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

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

1. HPMC E3:
   • Kereiti ena e kanna ea bua ka HPMC e nang le viscosity e khethehileng ea 2.4-3.6CPS. Nomoro ea 3 e bonts'a viscosity ea 2% ea tharollo ea metsi, 'me lipalo tse phahameng ka kakaretso li bontša viscosity e phahameng.
2. HPMC E5:
   • E ts'oanang le E3, HPMC E5 e emetse sehlopha se fapaneng sa viscosity. Nomoro ea 5 e bontša hoo e ka bang viscosity 4.0-6.0 CPS ea 2% ea tharollo ea metsi.
3. HPMC E6:
   • HPMC E6 ke mophato o mong o nang le boemo bo fapaneng ba viscosity. Nomoro ea 6 e bolela viscosity 4.8-7.2 CPS ea tharollo ea 2%.
4. HPMC E15:
   • HPMC E15 mohlomong e emetse sehlopha sa viscosity e phahameng ha e bapisoa le E3, E5, kapa E6. Nomoro ea 15 e bonts'a viscosity 12.0-18.0CPS ea 2% ea tharollo ea metsi, e fana ka maikutlo a ho tsitsisa ho hoholo.
5. HPMC E50:
   • HPMC E50 e bontša boemo bo phahameng ba viscosity, ka palo ea 50 e emelang viscosity 40.0-60.0 CPS ea tharollo ea 2%. Kereiti ena e kanna ea ba le viscosity e phahameng haholo ha e bapisoa le E3, E5, E6, kapa E15.
6. HPMC E4m:
   • "M" ho E4m hangata e bolela viscosity e mahareng 3200-4800CPS. HPMC E4m e emetse kereiti e nang le boemo bo itekanetseng ba viscosity. E ka ba e loketseng bakeng sa lits'ebetso tse hlokang ho leka-lekana pakeng tsa metsi le botenya.

Ha u khetha kereiti ea HPMC bakeng sa ts'ebeliso e itseng, mehopolo e kenyelletsa viscosity e lakatsehang, solubility, le litšobotsi tse ling tsa ts'ebetso. HPMC e sebelisoa hangata liindastering tse kang kaho, meriana, litlolo, le lijo.

Lijong, HPMC hangata e sebelisoa e le tlatsetso ea lihlahisoa tse sa thehiloeng lebeseng ho ntlafatsa thepa e kang ho boloka metsi, ho sebetsa le ho khomarela. Litlhare le litlolo, HPMC e sebelisoa bakeng sa thepa ea eona ea ho etsa lifilimi le ho tiisa.

Ho bohlokoa ho buisana le moetsi kapa mofani oa thepa ho fumana lintlha tse qaqileng tsa tekheniki, ho kenyeletsoa litlhaloso le likopo tse khothaletsoang bakeng sa kereiti ka 'ngoe ea HPMC. Baetsi ka tloaelo ba fana ka maqephe a data a tekheniki le litokomane tsa lihlahisoa ho tataisa basebelisi ho khetha kereiti e loketseng litlhoko tsa bona tse ikhethileng.
