I-Masonry iyisici esibalulekile nesiyisisekelo sokwakhiwa osekungamakhulu eminyaka ikhona. Kubandakanya ukusebenzisa izitini, itshe, nezinye izinto zokwakha izakhiwo ezihlala isikhathi eside neziqinile. Ukuqinisekisa izinga eliphezulu lodaka lwamatshe, izithasiselo ezihlukahlukene zisetshenziselwa ukwandisa amandla ayo nokusebenza. Esinye sezengezo esinjalo i-cellulose ether, okutholwe ukuthi iyasebenza ekuxubeni inqwaba yodaka lwamatshe. Leli phepha lixoxa ngezakhiwo kanye nezinzuzo ze-cellulose ether ehlanganisiwe ye-masonry mortar.
Ama-cellulose ethers atholakala emicu yezitshalo futhi ngokuvamile asetshenziswa emkhakheni wokwakha njengezithasiselo ezintweni zokwakha ezisekelwe kusimende. Yenziwe nge-cellulose yemvelo eshintshwe amakhemikhali ukuze kuthuthukiswe izici zayo. I-Cellulose ether iyi-polymer encibilika emanzini engangezwa ezigabeni ezihlukene zokulungiswa kodaka ukuze kuthuthukiswe ukusebenza kodaka. Kunezinhlobo ezahlukene ze-cellulose ethers, okuhlanganisa i-methylhydroxyethylcellulose (MHEC), i-ethylhydroxyethylcellulose (EHEC), ne-hydroxyethylcellulose (HEC), phakathi kwezinye.
Ukusebenza kwe-cellulose ether ehlanganisiwe ye-masonry mortar
Thuthukisa ukusebenza
Enye yezinzuzo eziyinhloko zokusebenzisa ama-cellulose ethers odakeni lwe-masonry oluhlanganisiwe ukuthuthukiswa kokusebenza. Ama-cellulose ethers asebenza njengamafutha, anciphisa ukungqubuzana phakathi kodaka nezinye izinto. Lokhu kwenza udaka lusakazeke kalula, kunciphisa isikhathi sokwakha nokwandisa umkhiqizo. Ngaphezu kwalokho, i-cellulose ether ingakhuphula ukuhambisana kwengxube, yenze ukusabalalisa kodaka kube bushelelezi futhi kufane kakhulu.
ukwandisa ukugcinwa kwamanzi
I-cellulose ether iyi-hydrophilic, okusho ukuthi inokuhambisana namanzi. Uma yengezwe odakeni oluhlanganisiwe lwe-masonry, ingakhuphula ukugcinwa kwamanzi kodaka. Lokhu kusiza ukugcina udaka lunomswakama isikhathi eside, okubalulekile enqubweni yokwelapha. Ukwelashwa okufanele kuqinisekisa ukuthi udaka lufinyelela amandla alo aphezulu, okwenza luqine futhi luhlale isikhathi eside.
nciphisa ukuncipha
Enye inzuzo yokusebenzisa ama-cellulose ethers kuma-masonry aggregate aggregate mortars ukunciphisa ukuncipha. Ukuncipha kwenzeka lapho udaka loma futhi lulahlekelwa umswakama, okubangela ukuba lunciphe. Lokhu kungaholela ekuqhekekeni nokunye ukukhubazeka esakhiweni esiphelile. Ama-cellulose ethers asiza ukunciphisa inani lamanzi ahwamukayo odakeni, ngaleyo ndlela anciphise ukuncipha nokuthuthukisa ikhwalithi yonke yephrojekthi eqediwe.
thuthukisa ukunamathela
Ukunamathela okuhle phakathi kwamayunithi odaka namatshe kubalulekile ukuze kube nesakhiwo esiqinile nesihlala isikhathi eside. Ama-cellulose ethers athuthukisa ukunamathela kodaka ngokuxhumanisa izinhlayiya zikasimende. Lokhu kuthuthukisa izakhiwo zokunamathisela zodaka, okuholela ekwakhekeni okuqinile, okuthembekile.
ukwandisa ukuguquguquka
Izakhiwo zamatshe ezihlanganisiwe ezihlanganisiwe zisengozini yokuqhekeka ngenxa yezinto zangaphandle ezifana nokushintsha kwezinga lokushisa, umswakama, nezinye izimo zemvelo. I-cellulose ether kudaka oluhlanganisiwe lwe-masonry isiza ukuthuthukisa ukuguquguquka kodaka. Lokhu kwenza kungabi lula ukuphuka futhi kusiza ekugcineni ubuqotho besakhiwo sephrojekthi.
Ekuphetheni
Kafushane, kunezinzuzo ezimbalwa zokusebenzisa ama-ether e-cellulose kuzisindo zamatshe ezihlanganisiwe ezihlanganisiwe. Ithuthukisa ukusebenza kahle, ithuthukisa ukugcinwa kwamanzi, inciphisa ukushwabana, ikhulise ukunamathela futhi ithuthukise ukuguquguquka. Uma esetshenziswa ngendlela efanele, ama-cellulose ether angathuthukisa ikhwalithi iyonke kanye nokuqina kwezakhiwo zamatshe ezihlanganisiwe ezihlanganisiwe. Kuyisithasiselo esinobungani nemvelo futhi esingabizi kakhulu esingasetshenziswa ezinhlobonhlobo zamaphrojekthi wokwakha. Ngakho-ke, osonkontileka nabakhi kufanele bacabangele ukusebenzisa ama-cellulose ethers odakeni oluhlanganisiwe lwe-masonry.
