Umgubo wepolymer ophinda uqhekeke (RDP)luhlobo lwesongezo se-polymer powder esenziwe nge-polymer emulsion ngokufutha nge-spray. Uphawu lwayo oluphambili kukukwazi kwayo ukuphinda inyibilike ibe yi-polymer emulsion ezinzileyo xa idibana namanzi, ngaloo ndlela yenza umsebenzi wokuguqula ofana nowe-liquid emulsion kwiinkqubo ezahlukeneyo ze-dry-mix mortar. Ukwaziswa kwe-RDP kuphucule kakhulu ukusebenza, ukunamathela, kunye nokuqina kwezixhobo zokwakha, okwenza ukuba ibe yinxalenye ebalulekileyo kwi-dry-mix mortar yanamhlanje kunye ne-tile adhesive formulations.
1.Ngokweempawu zokusebenza, i-RDP ibonakalisa iimpawu ezibalaseleyo zokukwazi ukuphinda inyibilike kwaye ikwazi ukwenza ifilimu. Xa ixutywe ngamanzi, umgubo we-RDP usasazeka ngokukhawuleza ukuze wenze amasuntswana e-emulsion afanayo, kwaye ngexesha lenkqubo yokomisa, yenza ifilimu ye-polymer eqhubekayo, exineneyo. Le filimu ye-polymer ibopha ngokufanelekileyo i-inorganic aggregate kumphezulu we-substrate, iphucula amandla e-bond kunye nokuguquguquka kwezinto. Umaleko wefilimu ukwanalo nomlinganiselo othile wokuqina, ufunxa umahluko woxinzelelo phakathi kwesiseko kunye namaleya aphezulu, uthintela ukuqhekeka nokuqhekeka.
2.I-RDP inokuphucula kakhulu ukusebenza kakuhle kwe-mortar. Ukongeza ubungakanani obufanelekileyo be-RDP kuphucula kakhulu ukugcinwa kwamanzi kwi-mortar, ukunyibilika, kunye nokuthamba kwayo, okwenza ukuba isetyenziswe kakuhle kwaye ilingane ngakumbi ngelixa kunciphisa ukopha kunye nokwahlukana. Ngaphezu koko, i-RDP iphucula iipropati ze-mortar zokulwa nokuwa kunye nokungaguquguquki komgubo, okwenza ukusetyenziswa kwe-maleage etyebileyo kuzinze ngakumbi. Kwizinto zokuncamathelisa iithayile, i-RDP iqinisa unxibelelwano phakathi kwethayile kunye ne-substrate, iqinisekisa uzinzo lokunamathela ixesha elide.
3.Ngokuphathelele ukuqina, i-RDP ibonakalisa ukumelana okuhle kakhulu nokuqhekeka, ukumelana nokuqandusela komkhenkce, kunye nokumelana nokuguquguquka kwemozulu. Ifilimu ye-polymer isebenza njengomqobo kumswakama kunye neegesi, inciphisa ukungena komswakama wangaphandle kwaye ngaloo ndlela inciphisa ukuguga kwe-mortar. Nokuba phantsi kwemijikelo eshushu nebandayo okanye kwiindawo ezifumileyo, izinto eziguqulwe yi-RDP zigcina amandla aphezulu kunye nokunamathela, okubaluleke kakhulu kwiinkqubo zokukhusela udonga lwangaphandle kunye nee-mortar zokulungisa.
4.Ngokwekhemikhali, i-RDP idla ngokuba yi-copolymer yee-monomers ezahlukeneyo, ezifana ne-vinyl acetate-ethylene (VAE), ii-acrylates, kunye ne-styrene-butadiene. Iindidi ezahlukeneyo zee-polymers zimisela ibhalansi phakathi kokuguquguquka, ukumelana namanzi, kunye nokunamathela. Ii-RDPs ezisekwe kwi-VAE zezona zisetyenziswa kakhulu ngenxa yokusebenza kwazo okuhle kakhulu. Ii-RDPs ezisekwe kwi-acrylate ziyaziwa ngokumelana kwazo okuhle kakhulu kwemozulu kunye nokuguquguquka, okwenza zifaneleke kwizixhobo zodonga lwangaphandle eziphezulu. Ii-RDPs ezisekwe kwi-styrene-butadiene zihlala zisetyenziswa kwiinkqubo ezifuna ukuthamba okuphezulu kunye nokumelana nokukrala.
5.Kwizicelo ezisebenzayo, ii-RDP zisetyenziswa kakhulu kwiifomyula ezifana nezincamathelisi zethayile, iinkqubo zokugquma zangaphandle (ii-EIFS), ii-mortar ezizilinganisayo, ii-mortar zokulungisa, ii-mortar zeplasta, ii-mortar zokuthintela amanzi, kunye nee-interface agents. Umzekelo, kwii-adhesive zethayile, ii-RDP ziphucula kakhulu amandla okubopha okomileyo nokumanzi kunye neempawu zokungatyibiliki; kwii-mortar zokuthintela amanzi, ziphucula ukuguquguquka kwenkqubo kunye nokumelana nokuqhekeka; kwii-mortar ezizilinganisayo, ii-RDP ziphucula ukuhamba kwamanzi kwaye zinciphisa umgubo; kwaye kwii-mortar zokuthintela amanzi, ziphucula ukungangeni kwamanzi kunye nobude, ziqinisa iimpawu zazo zokukhusela.
6.Ngenxa yeempawu zayo ezintle zokwenza ifilimu yepolymer kunye nefuthe layo lokusebenzisana kunye ne-inorganic substrates,I-RDPiphucula kakhulu ukusebenza kweenkqubo zedaka ezixutywe nodaka. Ayipheleli nje ekuphuculeni amava okwakha kodwa ikwanika ukuqina okukhulu kunye nokuzivumelanisa nezimo nezixhobo, nto leyo eyenza ukuba ibe sisongezelelo esibalulekileyo sokufezekisa ukusebenza okuphezulu kunye nokuzinza kwizixhobo zokwakha zanamhlanje. Ngophuhliso oluqhubekayo lwezixhobo zokwakha eziluhlaza kunye neenkqubo zedaka ezixutywe nodaka ezisebenza kakhulu, uyilo lwetekhnoloji ye-RDP kunye nobubanzi besicelo ziya kuqhubeka nokukhula, zibe sisikhokelo esiphambili sezixhobo zokwakha ezisebenzayo kwixesha elizayo.
