Impuphu ye-polymer ephinde ihlakazeke (RDP)uhlobo lwesithako sempuphu ye-polymer esenziwe nge-polymer emulsion ngokufutha nge-spray. Isici sayo esiyinhloko yikhono layo lokuphinde lihlakazeke libe yi-polymer emulsion ezinzile lapho ihlangana namanzi, ngaleyo ndlela yenza umsebenzi wokuguqula ofana nowe-liquid emulsion ezinhlelweni ezahlukene ze-dry-mix mortar. Ukwethulwa kwe-RDP kuthuthukise kakhulu ukusebenza, ukunamathela, kanye nokuqina kwezinto zokwakha, okwenza kube yingxenye ebalulekile ebalulekile ekwakhiweni kwe-dry-mix mortar yesimanje kanye ne-tile adhesive.
1.Ngokuphathelene nezici zokusebenza, i-RDP ikhombisa ukuphinde ihlakazeke kahle kanye nezakhiwo zokwakha ifilimu. Uma ixutshwa ngamanzi, i-RDP powder isakazeka ngokushesha ukuze yakhe izinhlayiya ze-emulsion ezifanayo, futhi ngesikhathi senqubo yokomisa, yakha ifilimu ye-polymer eqhubekayo, eqinile. Le filimu ye-polymer ibopha ngempumelelo i-inorganic aggregate ebusweni be-substrate, ithuthukise amandla e-bond kanye nokuguquguquka kwezinto. Ingqimba yefilimu nayo inezinga elithile lokunwebeka, imunca umehluko wokucindezeleka phakathi kwezingqimba zesisekelo nezendlalelo eziphezulu, ivimbele ukuqhekeka nokuchitheka.
2.I-RDP ingathuthukisa kakhulu ukusebenza kahle kwe-mortar. Ukwengeza inani elifanele le-RDP kuthuthukisa kakhulu ukugcinwa kwamanzi kwe-mortar, ukugeleza, kanye nokuthamba, okwenza kube lula futhi kube ngokulinganayo ngenkathi kunciphisa ukopha kanye nokwehlukaniswa. Ngaphezu kwalokho, i-RDP ithuthukisa izakhiwo ze-mortar zokulwa nokuwa kanye nokulwa nophuphu, okwenza ukusetshenziswa kwe-mortar kube okuqinile kube okuzinzile. Kuma-adhesive e-tile, i-RDP iqinisa isibopho phakathi kwe-tile kanye ne-substrate, iqinisekisa ukuzinza kokunamathela kwesikhathi eside.
3.Ngokuphathelene nokuqina, i-RDP ibonisa ukumelana okuhle kakhulu nokuqhekeka, ukumelana nokuqandisa, kanye nokumelana nokuguquguquka kwesimo sezulu. Ifilimu ye-polymer isebenza njengesivikelo kumswakama namagesi, inciphisa ukungena komswakama wangaphandle futhi ngaleyo ndlela yehlisa ukuguga kwe-mortar. Ngisho nangaphansi kwemijikelezo eshisayo nebandayo noma ezindaweni ezinomswakama, izinto eziguqulwe yi-RDP zigcina amandla aphezulu kanye nokunamathela, okubaluleke kakhulu ezinhlelweni zokuvikela udonga lwangaphandle kanye nokulungisa i-mortar.
4.Ngokwekhemikhali, i-RDP ngokuvamile iyi-copolymer yama-monomers ahlukene, njenge-vinyl acetate-ethylene (VAE), ama-acrylates, kanye ne-styrene-butadiene. Izinhlobo ezahlukene zama-polymer zinquma ibhalansi phakathi kokuguquguquka, ukumelana namanzi, kanye nokunamathela. Ama-RDP asekelwe ku-VAE yiwona asetshenziswa kakhulu ngenxa yokusebenza kwawo okuhle kakhulu. Ama-RDP asekelwe ku-acrylate adumile ngokumelana kwawo nesimo sezulu okuhle kakhulu kanye nokuguquguquka, okwenza afaneleke ezintweni zodonga zangaphandle ezisezingeni eliphezulu. Ama-RDP asekelwe ku-styrene-butadiene avame ukusetshenziswa ezinhlelweni ezidinga ukuguquguquka okuphezulu kanye nokumelana nokuhuzuka.
5.Ezisetshenzisweni ezisebenzayo, ama-RDP asetshenziswa kabanzi ekwakhiweni okufana nama-tile anamathelayo, izinhlelo zokufaka izinto zangaphandle (i-EIFS), ama-self-leveling mortars, ama-repair mortars, ama-plaster mortars, ama-waterproofing mortars, kanye nama-interface agents. Isibonelo, kuma-tile anamathelayo, ama-RDPs athuthukisa kakhulu amandla okubopha okomile nokumanzi kanye nezakhiwo zokungasheleli; kuma-insulation mortars, athuthukisa ukuguquguquka kwesistimu kanye nokumelana nokuqhekeka; kuma-self-leveling mortars, ama-RDPs athuthukisa ukugeleza futhi anciphise ufulawa; kanti kuma-waterproofing mortars, athuthukisa ukungangeni kwamanzi kanye nobude, aqinisa izakhiwo zawo zokuvikela.
6.Ngenxa yezakhiwo zayo ezinhle kakhulu zokwakha ifilimu ye-polymer kanye nomphumela wokubambisana nezingxenye ezingaphili,I-RDPkuthuthukisa kakhulu ukusebenza kwezinhlelo zodaka oluxutshwe okomile. Akugcini nje ngokuthuthukisa ulwazi lokwakha kodwa futhi kunikeza ukuqina okukhulu kanye nokuzivumelanisa nezimo nezinto, okwenza kube yisithasiselo esibalulekile sokufeza ukusebenza okuphezulu kanye nokuzinza ezintweni zokwakha zesimanje. Ngokuthuthuka okuqhubekayo kwezinto zokwakha eziluhlaza kanye nezinhlelo zokuxuba okomile ezisebenza kahle, ukusungula ubuchwepheshe be-RDP kanye nobubanzi bokusetshenziswa kuzoqhubeka nokukhula, kube yisiqondiso esibalulekile sezinto zokwakha ezisebenzayo zesikhathi esizayo.
