Umgubo wePolymer ophinda unyibilike (RDP), njengesongezelelo esibalulekileyo sepolymer, isetyenziswa kakhulu kwiminyaka yakutshanje kwi-dry-mix mortar, i-tile adhesive, i-putty powder, i-plastering mortar, kunye ne-grout. Ukusetyenziswa kwayo kwi-tile grout kubaluleke kakhulu ekuphuculeni amandla e-bond, ukuguquguquka, ukumelana nokuqhekeka, kunye nokumelana namanzi.
1. Indlela yokusebenza ye-RDP
I-RDP yimpuphu ephinda inyibilike eyenziwe nge-polymer emulsion ngenkqubo yokomisa ngokutshiza, eneempawu zokuphinda inyibilike xa idibana namanzi. Xa i-RDP yongezwa kwi-grout, njengoko amanzi ephuma ngexesha lokwakhiwa, amasuntswana e-RDP ayaphinda anyibilike ukuze enze ifilimu ye-polymer eqhubekayo. Le filimu ye-polymer idibana neemveliso zokufunxa isamente, yenze "inkqubo ye-inorganic-organic composite," iphucula kakhulu iipropati zoomatshini zezinto kunye neempawu zokubopha phakathi kobuso.
Ngexesha lenkqubo yokunyanga i-grout, ifilimu ye-RDP polymer inokugquma amasuntswana okuzalisa, iphucule ukunamathelana kwe-interfacial kwaye inciphise ukubola kwenkqubo esekelwe kwisamente. Ngaphezu koko, amacandelo aguquguqukayo kwiimolekyuli ze-RDP anika i-grout inqanaba elithile lokuguquguquka kunye nokumelana nokuguquguquka, okuthintela ngempumelelo ukuqhekeka okubangelwa kukutshintsha kobushushu okanye ukuguqulwa kwe-substrate.
2. Ukuphuculwa kwe-RDP kokusebenza kweTile Grout
2.1. Ukomelela kweBond okuPhuculweyo
Eyona mfuneko iphambili ye-tile grout kukunamathela kakuhle kwimiphetho ye-tile kunye ne-substrate. I-RDP yenza ifilimu ye-polymer yendalo, eyenza ujongano phakathi kwe-grout esekelwe kwisamente kunye nomphezulu we-tile zibotshelelwe ngokuqinileyo. Kwangaxeshanye, intsalela ye-polymer emva kwe-hydration reaction ye-RDP yonyusa uxinano lomaleko we-interface, ngaloo ndlela iphucula kakhulu amandla e-grout kunye nokuqina kwayo.
2.2. Ukuguquguquka Okuphuculweyo kunye nokumelana nokuqhekeka
Ii-grout zesintu ezisekwe kwisamente zinokuba neentanda ezincinci xa zomisa zincipha okanye zitshintsha ubushushu, nto leyo echaphazela ubuhle kunye nokusebenza kokuthintela amanzi. Ukungeniswa kwezinto zepolymer kwi-RDP kuphucula ukuguquguquka kunye nokuqina kwezinto, okuvumela umaleko we-grout ukuba umelane noxinzelelo oluthile kunye nokuguquguquka ngaphandle kokuqhekeka, ngaloo ndlela wandise ubomi bawo benkonzo.
2.3. Ukuphuculwa kokungangenwa kwamanzi kunye nokungangeni kwamanzi
Ifilimu yepolymer eqhubekayo eyenziwe yiRDP ine-permeability ephantsi, ithintela ngokufanelekileyo ukungena kwamanzi kwaye inciphisa ukufunxwa kwamanzi. Le mpawu ibaluleke kakhulu kwiindawo ezimanzi ezifana neekhitshi kunye namagumbi okuhlambela, ithintela ngokufanelekileyo ukufuma ekungeneni ngasemva kweethayile okanye kwi-substrate ecaleni kwezithuba, inciphisa umngcipheko wokungunda kunye nokuqhekeka.
2.4. Ukumelana nokukrala okuphuculweyo kunye nokumelana namabala
I-RDP esemgangathweni ophezulu iphucula uxinano lomphezulu we-grout, iyenza igude, imelane nokukrweleka ngakumbi, kwaye inciphise ukunamathela kothuli. I-grout eguqulwe yi-RDP ayithambekeli kakhulu ekuqokeleleni uthuli okanye ekutshintsheni umbala ngexesha lokucoca imihla ngemihla, igcina ubuhle bayo ixesha elide.
2.5. Ukusebenza okuPhucukileyo kweSicelo
I-RDP iphucula kakhulu ukuhamba kokufakwa kunye nokugcinwa kwamanzi kwi-grout, yenza ukusetyenziswa kube lula, kube lula ukuvala izikhewu, kwaye kunciphisa imingxuma kunye namaqamza omoya. Kwangaxeshanye, isiphumo sayo sokugcina amanzi sinciphisa izinga lokufuma kwesamente, sinike abasebenzi ixesha elingakumbi lokufaka kunye nokuphucula umgangatho kunye nokusebenza kakuhle kokusetyenziswa.
3. Ukusebenza kwesicelo se-RDP kwiintlobo ezahlukeneyo ze-Grout
3.1. I-Grout Esekelwe Kwisamente
Ukongeza i-RDP kwi-grout eqhelekileyo esekelwe kwisamente kuphucula kakhulu ukunamathela kunye nokumelana nokuqhekeka, okwenza ukuba ifaneleke ngakumbi kwi-grouting ngaphakathi nangaphandle kweethayile zodonga kunye nomgangatho.
3.2. I-Epoxy okanye i-High-Performance Grout
Kwimixube ye-grout ephezulu efuna ukumelana nokuguguleka okuphezulu kunye nokungangeni kwamanzi, i-RDP, njengesiguquli, isebenza kunye nezinye iiresins ukuphucula ukuguquguquka kunye nokunamathela.
3.3. I-Grout enemibala
Iimpawu zokwenza ifilimu ye-RDP zinceda ukuqinisekisa ukusasazwa kombala okufanayo, ziphucula ukuqina kombala, zithintele umahluko wombala kunye nokuqaqamba, kwaye zenze ii-grouts ezinemibala zihombise ngakumbi.
4. Ixabiso lesicelo kunye neendlela zophuhliso lwe-RDP
Ngamafutshane, ixabiso lokusetyenziswa kwe-RDP kwi-grout yethayile libonakala kakhulu kwezi zinto zilandelayo:
Uzinzo oluphuculweyo lokusebenza kwemveliso: Ngokuphucula ukunamathela, ukuthintela amanzi, kunye nokuguquguquka, i-grout igcina ukusebenza kakuhle kwiindawo ezahlukeneyo.
