Impuphu yePolymer Ephinde Ihlakazeke (RDP), njengesithako esibalulekile se-polymer, sisetshenziswe kabanzi eminyakeni yamuva nje ku-dry-mix mortar, i-tile adhesive, i-putty powder, i-plastering mortar, kanye ne-grout. Ukusetshenziswa kwayo ku-tile grout kubaluleke kakhulu ekuthuthukiseni amandla e-bond, ukuguquguquka, ukumelana nokuqhekeka, kanye nokumelana namanzi.
1. Indlela Yokusebenza Ye-RDP
I-RDP iyimpuphu ephinde ihlakazeke eyenziwe nge-polymer emulsion ngenqubo yokomisa ngokufutha, enesici sokuphinda i-emulsification lapho ihlangana namanzi. Lapho i-RDP ingezwa ku-grout, njengoba amanzi ehwamuka ngesikhathi sokwakhiwa, izinhlayiya ze-RDP ziyahlakazeka kabusha ukuze zakhe ifilimu ye-polymer eqhubekayo. Le filimu ye-polymer ihlangana nemikhiqizo yokudonsa uketshezi lwesimende, yakha "uhlelo oluhlanganisiwe lwe-inorganic-organic," oluthuthukisa kakhulu izakhiwo zemishini zezinto kanye nezici zokubopha phakathi kobuso.
Ngesikhathi senqubo yokulungisa i-grout, ifilimu ye-RDP polymer ingamboza izinhlayiya zokugcwalisa, ithuthukise ukunamathelana kwe-interfacial futhi inciphise ukugoba kohlelo olusekelwe kusimende. Ngaphezu kwalokho, izingxenye eziguquguqukayo kuma-molecule e-RDP zinikeza i-grout izinga elithile lokuguguleka kanye nokumelana nokuguquguquka, okuvimbela ngempumelelo imifantu ebangelwa ukushintsha kwezinga lokushisa noma ukuguquguquka kwe-substrate.
2. Ukuthuthukiswa kwe-RDP kokusebenza kwe-Tile Grout
2.1. Amandla Esibopho Athuthukisiwe
Isidingo esiyinhloko se-grout yethayela ukunamathela kahle emaphethelweni ethayela kanye ne-substrate. I-RDP yakha ifilimu ye-polymer yemvelo, okwenza ukuxhumana phakathi kwe-grout esekelwe kusimende kanye nobuso bethayela kuhlanganiswe ngokuqinile. Ngesikhathi esifanayo, i-polymer residue ngemva kokusabela kwe-hydration ye-RDP ithuthukisa ubuningi besendlalelo se-interface, ngaleyo ndlela ithuthukisa kakhulu amandla e-grout kanye nokuqina kwayo.
2.2. Ukuguquguquka Okuthuthukisiwe Nokumelana Nokuqhekeka
Ama-grout endabuko asekelwe kusimende avame ukuba nemifantu emincane lapho omisa ukuncipha noma ukushintsha kwezinga lokushisa, okuthinta ubuhle kanye nokusebenza kokuvimbela amanzi. Ukufakwa kwezingxenye ze-polymer ku-RDP kuthuthukisa ukuguquguquka kwezinto zokwakha, okuvumela ungqimba lwe-grout ukuthi lukwazi ukumelana nokucindezeleka okuthile kanye nokuguquguquka ngaphandle kokuqhekeka, ngaleyo ndlela lwandise impilo yalo yokusebenza.
2.3. Ukuthuthukiswa Kokungangenwa Kwamanzi kanye Nokungangeni Kwamanzi
Ifilimu ye-polymer eqhubekayo eyakhiwe yi-RDP ine-permeability ephansi, ivimbela ngempumelelo ukungena kwamanzi futhi inciphise ukumuncwa kwamanzi. Lesi sici sibaluleke kakhulu ezindaweni ezimanzi njengekhishi nezindlu zangasese, ivimbela ngempumelelo umswakama ukuthi ungene ngemuva kwamathayili noma i-substrate eceleni kwezikhala, inciphisa ingozi yokukhunta kanye nokugoba.
2.4. Ukumelana Okuthuthukisiwe Kokuguguleka Nokumelana Namabala
I-RDP esezingeni eliphezulu ithuthukisa ubuningi bomphezulu we-grout, okwenza ibe bushelelezi, imelane nokuguguleka kakhudlwana, futhi inciphise ukunamathela kokungcola. I-grout eguquliwe yi-RDP ayithambekeli kakhulu ekuqongeleleni uthuli noma ekushintsheni umbala ngesikhathi sokuhlanza nsuku zonke, igcina ukubukeka kwayo okuhle isikhathi eside.
