ethula
I-redispersible polymer powder (RDP) iyimpushana emhlophe encibilika kalula emanzini.Yenziwe nge-polymer emulsion spray-yomiswe ngenqubo ekhethekile.I-RDP isetshenziswa kabanzi emkhakheni wezokwakha ngenxa yokusebenza kwayo okuhle kakhulu, okungathuthukisa ukusebenza kwezinto zikasimende.Kulokhu okuthunyelwe, sizoxoxa ngamakhono e-RDP okuthuthukisa i-Mortar.
Imisebenzi ye-RDP
1. Thuthukisa izakhiwo zemishini
I-RDP ingathuthukisa izakhiwo zemishini yezinto zikasimende, okuhlanganisa amandla acindezelayo, amandla aguquguqukayo namandla aqinile.Lokhu kungenxa yokuthi uma i-RDP ixutshwe nosimende, ingakha isakhiwo esiminyene futhi esiminyene, esingathuthukisa ukunamathela phakathi kwezinhlayiya futhi kunciphise i-porosity yezinto.Ngakho-ke, kungaba ngcono ngempumelelo izakhiwo mechanical of materials.
2. Khulisa ukubumbana
Ukuhlangana phakathi kwezinhlayiya zodaka kuhlobene eduze ne-viscosity yayo.Ukuphakama kwe-viscosity, kuyanda ukuhlangana phakathi kwezinhlayiya.Lokhu kubaluleke kakhulu ngodaka lwamatshe njengoba kuqinisekisa ukuthi udaka ngeke lugezeke noma lugeleze ngesikhathi sokwakha.I-RDP ingakhuphula kakhulu i-viscosity yodaka, ngaleyo ndlela ikhulise amandla ahlangene phakathi kwezinhlayiya futhi iqinisekise ikhwalithi yephrojekthi yamatshe.
3. Thuthukisa ukugcinwa kwamanzi
Ukugcinwa kwamanzi kuyimpahla ebalulekile yodaka.Kuchazwa njengekhono lempahla yokugcina amanzi ngaphakathi kwe-matrix yayo.Uma ukugcinwa kwamanzi kunganele, udaka loma ngokushesha, okuzothinta ukusebenza kwalo futhi lunciphise amandla alo.I-RDP ingathuthukisa kakhulu ukugcinwa kwamanzi odaka, ivimbele ukuthi lome ngokushesha, futhi iqinisekise ukusebenza kahle.
4. Thuthukisa ukusebenza
Ukusebenza kubhekisela emandleni odaka okwakhiwa kalula futhi akheke.Ukusebenza kodaka kuhlobene eduze nokuvumelana kwayo, i-viscosity nokusebenza kokugcinwa kwamanzi.I-RDP ingathuthukisa kakhulu ukusebenza kodaka ngokwandisa ukungaguquguquki kwayo kanye nokubonakala kwayo.Ingase futhi inikeze izakhiwo ezinhle zokugcina amanzi, ezingaqinisekisa ukusebenza kodaka isikhathi eside.
5. Yehlisa ukuqhekeka
Ukuqhekeka kuyinkinga evamile ngezinto ezisekelwe kusimende.Ibangelwa izici eziningi, njengezinga lokushwabana kwempahla, indlela yokusetshenziswa, izimo zemvelo, njll. I-RDP inganciphisa ingozi yokuqhekeka ngokwandisa ukuguquguquka nokuguquguquka kwezinto.Ingase futhi inikeze ukunamathela okuhle phakathi kwezinhlayiya, ezinganciphisa ukuqoqwa kokucindezeleka ezintweni futhi kuvimbele ukuqhekeka.
6. Ukuqina okuthuthukisiwe
Ukuqina kusho ikhono lempahla ukumelana nokuwohloka okubangelwa izici zamakhemikhali, ezibonakalayo nezemvelo.I-RDP ingathuthukisa ukuqina kodaka ngokuthuthukisa ukumelana kwayo namanzi, ukushintsha kwezinga lokushisa kanye nesimo sezulu.Ingase futhi inikeze ukunamathela okuhle phakathi kwezinhlayiya futhi ikhulise izakhiwo zefilimu zodaka, ezingathuthukisa ikhono layo lokumelana nokuguguleka nokuguga.
Ekuphetheni
Ukufingqa, umphumela we-RDP ekwenzeni ngcono udaka ubalulekile.Ingathuthukisa izici zemishini, ikhulise ukubumbana, ithuthukise ukugcinwa kwamanzi, ithuthukise ukusebenza kahle, inciphise ukuqhekeka, futhi ithuthukise ukuqina.Lezi zakhiwo zibalulekile ekuqinisekiseni ikhwalithi yomsebenzi wokwakha kanye nokusebenza kwesikhathi eside kwezakhiwo.Ngakho-ke, i-RDP isetshenziswe kabanzi emkhakheni wokwakha futhi isibe isengezo esibalulekile sokuthuthukisa ukusebenza kodaka.
