I-Redisperible Powmer Powder (RDP) iyimpuphu esekelwe e-polymer etholwe ngokufafaza isifutho sokuhlakazeka kwe-polymer. Le mpuphu ingahle iphindiswe emanzini ukuze kwakhiwe i-latex enezakhiwo ezifanayo ekusakazweni kokuqala kwe-polymer. I-RDP ivame ukusetshenziswa embonini yezokwakha njengesengezo esemqoka ezintweni zokwakha. Nakhu ukubuka konke kwe-RDP kumongo wezinto zokwakha:
Izici ezibalulekile ze-RDP ezintweni zokwakha:
1. Ukuthuthukisa ukuguquguquka nokunamathelisa:
- I-RDP ithuthukisa ukuguquguquka nokunamathelisa kwezinto zokwakha ezifana nodaka, izinamathiseli zethayela, kanye nama-render. Lokhu kubaluleke kakhulu kwizicelo zokwakha lapho ukuqina namandla kubalulekile.
2. Ukugcinwa kwamanzi:
- I-RDP ithuthukisa amandla okugcina amanzi kwezinto zokwakha, iqinisekisa i-hydrate efanele yezakhi ze-cemeenment. Lokhu kunomthelela ekusebenzikeni okungcono kanye nesikhathi esengeziwe sokuvulwa kwezicelo ezifana nama-tile adhesives.
3. Ukubumbana okwandayo namandla:
- Ku-dolondane kanye nodondolo, i-RDP isebenza njenge-binder, ngcono ukubumbana kwezinto ezibonakalayo kanye nokuthuthukisa amandla. Lokhu kubalulekile ukuthola izicelo lapho ubuqotho bezinhlekelele lubalulekile.
4. Yehlise ukushwabana:
- Ukufakwa kwe-RDP kwezinto zokwakha kusiza ukunciphisa i-shrinkage ngesikhathi senqubo yomiswa. Lokhu kubalulekile ukuvimbela ukuqhekeka kanye nokuqinisekisa ukuqina kwezakhiwo zesikhathi eside.
5. Ukuphikiswa okuthuthukile komthelela:
- I-RDP inikela ekumelaneni nomthelela wokumelana kwama-coatings kanye nama-render, ukuhlinzeka ngongqimba oluvikelayo olungamelana namandla angaphandle.
6. Ukusebenza okuthuthukile:
- Ukusetshenziswa kwe-RDP kuthuthukisa ukusebenziseka kwezinto zokwakha, okwenza kube lula ukuxuba, ukufaka isicelo kanye nesimo. Lokhu kunenzuzo ngesikhathi sokwakha.
Izicelo ezintweni zokwakha:
1. Amathayela anamathela nama-grouts:
- I-RDP isetshenziswa kakhulu kuma-tile anamathela kanye nama-grouts ukuthuthukisa ukunamathela, ukuguquguquka nokumelana kwamanzi. Kuyasiza ekuqinisekiseni ukuthi amathayili ahlala ephephile endaweni.
2. Ukufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIF):
- I-RDP isetshenziswa kuma-EIFS ukuthuthukisa ukunamathela nokuguquguquka kohlelo. Iphinde ifake isandla ekunqumelweni kohlelo kanye nokumelana nezici zezemvelo.
3. UDortars noDenders:
- Ku-Donswars kanye ne-Render, i-RDP isebenza njengesengezo esibalulekile sokwenza ngcono ukuhlangana, amandla nokusebenza. Kuyasiza ekuvikeleni imifantu kanye nokwenza ngcono ukusebenza okuphelele.
I-4. Amakhompiyutha wokuzimela:
- I-RDP isetshenziswa kumakhompiyutha wokuzenzisa ukuze athuthukise izindawo zokugeleza kanye nokunamathelisa. Lokhu kubalulekile ekufezeni indawo ebushelelezi neleveli.
5. Imikhiqizo esekwe ku-gypsum:
- I-RDP ingafakwa kwimikhiqizo esekwe ku-gypsum ukuthuthukisa ukunamathela kwayo, ukumelana kwamanzi, kanye nokusebenza okuphelele.
Ukucatshangelwa kokukhethwa:
1. Uhlobo lwe-polymer:
- I-RDPS ehlukene ingahle isuselwe ezinhlotsheni ezahlukahlukene ze-polymer, njenge-vinyl acetate ethylene (VAE) noma i-styrere buthadiene (sb). Ukukhetha kuncike kwizidingo ezithile zohlelo lokusebenza.
2 isilinganiso isilinganiso sethafa:
- Umthamo we-RDP ekwakhekeni kuncike ezintweni ezinjengeluhlobo lwezinto zokwakha, izakhiwo ezifiselekayo, nezidingo zohlelo lokusebenza.
3. Ukuvumelana:
- Ukuqinisekisa ukuhambisana nezinye izithako ekwakhiweni kubalulekile ekufezekiseni ukusebenza okufunayo kwezinto zokwakha.
4. Izindinganiso zekhwalithi:
- I-RDP kufanele ihlangabezane namazinga afanelekile kanye nokucaciswa kokuqinisekisa ukusebenza okungaguquki nokuthembekile kwizicelo zokwakha.
Kubalulekile ukuqaphela ukuthi imihlahlandlela ethile yokwakheka kanye nohlelo lokusebenza ingahluka phakathi kwabakhiqizi nemikhiqizo. Ngakho-ke, ukubonisana nabaphakeli kanye nokulandela izincomo zabo kubalulekile ukuze kube nemiphumela efanele.
