I-cellulose ether ivamise ukuba yingxenye esemqoka odakeni oluxutshwe okomile.Ngoba iyi-ejenti ebalulekile yokugcina amanzi enezindawo ezinhle kakhulu zokugcina amanzi.Lesi sakhiwo sokugcina amanzi singavimbela amanzi odaka olumanzi ukuthi angahwamuki ngaphambi kwesikhathi noma amuncwe yi-substrate, andise isikhathi sokusebenza sodaka olumanzi, aqinisekise ukuthi usimende ugcwele amanzi ngokugcwele, futhi ngaleyo ndlela ekugcineni uqinisekisa izakhiwo zemishini zodaka, okuyinto kunenzuzo ikakhulukazi ekwakhiweni kodaka oluncane oluncane (njengolukhonkolo) kanye nodaka kuma-substrates amunca kakhulu (njengamabhulokhi kakhonkolo afakwa umoya), izinga lokushisa eliphezulu nezimo ezomile.
Impahla yokugcina amanzi ye-cellulose ihlobene kakhulu ne-viscosity yayo.Ukuphakama kwe-viscosity ye-cellulose ether, kuba ngcono ukusebenza kokugcinwa kwamanzi.I-Viscosity iyipharamitha ebalulekile yokusebenza kwe-MC.Njengamanje, abakhiqizi be-MC abahlukene basebenzisa izindlela ezahlukene nezinsimbi zokuhlola i-viscosity ye-MC, futhi izindlela eziyinhloko yi-Haake Rotovisko, i-Hoppler, i-Ubbelohde ne-Brookfield.Ngomkhiqizo ofanayo, imiphumela ye-viscosity elinganiswa ngezindlela ezihlukene iyahluka kakhulu, futhi eminye ihluke kakhulu.Ngakho-ke, uma uqhathanisa ama-viscosities, kubalulekile ukwenza kanjalo phakathi kwezindlela ezifanayo zokuhlola, kufaka phakathi izinga lokushisa, i-rotor, njll.
Ngokuvamile, ukuphakama kwe-viscosity, kuba ngcono umphumela wokugcina amanzi.Kodwa-ke, ukuphakama kwe-viscosity, ukuphakama kwesisindo samangqamuzana e-MC kanye nokwehla okuhambisanayo kokuncibilika kwayo, okunomthelela omubi emandleni nokusebenza kokwakhiwa kodaka.Ukuphakama kwe-viscosity, kusobala kakhulu umphumela wokuqina odongeni.Ukuphakama kwe-viscosity, udaka olumanzi luyoba lukhulu, kokubili ekwakheni, njengoba kuboniswa i-scraper enamathelayo kanye nokunamathela okuphezulu ku-substrate.Kodwa-ke, akusizi kakhulu ukukhulisa amandla esakhiwo sodaka olumanzi ngokwalo.Uma kokubili ukwakhiwa, kukhombisa ukusebenza kwe-anti-sagging akubonakali.Ngokuphambene, i-viscosity ethile ephansi ukuya emaphakathi kodwa eshintshiwe ye-methyl cellulose ethers inokusebenza okuhle kakhulu ekuthuthukiseni amandla esakhiwo sodaka olumanzi.