2.5. Ukusebenza Okuthuthukisiwe Kwesicelo
I-RDP ithuthukisa kakhulu ukugeleza kokufakwa kanye nokugcinwa kwamanzi kwe-grout, yenza ukusetshenziswa kube lula, kube lula ukugcwalisa izikhala, futhi kuncishiswe izikhala kanye namabhamuza omoya. Ngesikhathi esifanayo, umphumela wayo wokugcina amanzi wehlisa izinga lokumanzisa kwesimende, unikeze abasebenzi isikhathi esengeziwe sokufaka futhi uthuthukise ikhwalithi nokusebenza kahle kokufakwa.
3. Ukusebenza Kohlelo Lokusebenza Lwe-RDP Ezinhlotsheni Ezihlukene Ze-Grout
3.1. I-Grout Esekelwe Kusimende
Ukwengeza i-RDP ku-grout evamile esekelwe kusimende kuthuthukisa kakhulu ukunamathela kanye nokumelana nokuqhekeka, okwenza ifaneleke kakhulu ekuhlanganiseni amathayili odonga kanye naphansi angaphakathi nangaphandle.
3.2. I-Epoxy noma i-Grout Esebenza Kakhulu
Kuma-grout asezingeni eliphezulu adinga ukumelana nokuguguleka okuphezulu kanye nokungangeni kwamanzi, i-RDP, njenge-modifier, isebenza ngokubambisana namanye ama-resin ukuze ithuthukise ukuguquguquka nokunamathela.
3.3. I-Grout Enemibala
Izakhiwo zokwakha ifilimu ye-RDP zisiza ukuqinisekisa ukusatshalaliswa kombala okufanayo, zithuthukise ukuqina kombala, zivimbele umehluko wombala kanye nokugqama, futhi zenze ama-grout anemibala ahlobise kakhulu.
4. Inani Lokusetshenziswa kanye Nezindlela Zokuthuthukiswa kwe-RDP
Ngamafuphi, inani lokusetshenziswa kwe-RDP ku-grout yethayela libonakala kakhulu kulezi zici ezilandelayo:
Ukuthuthukiswa Kokusebenza Komkhiqizo: Ngokuthuthukisa ukunamathela, ukuvimbela amanzi, kanye nokuguquguquka, i-grout igcina ukusebenza okuhle kakhulu ezindaweni ezahlukene.
Impilo Yesevisi Eyengeziwe: Ukumelana nokuqhekeka okuthuthukisiwe kanye nokumelana nokuguguleka, kunciphisa izindleko zokulungisa kamuva.
Ukuthuthukisa ulwazi lokwakha kanye nekhwalithi yomkhiqizo oqediwe: Kuthuthukisa ukusebenza kahle kanye nokugcinwa kwamanzi, kunciphisa amaphutha okwakha.
Ukuhambisana nesiqondiso sokuthuthukiswa kwezinto zokwakha eziluhlaza: I-RDP iyinto engenazo izinyibilikisi, engena-VOC eningi, ehlangabezana nezidingo zokuvikelwa kwemvelo futhi enikela ekwakhiweni kwezinhlelo zokwakha eziluhlaza.
Njengoba imboni yokuhlobisa izakhiwo ithuthuka iye ekusebenzeni okuphezulu, ekuvikelweni kwemvelo, kanye nasekubukekeni kahle, indima ye-RDP ku-grout yethayela izoba yinto ebaluleke kakhulu. Ucwaningo lwesikhathi esizayo kanye nentuthuko luzogxila ekuthuthukiseni izinhlelo ze-polymer ezinokumelana nesimo sezulu okuphezulu, ukumuncwa kwamanzi okuphansi, kanye nokunamathela okuqinile ukuhlangabezana nezidingo zohlelo lokusebenza ngaphansi kwezimo zezulu ezahlukene kanye nezimo zokwakha.
Njengezinto zokuguqula eziyinhloko ku-grout yethayela,I-RDPingathuthukisa kakhulu izakhiwo zayo zomshini, ukumelana nokuqhekeka, ukuvimbela amanzi, kanye nokusebenza kahle, okwenza kube yisithasiselo esibalulekile sokufeza imiphumela yokuhlobisa isakhiwo esezingeni eliphezulu. Ukusetshenziswa kwayo kabanzi akugcini nje ngokuthuthukisa ukusebenza kwe-grout kodwa futhi kunikeza ukwesekwa okuqinile ekuthuthukisweni kwezinto zokwakha eziluhlaza nezonga amandla.
