Redispersible polymer powder (RDP) sisongezo esibalulekileyo kwizinto zokwakha zale mihla, ngakumbi kwizinto zokuncamathelisa, udaka, kunye neeplasta.Ngokwandisa iimpawu ezibonakalayo kunye neekhemikhali zezi zixhobo, ii-RDPs zidlala indima ebalulekileyo ekuphuculeni ukuqina kunye nokusebenza kweeprojekthi zokwakha.
Ukuqulunqwa kunye noBuchule be-RDP
I-RDP iveliswa ngokutshiza-yomisa i-emulsion yezinto zepolymeric, ngokuqhelekileyo zisekelwe kwi-vinyl acetate-ethylene (VAE), i-acrylic, okanye i-styrene-butadiene.Le nkqubo iguqula i-emulsion ibe ngumgubo ococekileyo onokuthi uphinde uhlakazwe emanzini, ukubuyisela kwakhona ukusabalalisa kwepolymer yasekuqaleni.Xa ifakwe kwimixube yodaka olomileyo, i-RDP iphinda isebenze xa idibene namanzi, idala ifilimu ene-homogeneous kunye nezinzile ngaphakathi kwe-matrix enamathelayo.
Ukwandiswa kokumelana naManzi
Ukuqulunqwa kwefilimu: Emva kokufakwa kwamanzi, amaqhekeza e-RDP adibanisa ukwenza ifilimu yepolymer eqhubekayo kuyo yonke i-matrix enamathelayo.Le filimu isebenza njengesithintelo, inciphisa kakhulu i-porosity kunye ne-permeability yamanzi ye-adhesive.Ifilimu ivala iziteshi ze-capillary, ukuthintela ukungena kwamanzi kunye nokuphucula i-adhesive's general waterproofing capabilities.
Iipropathi ze-Hydrophobic: Uninzi lwemixube ye-RDP lubandakanya ii-agent ze-hydrophobic okanye izilungisi ezongezelelisa ngakumbi ukuxhathisa kwamanzi.Ezi zixhobo ze-hydrophobic zinciphisa ukuxutywa kwamanzi kwi-adhesive, ukuqinisekisa ukusebenza kwexesha elide nakwiimeko ezimanzi.
Ukuphuculwa koBumbano kunye nokuguquguquka: i-RDP iphucula ukudibanisa kwangaphakathi kwe-adhesive, ukuphucula amandla ayo okudibanisa kunye nokuguquguquka.Oku bhetyebhetye kubalulekile ekuthinteleni ukwakheka kweentanda kunye nezithuba ezinokuvumela amanzi ukuba angene.I-adhesive enokuthi ikwazi ukunyuswa kwe-thermal kunye nokunciphisa ngaphandle kokuqhekeka igcina ingqibelelo yayo kunye nokuchasana kwamanzi ngokuhamba kwexesha.
Ukuphucula ukuxhathisa iMozulu
Uzinzo lwe-UV: Imixube ye-RDP kaninzi iyilelwe ukuxhathisa ukuthotywa kwe-ultraviolet (UV) ukukhanya.Ifilimu ye-polymer eyenziwe yi-RDP i-UV i-stable, ikhusela i-adhesive engaphantsi kwimiphumo eyingozi yokutshatyalaliswa kwelanga ixesha elide.Oku kuzinza kuqinisekisa ukuba i-adhesive igcina amandla kunye no-elasticity nasemva kokuvela kwexesha elide elangeni.
I-Thermal Resistance: Izinto zokwakha zixhomekeke kwiinguqu ezigqithisileyo zokushisa, ezinokubangela ukwanda kunye nokunciphisa.I-RDP-modified adhesives ibonisa ukuxhathisa kwe-thermal, ukugcina amandla abo ebhondi kunye nokuguquguquka kuluhlu olubanzi lobushushu.Le propati ithintela i-adhesive ekubeni i-brittle kwimozulu ebandayo okanye ithambile kakhulu kwiimeko ezishushu, ngaloo ndlela iphucula ukuxhathisa kwayo kwemozulu.
