I-Redispersible Polymer Powder (i-RDP) yinto eyongeziweyo eyongeziweyo esetyenziswa ngokubanzi kwishishini lokwakha, ngokukodwa ekuqulunqweni kwe-adhesive tile. I-RDP yipolymer powder eguqulweyo eyenziwe ngokutshiza-yomisa i-emulsion ye-polymer, enokuthi iphinde iphinde iphinde ihlaziywe xa idibene namanzi. Olu phawu lukhethekileyo lwe-RDP luphucula kakhulu ukusebenza kokuncamatheliswa kweethayile ngeendlela ezahlukeneyo, lubonelela ngeenzuzo ezibalulekileyo kwimisebenzi yolwakhiwo lwangoku.
Ukuphucula ukunamathela
Enye yeenzuzo eziphambili ze-RDP kwii-adhesives ze-tile kukuphucula okubalulekileyo kumandla okunamathela. I-RDP iphucula iipropati zokudityaniswa kwee-adhesives ze-tile, ezibenza bakwazi ukubambelela ngokufanelekileyo kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa ikhonkrithi, i-plaster, kunye neethayile ezikhoyo. Oku kubaluleke ngakumbi ekuqinisekiseni ukuba iithayile zihlala zikhuselekile ekuhambeni kwexesha, naphantsi koxinzelelo.
Iinqununu ze-polymer kwi-RDP zidibanisa ukwenza ifilimu ye-polymer eqhubekayo xa i-adhesive iseti kwaye yomile. Le filimu idibanisa kunye ne-matrix ye-samente ye-adhesive, idala ibhondi eyomeleleyo yomatshini. Ukongeza, i-polymer iguqula i-interface phakathi kwe-adhesive kunye ne-substrate, ikhuthaza ukunamathela okungcono ngokuphuculwa kweempawu zokumanzisa kunye noqhagamshelwano lomphezulu. Oku kukhokelela ukomelezwa kokucheba kunye nokuxhathisa okukhulu kumandla okuqina, nokuqinisekisa ukuba iithayile azichithi lula.
Ukwandiswa kokuGuquguquka kunye noKwakho koGuquko
I-RDP inegalelo elikhulu ekuguquguqukeni kunye nokuguqulwa kwamandla okunamathela kwi-tile. I-adhesives esekelwe kwi-samente yendabuko ingaba yi-brittle kwaye ithande ukuqhekeka phantsi koxinzelelo lwe-thermal kunye noomatshini. Ukudityaniswa kwe-RDP kulungisa iimpawu zokuncamathelisa komatshini, ukunika ukuguquguquka kunye nokunwebeka. Oku kunenzuzo ngakumbi kwizicelo apho iithayile ziphantsi kokunyakaza okanye ukungcangcazela, njengakwindawo ezinabantu abaninzi betrafikhi okanye kwii-substrates ezandayo kunye nezivumelwano ngenxa yokwahluka kwamaqondo obushushu.
Ifilimu ye-polymer eyenziwe yi-RDP isebenza njengebhuloho phakathi kwe-matrix eqinile ye-cementitious kunye ne-tile eguquguqukayo, evumela ukuba i-adhesive ithathe kwaye ikhuphe uxinzelelo. Oku kunciphisa umngcipheko wokuqhekeka kunye ne-delamination, ngaloo ndlela kuphuculwe ukusebenza kwexesha elide kunye nokuqina kwendawo enethayile.
Ukuphucula ukuxhathisa kwamanzi
Ukumelana namanzi luphawu olubalulekileyo lokuncamathelisa iithayile, ngakumbi kwiindawo ezivezwe kukufuma, njengamagumbi okuhlambela, amakhitshi, namachibi okuqubha. I-RDP iphucula ukuxhathisa kwamanzi okunamathela kwiithayile ngokunciphisa ukunyanzeliswa kwazo. Ifilimu ye-polymer eqhubekayo eyenziwa yi-RDP isebenza njengomqobo, ukuthintela amanzi ukuba angene kwi-adhesive layer kwaye afikelele kwi-substrate.
Olu phuculo lokumelana namanzi lunceda ekugcineni ingqibelelo ye-adhesive bond ekuhambeni kwexesha, ukuthintela imiba efana ne-efflorescence, ukukhula kwesikhunta, kunye nokuthotywa kwe-substrate. Ngaphezu koko, i-RDP-modified adhesives ibonisa ukusebenza okungcono kwimijikelo yokunyibilika komkhenkce, eyimfuneko kwizicelo zangaphandle apho izinto zokuncamathelisa zibonakaliswe kwiimeko zemozulu ezahlukeneyo.
