Hydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

Hydroxypropyl Methylcellulose (HPMC) ke ether ea cellulose e nang le limaraka tse fapaneng, tse bontšitsoeng ka litlhaku le linomoro. Limaraka tsena li emela litlhaloso tse fapaneng, ho kenyeletsoa le mefuta e fapaneng ea boima ba limolek'hule, litaba tsa hydroxypropyl le viscosity. Mona ke tlhaloso ea limaraka tsa HPMC tseo u li boletseng:

1. HPMC E3:
   • Sehlopha sena mohlomong se bolela HPMC e nang le viscosity e itseng ea 2.4-3.6CPS. Palo ea 3 e bontša viscosity ea tharollo ea metsi ea 2%, 'me lipalo tse phahameng ka kakaretso li bontša viscosity e phahameng.
2. HPMC E5:
   • Ho tšoana le E3, HPMC E5 e emela sehlopha se fapaneng sa viscosity. Palo ea 5 e bontša viscosity e hakanyetsoang ea 4.0-6.0 CPS ea tharollo ea metsi ea 2%.
3. HPMC E6:
   • HPMC E6 ke sehlopha se seng se nang le profil e fapaneng ea viscosity. Palo ea 6 e bontša viscosity ea 4.8-7.2 CPS ea tharollo ea 2%.
4. HPMC E15:
   • Ho ka etsahala hore ebe HPMC E15 e emela boemo bo phahameng ba viscosity ha e bapisoa le E3, E5, kapa E6. Palo ea 15 e bontša viscosity ea 12.0-18.0CPS ea tharollo ea metsi ea 2%, e leng se bontšang ho tsitsa ho teteaneng.
5. HPMC E50:
   • HPMC E50 e bontša boemo bo phahameng ba viscosity, moo nomoro ea 50 e emelang viscosity ea 40.0-60.0 CPS ea tharollo ea 2%. Boemo bona bo ka 'na ba e-ba le viscosity e phahameng haholo ha e bapisoa le E3, E5, E6, kapa E15.
6. HPMC E4m:
   • “M” ho E4m hangata e bontša viscosity e mahareng ea 3200-4800CPS. HPMC E4m e emela sehlopha se nang le boemo bo mahareng ba viscosity. E ka ba e loketseng lits'ebetsong tse hlokang tekano pakeng tsa ho phalla le botenya.

Ha ho kgethwa sehlopha sa HPMC bakeng sa tshebediso e itseng, dintho tse lokelang ho elwa hloko di kenyeletsa ho qhibidiha ho lakatsehang, ho qhibiliha ha yona, le dibopeho tse ding tsa tshebetso. HPMC e sebediswa hangata diindastering tse kang tsa kaho, meriana, ditlolo le dijo.

Lijong, HPMC hangata e sebelisoa e le tlatsetso lihlahisoa tse seng tsa lebese ho ntlafatsa litšobotsi tse kang ho boloka metsi, ho sebetsa hantle le ho khomarela. Meriana le litlolo, HPMC e sebelisoa bakeng sa litšobotsi tsa eona tsa ho etsa filimi le ho tenya.

Ho bohlokoa ho buisana le moetsi kapa mofani ho fumana tlhahisoleseding e qaqileng ea tekheniki, ho kenyeletsoa le litlhaloso le lits'ebetso tse khothaletsoang bakeng sa sehlopha se seng le se seng sa HPMC. Hangata bahlahisi ba fana ka maqephe a data ea tekheniki le litokomane tsa sehlahisoa ho tataisa basebelisi ho khetha sehlopha se loketseng ka ho fetisisa bakeng sa litlhoko tsa bona tse ikhethileng.
