Udaka oluzilinganisayo lunokuxhomekeka kubunzima balo ukwenza isiseko esisicaba, esigudileyo kunye nesiqinileyo kwi-substrate yokubeka okanye ukudibanisa ezinye izinto. Kwangaxeshanye, inokuqhuba ulwakhiwo olukhulu nolusebenzayo. Ngoko ke, i-fluidity ephezulu yinto ebaluleke kakhulu ye-self-leveling mortar Ukongeza, kufuneka ibe nokugcinwa kwamanzi athile kunye namandla okudibanisa, akukho nto yokwahlula kwamanzi, kwaye ibe neempawu zokufudumeza ukushisa kunye nokunyuka kweqondo lokushisa eliphantsi.
Ngokubanzi, udaka oluzilinganisa ngokwalo lufuna ubumanzi obulungileyo. I-ether ye-cellulose iyona nto yokongeza i-mortar esele ixutywe. Nangona imali eyongeziweyo iphantsi kakhulu, inokuphucula kakhulu ukusebenza kodaka. Inokuphucula ukuhambelana, ukusebenza kunye nokudityaniswa kodaka. ukusebenza kunye nokugcinwa kwamanzi. Idlala indima ebaluleke kakhulu kwintsimi yodaka olulungeleyo.
I-ether ye-cellulose inempembelelo ebalulekileyo ekugcinweni kwamanzi, ukuhambelana kunye nokusebenza kokwakhiwa kwe-self-leveling mortar. Ngokukodwa njengodaka lokuzilinganisa, ukumanzi sesinye sezibonakaliso eziphambili zokuvavanya ukusebenza kokuzilinganisa. Ngaphantsi kwesiseko sokuqinisekisa ukubunjwa okuqhelekileyo kodaka, ukunyanzeliswa kodaka kunokulungiswa ngokutshintsha inani le-cellulose ether. Nangona kunjalo, ukuba idosi iphezulu kakhulu, i-fluidity ye-mortar iya kuncitshiswa, ngoko ke idosi ye-cellulose ether kufuneka ilawulwe ngaphakathi koluhlu olufanelekileyo.
Ukugcinwa kwamanzi kwi-mortar yisalathisi esibalulekileyo sokulinganisa ukuzinza kwamacandelo angaphakathi kwi-sand mortar ye-cement. Ukuze ufezekise ngokupheleleyo ukuphendulwa kwe-hydration yezinto ze-gel, isixa esifanelekileyo se-cellulose ether sinokugcina umswakama kwi-mortar ixesha elide. Ngokuqhelekileyo, izinga lokugcinwa kwamanzi kwi-slurry liyenyuka ngokunyuka kwe-cellulose ether content. Ukugcinwa kwamanzi kwi-ether ye-cellulose kunokuthintela i-substrate ekufunxeni amanzi amaninzi ngokukhawuleza, kwaye ithintele ukuphuphuma kwamanzi, ukuze kuqinisekiswe ukuba indawo ye-slurry ibonelela ngamanzi aneleyo kwi-samente hydration. Ukongezelela, i-viscosity ye-cellulose ether nayo inempembelelo enkulu ekugcinweni kwamanzi omdaka. Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi. Ngokuqhelekileyo, i-cellulose ether ene-viscosity ye-400mpa.s isetyenziswa kakhulu kwi-self-leveling mortar, enokuthi iphucule ukusebenza komgangatho wodaka kunye nokwandisa ukuqina kodaka.
