1. Sebopeho sa Molek'hule:
Hpmc e5:
HPMC E5 e bua ka sehlopha sa HPMC ka tekanyo e tlase ea sebaka sa Hydroxypropyl le lihlopha tsa Methotox li bapisoa le E15.
Tekanyo e tlase ea sebaka e bonts'a mefuta e 'ngoe ea hydroxy ea hydroxypropyl le lihlopha tsa methola
Hpmc e15:
Ka lehlakoreng le leng, HPMC E15 e na le sebaka se phahameng sa sebaka sa hydroxypropyl le lihlopha tsa mekhoa e bapisoang le E5.
Sena se bolela ho feta palo e kholo ea li-hydropypropyl le lihlopha tsa Methoxy ka Sebele sa Cellulose Chain.
2. Viscosity:
Hpmc e5:
HPMC e5 e na le pono e tlase ha e bapisoa le E15.
Hangata limaraka tse tlase tsa Viscossity tse kang E5 li sebelisoa ha phello e tlase ea ho holisa e lakatseha ho etsa liforomo.
Hpmc e15:
HPMC e15 e na le pono e phahameng e bapisoang le E5.
Metsoako e phahameng ea litšoantšo e kang e15 e khethoa ha mefuta e metle ea metsi e hlokahala kapa thepa ea ho boloka metsi e le betere ea metsi.
3. Allubity ea metsi:
Hpmc e5:
Bobeli ba hpmc e5 le e15 ke polyers ea metsi e qhibilihang metsi.
Leha ho le joalo, qubuli e ka fapana hanyane ho latela likarolo tse ling tsa foromo le maemo a tikoloho.
Hpmc e15:
Joalo ka E5, HPMC E15 e qhibiliha habonolo ka metsing.
E bapala ka ho hlaka, ho lemoha tharollo ea ho qhalana.
4. Likopo:
Hpmc e5:
HPMC E5 e sebelisoa hangata lits'ebetsong moo pono e tlase le e lekaneng e lakatsehang.
Mehlala ea Likopo e kenyelletsa:
Litlhaloso tsa meriana (joalo ka li-branter, li-curienter, kapa li-agents tse laoloang).
Lihlahisoa tsa tlhokomelo ea motho (e le li-thickeners ka li-inf, litlolo le shampoos).
Indasteri ea lijo (joalo ka moemeli ea kopaneng kapa thickener).
Indasteri ea kaho (e le ea eketsang lihlahisoa tse thehiloeng ho saense bakeng sa ho ntlafatsa mesebetsi ea metsi le ho boloka metsi).
Hpmc e15:
HPMC E15 e khethoa likopo tse hlokang pono e phahameng le thepa e matla ea matla.
Likopo tsa HPMC e15 li kenyeletsa:
Likhatiso tsa pharmaceutical (e le li-agents tsa li-gilling, litheolelo tsa li-viscosity, kapa li-agents tse tšehelitsoeng).
Lisebelisoa tsa moaho (joalo ka thipa kapa mokhoa o mongata kapa o momahaneng oa likhoele, oa polasetiki kapa koro).
Indasteri ea lijo (joalo ka moemeli ea toneng ho souces, puddings, kapa lihlahisoa tsa lebese).
Indasteri ea litlolo (ka lihlahisoa tse hlokang pono e phahameng, joalo ka li-gels tsa moriri kapa li-mousses tse halikiloeng).
5. Ts'ebetso ea Tlhahiso:
Hpmc e5 le e15:
Ts'ebetso ea Tlhahiso ea HPMC E15 le E15 e kenyelletsa phallo ea cellouse ea nang le cellouse ea nang le Cellene Oxide le Methyl chloride.
Degree of karolelano e laoloa nakong ea syntthesis ho fihlela thepa e lakatsehang.
Mahlaseli a fapa-fapaneng a kang nako, mocheso, 'me karo-rang ea limpho e ntlafalitsoe ho hlahisa HPMC ka litšobotsi tse ikhethang.
Liphapang tsa mantlha lipakeng tsa HPMC E5 le e15 li bua ka sebopeho sa tsona sa lisele tsa boolele, litšoantšiso le likopo. Ha limaraka tse peli li na le mekotla e qhibilihileng ea metsi, HPMC e5 e na le sebaka se tlase le pono e bapisoang le hpmc e15. Ka lebaka leo, E5 e loketse likopo tse hlokang lipehelo tse tlase le mekhoa e metle ea ho etsa joalo, athe e khetha ho hloka liqeto tse phahameng le litlamorao tse matla. Ho utloisisa liphapang tsena ho bohlokoa bakeng sa ho khetha sehlopha se loketseng hpmc bakeng sa likhatiso le likopo tse ikhethang.
