Methyl hydroxyethyl cellulosehe mea whakarite ma te whakauru i nga whakakapi o te ethylene oxide (MS0.3~0.4) ki roto i te methyl cellulose, a, he teitei ake te mahana o te reera i tera o te methyl cellulose me te methyl hydroxypropyl cellulose. , he pai ake tana mahi matawhānui i te methyl cellulose me te methyl hydroxypropyl cellulose.
Ko te Methyl hydroxyethyl cellulose te nuinga o te whakamahi hei whakapakeke, whakapumau me te colloid whakamarumaru i roto i te kumete hoahoanga me nga paninga wai.

Ngā āhuatanga ā-tinana, matū hoki
1. Wairewa: ka whakarewahia i roto i te wai me etahi whakarewa waro, ko te kukū teitei ka whakawhirinaki anake ki te pokey, ka huri te memehatanga ki te pokey, te iti o te pokey, te nui ake o te whakarewatanga.
2. Tote ātete: Ko te hua ko te kore-katote cellulose ether, i te āhua pūmau i roto i te wairewa wai, engari nui tāpiritanga o te electrolyte taea meinga gelation me te rerenga.
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. Ngaariki waiariki: Ka werahia te wairewa wai o te hua ki tetahi pāmahana, ka noho puatakore, ka raera, ka puta he rerenga, engari ka whakamatao tonu, ka hoki ki te ahua otinga taketake.
5. Te Metabolism: He mokowhiti te kawa, he iti te kakara me te kakara. Na te mea karekau i te whakakorikori, he iti te kakara me te kakara, ka whakamahia nuitia ki te kai me te rongoa.
6. Te atete o te koriri: He pai te kaha anti-koriri me te pai o te whakapumautanga i te wa roa o te rokiroki.
7. PH pūmautanga: Ko te pokey o te wairewa wai o te hua e whakauaua pāngia e te waikawa alkali ranei, a he āhua pūmau te uara PH i roto i te whānuitanga o 3.0-11.0.
8. He iti te pungarehu o te pungarehu: I te mea ko te hua kaore i te katote, he pai te para ma te horoi ki te wai wera i te wa o te whakaritenga, na reira he iti rawa te kiko o te pungarehu.
9. Te pupuri i te ahua: Na te mea ko te wairewa wai tino kaha o te hua he mea motuhake te viscoelastic i whakaritea ki nga wairewa wai o etahi atu polymers, ko tana taapiri he kaha ki te whakapai ake i te ahua o nga hua karameka.
10. Te pupuri wai: Ko te hydrophilicity o te hua me te nui o te pokey o tona wairewa wai ka waiho hei kaihoko pupuri wai pai.
