I-redispersible latex powder (RDP) iyisengezo sezinto zokwakha ezibalulekile ezisetshenziswa kabanzi kuma-adhesive athayela. Akugcini nje ukuthuthukisa izici ezihlukahlukene zokunamathisela amathayili, kodwa futhi ixazulula ezinye zeziphambeko zezinto zokubopha zendabuko.
1. Thuthukisa ukunamathela
Omunye wemisebenzi eyinhloko ye-latex powder ehlakazeka kabusha ukuthuthukisa amandla okubopha ama-adhesives we-tile. Izinamatheliso ezisekelwe kusimende zendabuko zakha umkhiqizo oqinile ngemva kokufakwa kwamanzi, okunikeza amandla athile okubopha. Nokho, ukuqina kwale mikhiqizo eqinile kunciphisa ukunamathela. I-latex powder ehlakazeka kabusha iphinde ihlakazwe emanzini ukuze yakhe izinhlayiya ze-latex, ezigcwalisa izimbotshana kanye nokuqhekeka kwezinto ezisekelwe kusimende futhi zenze ifilimu enamathelayo eqhubekayo. Le filimu ayigcini nje ukwandisa indawo yokuxhumana, kodwa futhi inikeza i-adhesive izinga elithile lokuguquguquka, ngaleyo ndlela ithuthukise kakhulu amandla okubopha. Lokhu kuthuthukiswa kubaluleke kakhulu ekufakweni kwamathayela e-ceramic lapho amandla ebhondi ephezulu edingeka khona.
2. Thuthukisa ukuguquguquka nokumelana nokuqhekeka
Impushana ye-latex ehlakazeka kabusha inganikeza okunamathelayo kwamathayili ukuguquguquka okungcono nokumelana nokuqhekeka. Kuma-adhesives, ukuba khona kwe-RDP kwenza ungqimba omisiwe olunamathelayo lube nokunwebeka okuthile, ukuze lukwazi ukumelana nokukhubazeka okuncane okubangelwa ukushintsha kwezinga lokushisa, ukuguqulwa kwe-substrate noma ukucindezeleka kwangaphandle. Lokhu kusebenza okuthuthukisiwe kunciphisa ubungozi bokuqhekeka noma ukuqhekeka, ikakhulukazi ekufakweni kwamathayela amakhulu noma lapho amathayela abekwe ezindaweni ezinengcindezi ephezulu.
3. Thuthukisa ukumelana namanzi
Ukumelana namanzi kubalulekile ekusebenzeni isikhathi eside kwe-adhesive tile. I-latex powder ehlakazeka kabusha ivimba ngempumelelo ukungena kwamanzi ngokwakha inethiwekhi ye-polymer eminyene. Lokhu akugcini nje ukuthuthukisa ukumelana kwamanzi kwe-adhesive, kodwa futhi kuthuthukisa amandla ayo okumelana nemijikelezo yokuqhwala, okuvumela i-adhesive tile ukugcina ukunamathela okuhle nokuzinza kwesakhiwo ezindaweni ezinomswakama.
4. Thuthukisa ukwakhiwa kanye namahora okuvula
I-latex powder ehlakazeka kabusha ingathuthukisa ukusebenza kokwakhiwa kwezinamathelisi zamathayili. Izinto ezinamathelayo ezingezwe nge-RDP zinokuthambisa nokusebenza okungcono, okwenza ukwakhiwa kube lula. Ngesikhathi esifanayo, iphinde yandise isikhathi esivulekile sokunamathisela (okungukuthi, isikhathi esisebenzayo lapho i-adhesive inganamathela ku-tile ngemva kokufaka isicelo). Lokhu kunikeza izisebenzi zokwakha isikhathi esengeziwe sokusebenza, okusiza ukuthuthukisa ukusebenza kahle nekhwalithi yokwakha.
