Udaka oluxubeneyo olomileyo lusetyenziswa ngokubanzi kwiiprojekthi zokwakha ngenxa yokuba lula kunye nokusebenza ngokufanelekileyo. Ibandakanya indibaniselwano yesamente, isanti, kunye nezinye izongezo, ezifana ne-cellulose ether, edlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokupheleleyo kodaka. Ngokukodwa, i-cellulose ether, ekwabizwa ngokuba yiHydroxypropyl Methyl Cellulose (HPMC), isetyenziselwa ukuphucula umthamo wogcino lwamanzi kudaka olomileyo oluxutyiweyo, nto leyo eyandisa ukuhambelana nokusebenza kwayo.
Amanzi abalulekile kwinkqubo yokufakwa kwamanzi kwisamente, apho athi adibane namasuntswana esamente enze iqhina eliqinileyo elithi ekugqibeleni libe lukhuni udaka. Nangona kunjalo, ukukhuphuka kwamanzi amaninzi ngexesha lokumisa okanye ukuseta inkqubo kunokukhokelela kwimiba efana nokuqhekeka, ukuncipha, kunye nokunciphisa amandla. Apha kulapho i-cellulose ether ingena khona. Ngokudibanisa i-cellulose ether kudaka olomileyo oluxutyiweyo, umthamo wogcino lwamanzi uphuculwa ngokubonakalayo, ngokufanelekileyo uthomalalisa iimpembelelo ezingalunganga zokumka kwamanzi ngokukhawuleza.
Kwi-mortar edibeneyo eyomileyo, i-cellulose ether isebenza njenge-ejenti yokubamba amanzi, evumela ukuba i-hydration ende ye-cement particles. Le nkqubo ye-hydration eyandisiweyo iqinisekisa ukuba udaka lunexesha elaneleyo lokuphuhlisa amandla afanelekileyo kunye nokuqina. Iimolekyuli ze-cellulose ether zenza umaleko okhuselayo ojikeleze amasuntswana e-samente, ukunciphisa izinga lokunyuka kwamanzi kunye nokwandisa ukufumaneka kwamanzi kwi-hydration. Ngenxa yoko, ukuhambelana kodaka kuphuculwe, okwenza kube lula ukusabalalisa, ukubumba, kunye nokumila ngexesha lokusetyenziswa.
Ngaphaya koko, i-cellulose ether yonyusa ukusebenza kodaka oluxutyiweyo olomileyo. Isebenza njenge-lubricant, inciphisa ingxabano phakathi kwezinto zodaka kwaye yenza ukuba usetyenziso olulula. Oku kuphucuka kokusebenza akugcini nje ukwandisa imveliso kodwa kwandisa umgangatho uwonke wokwakhiwa okugqityiweyo. Ukusetyenziswa kwe-cellulose ether kwimori edibeneyo eyomileyo kunciphisa umngcipheko wokwahlula, apho izinto ezidibeneyo zihlukana ngexesha lokuthutha okanye ukusetyenziswa. Oku kuqinisekisa umxube we-homogenous kunye nokusebenza okuhambelanayo kodaka.
Ukongeza, i-cellulose ether yokugcina amanzi inceda ekulawuleni inkqubo yokunyanga udaka. Unyango olululo lubalulekile ukuze kuphunyezwe amandla afunekayo okugqibela kunye nokuqina kwemathiriyeli yokwakha. I-hydration yexesha elide enikezelwa yi-cellulose ether iqinisekisa ukuba i-mortar iphilisa ngokulinganayo kwaye ngokucokisekileyo, isusa iindawo ezibuthathaka ezinokuthi ziphucule ukusebenza kwexesha elide.
Kuyafaneleka ukuba uqaphele ukuba indima ye-cellulose ether kwi-mortar edibeneyo eyomileyo ayiphelelanga ekugcinweni kwamanzi kuphela. Olu longezo oluguquguqukayo lunikeza ezinye iingenelo, ezifana nokubambelela okuphuculweyo, ukunciphisa ukuqhekeka, kunye nokwanda kokuchasana kwimozulu kunye neekhemikhali. Ke ngoko, ithathwa njengecandelo elibalulekileyo ekwenziweni komgangatho ophezulu wodaka oluxutyiweyo olomileyo.
Ukuqukumbela, ukugcinwa kwamanzi e-cellulose ether kudlala indima ebalulekileyo ekusebenzeni kodaka oluxubileyo olomileyo. Iphucula ukufumaneka kwamanzi kwi-samente hydration, iphucula ukungaguquguquki kodaka, ukusebenza, kunye nomgangatho uwonke wemathiriyeli yokwakha. Ukufakwa kwe-cellulose ether kuqinisekisa ukuhanjiswa kwexesha elide, kunciphisa ukukhuphuka kwamanzi, kunye nokuncedisa ekulawuleni inkqubo yokunyanga. Ngenxa yoko, udaka olomileyo oluxutyiweyo olune-cellulose ether lunika ukusebenza okuphezulu, ukuqina, kunye nokomelela kwiiprojekthi zokwakha.
