HydropxpropypropyLe Methyl Mathata a Amohileng

HydroxypropypropyLese (HPMC)Ke polymer ea feto-fetohang a fumanang likopo tsa indasteri e fapaneng e kang merimacEonetucas, litlolo, lijo le kaho. Leha e le lits'ebeliso tse fapaneng tse fapaneng, ho na le mathata a 'maloa a amanang le HPMC hore basebelisi ba ka kopana.

Fulubility ea mafutsana: bothata bo le bong le hpmc ke sleng e futsanehileng ka metsing a batang. Sena se ka baka mathata ha ho theha lithaballo, haholo ha ho hlokahala delpture e tsitsitseng kapele. Ho hlola bothata bona, maano a mang a kenyelletsa hydration ea pele, a sebelisa metsi a futhumetseng, kapa ho sebelisa li-solvent tsa colouliking, kapa li sebelisa li-solvent tsa cute ho ntlafatsa linyeeletsing.

Lintho tse fetolang: Likelello tsa HPMC li ka fapana ka lebaka la maemo a kang mocheso, PH, sekhahla. Lintho tse sa lumellaneng li ka ama ts'ebetso ea liforomo, e lebisang litabeng tse joalo ka boleng bo bobe ba sehlahisoa kapa ho lokolloa ha lithethefatsi liprofeteng tsa meriana. Baetsi ba hloka ho laola maemo a taolo ka hloko ho fokotsa maemo a ho feto-fetoha le maemo a liketsahalo.

Tlhaho ea Hygroscopic: HPMC e tloaetse ho monya mongobo tikolohong, e ka amang thepa ea eona ea ho phalla le ho etsa hore li-caking kapa li be li-cuted. Ho fokotsa bothata bona, maemo a nepahetseng a polokelo, a joalo ka tikoloho e tlase ea mahlomola le bopaki ba boea ba mongobo, ba bohlokoa.

Boitšoaro: Lihlopheng tse ling, HPMC li ka bontša boitšoaro bo botle, haholo-holo meahong e phahameng kapa ka pel'a boteng ba li-ions tse itseng. Le ha ho sisinyeha ho ka bakoa ke lits'ebeliso tse kang tsa ho tsamaisa lithethefatsi tse bolokiloeng, ho ka boetse hoa lebisa ho ho sebetsana le mathata kapa sebopeho se sa rateheng lihlahisoa tse ling. Ho utloisisa lintlha tse ka khothatsang tsa gel ho bohlokoa bakeng sa ho laola ts'ebetso ea sehlahisoa.

Litaba tse lumellanang: HPMC e kanna ea se ke ea lumellana le metsoako e itseng kapa lisebelisoa tse tloaelehileng tse sebelisoang hangata ho liforomo. Ho se lumellane ho ka bonahatsa karohano ea dese, pula, kapa liphetoho tsa Viscosity, tse ka sekisetsa botsitso le katleho ea sehlahisoa. Ho hlahlojoa ha tlhahlobo ho lokela ho etsoa ho khetholla le ho sebetsana le litaba tse ka bang teng nakong ea ts'ebetso ea sebopeho.

Shear khang: hpmc tharollo hangata e bonts'a boitšoaro bo bobe, ho bolelang hore litšoantšiso tsa bona li fokotseha tlas'a khatello ea kelello. Le ha thepa ena e ka ba molemo bakeng sa lits'ebetso tse kang hore na ho na le mathata nakong ea ts'ebetso kapa ts'ebeliso, litsamaisong tse hlokang pono e tšoanang. Lintho tse nepahetseng tsa Rheologeni tse bohlokoa li bohlokoa bakeng sa ts'ebetso ea foromo ea ho theha.

Boitšoaro bo futhumetseng: Mocheso o phahameng o ka etsa hore khaello ea botlokotse e mpe ea HPMC, e lebisang ho viscosity, e fetoha ka boima ba limoleke, kapa sebopeho sa lihlahisoa tsa moleng. Ho tsitsa mocheso ke ho hlahlobisisa ts'ebetso le polokelo, 'me thepa ea lihlahisoa li tlameha ho laola ho nyenyefatsa mocheso ho fokotsa litšila le ho boloka boleng ba sehlahisoa.

Khokahano ea taolo: Ho latela ts'ebeliso e reriloeng le sebaka sa HPMC e ka ba tlasa litlhoko le litekanyetso tse laoloang, bohloeki le ho ngola. Ho netefatsa hore ho latela melao e loketseng ho bohlokoa ho amoheloa mabenkeleng le ho latela molao.

Ha a ntse ahydroxypropypropinyl methylcelle fana ka melemo e mengata e le polymer ea tlhaho, basebelisi ba ka kopana le mathata a fapaneng a amanang le alloubity, ho tsitsipana le ho ikatisa. Ho sebetsana le mathata ana a tloaelehileng ho hloka kutloisiso e nepahetseng ea thepa ea Polytrier
