I-Methyl hydroxyethyl celluloseilungiswa ngokwethula izinto ezifakwa esikhundleni se-ethylene oxide (MS0.3~0.4) ku-methyl cellulose, futhi izinga lokushisa layo lejeli liphakeme kunalelo le-methyl cellulose ne-methyl hydroxypropyl cellulose. , ukusebenza kwayo okuphelele kungcono kune-methyl cellulose ne-methyl hydroxypropyl cellulose.
I-Methyl hydroxyethyl cellulose isetshenziswa kakhulu njenge-thickener, stabilizer kanye ne-colloid evikelayo odakeni lwezakhiwo kanye nezingubo ezisekelwe emanzini.

Izakhiwo zomzimba namakhemikhali
1. I-Solubility: i-solubility emanzini nezinye izincibilikisi eziphilayo, ukuhlushwa okuphezulu kakhulu kuncike kuphela ku-viscosity, ukuncibilika kuyashintsha nge-viscosity, i-viscosity ephansi, i-solubility enkulu.
2. Ukumelana nosawoti: Umkhiqizo i-non-ionic cellulose ether, ozinzile kusisombululo samanzi, kodwa ukwengeza ngokweqile kwe-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: Uma isixazululo esinamanzi somkhiqizo sishiselwa ezingeni lokushisa elithile, siba yi-opaque, amajeli, futhi sakhe imvula, kodwa lapho sipholiswa ngokuqhubekayo, sibuyela esimweni sokuqala sesixazululo.
5. I-Metabolism: I-Metabolism ine-inert futhi inephunga eliphansi kanye nephunga elimnandi. Ngenxa yokuthi awagaywanga futhi anephunga eliphansi nephunga elimnandi, asetshenziswa kakhulu ekudleni nasemithini.
6. Ukumelana nesikhutha: Inekhono elihle lokunqanda isikhutha kanye nokuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.
7. Ukuzinza kwe-PH: I-viscosity yesisombululo esinamanzi somkhiqizo ayithintwa neze i-asidi noma i-alkali, futhi inani le-PH lizinzile ngokuqhathaniswa kububanzi obungu-3.0-11.0.
8. Okuqukethwe komlotha ophansi: Njengoba umkhiqizo ungewona i-ionic, uhlanjululwa ngokuphumelelayo ngokugeza ngamanzi ashisayo ngesikhathi senqubo yokulungiselela, ngakho okuqukethwe kwawo komlotha kuphansi kakhulu.
9. Ukugcinwa komumo: Njengoba isixazululo esinamanzi esigxile kakhulu somkhiqizo sinezici ezikhethekile ze-viscoelastic uma kuqhathaniswa nezixazululo ezinamanzi zamanye ama-polymers, ukungezwa kwaso kunamandla okuthuthukisa ukuma kwemikhiqizo ye-ceramic ekhishwe.
10. Ukugcinwa kwamanzi: I-hydrophilicity yomkhiqizo kanye ne-viscosity ephezulu yesisombululo sawo samanzi kuwenza ube i-ejenti ephumelelayo yokugcina amanzi.