Ukumelana nemijikelo yokunyibilika komkhenkce: Kwimozulu ebanda kakhulu, izinto ezisetyenziswayo ziphinda-phinda zibe yimijikelo yokunyibilika komkhenkce, nto leyo enokuba yingozi kakhulu.Ukuguquguquka kunye nokubambisana okubonelelwa yi-RDP kunceda i-adhesives ukumelana nale mijikelezo ngaphandle kokulahlekelwa yingqibelelo.Ifilimu ye-polymer isebenza njengento yokufunxa ukothuka, ukunciphisa uxinzelelo olubangelwa ngumkhenkce kunye nokunyibilika.
Izicelo eziSebenzayo
I-Exterior Insulation and Finish Systems (EIFS): I-RDP isetyenziswa kakhulu kwi-EIFS, apho ukuxhathisa kwamanzi kunye nemozulu kubaluleke kakhulu.I-polymer powder iqinisekisa ukuba iileyile zokubambelela kwezi nkqubo ziyakwazi ukuxhathisa ukungena komswakama kunye nokumelana neemeko zemozulu ezahlukeneyo, ukukhusela ingqibelelo yesakhiwo kunye neempawu ze-insulation zenkqubo.
I-Tile Adhesives kunye neGrouts: Kuzo zombini izicelo zangaphakathi nangaphandle, i-tile adhesives kunye ne-grouts eguqulwe nge-RDP ibonisa ukusebenza okuphezulu.Baxhathisa ukungena kwamanzi kwaye banqande iithayile ukuba zikhululeke okanye zonakaliswe ngenxa yemozulu.Oku kubaluleke kakhulu kwiindawo zangaphandle apho iithayile zichaneke kwimvula, iqabaka, kunye nokukhanya kwelanga ngqo.
Ukulungisa i-Mortars kunye ne-Patching Compounds: Ukulungiswa kwekhonkrithi kunye nokudibanisa, i-RDP iphakamisa ukuqina kwezinto zokulungisa.Iqinisekisa ukuba ezi zixhobo zibophe ngokufanelekileyo kwikhonkrithi ekhoyo, inikezela ngesisombululo esingenamanzi kunye nemozulu echasene nemozulu eyongeza ixesha elide lokulungiswa.
IiNzuzo zokusiNgqongileyo nezoQoqosho
Ubomi Obongeziweyo: Ngokuphucula ukuxhathisa kwamanzi kunye nemozulu, i-RDP yandisa ubude bezinto zokuncamathelisa zokwakha kunye nezakhiwo ezisetyenziselwa kuzo. Oku kunciphisa imfuno yokulungiswa rhoqo kunye nokutshintshwa, okukhokelela ekunciphiseni iindleko zokugcina kunye nokusetyenziswa kobutyebi.
Ukusebenza kakuhle kwamandla: Kwizicelo ezifana ne-EIFS, i-RDP-i-adhesives ephuculweyo inegalelo ekusebenzeni kakuhle kwe-insulation ngokugcina ingqibelelo yenkqubo yokugquma.Oku kunokukhokelela ekugcinweni kwamandla okubalulekileyo ekufudumeni nasekupholiseni izakhiwo, ukukhuthaza ukuzinza.
Inkunkuma eNcitshisiweyo: Ukusetyenziswa kwezinto ezincamathelayo ezomeleleyo, ezikwaziyo ukumelana nemozulu kunciphisa inkunkuma yokwakha eyenziwa zizinto ezonakeleyo okanye ezonakeleyo.Oku kunegalelo kwimisebenzi yokwakha ezinzileyo kwaye kunciphisa impembelelo yokusingqongileyo yeeprojekthi zokwakha.
Umgubo wepolymer odispersible ulongezelelo oluguqukileyo kwizinto zokuncamathelisa zokwakha, ukunika amanzi abalulekileyo kunye neempawu zokumelana nemozulu.Ukukwazi kwayo ukwenza ifilimu yepolymer ekhuselayo, edityaniswa neempawu ze-hydrophobic kunye nokuguquguquka okuphuculweyo, kwenza i-RDP-modified adhesives yomelele ngokuchasene nemingeni yokufuma kunye nokuvezwa kwemozulu.Ngokudibanisa i-RDP kwizinto zokwakha, abakhi kunye neenjineli zinokuqinisekisa ukuba zihlala ixesha elide, izakhiwo ezihlala ixesha elide ezixhotyiswe ngcono ukumelana noxinzelelo lokusingqongileyo.Oku akuphuculi kuphela ukusebenza kunye nokuthembeka kweeprojekthi zokwakha kodwa kukwakhuthaza uzinzo kunye neendleko ezifanelekileyo kwishishini.
