I-Redispersible Polymer Powder (RDP) iyisengezo esisebenza ngezindlela eziningi esisetshenziswa kabanzi embonini yezokwakha, ikakhulukazi ekwakhiweni kwezinamatheliso zamathayela.I-RDP iyimpushana ye-polymer eguquliwe eyenziwe ngokufafaza i-emulsion ye-polymer, engase iphinde ihlanganiswe ibe yi-dispersions lapho ithintana namanzi.Lesi sici esiyingqayizivele se-RDP sithuthukisa kakhulu ukusebenza kwezinamathiselo zamathayela ngezindlela ezihlukahlukene, sinikeze izinzuzo ezibalulekile ezenzweni zesimanje zokwakha.
Ukuthuthukisa Ukunamathela
Enye yezinzuzo eziyinhloko ze-RDP kokunamathela kuthayela ukuthuthuka okuphawulekayo kwamandla okunamathela.I-RDP ithuthukisa izici zokubopha zokunamathelisa amathayela, izenze zikwazi ukunamathela ngokuphumelelayo ezinhlobonhlobo zama-substrates, okuhlanganisa ukhonkolo, ukhonkolo, namathayili akhona.Lokhu kubaluleke kakhulu ekuqinisekiseni ukuthi amathayela ahlala esendaweni evikelekile ngokuhamba kwesikhathi, ngisho nangaphansi kwengcindezi.
Izinhlayiya ze-polymer ku-RDP ziyahlangana zenze ifilimu ye-polymer eqhubekayo lapho okunamathelayo kusetha futhi komile.Le filimu ingena nge-matrix kasimende ye-adhesive, idala isibopho esiqinile semishini.Ukwengeza, i-polymer ilungisa ukuxhumana phakathi kwe-adhesive ne-substrate, ikhuthaze ukunamathela okungcono ngokusebenzisa izakhiwo zokumanzisa ezithuthukisiwe kanye nokuxhumana kwendawo.Lokhu kuholela emandleni okugunda athuthukisiwe kanye nokumelana okukhulu namandla aqinile, okuqinisekisa ukuthi amathayili awasuki kalula.
Ukwandisa Ukuguquguquka Nokuguquguquka Kwamandla
I-RDP inegalelo elikhulu ekuguquguqukeni nasekushintsheni umthamo wokunamathela kuthayela.Izinamathiselo ezisekelwe kusimende zendabuko zingaba brittle futhi zithambekele ekuqhekekeni ngaphansi kwengcindezi eshisayo neyomshini.Ukufakwa kwe-RDP kushintsha izici zokunamathisela ze-adhesive, kunikeza ukuguquguquka nokunwebeka.Lokhu kunenzuzo ikakhulukazi ezinhlelweni zokusebenza lapho amathayela engaphansi komnyakazo noma ukudlidliza, njengendawo enabantu abaningi noma kuma-substrates anwebekayo futhi ancipha ngenxa yokuhluka kwezinga lokushisa.
Ifilimu ye-polymer eyakhiwe yi-RDP isebenza njengebhuloho phakathi kwe-matrix kasimende eqinile kanye nethayela eliguquguqukayo, okuvumela okunamathelayo ukuthi kumunce futhi kuqede ingcindezi.Lokhu kunciphisa ubungozi bokuqhekeka nokuqhekeka, ngaleyo ndlela kuthuthukisa ukusebenza kwesikhathi eside nokuqina kwendawo enamathayela.
Ukuthuthukisa Ukumelana Namanzi
Ukumelana namanzi kuyisici esibalulekile sokunamathela kuthayela, ikakhulukazi ezindaweni ezichayeke kumswakama, njengezindlu zangasese, amakhishi, namachibi okubhukuda.I-RDP ithuthukisa ukumelana kwamanzi kwezinamathelisi zamathayili ngokunciphisa ukungenwa kwazo.Ifilimu ye-polymer eqhubekayo eyenziwe yi-RDP isebenza njengesithiyo, ivimbela amanzi ukuthi angangeni ungqimba olunamathelayo futhi afinyelele ku-substrate.
Lokhu kumelana kwamanzi okuthuthukisiwe kusiza ekugcineni ubuqotho besibopho sokunamathela ngokuhamba kwesikhathi, ukuvimbela izinkinga ezifana ne-efflorescence, ukukhula kwesikhunta, nokuwohloka kwe-substrate.Ngaphezu kwalokho, izinto ezinamathelayo eziguqulwe i-RDP zibonisa ukusebenza okungcono emijikelezweni yokuncibilika kweqhwa, okubalulekile ekufakweni kwangaphandle lapho izinto ezinamathelayo zichayeka ezimweni zezulu ezihlukahlukayo.
