I-self-leveling mortar inokuxhomekeka kubunzima bayo ukwenza isiseko esisicaba, esigudileyo kunye nesiqinileyo kwi-substrate yokubeka okanye ukudibanisa ezinye izinto. Isenokwenza ulwakhiwo olusebenzayo kwindawo enkulu. Ubumanzi obuphezulu luphawu olubaluleke kakhulu lodaka lokuzilinganisa. ; Ukongezelela, kufuneka kwakhona kube nokugcinwa kwamanzi athile kunye namandla okubambisana, kungavelisi ulwahlulo lwamanzi, kwaye kube neempawu zokushisa ukushisa kunye nokunyuka kweqondo lokushisa eliphantsi.
Ngokubanzi, udaka oluzilinganisa ngokwalo lufuna ubumanzi obulungileyo.Iselulosi ethersisongezo esikhulu sodaka olusele luxutywe. Nangona imali yokongeza iphantsi kakhulu, inokuphucula kakhulu ukusebenza kodaka. Inokuphucula ukuhambelana, ukusebenza komsebenzi, kunye neempawu zokubambelela kunye neempawu zokugcina amanzi, njl. Idlala indima ebalulekileyo kwintsimi yodaka oluxutywe ngokulungeleyo.
Ubumanzi
Iselulosi etherkunempembelelo ebalulekileyo kugcino lwamanzi, ukungaguquguquki, kunye nokusebenza kolwakhiwo lodaka lokuzilinganisa. Ngokukodwa kwi-self-leveling mortar, i-fluidity yenye yezibonakaliso eziphambili zokuvavanya ukusebenza kokuzilinganisa. Kwisiseko sokuqinisekisa ukubunjwa okuqhelekileyo kodaka, ukunyanzeliswa kodaka kunokulungiswa ngokutshintsha inani le-cellulose ether. Nangona kunjalo, idosi ephezulu kakhulu iyakunciphisa ukumanzi kodaka, ngoko ke idosi ye-cellulose ether kufuneka ilawulwe kuluhlu olufanelekileyo.
Ukugcinwa kwamanzi
Ukugcinwa kwamanzi ngodaka luphawu olubalulekileyo lokulinganisa uzinzo lwamalungu angaphakathi odaka lwesamente entsha. 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 kumxholo we-cellulose ether. Umsebenzi wokugcinwa kwamanzi we-cellulose ether unokuthintela i-substrate ekufunxeni amanzi amaninzi 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 enkulu ekugcinweni kwamanzi omdaka. Ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi. I-cellulose ethers kunye ne-viscosity jikelele ye-400 mpa.s isetyenziswa kakhulu kwi-self-leveling mortars, enokuphucula ukusebenza komgangatho wodaka kunye nokuphucula ubuninzi bomdaka.
Ixesha le-coagulation
Iselulosi etherinesiphumo esithile sokunciphisa udaka. Njengoko umxholo we-cellulose ether ukhula, ixesha lokumisela lomdaka landa. Isiphumo esibambekayo se-cellulose ether kudaka lwesamente ikakhulu sixhomekeke kwiqondo lokutshintshwa kwamaqela e-alkyl kwaye inobudlelwane obuncinane kunye nobunzima bayo bemolekyuli. Incinci idigri ye-alkyl endaweni, kokukhona umxholo omkhulu we-hydroxyl, kwaye ubonakala ngakumbi isiphumo sokubambezela. Kwaye okukhona uphezulu umxholo we-cellulose ether, kokukhona kucaca ngakumbi umaleko wefilimu ontsonkothileyo ekubambezeleni ukuhanjiswa kwangaphambili kwesamente, kwaye ke ngoko, kokukhona kubonakala ngakumbi isiphumo sokubambezela.
Amandla e-Flexural kunye namandla oxinzelelo
Amandla sesinye sezibonakaliso ezibalulekileyo zovavanyo lwesiphumo sokuqina kwezinto zesamente esekwe kwisamente kumxube. Njengoko umxholo we-cellulose ether ukhula, amandla oxinzelelo kunye namandla okuguquguquka kodaka luya kuncipha. Kufuneka ilawulwe kuluhlu oluthile olufanelekileyo.
Amandla okudibanisa
I-ether ye-cellulose inempembelelo enkulu kwiipropati zokudibanisa udaka. I-cellulose ether yenza ifilimu ye-polymer enefuthe lokutywinwa phakathi kweengqungquthela ze-cement hydration kwinkqubo yesigaba se-liquid, ekhuthaza amanzi amaninzi kwifilimu ye-polymer ngaphandle kweengqungquthela ze-cement, ezihambelana ne-hydration epheleleyo ye-samente, ngaloo ndlela iphucula amandla e-Bond. emva kokuqina kodaka. Kwangaxeshanye, isixa esifanelekileyo se-cellulose ether sonyusa iplastikhi kunye nokuguquguquka kodaka, kunciphisa ukuqina kwendawo yokutshintsha phakathi kodaka kunye nesiseko sezinto, kwaye kunciphisa isakhono sokutyibilika phakathi kojongano. Ukuya kumlinganiselo othile, umphumo wokudibanisa phakathi kodaka kunye nesiseko sezinto zongezwa. Ukongezelela, ngenxa yobukho be-cellulose ether kwi-sement slurry, indawo ekhethekileyo yokutshintshwa kwendawo kunye ne-interface layer yenziwa phakathi kweengqungquthela zodaka kunye neemveliso ze-hydration. Lo maleko we-interface wenza ukuba indawo yenguqu yojongano ibe bhetyebhetye kwaye ibe ngqongqo esezantsi. Ngoko ke, , ukuze udaka lunamandla okudibanisa okuqinileyo.
