Hydroxypropypropypropypropinyl methylcellll HpMC E3, E5, E15, E15, E0M

Hydroxypropypropypropinyl methylcelllulose (HPMC) ke ether e nang le limaraka tse fapaneng, tse boletsoeng ke mangolo le linomoro. Mekha ena e emela litlhaloso tse fapaneng, ho kenyelletsa le phapang e fapaneng ea limolek'hule, tsa hydroxypropyl litsobotsi. Mona ke ho phatloha ha limaraka tsa HPMC tseo u li boletseng:

1. Hpmc e3:
   • Kereiti ena e bua ka HPMC e nang le litšoantšo tse khethehileng 2.4-3.6cps. Palo ea 3 e bontša pono ea tharollo ea leqhubu la 2%, 'me ka kakaretso lipalo tse ngata ka kakaretso li bontša pono e phahameng.
2. Hpmc e5:
   • E ts'oanang le E3, HPMC e5 e emela sehlopha se fapaneng sa pono. Palo ea 5 e bonts'a pono e lekanang ea pono ea 4.0-6,0 ea tharollo ea 2%.
3. Hpmc e6:
   • HPMC E6 ke sehlopha se seng se nang le profil e fapaneng ea liketsahalo. Nomoro ea 6 e supa pono ea viscosity 4.8-7.2 CPS ea tharollo ea 2%.
4. Hpmc e15:
   • HPMC E15 e kanna ea emela sehlopha se phahameng sa pono se bapisoang le E3, E5, kapa E6. Palo ea 15 e bontša viscosity 12.0-18.0cps tsa tharollo ea 2%, e fana ka maikutlo a ho feto-fetoha.
5. Hpmc e 9:
   • HPMC e50 e bonts'a sehlopha se phahameng sa pono, ka palo ea 50 e emelang Viscosity 40.0-60.0 CPS ea tharollo ea 2%. Kena ena e kanna ea ba le pono e phahameng haholo e bapisoang le E3, E5, E6, kapa E15.
6. HPMC E4M:
   • "M" e4m ka tloaelo e bolela liketsahalo tse mahareng 3200-4800cps. Hpmc e4m e emela sehlopha se nang le boemo bo leka-lekaneng ba pono. E kanna ea loketse likopo tse hlokang tekanyo lipakeng tsa phokotiki le botenya.

Ha u khetha sehlopha sa HPMC bakeng sa ts'ebeliso e itseng, ho nahanela ho shebella ha liketsahalo tse lakatsehang, tsa kutloano le litšobotsi tse ling tsa ts'ebetso. HPMC e sebelisoa hangata indasteri, meriana, litlolo, le lijo.

Ka lijo, hpmc hangata e sebelisoa e le lisebelisoa tse ngata tseo e seng tsa lebese tse kang ho boloka metsi, ho ba le liphetoho le ho ba le botshepehi. Litormaceuticals le litlolo, HPMC e sebelisetsoa thepa ea eona e etsang filimi le e tonang.

Ho bohlokoa ho buisana le moetsi kapa morekisi ho fumana tlhaiso-leseling e qaqileng ea mahlale, ho kenyelletsa litlhaloso le lits'ebeletso tse khothalletsoang bakeng sa sehlopha se seng le se seng sa HPMC. Baetsi ba lihlahisoa hangata ba fana ka maqephe a tlhaiso-leseling le litokomane tsa sehlahisoa ho tataisa basebelisi bakeng sa ho khetha sehlopha se loketseng litlhoko tsa bona tse nepahetseng.
