HPMC e emetse Hydroxypropyl Methylcellulose, e leng ether e seng ionic cellulose e atisang ho sebelisoa liindastering tse fapaneng tse kang tsa meriana, kaho, lijo, litlolo le masela.Poleloana "HPMC grade" e bua ka litlhaloso tse fapaneng kapa limaraka tsa Hydroxypropyl Methylcellulose, tse ikemiselitseng ho ipapisitse le litekanyo tse fapaneng tse kenyelletsang boima ba limolek'hule, viscosity, degree ea substitution, le thepa e 'ngoe ea 'mele.Ho utloisisa limaraka tsa HPMC ho bohlokoa bakeng sa ho khetha mofuta o nepahetseng oa HPMC bakeng sa lits'ebetso tse ikhethileng.
1. Boima ba Limolek'hule le Viscosity:
Boima ba limolek'hule le viscosity ke likarolo tse peli tsa bohlokoa tse khethollang ts'ebetso ea HPMC lits'ebetsong tse fapaneng.Boima bo phahameng ba limolek'hule HPMC e atisa ho ba le viscosity e phahameng, e susumetsang thepa e kang thickening, sebopeho sa filimi, le ho boloka metsi.
Likarolo tse fapaneng tsa HPMC li khetholloa ho ipapisitsoe le boima ba limolek'hule le mefuta ea viscosity.Mohlala, limaraka tsa "viscosity" tse tlase li loketse lits'ebetso tse hlokang ho felisoa ka potlako, athe limaraka tse nang le viscosity e phahameng li ratoa bakeng sa lits'ebetso tse hlokang ho bolokoa ha metsi ho ntlafalitsoe le thepa e teteaneng.
2. Phapanyetsano ea Degree (DS):
Tekanyo ea sebaka sa HPMC e bua ka moo lihlopha tsa hydroxyl tse ketane ea cellulose li nkeloang sebaka ke lihlopha tsa hydroxypropyl le methyl.Paramethara ena e ama thepa e kang solubility, thermal gelation, le bokhoni ba ho etsa filimi.
Mephato ea HPMC e nang le li-degree tse fapaneng tsa substitution e fana ka mesebetsi e fapaneng.Li-degree tse phahameng tsa substitution li atisa ho ntlafatsa ho qhibiliha ha metsi le sebopeho sa filimi, e leng se etsang hore li tšoanelehe bakeng sa lits'ebetso tse kang litsamaiso tsa phepelo ea lithethefatsi le litlolo.
3. Boholo ba Karolo le Bohloeki:
Boholo ba likaroloana le bohloeki le tsona ke lintlha tsa bohlokoa ha ho aroloa limaraka tsa HPMC.Boholo ba likaroloana tse nyane hangata bo lebisa ho phatlalatseng hantle le ho ts'oana ha lintho tse entsoeng, ha maemo a phahameng a bohloeki a netefatsa botsitso le boleng.
Likarolo tse fapaneng tsa HPMC li ka hlalosoa ho ipapisitsoe le kabo ea boholo ba likaroloana le maemo a bohloeki, ho netefatsa ho lumellana le lits'ebetso tse ikhethileng tsa tlhahiso le litlhoko tsa ts'ebeliso ea ho qetela.
4. Tumellano ea Taolo:
Limaraka tsa HPMC le tsona li ka aroloa ho ipapisitsoe le ho latela melao le litlhoko tsa liindasteri tse fapaneng.Mohlala, HPMC ea boemo ba meriana e tlameha ho fihlela litekanyetso tse thata tse behiloeng ke ba boholong ho netefatsa polokeho, ts'ebetso le boleng mecheng ea litlhare.
Ho latela melao le litekanyetso tse ikhethileng, joalo ka tse boletsoeng ke li-pharmacopeia kapa mekhatlo ea polokeho ea lijo, ho bohlokoa bakeng sa ho khetha sehlopha se nepahetseng sa HPMC bakeng sa tšebeliso ea meriana, lihlahisoa tsa lijo le lits'ebetso tse ling.
