Ama-cellulose ether anikeza i-viscosity enhle kakhulu ku-wet mortar, akhulisa kakhulu ikhono lokubopha le-wet mortar ku-substrate futhi athuthukise ukumelana nokugoba kwe-mortar, futhi asetshenziswa kabanzi ekuplasteni i-mortar, i-brick bonding mortar kanye nezinhlelo zokushisa zangaphandle. Umphumela wokujiya we-cellulose ether ungandisa nekhono lokulwa nokuhlakazeka kanye nokulingana kwezinto ezisanda kuhlanganiswa, ukuvimbela ukwahlukana kwezinto, ukuhlukaniswa kanye nokukhishelwa kwamanzi, futhi angasetshenziswa kukhonkolo yefayibha, kukhonkolo engaphansi kwamanzi kanye nekhonkolo ezizicindezelayo.
Umphumela wokujiya kwama-cellulose ether ezintweni eziqinisa ubumba uvela ekujiya kwesisombululo se-cellulose ether. Ngaphansi kwezimo ezifanayo, lapho i-viscosity ye-cellulose ether iphakeme, i-viscosity yezinto ezisiqinisa ubumba eziguquliwe iba ngcono, kodwa uma i-viscosity iphezulu kakhulu, izothinta ukujiya nokusebenza kwezinto (isb. imimese ye-plaster enamathelayo). Ama-mortar azilinganisayo kanye nekhonkrithi ezizihlanganisayo, ezidinga ukujiya okuphezulu, zidinga ukujiya okuphansi kwama-cellulose ether. Ngaphezu kwalokho, umphumela wokujiya kwama-cellulose ethers wandisa isidingo samanzi sezinto eziqinisa ubumba futhi wandisa isivuno sekhonkrithi.
Ukuqina kwezixazululo ze-cellulose ether kuncike kulezi zici ezilandelayo: isisindo sama-molecule se-cellulose ether, ukuhlushwa, izinga lokushisa, izinga lokucheba kanye nendlela yokuhlola. Ngaphansi kwezimo ezifanayo, lapho isisindo sama-molecule se-cellulose ether sikhulu, kulapho ukuhlushwa kuphakama khona; lapho ukuhlushwa kuphakama, kulapho ukuhlushwa kuphakama khona, kufanele kuqashelwe ukusetshenziswa ukuze kugwenywe ukudonswa ngokweqile futhi kuthinte izakhiwo zokusebenza ze-mortar kanye nekhonkrithi; i-cellulose ether solution viscosity izoncipha ngokukhuphuka kwezinga lokushisa, futhi lapho ukuhlushwa kuphakama, kulapho izinga lokushisa liba likhulu khona; isixazululo se-cellulose ether ngokuvamile siwuketshezi lwe-pseudoplastic, olunesimo sokuncipha kwe-shear, kulapho ukuhlolwa kuba kukhulu khona. Isilinganiso sokucheba sikhulu se-test, kulapho ukuhlushwa kuncipha khona, ngakho-ke ukuhlangana kwe-mortar kuzoncishiswa ngaphansi kwesenzo samandla angaphandle, okusiza ekwakheni i-mortar, ukuze i-mortar ibe nokusebenza kahle kanye nokuhlangana ngesikhathi esifanayo; ngoba isixazululo se-cellulose ether siwuketshezi olungeyona i-Newtonian, izindlela zokuhlola i-viscosity yokuhlola, izinsimbi noma indawo yokuhlola, imiphumela yokuhlola isixazululo se-cellulose ether efanayo ingahluka kakhulu.
