Ii-cellulose ethers zinika i-viscosity entle kwi-wet mortar, zinyusa kakhulu amandla okubopha kwe-wet mortar kwi-substrate kwaye ziphucule ukumelana nokuwa kwe-sagging ye-mortar, kwaye zisetyenziswa kakhulu kwi-plastering mortar, kwi-brick bonding mortar nakwiinkqubo zokufakelwa ngaphandle. Isiphumo sokuqina kwe-cellulose ether sinokunyusa amandla okulwa nokusasazeka kunye nokuhambelana kwezinto ezisandula ukuxutywa, ukuthintela ukwahlukana kwezinto, ukwahlulwahlulwa kunye nokukhutshwa kwamanzi, kwaye zingasetyenziswa kwi-fiber concrete, kwi-underground concrete nakwi-self-compact concrete.
Isiphumo sokutyeba kwee-cellulose ethers kwizinto eziqinisayo sivela kwi-viscosity yesisombululo se-cellulose ether. Phantsi kweemeko ezifanayo, xa i-viscosity ye-cellulose ether iphezulu, kokukhona i-viscosity yezinto ezilungisiweyo eziqinisayo ingcono, kodwa ukuba i-viscosity iphezulu kakhulu, iya kuchaphazela ukutyibilika nokusebenza kakuhle kwezinto (umz. iimela zeplasta ezinamathelayo). Ii-mortar ezizilinganisayo kunye ne-concrete eziziqinisayo, ezifuna ukutyibilika okuphezulu, zifuna i-viscosity ephantsi yee-cellulose ethers. Ukongeza, isiphumo sokutyeba kwee-cellulose ethers sonyusa imfuneko yamanzi yezinto eziqinisayo kwaye sonyusa isivuno se-mortar.
Ubuninzi bezisombululo ze-cellulose ether buxhomekeke kwezi zinto zilandelayo: ubunzima be-molecular ye-cellulose ether, uxinaniso, ubushushu, izinga lokucheba kunye nendlela yovavanyo. Phantsi kweemeko ezifanayo, ubunzima be-molecular ye-cellulose ether bukhulu, kokukhona uxinaniso lwesisombululo luphezulu; kokukhona uxinaniso luphezulu, kokukhona uxinaniso lwesisombululo luphezulu, ekusetyenzisweni kwengqwalasela kufuneka kuphetshwe ukulinganisa okugqithisileyo kwaye kuchaphazele iipropati zokusebenza ze-mortar kunye nekhonkrithi; uxinaniso lwesisombululo se-cellulose ether luya kuncipha ngokunyuka kobushushu, kwaye okukhona uxinaniso luphezulu, kokukhona impembelelo yobushushu inkulu; isisombululo se-cellulose ether sidla ngokuba lulwelo lwe-pseudoplastic, olunesimo sokucheba, kokukhona uvavanyo lukhulu Ubungakanani be-shear yovavanyo, kokukhona uxinaniso luncinci, ngoko ke uxinaniso lwe-mortar luya kuncipha phantsi kwesenzo samandla angaphandle, afanelekileyo ekwakhiweni kwe-mortar, ukuze i-mortar ibe nokusebenza kakuhle kunye noxinaniso ngaxeshanye; kuba isisombululo se-cellulose ether silulwelo olungelulo ulwelo lwe-Newtonian, iindlela zovavanyo lwe-viscosity yovavanyo, izixhobo okanye indawo yovavanyo, iziphumo zovavanyo lwe-cellulose ether ezifanayo zinokuhluka kakhulu.
