ʻO nā hiʻohiʻona nui ohydroxyethyl methyl cellulose (HEMC)he:
1. Solubility: hiki ke hoʻoheheʻe ʻia i ka wai a me kekahi mau mea hoʻoheheʻe organik, hiki ke hoʻoheheʻe ʻia ka HEMC i ka wai anuanu, ʻo ka nui o ka nui o ka hoʻoholo ʻana e ka viscosity, ʻokoʻa ka solubility me ka viscosity, ʻoi aku ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility.
2. Paʻakai kū'ē: HEMC huahana he non-ionic cellulose ethers aʻaʻole polyelectrolytes, no laila, i ke alo o ka metala paʻakai a organic electrolytes, ua 'ano paʻa i loko o ka wai, akā, excessive hoʻohui o electrolytes hiki ke kumu gelation a me ka ua.
3. Ka hana o ka ʻili: No ka mea, he hana ʻoihana o ka ʻili wai, hiki ke hoʻohana ʻia e like me ka colloid protection agent, emulsifier a me dispersant.
4. Thermal gel: KeHEMCHoʻomaʻamaʻa ʻia ka hopena aqueous huahana i kahi mahana, lilo ia i opaque, gels, a hana i kahi precipitate, akā i ka wā e hoʻomau mau ʻia, hoʻi ia i ke kūlana hoʻonā kumu, a hiki mai kēia gel a me ka ua. ʻO ka mahana e hilinaʻi nui ʻia i kā lākou lubricants, nā mea kōkua hoʻomaha, nā colloids pale, emulsifiers, etc.
5. Metabolic inertness a me ka haʻahaʻa ʻala a me ka ʻala: HEMC i hoʻohana nui ʻia i ka meaʻai a me ka lāʻau lapaʻau no ka mea ʻaʻole ia i hoʻoheheʻe ʻia a he haʻahaʻa haʻahaʻa a me ke ʻala.
6. Antifungal: HEMC maikaʻi ka mana antifungal a me ka paʻa viscosity maikaʻi i ka wā mālama lōʻihi.
7. PH paʻa: Ka viscosity o ka HEMC huahana aqueous solution ua paʻakikī ʻole i ka waika a i ʻole ka alkali, a paʻa ka pH waiwai ma ka laulā o 3.0-11.0.
Noi oHydroxyethyl methyl cellulose (HEMC)：
Hiki ke hoʻohana ʻia ka hydroxyethyl methyl cellulose e like me ka colloid protection agent, emulsifier a me ka dispersant ma muli o kāna hana ʻeleʻele i ka wai. ʻO kahi laʻana o kāna noi penei: ʻO ka hopena o ka hydroxyethyl methyl cellulose i nā waiwai o ka sima. ʻO ka Hydroxyethyl methyl cellulose he pauka keʻokeʻo ʻole, ʻono ʻole, ʻawaʻawa ʻole e hoʻoheheʻe ʻia i loko o ka wai anuanu e hana ai i kahi hopena akaka. Loaʻa iā ia nā waiwai o ka mānoanoa, hoʻopaʻa, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface-active, hoʻopaʻa i ka wai a me ka pale ʻana i nā colloids. Ma muli o ka hana o ka ʻili o ka wai, hiki ke hoʻohana ʻia e like me kahi mea pale colloid, emulsifier a me kahi dispersant. ʻO Hydroxyethyl methyl cellulose aqueous solution he hydrophilicity maikaʻi a he mea hoʻopaʻa wai kiʻekiʻe.