Ukuphucula ukusebenza kunye nexesha elivulekileyo
Ukusebenza kunye nexesha elivulekileyo zizinto ezibalulekileyo kubafaki beetayile. Ukusebenza kubhekisela kwindlela ekulula ngayo i-adhesive ukuxuba, ukusabalalisa, kunye nokulungelelanisa ngexesha lesicelo, ngelixa ixesha elivulekileyo lixesha apho i-adhesive ihlala i-tacky kwaye isebenze emva kokusasazeka kwi-substrate.
I-RDP iphucula ukusebenza kwezinto zokuncamathelisa iithayile ngokubonelela ngokugudileyo, ukungaguquguquki kwekhrimu ekulula ukuyibhuqa. Oku kuququzelela usetyenziso olukhawulezayo nolusebenzayo, ukunciphisa ixesha labasebenzi kunye nomgudu. Ukongeza, ubukho be-RDP bandisa ixesha elivulekileyo lokuncamathelisa, ukunika abafakeli ukuguquguquka ngakumbi kunye nexesha lokubeka iithayile ngokuchanekileyo ngaphandle kokungxama. Oku kunenzuzo ngakumbi kufakelo olukhulu apho kufuneka ulungelelwaniso oluchanekileyo kunye nohlengahlengiso lweethayile.
Ukuphucula Ukuqina
Ukuqina kwexesha elide lofakelo lweethayile kuyinkxalabo ebalulekileyo kulwakhiwo. I-RDP iphucula ukuqina kwezinto zokuncamathelisa iithayile ngokuphucula iimpawu zabo zoomatshini kunye nokuchasana nezinto ezisingqongileyo. Ukuguquguquka kunye neempawu zokubambelela ezinikezelwa yi-RDP zinceda ekugcineni ingqibelelo yebhondi yokunamathela ngokuhamba kwexesha, naphantsi kwemithwalo eguquguqukayo kunye nokuguquguquka kweqondo lokushisa.
Ngaphaya koko, i-RDP yongeza ukuxhathisa kokuncamathelisa kuhlaselo lweekhemikhali ezisuka kwiiarhente zokucoca kunye nezinye izinto, iqinisekisa ukuba umphezulu ofakwe ithayile uhlala ucocekile kwaye uthandeka ngobuhle. Ifilimu ye-polymer iphinda incede ekuthinteleni ukubunjwa kwe-microcracks, enokuthi isasaze kwaye iholele ekungaphumeleli kwe-adhesive bond.
Izifundo zeMyelo kunye nezicelo
Izifundo ezininzi kunye nezicelo zibonisa iingenelo ezisebenzayo zeRDP kwizinto zokuncamathelisa iithayile. Ngokomzekelo, kwizakhiwo eziphakamileyo apho ukufakwa kwee-tile kuxhomekeke kwintshukumo ebalulekileyo kunye nokunyakaza, i-RDP-modified adhesives ibonise ukusebenza okuphezulu ekugcineni ukunyaniseka kwebhondi. Ngokufanayo, kufakelo lwamadama okuqubha apho ukunganyangeki kwamanzi kubaluleke kakhulu, i-RDP-i-adhesives ephuculweyo ibonise ukuba iyasebenza ekuthinteleni ukungena kwamanzi kunye nemiba ehambelana nayo.
Kwiiprojekthi zokulungiswa apho iithayile zifakwe phezu kwe-substrates ekhoyo, i-RDP-modified adhesives inikezela ukubambelela okuphuculweyo kunye nokuguquguquka, ukulungiselela ukunyakaza okuncinci kunye nokungafezeki kwendawo engaphantsi. Oku kuguquguquka kwenza i-RDP ibe licandelo elixabisekileyo kuluhlu olubanzi lwezicelo zokufaka iithayile, ukusuka kwindawo yokuhlala ukuya kwiindawo zorhwebo nezoshishino.
I-Redispersible Polymer Powder (RDP) idlala indima ebalulekileyo ekwandiseni ukusebenza kokuncamatheliswa kweethayile. Ukukwazi kwayo ukuphucula ukubambelela, ukuguquguquka, ukunganyangeki kwamanzi, ukusebenza kakuhle, kunye nokuqina kwenza ukuba ibe yinto edityanisiweyo kwizinto zokwakha zanamhlanje. Ngokwenza ifilimu yepolymer eqhubekayo ngaphakathi kwe-matrix enamathelayo, i-RDP ibonelela ngeenzuzo eziyimfuneko kwimpumelelo yexesha elide lofakelo lweetayile. Njengoko ishishini lokwakha liqhubeka nokuvela, ukubaluleka kwe-RDP ekuqinisekiseni umgangatho ophezulu, ukuqina, kunye nokwakheka okuthembekileyo kokuncamatheliswa kweethayile kunokwenzeka ukuba kukhule, kuqhube ukuveliswa kwezinto ezintsha kunye neendlela eziphuculweyo zokwakha.
