tekanyo ea ho fetola, le mocheso. HPMC e qhibiliha metsing a batang le a chesang, empa mocheso o phahameng ka kakaretso o potlakisa ho qhibiliha.
- Likopo tse fapaneng: HPMC e na le mefuta e mengata ea lits'ebetso ho liindasteri tse fapaneng. Indastering ea meriana, e sebelisoa e le se tlamellang, sa pele sa filimi, se teteaneng, le se sa khaotseng ho lokolloa matlapeng, li-capsules le li-topical formulations. Indastering ea lijo, e sebetsa e le setei, se tsitsitseng, le emulsifier lihlahisoa tse kang li-sauces, li-dressings le li-dessert. HPMC e boetse e sebelisoa ho litlolo, lihlahisoa tsa tlhokomelo ea motho, lisebelisoa tsa kaho le lits'ebetsong tsa indasteri.
- Thepa le Ts'ebetso: HPMC e bonts'a thepa e 'maloa e lakatsehang, ho kenyeletsoa bokhoni ba ho etsa lifilimi, ho futhumatsa mocheso, ho khomarela le ho boloka mongobo. E ka fetola thepa ea rheological ea litharollo le ho ntlafatsa sebopeho, botsitso, le ho tsitsisa mekhoeng e fapaneng. HPMC e boetse e sebetsa joalo ka polymer ea hydrophilic, e matlafatsang ho bolokoa ha metsi le hydration lihlahisoa tsa meriana le tsa litlolo.
- Mephato le Litlhaloso: HPMC e fumaneha ka limaraka le litlhaloso tse fapaneng ho fihlela litlhoko tse ikhethang tsa lits'ebetso tse fapaneng. Tsena li kenyelletsa phapang ea viscosity, boholo ba likaroloana, tekanyo ea ho fetola, le boima ba limolek'hule. Khetho ea sehlopha sa HPMC e itšetlehile ka lintlha tse kang viscosity e lakatsehang, solubility, thepa ea ho etsa filimi, le ho lumellana le lisebelisoa tse ling ha ho etsoa.
Lintlha tsena tsa bohlokoa li totobatsa bohlokoa le ho feto-fetoha ha HPMC joalo ka polymer e sebetsang ka bongata e nang le lits'ebetso tse pharalletseng liindastering tse kang tsa meriana, lijo, litlolo, kaho, le tse ling.