5. Thuthukisa ukumelana nesimo sezulu kanye nokuqina
Ukumelana nesimo sezulu nokuqina yizici ezibalulekile ezithonya ukusebenza kwesikhathi eside kwezinamathelisi zamathayili. Izinhlayiya ze-polymer ku-RDP cross-link ngesikhathi senqubo yokuphulukisa ye-adhesive, zakha inethiwekhi ye-polymer ezinzile kakhulu. Le nethiwekhi ingamelana ngokuphumelelayo nethonya lezici zemvelo njengemisebe ye-ultraviolet, ukuguga okushisayo, ukuguguleka kwe-asidi kanye ne-alkali, ngaleyo ndlela ithuthukise ukumelana nesimo sezulu nokuqina kwe-adhesive ye-tile futhi yandise impilo yayo yesevisi.
6. Yehlisa ukumuncwa kwamanzi futhi uthuthukise ukumelana nesikhutha
I-latex powder ehlakazeka kabusha inganciphisa izinga lokumuncwa kwamanzi kwezinamathelisi zamathayili, ngaleyo ndlela yehlise ukwehluleka kongqimba olubophezelayo olubangelwa ukunwetshwa kwe-hygroscopic. Ngaphezu kwalokho, ingxenye ye-polymer ye-hydrophobic ye-RDP ingavimbela ukukhula kwesikhunta namanye ama-microorganisms, ngaleyo ndlela ithuthukise izakhiwo ezimelana nesikhunta ze-adhesives tile. Lokhu kubaluleke kakhulu ezindaweni ezinomswakama noma ezinomswakama ophezulu, njengezindlu zangasese namakhishi.
7. Zivumelanise nezinhlobonhlobo zama-substrates
Impushana ye-latex ehlakazeka kabusha inika ingcina yethayili ikwazi ukuzivumelanisa nezimo ezinhle ze-multi-substrate. Kungakhathaliseki ukuthi amathayela abushelelezi a-vitrified, amathayili e-ceramic amunca kakhulu amanzi, noma amanye ama-substrates afana nebhodi likasimende, ibhodi le-gypsum, njll., izinto ezinamathelayo ezengezwe nge-RDP zinganikeza izakhiwo ezinhle kakhulu zokubopha. Lokhu kuvumela ukusetshenziswa okubanzi phakathi kwezinhlobo ezahlukene zamathayili nama-substrates.
8. Ukuvikelwa kwemvelo
Izinto zokwakha zanamuhla ziya ngokuya zigcizelela ukuvikelwa kwemvelo. Impushana ye-latex ehlakazeka kabusha imvamisa yenziwa ngezinto ezihambisana nemvelo njenge-polyvinyl alcohol ne-acrylate. Ayiqukethe ama-solvents ayingozi nezinsimbi ezinzima futhi ihlangabezana nezidingo zezinto zokwakha eziluhlaza. Ngaphezu kwalokho, i-RDP ayikhiphi ama-volatile organic compounds (VOC) ngesikhathi sokwakha, okunciphisa ukulimala kwabasebenzi bokwakha kanye nemvelo.
Ukusetshenziswa kwe-latex powder e-redispersible kuma-adhesive tile e-ceramic kuthuthukisa kakhulu ukusebenza okuphelele kokunamathela, okuhlanganisa ukunamathela, ukuguquguquka, ukumelana kwamanzi, ukwakhiwa, ukumelana nesimo sezulu, ukumelana nesikhutha nokuvikelwa kwemvelo. Lokhu kuthuthukiswa akuthuthukisi nje kuphela ukusebenza kahle kwesakhiwo nokusebenza kahle, kodwa futhi kwandise impilo yesevisi ye-adhesives yamathayili, okubenza bakwazi ukuzivumelanisa nobubanzi obubanzi bezimo zohlelo lokusebenza. Ngakho-ke, i-RDP ithatha isikhundla esibalulekile ekwakhiweni kwesimanje kokunamathela kuthayela we-ceramic, ehlinzeka ngosekelo oluqinile lokuthuthukisa ikhwalithi yamaphrojekthi wokwakha.
