Litšobotsi tse ka sehloohong tsahydroxyethyl methyl cellulose (HEMC)ke:
1. Ho qhibiliha: ho qhibiliha ka metsing le li-solvents tse ling, HEMC e ka qhibiliha metsing a batang, mahloriso a eona a mangata a khethoa feela ke viscosity, solubility e fapana le viscosity, e tlaase ea viscosity, e kholoanyane ea solubility.
2. Ho hanyetsa letsoai: Lihlahisoa tsa HEMC ha li na ionic cellulose ethers 'me ha li polyelectrolyte, kahoo ka pel'a letsoai la tšepe kapa li-electrolyte tsa organic, li batla li tsitsitse ka tharollo ea metsi, empa ho eketsoa ka mokhoa o feteletseng oa electrolyte ho ka baka gelation le pula.
3. Mosebetsi oa holim'a metsi: Hobane tharollo e nang le metsi e na le ts'ebetso ea holim'a metsi, e ka sebelisoa e le moemeli oa tšireletso ea colloid, emulsifier le dispersant.
4. Thermal gel: HaHEMCsehlahisoa aqueous tharollo e halefile ho mocheso o itseng, e fetoha opaque, li-gel, 'me e theha pula, empa ha e tsoela pele ho pholile, e khutlela sebakeng sa pele sa tharollo,' me gel ena le pula e etsahala. Thempereichara haholo-holo e itšetlehile ka mafura a bona, lithuso tsa ho emisa, li-colloids tse sireletsang, li-emulsifiers, joalo-joalo.
5. Metabolic inertness le monko o fokolang le monko o monate: HEMC e sebelisoa haholo lijong le meriana hobane ha e na metabolized mme e na le monko o fokolang le monko o monate.
6. Antifungal: HEMC e na le bokhoni bo botle ba antifungal le botsitso bo botle ba viscosity nakong ea polokelo ea nako e telele.
7. Ho tsitsa ha PH: The viscosity ea sehlahisoa sa lihlahisoa tsa HEMC tharollo ea metsi ha e amehe ka thata ke acid kapa alkali, 'me boleng ba pH bo batla bo tsitsitse ho 3.0-11.0.
Kopo eaHydroxyethyl methyl cellulose (HEMC):
Hydroxyethyl methyl cellulose e ka sebelisoa e le moemeli oa tšireletso ea colloid, emulsifier le dispersant ka lebaka la ts'ebetso ea eona e sebetsang ka holim'a tharollo ea metsi. Mohlala oa tšebeliso ea eona ke o latelang: Phello ea hydroxyethyl methyl cellulose ho thepa ea samente. Hydroxyethyl methyl cellulose ke phofo e tšoeu e sa nkheng, e sa latsoeheng, e se nang chefo e qhibilihang ka metsing a batang ho etsa tharollo e hlakileng, e hlakileng. E na le thepa ea ho tiisa, ho tlama, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, surface-active, ho boloka mongobo le ho sireletsa li-colloids. Ka lebaka la ts'ebetso e sebetsang ea holim'a metsi a metsi, e ka sebelisoa e le moemeli oa tšireletso ea colloid, emulsifier le dispersant. Hydroxyethyl methyl cellulose aqueous solution e na le hydrophilicity e ntle 'me ke sesebelisoa se bolokang metsi se sebetsang hantle haholo.