Ukuthuthukisa Ukusebenza Nesikhathi Esivulekile
Ukusebenza nesikhathi sokuvula yizici ezibalulekile kubafaki bamathayela.Ukusebenza kubhekisela endleleni okunamathelayo okulula ngayo ukuxuba, ukusabalalisa, nokulungisa ngesikhathi sokufaka isicelo, kuyilapho isikhathi esivulekile siyinkathi lapho okunamathelayo kuhlala kuqinile futhi kusebenza ngemva kokusabalalisa ku-substrate.
I-RDP ithuthukisa ukusebenza kwezinamatheliso zamathayili ngokunikeza ukufana okubushelelezi, okukhilimu okulula ukukuphonseka kalula.Lokhu kusiza uhlelo lokusebenza olusheshayo futhi olusebenza kahle, lunciphisa isikhathi somsebenzi nokuzikhandla.Ukwengeza, ukuba khona kwe-RDP kwandisa isikhathi esivulekile sokunamathela, kunikeza abafaki ukuguquguquka okwengeziwe nesikhathi sokubeka amathayili ngokunembile ngaphandle kokujaha.Lokhu kunenzuzo ikakhulukazi ekufakweni kwesilinganiso esikhulu lapho kudingeka ukuqondanisa okunembile nokulungiswa kwamathayili.
Ukuthuthukisa Ukuqina
Ukuqina kwesikhathi eside kokufakwa kwamathayela kuwukukhathazeka okubalulekile ekwakhiweni.I-RDP ithuthukisa ukuqina kwezinamatheliso zamathayela ngokwenza ngcono izakhiwo zazo zemishini kanye nokumelana nezinto zemvelo.Izici zokuguquguquka nokunamathela ezinikezwa i-RDP zisiza ekugcineni ubuqotho bebhondi yokunamathela ngokuhamba kwesikhathi, ngisho nangaphansi kwemithwalo eguquguqukayo kanye nokuguquguquka kwezinga lokushisa.
Ngaphezu kwalokho, i-RDP ithuthukisa ukumelana kwe-adhesive ekuhlaselweni kwamakhemikhali avela kuma-ejenti okuhlanza nezinye izinto, iqinisekisa ukuthi indawo enamathayela ihlala injalo futhi ijabulisa ngobuhle.Ifilimu ye-polymer isiza futhi ekuvimbeleni ukwakheka kwama-microcracks, angasakaza futhi aholele ekuhlulekeni kwesibopho sokunamathela.
Izifundo Nezicelo
Izibonelo ezimbalwa zezifundo kanye nezicelo zibonisa izinzuzo ezingokoqobo ze-RDP ekunamathiseleni amathayela.Isibonelo, ezakhiweni eziphakeme kakhulu lapho ukufakwa kwamathayela kungaphansi kokunyakaza okuphawulekayo nokudlidliza, okunamathelayo okulungiswe i-RDP kubonise ukusebenza okuphezulu ekugcineni ubuqotho bebhondi.Ngokufanayo, ekufakweni kwedamu lokubhukuda lapho ukumelana namanzi kubaluleke kakhulu, izinto zokunamathisela ezithuthukisiwe ze-RDP zibonakale zisebenza ngempumelelo ekuvimbeleni ukungena kwamanzi kanye nezinkinga ezihambisanayo.
Emaphrojekthini okulungisa lapho kufakwa khona amathayela phezu kwama-substrates akhona, izinto zokunamathisela eziguqulwe i-RDP zinikeza ukunamathela okuthuthukisiwe nokuguquguquka, okuhlanganisa ukunyakaza okuncane nokungapheleli kwendawo engaphansi.Lokhu kuguquguquka kwenza i-RDP ibe yingxenye ebalulekile ezinhlobonhlobo zezicelo zamathayili, kusukela endaweni yokuhlala kuya kweyokuhweba nezimboni.
I-Redispersible Polymer Powder (RDP) idlala indima ebalulekile ekuthuthukiseni ukusebenza kwezinamathiselo zamathayela.Ikhono layo lokuthuthukisa ukunamathela, ukuguquguquka, ukumelana namanzi, ukusebenza kahle, nokuqina kuyenza ibe isithasiselo esibalulekile emisebenzini yesimanje yokwakha.Ngokwenza ifilimu ye-polymer eqhubekayo ngaphakathi kwe-adhesive matrix, i-RDP inikeza izinzuzo ezibalulekile empumelelweni yesikhathi eside yokufakwa kwamathayili.Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukubaluleka kwe-RDP ekuqinisekiseni ukwakheka kokunamathela kwamathayela okuseqophelweni eliphezulu, okuhlala isikhathi eside, nokuthembekile kungase kukhule, kuqhubekisele phambili ukusungulwa kanye nezinqubo zokwakha ezithuthukisiwe.
