Yiziphi izidingo zobuchwepheshe zodaka lokuphamba?

Plastering mortar, also known as plaster or render, is a mixture of cementitious materials, aggregates, water, and additives used for coating and finishing interior and exterior walls and ceilings. Izidingo zobuchwepheshe zodaka ngodaka ziyahlukahluka ngokuya ngezinto ezifana ne-substrate, indlela yesicelo, izimo zemvelo kanye nokuqedwa okufunayo. Kodwa-ke, ezinye izidingo zobuchwepheshe ezivamile zifaka:

1. Adhesion: Udaka oluphambanisa kufanele anamathele ku-substrate, aqinisekise isibopho esiqinile phakathi kodaka nangaphezulu. Ukunamathelisa okufanele kuvimbela ukudilizwa, ukuqhekeka, noma ukuvalwa kodaka kusuka ku-substrate ngokuhamba kwesikhathi.
2. Ukusetshenziswa: Udaka oluphambayo kufanele ube nokusebenza okuhle, ukuvumela ukuthi kusetshenziswe kalula, ukusakazeka, futhi kwasebenza kuphela ngamapulangwe. Udaka kufanele abe ngopulasitiki futhi ahlehlise, avuse uhlelo lokusebenza olubushelelezi futhi olufanayo ngaphandle kokugcotshwa ngokweqile, ukushefa, noma ukuqhekeka.
3. Ukungaguquguquki: Ukuvumelana kodaka oluphambayo kufanele kube khona ngendlela yesicelo kanye nokuqedwa okufisayo. Udaka kufanele kube lula ukuxuba nokulungisa ukufeza ukugeleza okufisayo, ukuthungwa, nokumboza engxenyeni engezansi.
4. Ukubeka isikhathi: Udaka oluphambile kufanele ube nesikhathi esilawulwayo sokusetha esivumela isikhathi esanele sohlelo lokusebenza, ukukhohlisa nokuqeda ngaphambi kokuba udaka luqale ukwenza lukhuni. Isikhathi sokusetha kufanele silungele izidingo zephrojekthi, sivumela inqubekela phambili yomsebenzi ofanele ngaphandle kokuyekethisa ikhwalithi yokuqeda.
5. Amandla: Udaka oluphambanisa kufanele athuthukise amandla anele ngemuva kokuhlelwa futhi aphule ukumelana nezingcindezi nemithwalo ehlangane nayo ngesikhathi sokuphila kwenkonzo. Udaka kufanele abe namandla anele okucindezela ukusekela isisindo sawo futhi amelane nokuguquguquka noma ukuqhekeka ngaphansi kwemithwalo yangaphandle.
6. Ukuqina: Udaka oluphambayo kufanele luhlale luhlala isikhathi eside futhi lumelane nokuwohloka, isimo sezulu, kanye nezici zezemvelo ezifana nomswakama, ukuguquguquka kwezinga lokushisa, nokuvezwa kwamakhemikhali. Uhlamvu oluqinile luqinisekisa ukusebenza kwesikhathi eside futhi lunciphise isidingo sokulungiswa noma ukulungiswa.
7. Ukugcinwa kwamanzi: Udaka oluphambanisa kufanele ugcine amanzi ngempumelelo ngesikhathi senqubo yokuhlelwa kanye nokwelapha ukukhuthaza i-hydration yezinto zokwakha dementile futhi uthuthukise amandla e-bond kanye nokunamathela. Ukugcinwa kwamanzi okulungile kuthuthukisa ukusebenza futhi kunciphisa ubungozi be-shrinkage, ukuqhekeka, noma iziphene ezingaphezulu.
8. Ukulawulwa kweShrinkage: Udaka oluphambayo kufanele lubonise ukushwabana okuncane ngesikhathi sokomiswa nokuyelapheka ukuvikela ukwakheka kwemifantu noma ukungapheleli komhlaba. Izithasiselo noma amasu okulawula i-shrinkage asetshenziselwa ukunciphisa i-shrinkage futhi aqinisekise ukuqeda okubushelelezi, okufanayo.
9. Ukuvumelana: udaka oluphambayo kufanele luhambisane ne-substrate, izinto zokwakha, nezinto zokuqeda ezisetshenzisiwe kuphrojekthi. Ukuvumelana kuqinisekisa ukunamathela okufanele, amandla e-bond, kanye nokusebenza kwesikhathi eside kohlelo lwe-plaster.
10. Ama-aesthetics: Udaka oluphambayo kufanele akhiqize ukuqeda okubushelelezi, umfaniswano, kanye nokuqedwa okujabulisayo okuhlangabezana nokuklama kanye nezidingo zokwakha zephrojekthi. Udaka kufanele lukwazi ukufeza ukwakheka okufiselekayo, imibala, kanye nemibala ebunjiwe ukuthuthukisa ukubukeka kwezindonga noma ophahleni.

Ngokuhlangabezana nalezi zidingo zobuchwepheshe, udaka olwaluphawula anganikeza ukuqeda okuhlala isikhathi eside, okuhehayo, okuphezulu kwekhwalithi ephezulu yezindawo ezingaphakathi nangaphandle ezindaweni zokuhlala, ezentengiso, nakuma-Industrial zokwakha. Abakhiqizi bakha ngokucophelela ngodaka olubusayo ukuze baqinisekise ukuthi bahlangabezana nalezi zindlela futhi benze ngokwenele ezinhlobonhlobo zezicelo nezimo zemvelo.
