Umgubo wepolymer ophinda uqhekeke (RDP), njengesongezo esiphambili se-organic kwiimortars zanamhlanje ezomileyo, isetyenziswa kakhulu kwiinkqubo ezahlukeneyo ezifana nezincamathelisi zethayile, iipowders ze-putty, iimortars zokukhusela udonga lwangaphandle, iimortars ezizilinganisayo, kunye neemortars ezingangeni manzi ngenxa yeempawu zayo ezintle zokubopha, ukuguquguquka, kunye nokukwazi ukuguqula. Ngokuyintloko, yipowder eqinileyo eyenziwe ngokutshiza i-polymer emulsion. Xa idibana namanzi, inokuphinda ichitheke ibe yi-emulsion ezinzileyo, ngaloo ndlela yenze ifilimu ye-polymer eqhubekayo ngexesha lenkqubo yokuqinisa imortar, iphucula kakhulu ukusebenza kwemortar iyonke.
1. Indlela ephambili ye-RDP ekuPhuculeni ukusebenza kweMortar
1.1. Ukuphucula Amandla eBond
Ifilimu yepolymer eyenziwe yi-RDP emva kokuqina kwe-mortar inomqamelo ophezulu kunye nokuqina okuhle, yenza ibhulorho eqinileyo yokubopha kumphezulu we-substrate, iphucula kakhulu ukunamathelana phakathi kwe-mortar kunye nezinto ezifana nekhonkrithi, izitena, iibhodi ze-EPS, kunye neethayile. Indima ye-RDP ibaluleke kakhulu kwi-substrates ezifunxa kancinci okanye ezigudileyo.
1.2. Ukuguquguquka Okuphuculweyo kunye nokumelana nokuqhekeka
Izinto zesintu ezisekelwe kwisamente zibuthathaka kakhulu kwaye zinoqhekeko ngenxa yokutshintsha kobushushu kunye nokuguquguquka kwesiseko sezinto. I-polymer ekwi-RDP isasazeka kwiimbobo zesamente, yenze isakhiwo senethiwekhi esiguquguqukayo, inciphisa i-elastic modulus yento, kwaye yonyusa ukumelana kwayo nokuguquguquka, ngaloo ndlela iphucula kakhulu ukumelana nokuqhekeka kwesamente.
1.3. Ukuphuculwa Kokusebenza
I-RDP yenza i-mortar ibe mhle kwaye igudileyo, iphucula ukusebenza kwayo kunye nokuziva kwayo. Ukugcinwa kwamanzi okuphuculweyo kunye nexesha elide lokuvula kwenza kube lula ukwakhiwa kwayo, kwandisa ukusebenza kakuhle kunye nozinzo lomgangatho.
1.4. Ukumelana Okuphuculweyo Kwamanzi Nemozulu
Ifilimu yepolymer inokumelana kakuhle kwamanzi kunye nokumelana namanzi, inciphisa ukufunxwa kwamanzi yimortar kwaye ngaloo ndlela iphucula ukumelana nokufuma kunye nokunyibilika kwemijikelo yokukhenkceza. Kwiindlela zokusetyenziswa kodonga lwangaphandle, i-RDP inceda ukuphucula ukumelana nemozulu kweengubo kunye neemortar, igcina uzinzo lwazo phantsi kokuvezwa ixesha elide.
2. Ukusetyenziswa kweRedispersible Polymer (RDP) kwiiNkqubo ezahlukeneyo zeMortar
2.1. Isincamathelisi sethayile
I-RDP yinxalenye ebalulekileyo ye-adhesive yethayile, iphucula kakhulu ukunamathela, iimpawu ezingatyibiliki, kunye nokuguquguquka. Kwiithayile ezinkulu, iithayile ezifunxa kancinci, okanye iithayile ezine-vitrified, umxholo ophezulu we-polymer i-RDP iqinisekisa ukubopha okuqinileyo kwaye ithintela iindawo ezingenanto kunye nokuqhekeka.
2.2. I-mortar yokukhusela udonga lwangaphandle (i-EPS/XPS Adhesive, i-Finishing Mortar)
Kwiinkqubo zokwambathisa ubushushu, i-RDP inika ukuguquguquka okufunekayo kunye namandla okubopha, ivumela i-mortar ukuba inamathele ngokuqinileyo kwiibhodi ze-EPS/XPS. Ikwaphucula ukumelana nokuqhekeka kunye nokumelana nempembelelo yomaleko wokugqiba, iqinisekisa uzinzo lwexesha elide lwenkqubo yokwambathisa ubushushu.
2.3. I-mortar engangeni manzi
I-RDP yenza ifilimu ye-polymer exineneyo ngaphakathi kwi-mortar, inciphisa ukubola kwe-capillary kwaye iphucula ukungakwazi ukungena. Isebenza ngokubambisana neemveliso zokufunxa isamente, iphucula kakhulu ukuguquguquka kunye nokuqina komaleko ongangeni manzi.
2.4. I-mortar eZilinganiselayo
Kwiinkqubo zokuzilinganisa, i-RDP iphucula amandla okuqala, ukutyibilika, kunye neempawu zokubopha ze-mortar ngelixa inciphisa ukuqhekeka, nto leyo ekhokelela kulwakhiwo oluzinzileyo lomgangatho kunye namandla aphezulu omphezulu.
2.5. Umgubo wePutty
Ukongeza i-RDP kwi-putty powder kuphucula ukunamathela, iimpawu zokulwa nokutshixa, kunye nokuziva utyibiliza, nto leyo ebangela ukuba umphezulu wodonga ube bushelelezi, ucoceke ngakumbi kwaye ukhuseleke ngakumbi emanzini kwaye uhlale ixesha elide.
2.6. Iarhente yokulungisa i-mortar kunye ne-interface
I-RDP iphucula ukunamathela kunye nokumelana nokuqhekeka kwezinto zokulungisa, nto leyo eyenza ukuba zihlale zizinzile kwaye zithembeke ngakumbi kwizicelo ezifana nokulungiswa kwekhonkrithi endala kunye nokulungiswa kwe-interface.
3. Amanyathelo okuzikhusela xa usebenzisa iPowder yePolymer ephinda isasazeke
Khetha efanelekileyoI-RDPuhlobo kunye nomthamo osekelwe kumsebenzi wenkqubo yodaka;
Ukudibanisa nee-ether ze-cellulose (HPMC/MHEC), ii-ether ze-starch, njl.njl., kunokuphucula ukugcinwa kwamanzi, ukusebenza kakuhle, kunye nokumelana nokuwa;
Gcina kwindawo eyomileyo ukuze uphephe ukufuma nokuxinana;
Qinisekisa ukuba usasazeke kakuhle ngexesha lokuxuba ukuze kufezekiswe ukusebenza okuzinzileyo.
