I-cellulose ether ivame ukuba yingxenye ebalulekile kuma-mortar axutshwe okomile. Ngoba iyi-ejenti ebalulekile yokugcina amanzi enezakhiwo ezinhle kakhulu zokugcina amanzi. Le mpahla yokugcina amanzi ingavimbela amanzi ku-mortar emanzi ukuthi angahwamuki ngaphambi kwesikhathi noma amuncwe yi-substrate, yandise isikhathi esisebenzayo se-mortar emanzi, iqinisekise ukuthi usimende umanzi ngokuphelele, futhi ngaleyo ndlela ekugcineni kuqinisekiswe izakhiwo zemishini ze-mortar, ezizuzisa kakhulu ekwakhiweni kwama-mortar amancane (njenge-plastering mortars) kanye nama-mortar ezindaweni ezimunca kakhulu (njenge-concrete blocks enomoya), izinga lokushisa eliphezulu kanye nezimo ezomile.
Impahla yokugcina amanzi ye-cellulose ihlobene kakhulu ne-viscosity yayo. Uma i-viscosity ye-cellulose ether iphakeme, kulapho ukusebenza kokugcina amanzi kuba ngcono khona. I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-MC. Njengamanje, abakhiqizi be-MC abahlukene basebenzisa izindlela ezahlukene namathuluzi ukuhlola i-viscosity ye-MC, futhi izindlela eziyinhloko yiHaake Rotovisko, iHoppler, i-Ubbelohde kanye neBrookfield. Ngomkhiqizo ofanayo, imiphumela ye-viscosity elinganiswa ngezindlela ezahlukene iyahlukahluka kakhulu, futhi eminye ihluke kakhulu. Ngakho-ke, uma uqhathanisa i-viscosities, kubalulekile ukwenza kanjalo phakathi kwezindlela zokuhlola ezifanayo, kufaka phakathi izinga lokushisa, i-rotor, njll.
Ngokuvamile, uma i-viscosity iphakeme, umphumela wokugcina amanzi uba ngcono. Kodwa-ke, uma i-viscosity iphakeme, isisindo sama-molecule se-MC siphakeme kanye nokwehla okuhambisanayo kokuncibilika kwayo, okunomthelela omubi emandleni nasekusebenzeni kokwakhiwa kwe-mortar. Uma i-viscosity iphakeme, umphumela wokujiya ubonakala kakhulu ku-mortar. Uma i-viscosity iphakeme, kulapho i-mortar emanzi inamathela khona, kokubili ekwakheni, njengoba kuboniswe yi-sticky scraper kanye nokunamathela okuphezulu ku-substrate. Kodwa-ke, akusizi kakhulu ukwandisa amandla esakhiwo se-mortar emanzi uqobo. Lapho kokubili kwakhiwa, kukhombisa ukuthi ukusebenza kokulwa nokugoba akubonakali. Ngokuphambene nalokho, amanye ama-viscosity aphansi kuya kwaphakathi kodwa aguquliwe e-methyl cellulose ethers asebenza kahle kakhulu ekuthuthukiseni amandla esakhiwo se-mortar emanzi.
