Izici eziyinhloko zei-hydroxyethyl methyl cellulose (HEMC)yilezi:
1. I-Solubility: i-solubility emanzini kanye namanye ama-solvents ephilayo, i-HEMC ingancibilika emanzini abandayo, ukugxila kwayo okuphezulu kunqunywa kuphela yi-viscosity, ukuncibilika kuyahlukahluka nge-viscosity, i-viscosity ephansi, i-solubility enkulu.
2. Ukumelana nosawoti: Imikhiqizo ye-HEMC i-non-ionic cellulose ethers futhi ayiwona ama-polyelectrolytes, ngakho-ke phambi kosawoti wensimbi noma ama-electrolyte ephilayo, azinzile kuzixazululo ezinamanzi, kodwa ukwengezwa ngokweqile kwama-electrolyte kungabangela i-gelation kanye nemvula.
3. Umsebenzi ongaphezulu: Ngenxa yokuthi isixazululo esinamanzi sinomsebenzi ongaphezulu, singasetshenziswa njenge-colloid evikelayo, i-emulsifier ne-dispersant.
4. Ijeli eshisayo: Lapho i-I-HEMCIsixazululo se-aqueous somkhiqizo sishisiswe ekushiseni okuthile, siba yi-opaque, ama-gel, futhi sakha imvula, kodwa lapho sipholile ngokuqhubekayo, sibuyela esimweni sokuqala sesisombululo, futhi le gel kanye nemvula kwenzeka. Izinga lokushisa lincike ikakhulukazi kumafutha abo, izinsiza zokumisa, ama-colloid avikelayo, ama-emulsifiers, njll.
5. Ukungabi namandla kwe-Metabolic kanye nephunga eliphansi kanye nephunga elimnandi: I-HEMC isetshenziswa kakhulu ekudleni nasemthini ngenxa yokuthi ayigayelwanga futhi inephunga eliphansi kanye nephunga elimnandi.
6. I-Antifungal: I-HEMC inekhono elihle le-antifungal kanye nokuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.
7. Ukuzinza kwe-PH: I-viscosity yesisombululo se-aqueous somkhiqizo we-HEMC ayithintwa neze i-asidi noma i-alkali, futhi inani le-pH lizinzile ngokuqhathaniswa kububanzi obungu-3.0-11.0.
Isicelo seIHydroxyethyl methyl cellulose (HEMC):
I-Hydroxyethyl methyl cellulose ingasetshenziswa njenge-ejenti yokuvikela i-colloid, i-emulsifier kanye ne-dispersant ngenxa yokusebenza kwayo okungaphezulu okusebenzayo kusixazululo esinamanzi. Isibonelo sokusetshenziswa kwawo simi kanje: Umphumela we-hydroxyethyl methyl cellulose ezakhiweni zikasimende. IHydroxyethyl methyl cellulose iyimpushana emhlophe engenaphunga, enganambitheki, engenabuthi encibilika emanzini abandayo ukuze yakhe isixazululo esicacile, esibonakalayo. Inezici zokuqina, ukubopha, ukuhlakaza, i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, i-gelling, i-surface-active, igcina umswakama kanye nokuvikela ama-colloid. Ngenxa yomsebenzi osebenzayo wesisombululo se-aqueous, ingasetshenziswa njenge-ejenti yokuzivikela ye-colloid, i-emulsifier kanye ne-dispersant. Isixazululo samanzi se-Hydroxyethyl methyl cellulose sine-hydrophilicity enhle futhi iyi-ejenti yokugcina amanzi esebenza kahle kakhulu.
