Ingabe ukuphakama kwamanzi odaka lukakhonkolo kungcono?

Ukugcinwa kwamanzi kuyisici esibalulekile sodaka lukakhonkolo njengoba luthinta ngokuqondile ukusebenza kwalo, isikhathi sokusetha, namandla emishini. Kodwa-ke, ubudlelwano phakathi kokugcinwa kwamanzi nokusebenza kwe-plaster mortar abuqondile, futhi ayikho impendulo eqondile yokuthi ukugcinwa kwamanzi okuphezulu, kungcono yini udaka lukakhonkolo.

Ukugcinwa kwamanzi kubhekisela emandleni odaka lwe-plaster ukugcina amanzi ngaphandle kokopha noma ukuhlukaniswa. Ngokuvamile, umthamo ophezulu wokugcina amanzi usho ukuthi udaka olukhonkolo lungabamba amanzi amaningi futhi luhlale lusebenza isikhathi eside, okungaba yinzuzo kwezinye izinhlelo zokusebenza. Kodwa-ke, ukugcinwa kwamanzi ngokweqile kungaholela ezinkingeni ezinjengokuncipha, ukuqhekeka, nokunciphisa amandla emishini, okungaba nomthelela omubi ekusebenzeni kwe-plaster mortar.

Uma kuziwa ekugcinweni kwamanzi kodaka lukakhonkolo, inani elifanelekile lincike ezicini ezihlukahlukene ezifana nohlobo lwe-plaster, izinga lokushisa elizungezile kanye nomswakama, indlela yokuxuba, kanye nomphumela oyifunayo. Isibonelo, ezimeni ezishisayo nezomile, ukugcinwa kwamanzi kodaka lukakhonkolo kufanele kube phezulu ukuze kuvinjelwe ukomiswa ngokweqile, kanti emazingeni okushisa abandayo, ukugcinwa kwamanzi okuphansi kungase kunconywe ukuze kusheshiswe isikhathi sokusetha.

Enye yezinzuzo eziyinhloko zokugcinwa kwamanzi okuphezulu kudaka olukhonkolo ukuthi kungathuthukisa ukusebenza, kwenze kube lula ukusabalala nokushelela ngaphezulu. Lokhu kungaba yinzuzo ezinhlelweni zokusebenza lapho kufiswa khona ukushelela nokuze kube sekugcineni, njengokukhonkoloza kokuhlobisa noma ukulungisa izindonga noma uphahla olulimele. Ukugcinwa kwamanzi okuphakeme kungase futhi kuthuthukise isibopho phakathi kwe-plaster mortar kanye ne-substrate, okwandisa amandla ayo wonke.

Kodwa-ke, ukugcinwa kwamanzi ngokweqile kungaholela ezinkingeni ezifana nokuqhekeka, ukuncipha, nokunciphisa amandla emishini. Uma udaka olukhonkolo lunamanzi amaningi, kungase kuthathe isikhathi eside ukusetha nokuqina, okungaholela ekuqhekekeni nasekushwabaneni. Ukwengeza, amanzi engeziwe angase enze buthaka isibopho phakathi kodaka lwe-plaster kanye ne-substrate, okunganciphisa amandla awo wonke kanye nokuqina.

Ukuze kuzuzwe ukugcinwa kwamanzi okufanelekile ku-plaster mortar, izithasiselo ezihlukahlukene zingasetshenziswa. Isibonelo, ukwengeza ama-cellulose ethers, njenge-methyl cellulose noma i-hydroxypropyl methylcellulose, kungathuthukisa ukugcinwa kwamanzi ngaphandle kokuphazamisa amandla okusebenza. Ezinye izithasiselo ezifana ne-air-entraining agents zingasetshenziswa ukwandisa ukusebenza nokunciphisa ingozi yokuqhekeka nokuncipha.

Kafushane, ubudlelwano phakathi kokugcinwa kwamanzi nokusebenza kodaka olukhonkolo kuyinkimbinkimbi, futhi ayikho impendulo elingana nosayizi owodwa yokuthi ukugcinwa kwamanzi okuphezulu kungcono yini. Ukugcinwa kwamanzi okufanelekile kuncike ezintweni ezihlukahlukene, futhi kufanele kube nokulinganisela phakathi kokusebenza, isikhathi sokusetha, namandla okusebenza. Ngokuqonda izakhiwo ze-plaster mortar nokusebenzisa izithasiselo ezifanele, kungenzeka ukufeza ukugcinwa kwamanzi okuphelele kwesicelo esinikeziwe.
