Udaka oluzilinganisa lungathembela esisindweni salo ukuze lwakhe isisekelo esiyisicaba, esibushelelezi nesiqinile ku-substrate yokubeka noma yokuhlanganisa ezinye izinto. Ngesikhathi esifanayo, ingakwazi ukwenza ukwakhiwa okukhulu nokusebenza kahle. Ngakho-ke, i-fluidity ephezulu iyisici esibaluleke kakhulu se-self-leveling mortar Ngaphezu kwalokho, kufanele ibe nokugcinwa kwamanzi athile namandla okubopha, kungabikho mkhuba wokuhlukaniswa kwamanzi, futhi ibe nezici zokushisa ukushisa nokukhuphuka okuphansi kwezinga lokushisa.
Ngokuvamile, udaka lokuzilinganisa ludinga uketshezi oluhle. I-Cellulose ether iyisengezo esiyinhloko sikadaka oseluxubile. Nakuba inani elingeziwe liphansi kakhulu, lingathuthukisa kakhulu ukusebenza kodaka. Ingathuthukisa ukungaguquguquki, ukusebenza kahle kanye nokuhlangana kodaka. ukusebenza nokugcinwa kwamanzi. Idlala indima ebaluleke kakhulu emkhakheni wodaka osulungile.
I-Cellulose ether inethonya elibalulekile ekugcineni amanzi, ukungaguquguquki kanye nokusebenza kokwakhiwa kodaka oluzilinganisa. Ikakhulukazi njengodaka oluzilinganisa, uketshezi lungenye yezinkomba eziyinhloko zokuhlola ukusebenza kokuzilinganisa. Ngaphansi kwesisekelo sokuqinisekisa ukubunjwa okuvamile kodaka, uketshezi lodaka lungalungiswa ngokushintsha inani le-cellulose ether. Kodwa-ke, uma umthamo uphezulu kakhulu, ukumanzi kwesakhi kuzoncishiswa, ngakho-ke umthamo we-cellulose ether kufanele ulawulwe ngaphakathi kwebanga elinengqondo.
Ukugcinwa kwamanzi kodaka kuyinkomba ebalulekile yokulinganisa ukuzinza kwezingxenye zangaphakathi zodaka lukasimende olusanda kuxutshwa. Ukuze ufeze ngokugcwele ukusabela kwe-hydration yezinto zejeli, inani elifanele le-cellulose ether lingagcina umswakama odongeni isikhathi eside. Ngokuvamile, izinga lokugcinwa kwamanzi lwe-slurry likhuphuka ngokunyuka kokuqukethwe kwe-cellulose ether. Umphumela wokugcina amanzi we-cellulose ether ungavimbela i-substrate ekumunceni amanzi amaningi ngokushesha kakhulu, futhi ivimbele ukuhwamuka kwamanzi, ukuze kuqinisekiswe ukuthi indawo yodaka ihlinzeka ngamanzi anele ukuze usimende usinde. Ngaphezu kwalokho, i-viscosity ye-cellulose ether nayo inethonya elikhulu ekugcinweni kwamanzi odaka. Ukuphakama kwe-viscosity, kungcono ukugcina amanzi. Ngokuvamile, i-cellulose ether ene-viscosity engu-400mpa.s isetshenziswa kakhulu kudaka oluzilinganisa, olungathuthukisa ukusebenza kokulingana kodaka futhi kwandise ukubumbana kodaka.
