Udaka lokwakha lusetshenziswa kakhulu ezintweni ezehlukene embonini yezokwakha njengokupulasitela, ukubeka phansi phansi, uthayela kanye nokwakha, njll. Udaka ngokuvamile luyingxube usimende, isihlabathi namanzi okuxutshwe ukwenza unamathisele.Eminyakeni yamuva nje, kuye kwaba nesidingo esikhulayo sezithasiselo ezithuthukisa ukusebenza kodaka.I-Redispersible polymer powder (RDP) iyisengezo esithandwayo esifakwa odakeni lokwakha ukuze kuthuthukiswe izakhiwo zabo.Lesi sihloko sizohlinzeka ngokubukezwa kwendima ye-RDP redispersible polymer powder additives kuma-mortars wokwakha.
I-redispersible polymer powder iyi-polymer eyakhiwe nge-ethylene-vinyl acetate copolymer, i-acrylic acid ne-vinyl acetate.Lawa ma-polymer axubene nezinye izithasiselo ezinjengama-filler, ama-thieners nama-binders ukuze kukhiqizwe izimpushana ze-RDP.Izimpushana ze-RDP zisetshenziswa ekukhiqizeni izinhlobonhlobo zezinto zokwakha ezihlanganisa izinto zokunamathisela zamathayela, udaka olusekelwe kusimende nama-ejenti okulinganisa.
Enye yezinzuzo eziyinhloko zokusebenzisa i-RDP emigodini yokwakha ukuthi ithuthukisa ukusebenza kodaka.I-RDP inyusa ukuhambisana kodaka, okwenza kube lula ukuyifaka nokusabalala.Ukucutshungulwa okuthuthukisiwe nakho kusho ukuthi amanzi amancane adingekayo ukuze kuzuzwe ukuvumelana okufunayo.Lokhu kwenza udaka lumelane kakhulu nokuqhekeka nokushwabana, kulwenze luqine futhi luhlale isikhathi eside.
Enye inzuzo ebalulekile yokusebenzisa i-RDP kumasimende wokwakha ukuthi ithuthukisa ukunamathela kodaka.Ukunamathela okuthuthukisiwe kusho ukuthi udaka lwakha isibopho esiqinile nengaphezulu ukuze sisebenze kangcono futhi siqine.I-RDP iphinde ithuthukise izindawo zokugcina amanzi edaka, isiza ukuvimbela ukulahleka kwamanzi ngesikhathi sokwakha.Lokhu kuvumela udaka ukuthi lusethe futhi luqine ngokulinganayo, luqinisekise ukusebenza okungaguquki nokuqina.
I-RDP iphinde ikhulise ukuguquguquka kodaka, iyenze ikwazi kangcono ukumelana nengcindezi yesikhathi eside kanye nobunzima.Ukunwebeka okuguquguqukayo kodaka kusho ukuthi akulula ukuqhekeka nokuphuka ngisho nalapho ubhekene nezimo zemvelo ezinzima.Lokhu kuvumelana nezimo okuthuthukisiwe kuphinde kusho ukuthi udaka luguquguquka kakhulu futhi lungasetshenziswa kuhlelo olubanzi lwezinhlelo zokusebenza, okuhlanganisa izindawo ezingalingani nezigobile.
Ukusetshenziswa kwe-RDP kudaka lokwakha nakho kwandisa amandla okucindezela odaka.Amandla acindezelayo ayimpahla ebalulekile yokwakha udaka njengoba enquma ukuthi udaka lumelana kanjani nokuguquguquka nokuqhekeka ngaphansi komthwalo.I-RDP inyusa amandla acindezelayo odaka, iyenze ikwazi kangcono ukumelana nemithwalo esindayo futhi inciphise amathuba okuqhekeka nokulimala.
Kafushane, ukusetshenziswa kwe-RDP redispersible polymer powder additives in the building mortars kunikeza uhla lwezinzuzo ezingathuthukisa ukusebenza nokuqina kodaka.I-RDP ithuthukisa ukusebenza, ukunamathela, ukugcinwa kwamanzi, ukuguquguquka kanye namandla acindezelayo odaka, iyenze ibe nezinto ezihlukahlukene futhi ifanele uhla olubanzi lwezinhlelo zokusebenza.Ukusebenzisa i-RDP osikeni bokwakha kukhiqiza umkhiqizo osebenza kahle kakhudlwana, ongabizi kakhulu futhi ohlala isikhathi eside, okwenza kube ukukhetha okuthandwa kakhulu kubakhi nosonkontileka.
