ethula
Udaka luyimpahla yokwakha esetshenziselwa ukuhlanganisa nokugcwalisa izikhala phakathi kwezitini, amabhlogo kakhonkolo, nezinye izinto zokwakha ezifanayo.Ngokuvamile iqukethe ingxube usimende, isihlabathi namanzi.Kodwa-ke, ama-mortars angabuye ashintshwe ngokwengeza ama-cellulose ethers, athuthukisa ukungaguquguquki kwempahla kanye nezakhiwo zokulwa ne-sag.
Ama-cellulose ether ama-polymers ancibilika emanzini atholakala ku-cellulose, i-carbohydrate yemvelo etholakala ezitshalweni.Zivame ukusetshenziswa ezintweni zokwakha njengama-thickeners, ama-stabilizer nama-ejenti okugcina amanzi.Ama-cellulose ethers atholakale esebenza ngempumelelo ekuthuthukiseni izakhiwo zodaka, okuhlanganisa ukusebenza, amandla kanye nokuqina.
Kulesi sihloko sizoxoxa ngokusetshenziswa kwe-cellulose ethers kuma-mortars kanye nomthelela wabo ekuvumelaneni nokuphikiswa kwe-sag.
Ukuvumelana kodaka
Ukungaguquguquki kodaka kubhekisela ekhonweni lalo lokuma, ukubumba nokusabalalisa ngaphandle kokuqhekeka noma ukugoqa.Kuyisici esibalulekile esinquma kalula ukusetshenziswa kanye nekhwalithi yomkhiqizo oqediwe.Udaka olungaguquki luzohlangana ngokuqinile nangokulinganayo ezintweni zokwakha, kwakheka isakhiwo esizinzile nesiqinile.
Kodwa-ke, ukuthola ukwakheka kodaka okulungile kungaba inselele, ikakhulukazi uma impahla yokwakha inendawo engalingani noma umumo.Lena inzuzo yokusebenzisa ama-cellulose ethers.
Ama-cellulose ethers angathuthukisa ukuhambisana kodaka ngokwandisa umthamo wento ebamba amanzi.Lapho ama-cellulose ether engezwa engxubeni yodaka, amunca umswakama futhi akhe into efana nejeli ehlanganisa ezinye izinto ndawonye.Le nto efana nejeli isiza nasekunciphiseni ukushwabana kodaka, ngaleyo ndlela kuncishiswe imifantu kanye nezikhala kumkhiqizo oqediwe.
Izakhiwo ze-anti-sag zodaka
I-sag resistance of mortar ibhekisela ekhonweni layo lokugcina isimo sayo futhi igweme ukwehla lapho isetshenziswa ngokuqondile.Ezinye izinto zokwakha, njengamabhlogo kakhonkolo, zinezindawo ezimaholoholo ezidinga izingqimba eziwugqinsi zodaka ukuze kuqinisekiswe isibopho esiqinile.Uma udaka olusetshenzisiwe luntula ukumelana ne-sag, luzoshelela ukusuka phezulu, ludale izikhala futhi lunciphise amandla ebhondi.
Ama-cellulose ether angathuthukisa ukumelana nodaka ngokukhulisa i-viscosity noma ukujiya kwawo.Le viscosity isiza udaka ukuthi lugcine ukwakheka kwalo lapho lusetshenziswa endaweni eqondile, luvimbele ukuthi lungasheleli noma luhlehle.Ngaphezu kwalokho, ama-cellulose ethers asebenza njengamafutha, okwenza udaka lusakazeke kalula, ngisho nasezindaweni ezimahhadlahhadla.
Ekuphetheni
Ukusetshenziswa kwe-cellulose ethers odakeni kutholwe kuthuthukisa ukungaguquguquki kwezinto kanye nokumelana nokuntenga.Ama-cellulose ethers akhuphula umthamo wokubamba amanzi wodaka, okuholela ekutheni kube yinto engaguquki ehlangana ngokulinganayo ezintweni zokwakha.Ngaphezu kwalokho, i-cellulose ethers ingathuthukisa ukumelana ne-sag ye-mortar ngokukhulisa i-viscosity yayo, ukuyivumela ukuthi igcine ukuma kwayo lapho isetshenziswa ezindaweni eziqondile.
Sekukonke, ukufakwa kwe-cellulose ethers emathangeni kuyisinyathelo esihle emkhakheni wezokwakha, okuvumela ukuhlangana okungcono, ukuzinza okukhulu kanye nokwakhiwa kwekhwalithi ephezulu.
