Hydroxypropylmethylcellulose (HPMC) ke motsoako o sebelisoang haholo o nang le mefuta e mengata ea lits'ebetso tsa indasteri, tsa khoebo le tsa bophelo bo botle.HPMC ke motsoako o sa nkheng, o sa latsoeheng, le o se nang chefo o tsoang ho selulose.Ke motsoako o qhibilihang ka metsing o sebelisoang mefuteng ea lijo, litlolo, lithethefatsi le meriana.HPMC e tsebahala ka bokhoni ba eona bo botle ba ho etsa lifilimi, thepa ea sekhomaretsi le matla a ho boloka metsi.E boetse e tsejoa ka viscosity ea eona e babatsehang, botsitso le ho lumellana le mefuta e sa tšoaneng ea lintho.
Mefuta ea HPMC:
Ho na le mefuta e 'maloa ea HPMC' marakeng, e 'ngoe le e' ngoe e na le thepa e ikhethang ea 'mele le ea lik'hemik'hale.Mefuta e meng e tloaelehileng ea HPMC ke ena:
1. HPMC ea viscosity e tlase:
Low viscosity HPMC e tšoauoa ka tlaase boima ba molek'hule le tekanyo e tlaase ea ho nka sebaka.Ka lebaka la thepa ea eona e babatsehang ea ho tlama, hangata e sebelisoa e le setlamo le ho senya matlapeng.
2. Viscosity e mahareng HPMC:
Mahareng viscosity HPMC na le mahareng boima ba molek'hule le tekanyo ea ho nka sebaka.Hangata e sebelisoa ho tsitsisa emulsions, suspensions le foams indastering ea lijo le lino.
3. High viscosity HPMC:
Phahameng viscosity HPMC tšoauoa ka phahameng molek'hule boima le tekanyo e phahameng ea ho fetola.E atisa ho sebelisoa e le ntho e teteaneng le ea gelling indastering ea lijo le ea litlolo.
4. Phekolo ea sefahleho HPMC:
Surface treatment HPMC e alafshoa ka lik'hemik'hale tse fapaneng ho fetola boleng ba eona.Hangata e sebelisoa e le tlatsetso indastering ea kaho ho ntlafatsa thepa ea thepa e thehiloeng ho samente.
Melemo ea HPMC:
HPMC e tlisa melemo e mengata ho liindasteri tse fapaneng.Mona ke melemo e meng ea HPMC:
1. E bolokehile ebile ha e na chefo:
E 'ngoe ea melemo e ka sehloohong ea HPMC ke polokeho ea eona le ho se chefo.HPMC e tsoa ho cellulose, motsoako oa tlhaho.Hape ha e halefise letlalo, mahlo le lera la mucous, e leng se etsang hore e be motsoako o sireletsehileng lihlahisoa tse fapaneng.
2. Ho qhibiliha ha metsi:
HPMC e qhibiliha haholo ka metsi, e e etsa motsoako o babatsehang bakeng sa lihlahisoa tse fapaneng tse hlokang ho boloka metsi le ho khomarela.E sebelisoa hangata joalo ka setlamo le sekoahelo indastering ea lijo le ea meriana.
3. Bokhoni ba ho etsa lifilimi:
HPMC e na le bokhoni bo botle ba ho etsa lifilimi, e etsa hore e be motsoako o babatsehang bakeng sa lihlahisoa tse fapa-fapaneng tse hlokang litlolo tse sireletsang.Hangata e sebelisoa indastering ea meriana bakeng sa ho roala matlapa le li-capsules.
4. Viscosity le thickening thepa:
HPMC e na le viscosity e babatsehang le thepa e teteaneng, e etsang hore e be motsoako o babatsehang bakeng sa lihlahisoa tse fapaneng tse hlokang sebopeho se teteaneng, se boreleli.E sebelisoa hangata indastering ea lijo le ea litlolo ho tenya lisoso le litlolo.
5. Ho tsitsa le ho lumellana:
HPMC e na le botsitso bo babatsehang le ho lumellana le lintho tse fapa-fapaneng, ho etsa hore e be motsoako o babatsehang lihlahisoa tse fapaneng tse hlokang botsitso le ho lumellana.Hangata e sebelisoa indastering ea meriana ho tsitsisa metsoako ea lithethefatsi.
HPMC ke motsoako o sebetsang ka bongata o tlisang melemo e mengata ho liindasteri tse fapaneng ho kenyelletsa lijo, litlolo le meriana.Thepa ea eona e ikhethang ea 'mele le ea lik'hemik'hale e etsa hore e be motsoako o babatsehang oa lihlahisoa tse fapa-fapaneng, tse kenyelletsang li-binders, disintegrants, emulsion, li-suspending agents, foams, thickeners, gelling agents, le baetsi ba lifilimi.HPMC e boetse e bolokehile ebile ha e na chefo, e etsa hore e be motsoako o babatsehang lihlahisoa tse fapaneng tse hlokang tšireletso le ho se chefo.Mefuta e fapaneng ea HPMC e fumanehang 'marakeng e fana ka liindasteri tse fapaneng ka likhetho tse fapaneng tseo u ka khethang ho tsona ho latela litlhoko le litlhoko tsa bona.
