Udaka oluzilinganisa ngokwalo lunokuxhomekeka kubunzima balo ukwenza isiseko esisicaba, esigudileyo, kwaye esomeleleyo kwisubstrate yokubeka okanye ukudibanisa ezinye izinto, kwaye inokuqhuba ulwakhiwo olukhulu nolusebenzayo. Ke ngoko, ulwelo oluphezulu luphawu olubaluleke kakhulu lokuzilinganisa udaka; Ukongezelela, kufuneka kwakhona ibe neqondo elithile lokugcinwa kwamanzi kunye namandla okudibanisa, ngaphandle kokwenzeka kokuhlukana kwamanzi, kwaye ibe neempawu zokugquma kunye nokunyuka kweqondo lokushisa eliphantsi. Ngokubanzi, udaka lokuzilinganisa lufuna ubumanzi obulungileyo, kodwa olona daka lwesamente ludla ngokuba yi-10-12cm kuphela; I-ether ye-cellulose iyona nto yokongeza kwi-mortar esele ixutywe. Nangona imali eyongeziweyo iphantsi kakhulu, inokuphucula kakhulu ukusebenza kodaka. Inokuphucula ukuhambelana, ukusebenza, ukusebenza ngokubambisana, kunye nokugcinwa kwamanzi omdaka. Idlala indima ebaluleke kakhulu kwintsimi yodaka oluxutywe ngaphambili.
1. Ubumanzi
I-ether yeCellulose inempembelelo ebalulekileyo kugcino lwamanzi, ukungaguquguquki, kunye nokusebenza kolwakhiwo lodaka lokuzilinganisa. Ngokukodwa njengodaka lokuzilinganisa, ukuqukuqela sesinye sezalathisi eziphambili zokuvavanya ukusebenza komgangatho wesiqu sakho. Kwisiseko sokuqinisekisa ukubunjwa okuqhelekileyo kodaka, ukunyanzeliswa kodaka kunokulungiswa ngokutshintsha idosi ye-cellulose ether. Nangona kunjalo, idosi egqithisileyo inokunciphisa ubumanzi bodaka, ngoko ke idosi ye-cellulose ether kufuneka ilawulwe kuluhlu olufanelekileyo.
2. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi odaka luphawu olubalulekileyo lokulinganisa uzinzo lwamalungu angaphakathi odaka lwesamente esandula ukuxutywa. Ukuze wenze izinto ze-gel zizaliswe ngokupheleleyo, isixa esifanelekileyo se-cellulose ether sinokugcina ukufuma kwi-mortar ixesha elide. Ngokuqhelekileyo, izinga lokugcinwa kwamanzi kwi-slurry liyenyuka ngokunyuka kwe-cellulose ether content. Ukugcinwa kwamanzi kwisiphumo se-cellulose ether kunokuthintela i-substrate ekufunxeni amanzi kakhulu okanye ngokukhawuleza, kwaye ithintele ukuphuphuma kwamanzi, ngaloo ndlela iqinisekisa ukuba indawo ye-slurry ibonelela ngamanzi aneleyo kwi-cement hydration. Ukongezelela, i-viscosity ye-cellulose ether nayo inempembelelo ebalulekileyo ekugcinweni kwamanzi omdaka. Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi. I-ether ye-cellulose ene-viscosity jikelele ye-400mpa. s isetyenziswa ngokuqhelekileyo kwi-self-leveling mortar, enokuphucula ukusebenza komgangatho kunye nokuqina kodaka.
