Ho netefatsa boleng ba hydroxypropyl methylcellulose (HPMC) ho kenyelletsa mekhoa e matla ea tlhahlobo maemong a fapaneng a tlhahiso.Mona ke kakaretso ea mekhoa e tloaelehileng ea tlhahlobo e sebelisoang ke baetsi ba HPMC:
Tlhahlobo ea Raw Material:
Liteko tsa Boitsebiso: Baetsi ba sebelisa mekhoa e kang FTIR (Furier Transform Infrared Spectroscopy) le NMR (Nuclear Magnetic Resonance) ho netefatsa boitsebiso ba lisebelisoa tse tala.
Tekolo ea Bohloeki: Mekhoa e kang HPLC (High-Performance Liquid Chromatography) e sebelisoa ho fumana bohloeki ba lisebelisoa tse tala, ho netefatsa hore li finyella litekanyetso tse boletsoeng.
Teko e ntseng e tsoela pele:
Tekanyo ea Viscosity: Viscosity ke paramente ea bohlokoa bakeng sa HPMC, 'me e lekantsoe ho sebelisoa li-viscometer methating e fapaneng ea tlhahiso ho netefatsa botsitso.
Tlhahlobo ea Mongobo: Likahare tsa mongobo li ama thepa ea HPMC.Mekhoa e kang ea Karl Fischer titration e sebelisoa ho fumana maemo a mongobo.
Tlhahlobo ea Boholo ba Particle: Mekhoa e joalo ka laser diffraction e sebelisoa ho netefatsa kabo ea boholo ba likaroloana, e leng bohlokoa bakeng sa ts'ebetso ea sehlahisoa.
Teko ea Taolo ea Boleng:
Tlhahlobo ea Lik'hemik'hale: HPMC e etsa tlhahlobo ea lik'hemik'hale bakeng sa litšila, metsoako e setseng, le litšila tse ling ho sebelisa mekhoa e kang GC-MS (Gas Chromatography-Mass Spectrometry) le ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy).
Tekolo ea Thepa ea 'Mele: Liteko tse kenyelletsang phallo ea phofshoana, bongata ba bongata, le ho hatelloa ho netefatsa hore litšoaneleho tsa 'mele tsa HPMC li kopana le litlhaloso.
Teko ea Microbiological: Tšoaetso ea likokoana-hloko ke taba e tšoenyang HPMC ea boemo ba meriana.Liteko tsa ho baloa ha likokoana-hloko le liteko tsa boitsebahatso ba likokoana-hloko lia etsoa ho netefatsa polokeho ea sehlahisoa.
Teko ea Ts'ebetso:
Lithuto tsa Phallo ea Lithethefatsi: Bakeng sa lits'ebetso tsa meriana, tlhahlobo ea ho qhibiliha e etsoa ho lekola ho lokolloa ha metsoako e sebetsang ho tsoa mefuteng e thehiloeng ho HPMC.
Thepa ea Tlhahiso ea Lifilimi: HPMC e sebelisoa hangata lifiliming, 'me liteko tse kang ho lekanya matla a thata li lekola litšobotsi tsa sebopeho sa filimi.
Teko ea Botsitso:
Lithuto tse Potlakileng tsa Botsofali: Teko ea botsitso e kenyelletsa ho beha lisampole tsa HPMC maemong a fapaneng a khatello ea maikutlo joalo ka mocheso le mongobo ho lekola bophelo ba sethala le kinetics ea ho senyeha.
Teko ea Botšepehi ba ho Koala Lits'oants'o: Bakeng sa lihlahisoa tse pakiloeng, liteko tsa bots'epehi li netefatsa hore lijana li sireletsa HPMC ka nepo ho tsoa linthong tsa tikoloho.
Tumellano ea Taolo:
Maemo a Pharmacopeial: Baetsi ba khomarela litekanyetso tsa meriana tse kang USP (United States Pharmacopeia) le EP (European Pharmacopoeia) ho finyella litlhoko tsa taolo.
Litokomane le ho Boloka Litlaleho: Litokomane tse qaqileng tsa mekhoa ea tlhahlobo, liphetho, le mehato ea tiisetso ea boleng li bolokiloe ho bontša ho lumellana le litekanyetso tsa taolo.
Baetsi ba sebelisa mekhoa e mengata ea tlhahlobo e kenyelletsang tlhahlobo ea thepa e tala, tlhahlobo ea ts'ebetso, taolo ea boleng, tlhahlobo ea ts'ebetso, tlhahlobo ea botsitso, le ho latela melao ho netefatsa boleng le polokeho ea lihlahisoa tsa hydroxypropyl methylcellulose.Liprothokholo tsena tsa liteko tse thata li bohlokoa bakeng sa ho boloka botsitso le ho fihlela litlhoko tse fapaneng tsa liindasteri tse kang tsa meriana, lijo, litlolo le kaho.