5. Thepa e Khethehileng le Lisebelisoa:
Limaraka tse ling tsa HPMC li entsoe ka thepa e ikhethileng ho fihlela litlhoko tse ikhethileng tsa kopo.Mohlala, limaraka tsa HPMC tse nang le thepa e laoloang ea tokollo li sebelisoa mefuteng ea meriana ho lelefatsa tokollo ea lithethefatsi le ho ntlafatsa katleho ea kalafo.
Likarolo tse ling tse khethehileng tsa HPMC li ka fana ka likhomaretsi tse ntlafalitsoeng, taolo ea rheological, kapa ho hanyetsa mongobo, ho li etsa hore li tšoanelehe bakeng sa ho sebelisoa ka likhomaretsi, liphahlo le lisebelisoa tsa kaho.
6. Maikutlo a Tšebelisano le Tlhahiso:
Khetho ea sehlopha sa HPMC e susumetsoa ke ho lumellana le metsoako e meng le litlhoko tsa ho etsoa.Limaraka tse fapaneng tsa HPMC li ka sebelisana ka tsela e fapaneng le li-additives tse ling, li-solvents le maemo a ts'ebetso, tse amang ts'ebetso le botsitso ba sehlahisoa sa ho qetela.
Mehopolo ea sebopeho e joalo ka kutloelo-bohloko ea pH, botsitso ba mocheso, le ho tsamaellana le lits'ebetso tse ikhethileng tsa tlhahiso li bapala karolo ea bohlokoa ho khethollang boemo bo nepahetseng ba HPMC bakeng sa kopo e fanoeng.
7. Mabaka a Tikoloho le Moshoelella:
Ka mokhoa o ntseng o eketseha, menahano ea tikoloho le moshoelella e susumetsa khetho ea limaraka tsa HPMC.Baetsi ba ka etelletsa pele limaraka tse hlahisoang ho tsoa mehloling e ka nchafatsoang kapa tse nang le tšusumetso e fokolang ea tikoloho bophelong bohle ba bona.
Mekhoa e tsitsitseng ea ho fumana chelete, biodegradability, le ho sebelisoa hape e fetoha mekhoa ea bohlokoa ea ho khetha limaraka tsa HPMC, haholo liindasteri tse batlang ho fokotsa khase ea tsona le tšusumetso ea tikoloho.
8. Mekhoa ea 'Maraka le Boqapi:
Mmaraka oa HPMC o matla, ka lipatlisiso tse tsoelang pele le nts'etsopele ea nts'etsopele ea limaraka tse ncha le libopeho.Litloaelo tsa 'maraka tse joalo ka tlhoko ea lisebelisoa tsa li-label tse hloekileng, lihlahisoa tsa tlhaho, le li-excipients tse sebetsang li susumetsa nts'etsopele ea limaraka tse ncha tsa HPMC ka thepa le ts'ebetso e ntlafalitsoeng.
Baetsi ba lula ba loanela ho fihlela litlhoko tse ntseng li fetoha tsa bareki le litlhoko tsa 'maraka ka ho hlahisa limaraka tse ncha tsa HPMC tse etselitsoeng lits'ebetso tse ikhethileng le mekhoa e hlahang, joalo ka mefuta e meng e thehiloeng limela, ho paka ka mokhoa o tsitsitseng, le litsamaiso tse tsoetseng pele tsa phano ea lithethefatsi.
Qetello:
Boima ba limolek'hule, viscosity, degree ea substitution, boholo ba likaroloana, bohloeki, ho lumellana le taolo, thepa e khethehileng, ho lumellana le maemo a tikoloho ke lintlha tsa bohlokoa ha u khetha sehlopha se nepahetseng sa HPMC.
Ho utloisisa limaraka tsa HPMC ho bohlokoa bakeng sa baetsi ba lihlahisoa, bafuputsi le bahlahisi ba batlang ho ntlafatsa ts'ebetso ea sehlahisoa, ho fihlela litlhoko tsa taolo, le ho rarolla mekhoa e tsoelang pele ea mmaraka.Ka ho lekola ka hloko thepa e ikhethang le bokhoni ba limaraka tse fapaneng tsa HPMC, bankakarolo ba ka etsa liqeto tse nang le tsebo ho fihlela sephetho se lakatsehang indastering le lits'ebetsong tsa bona.
