Iimbumba ezizimeleyo zixhomekeke kubunzima bazo ukuba zenze isiseko esisicaba, esilula kunye nesiqinileyo kwi-substrate, evumela ukuba ezinye izinto zibekwe okanye ziboshwe, ngelixa zifezekisa iindawo ezinkulu, ezifanelekileyo zokwakha. Ke ngoko, ulwelo oluphezulu luphawu olubaluleke kakhulu lodaka oluzilinganisa ngodaka. Kufuneka kwakhona ibe neqondo elithile lokugcinwa kwamanzi kunye namandla okudibanisa, akukho percolation kunye nokwahlula, kwaye ibe yi-adiabatic kunye neqondo lokushisa eliphantsi.
Udaka oluqhelekileyo lokuzilinganisa lufuna ulwelo olulungileyo, kodwa ukuhamba kodaka lwesamente okwenyani kudla ngokuba yi-10-12cm kuphela; I-cellulose ether iyona nto iphambili edibeneyo yodaka, nangona imali eyongeziweyo iphantsi kakhulu, inokuphucula kakhulu ukusebenza kodaka, okunokuphucula ukuhambelana kodaka, ukusebenza, ukusebenza ngokubambisana kunye nokugcinwa kwamanzi. Inendima ebaluleke kakhulu kwintsimi yodaka olulungeleyo.
1 Ulwelo
I-ether ye-cellulose inempembelelo ebalulekileyo ekugcineni amanzi, ukuhambelana kunye nokusebenza kodaka. Ngokukodwa njenge-self-leveling mortar, i-fluidity yenye yezibonakaliso eziphambili zokuvavanya ukusebenza kokuzilinganisa. I-fluidity ye-mortar ingahlengahlengiswa ngokutshintsha inani le-cellulose ether phantsi kwesiseko sokuqinisekisa ukubunjwa okuqhelekileyo kodaka. Umxholo ophezulu kakhulu uya kunciphisa i-fluidity of mortar, ngoko ke, isixa se-cellulose ether kufuneka ilawulwe ngaphakathi koluhlu olufanelekileyo.
2 Ukugcinwa kwamanzi
Udaka olugcina amanzi luphawu olubalulekileyo lokuzinza kwamalungu angaphakathi odaka lwesamente. Ukuze wenze i-gel imathiriyeli ye-hydrated ngokupheleleyo, isixa esifanelekileyo se-cellulose ether ingasetyenziselwa ixesha elide ukugcina amanzi kumdaka. Ngokuqhelekileyo, njengoko isixa se-cellulose ether sanda, ukugcinwa kwamanzi kwi-mortar kuyanda. Ukongezelela, i-viscosity ye-cellulose ether inefuthe elikhulu ekugcinweni kwamanzi omdaka; iphezulu i-viscosity, ngcono ukugcinwa kwamanzi.
3 Ukuseta ixesha
I-ether ye-cellulose inefuthe lokuthintela kwi-mortar. Ngokunyuka komxholo we-cellulose ether, ixesha lokumisela i-mortar liya kwandiswa. Kwaye kunye nomxholo ophezulu we-cellulose ether, isiphumo sokuqala se-hydration hysteresis yesamente ibonakala ngakumbi.
4 Amandla e-Flexural kunye namandla acinezelayo
Ngokubanzi, amandla yenye yeenqobo zovavanyo ezibalulekileyo zomxube wesamente yokunyanga imathiriyeli. Amandla oxinzelelo kunye nokuqina kwe-flexural yomdaka uya kuncitshiswa xa umxholo we-cellulose ether ukhula.
