Litaba tsa hydroxypropyLe methylcelllulose (HPMC) e itšetlehile ka lintlha tse fapaneng tse itšetlehileng ka lintlha tse fapaneng tse joalo ka khatello ea maikutlo, mocheso, boima ba molemi le sekhahla.
1.introduduction ea HPMC:
Hydroxypropypropypropinyl Methylcelllulose (HPMC) ke selefounu e seng ioni ea ionic ether E tloaelehile indastering e fapaneng e kang merimaceutucal, kaho le litlolo tsa eona ka lebaka la thepa ea eona e ikhethang. HPMC e qhibiliha ka metsing le li-solvent tse ling tsa manyolo, li etsa tharollo e hlakileng le e seng mebala.
2.Polip ea HPMC:
Meriana: Liphoto tsa Pharmaceutical, HPMC e sebelisoa haholo e le moemeli oa tokiso e laoloang, li-capcos
Kaho: HPMC e sebetsa e le moemeli ea tona, 'me Rheology Morifier ka lisebelisoa tse thehiloeng ho meeli, joalo ka litlolo, ho ntlafatsa le ho ntlafatsa ts'ebetso.
Indasteri ea lijo: HpMC e sebelisoa e le thipa, letheka, le emumolier lihlahisoa tsa lijo, ho kenyelletsa le li-soups, sosserts.
Li-cosmetics: Litsela, HPM e sebetsa joaloka boloi, e leng filimi le ho hlapanya lihlahisoa tse kang litlolo tse kang litlolo tse tšoanang le li-shampoos, le gels.
3.Fotandtors tse amang pono ea tharollo ea HPMC:
TLHOKOMELISO: Viscosity ea tharollo ea HPMC ka kakaretso e eketseha ka meaho e phahameng ea polymer ka lebaka la ho kena ka liketane pakeng tsa chinese.
Mocheso: Viscostory e fokotseha ka mocheso o ntseng o eketseha ka lebaka la ho sebelisana le mekhahlelo ea lintho tse fapaneng, e lebisang ho se ke sa sisinyeha hantle le tharollo e tlase ea "viscosity
Boima ba Molecular: Li-polymer tse phahameng tsa limolek'hule tsa HPMC li bonts'a Viscosity e phahameng ka lebaka la ho eketseha ha ketane ea tšepe le liketane tsa polymer.
Shear Profil: HpMC Tharollo hangata e bonts'a boitšoaro bo bobe, moo Viscosion e fokotsehileng ka maemo a phahameng ka lebaka la ho hokahanya ha methapo ea polymer.
4.Methos bakeng sa ho lekanya Viscosity:
Brookfield PRONPRATION FORTIVER: Liteko tse rekisoang bakeng sa torque ho tsekisanoang tharollong ea HPMC.
Rheometer: The Lekhotla le lekanyang thepa ea ho phalla ka litekanyetso tsa HPMC tlasa litheko tse laoloang kapa tsa khatello ea maikutlo.
Mechini e ntle ea capillary: mokhoa ona o kenyelletsa ho lekanya phepelo ea matlalo a HPMC ka matla a khoheli kapa khatello ea maikutlo.
5.Sosifified ea liketsahalo tsa indasteri e fapaneng:
Meriana: Liphookolong tsa pharmaceutaric
Kaho: Viscosity ea litlatsetso tse nepahetseng tsa lisebelisoa tsa HPMMC ho netefatsa hore ho na le bonnete ba ho tsitsipana, le ho tšoarella.
Indasteri ea lijo: Ho etsa lintho tse qaqileng ka sebopeho, botsitso le melomong ea maikutlo a lihlahisoa tsa lijo tse kang botenya, boriba le ho kokobela.
Li-cosmetics: Ho laola lifate ho bohlokoa bakeng sa ho theha litlolo tse kang thepa e lakatsehang, le ho khomarela letlalo kapa meriana.
Litsi tsa Tlhaho tsa HPMC li susumetsoa ke lintlha tse fapaneng ho kenyelletsa khatello, mocheso, boima ba molek'hale, le sekhahla sa methapo. Tekalo e nepahetseng ea Viscosion e bohlokoa bakeng sa ho netefatsa boleng ba sehlahisoa, ts'ebetso le maemo a ho feto-fetoha ha indastering e fapaneng. Ho utloisisa boits'oaro ba rheological of Hpmc ke ea bohlokoa bakeng sa lihlahisoa tse qalang ka thepa le ts'ebetso ea phallo e lakatsehang le ts'ebetso ea ts'ebetso. Joaloka lipatlisiso le nts'etsopele ea saense ea Polymer li ntse li tsoela pele ho tsoela pele ka har'a likopo tse fapaneng, ho tloha ho phaello ho ea mosebetsing le ho feta.
