I-Dispersible polymer powder (RDP) iyikhemikhali ye-polymer esebenza kahle kakhulu esetshenziswa emkhakheni wokwakha nezimboni. Kuyi-powder material etholwe ngokufafaza ngokumisa i-emulsion polymer, futhi inendawo yokusabalalisa kabusha emanzini ukwenza i-emulsion ezinzile. I-RDP isetshenziswa kakhulu ezintweni zokwakha ezahlukahlukene, ikakhulukazi odakeni olomile, okokunamathelisa amathayela, uhlelo lwangaphandle lokufakwa odongeni (ETICS), kanye nezingubo ezingangeni manzi.
1. Udaka olomile
Enye yezinto ezisetshenziswa kakhulu i-RDP odakeni olomile. Ingathuthukisa ukunamathela, ukuguquguquka kanye nokumelana nokuqhekeka kodaka, kwenze kube lula ukwakha nokuthuthukisa ikhwalithi yokwakha. Ikakhulukazi, indima ye-RDP odakeni olomile ihlanganisa:
Thuthukisa amandla ebhondi: I-RDP ingakha ifilimu enwebekayo ngemva kokuba udaka selaphekile. Le filimu inamandla esibopho esiphezulu, esingathuthukisa ngokuphumelelayo ukunamathela phakathi kodaka kanye ne-substrate futhi kunciphise ingozi yokuqhekeka nokuwa.
Thuthukisa ukuguquguquka: Njengoba ifilimu eyakhiwe i-RDP ivumelana nezimo, ingagcina ubuqotho bodaka futhi ivimbele ukuqhekeka lapho isakhiwo sesakhiwo sinyakaza noma siwohloka kancane.
Thuthukisa ukusebenza komsebenzi wokwakha: I-RDP ingathuthukisa ukuguquguquka nokugcwala kodaka, yenze ukwakha kube lula, ikakhulukazi ukunciphisa amandla okusebenza kanye nokwenza ngcono ukusebenza kahle kokwakhiwa lapho kwakhiwe endaweni enkulu.
2. I-adhesive ye-tile
Ku-adhesive tile, ukungezwa kwe-RDP kungathuthukisa kakhulu ukusebenza kwe-adhesive tile, okuhlanganisa amandla okubopha, izakhiwo zokulwa nokushelela kanye nokulula ukwakha.
Thuthukisa ukunamathela: I-RDP ingakha isendlalelo esiqinile sokubopha ngemva kokuba isinamathiselo sethayili sesomile, siqinisekise ukuthi amathayili angaxhunywa ngokuqinile odongeni noma phansi.
Thuthukisa izakhiwo ezivimbela ukushelela: I-RDP ingavimbela amathayela ukuthi angasheleli ngesikhathi sokwakha futhi iqinisekise ukuthi amathayela angakwazi ukuhlala endaweni enqunywe kusengaphambili ngesikhathi sokugandaywa.
Thuthukisa ukunethezeka kokwakhiwa: Ngemva kokwengeza i-RDP ku-adhesive tile, ukuvumelana kwayo kulula ukulawula, ungqimba olunamathele lufana ngesikhathi sokuhamba, futhi ubunzima bokwakhiwa buyancipha.
3. Uhlelo lwangaphandle lokufakwa kwezindonga (ETICS)
Ukusetshenziswa kwe-RDP ohlelweni lokufakwa odongeni lwangaphandle kubonakala ikakhulukazi ekuthuthukiseni amandla okubopha kanye nokuqina kongqimba lokufakelwa. Isendlalelo se-insulation ngokuvamile sisebenzisa izinto ezingasindi njenge-polystyrene enwetshiwe (EPS) noma i-polystyrene ekhishwe (XPS), edinga ukuxhunywa ngokuqinile odongeni lwangaphandle lwesakhiwo, futhi ukungezwa kwe-RDP kungathuthukisa ngempumelelo ukusebenza kokubopha kwalezi zinto.
Amandla okubopha athuthukisiwe: I-RDP yenza ibhodi lokufakwa ngaphakathi liboshwe ngokuqinile obondeni lwangaphandle, livimbele ungqimba lokufakelwa ukuba ungawi ngenxa yokushintsha kwezinga lokushisa noma amandla angaphandle.
Ukuqina okuthuthukisiwe: I-RDP ingaphinde ithuthukise ukusebenza okunqanda ukuguga kwesendlalelo sokufakelwa futhi yandise impilo yesevisi yesakhiwo, ikakhulukazi ezindaweni zangaphandle ezinokhahlo.
4. Izembatho ezingangeni manzi
Ukusetshenziswa kwe-RDP emigqonyeni engangeni manzi ngokuyinhloko ukuthuthukisa ukungangeni kwamanzi, ukuguquguquka kanye nokumelana nokuqhekeka kokunamathela. Ifilimu ye-polymer eyenziwe yi-RDP ekugqokeni ingavimbela ngokuphumelelayo ukungena kwamanzi, ngaleyo ndlela ithuthukise umphumela wokungangeni kwamanzi.
Ukusebenza okuthuthukisiwe kokuvikela amanzi: Isakhiwo sefilimu eminyene esakhiwe yi-RDP singavimba ngempumelelo ukungena kwamanzi, ikakhulukazi ezindaweni ezinezidingo eziphakeme zokungangeni kwamanzi njengophahla, amagumbi angaphansi nezindlu zangasese.
Ukwenyuka kokuguquguquka: I-RDP emigqonyeni engangeni manzi inganikeza ukuguquguquka okuthile, ivumelane nokuguqulwa okuncane kwe-substrate, futhi ivimbele ukumbozwa ekuqhekekeni.
Thuthukisa ukusebenza kokwakhiwa kwama-coatings: Ukwengezwa kwe-RDP kwenza ukwakhiwa kwezingubo ezingangeni manzi kube lula, ukumbozwa kufana futhi kuncane kakhulu kumabhamuza nokuqhekeka.
5. Ezinye izinhlelo zokusebenza
Ngaphezu kwalezi zindawo zokufaka izicelo ezingenhla, i-RDP ingasetshenziswa nasezitezini ezizilinganisa, izinto zokulungisa udonga, imikhiqizo ye-gypsum kanye nezinsimbi zokushisa ezishisayo. Kulezi zicelo, i-RDP iphinde ibambe iqhaza ekuthuthukiseni ukunamathela kwezinto zokwakha, ukuthuthukisa ukunethezeka kokwakhiwa, nokwandisa ukumelana nokuqhekeka kanye nokuqina.
Njengekhemikhali yokwakha esebenza kahle kakhulu, i-latex powder (RDP) ehlakazekile isetshenziswa kabanzi emikhakheni eminingi ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele. Akugcini nje ukuthuthukisa ukusebenza kwezinto zokwakha, kodwa futhi kuthuthukisa ukunethezeka kokwakhiwa nokuqina kwesakhiwo sokugcina. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, inkambu yokufakwa kwezicelo ye-RDP izoqhubeka nokukhula, futhi kulindeleke ukuthi idlale indima ebaluleke kakhulu kuhlu olubanzi lwezicelo zezimboni nezokwakha esikhathini esizayo.
