Ko nga ahuatanga matua ohydroxyethyl methyl cellulose (HEMC)ko:
1. Te whakarewatanga: ka whakarewahia i roto i te wai me etahi whakarewa pararopi, ka taea te whakakore i te HEMC ki te wai makariri, ko te nui o te kaha ka whakatauhia e te viscosity, he rereke te rereke ki te viscosity, te iti o te viscosity, te nui ake o te whakarewatanga.
2. Te tote tote: Ko nga hua HEMC he etera cellulose kore-katote, ehara i te polyelectrolytes, na i te aroaro o nga tote whakarewa, i nga electrolytes waro ranei, he ahua pumau i roto i nga wairewa wai, engari ko te taapiri nui o nga electrolytes ka taea te whakaheke me te ua.
3. Mahi mata: No te mea he mahi mahi mata te wairewa wai, ka taea te whakamahi hei kaihoko tiaki colloid, emulsifier me te dispersant.
4. Thermal gel: When theHEMCka whakamahanahia te wairewa wai hua ki tetahi pāmahana, ka puatakore, ka raera, ka puta he rerenga, engari ka whakamatao tonu, ka hoki ki te ahua otinga taketake, ka puta mai tenei ra me te rerenga. Ko te pāmahana te nuinga ka whakawhirinaki ki o raatau whakahinuhinu, awhina aukati, colloids whakamarumaru, emulsifiers, etc.
5. Te ngoikore o te metabolic me te iti o te kakara me te kakara: Kei te whakamahia nuitia te HEMC ki te kai me te rongoa na te mea kaore i te metabolized he iti te kakara me te kakara.
6. Antifungal: He pai te kaha antifungal a HEMC me te pai o te whakapumautanga i te wa roa o te rokiroki.
7. PH pūmautanga: Ko te pokey o te otinga wai hua HEMC he whakauaua pāngia e te waikawa alkali ranei, a he āhua pūmau te uara pH i roto i te whānuitanga o 3.0-11.0.
Te tono oHydroxyethyl methyl cellulose(HEMC)：
Ka taea te whakamahi Hydroxyethyl methyl cellulose hei kaihoko whakamarumaru colloid, emulsifier me te dispersant na te kaha o te mahi o te mata i roto i te wairewa wai. Ko tetahi tauira o tana whakamahinga e whai ake nei: Ko te paanga o te hydroxyethyl methyl cellulose ki nga ahuatanga o te ciment. Ko te Hydroxyethyl methyl cellulose he paura ma, he hongi, he kore paitini, ka memeha ki te wai matao hei hanga i te wairewa maamaa, kirikiri. Kei a ia nga ahuatanga o te whakapakeke, te here, te whakamarara, te whakaemulsifying, te hanga kiriata, te whakatārewa, te adsorbing, te gelling, te mahi-mata, te pupuri i te makuku me te tiaki i nga colloids. Na te mahi kaha o te mata o te wairewa wai, ka taea te whakamahi hei kaihoko tiaki colloid, he emulsifier me te dispersant. Hydroxyethyl methyl cellulose otinga aqueous he hydrophilicity pai, me te he tino-kakama te māngai pupuri wai.
