I-redispersible polymer powder (RDP) i-polymer powder esetyenziswa ngokubanzi kwishishini lokwakha ukuphucula iipropati zodaka kunye nezinye izinto ze-cementitious.Xa ifakwe kwimixube yodaka, i-RDP inceda ukudala ubumbano oluqinileyo okwandisa ubunzima bezinto eziphathekayo, ukuqina kunye nokuchasana nemozulu, ukuqhekeka kunye nokuhlaselwa kweekhemikhali.Eli nqaku liza kugxininisa kwimiphumo emihle ye-RDP kwiidaka ezinobunzima, kubandakanywa amandla okunyusa amandla, ukuphucula ukudibanisa, ukuphucula ukusebenza, kunye nokunciphisa ukucutheka.
ukwandisa amandla
Enye yeenzuzo eziphambili ze-RDP phezu kodaka oluqinileyo kukukwazi ukunyusa amandla ezinto eziphathekayo.Oku kuphunyezwa ngokuphucula i-hydration kunye nokunyangwa kweengqungquthela ze-samente, okubangelwa yi-denser kunye ne-denser material.Iipolymers kwi-RDP zisebenza njengesibophelelo, zizalise izithuba phakathi kwamasuntswana esamente kwaye zenze ibhondi eyomeleleyo.Isiphumo singudaka olunamandla aphezulu oxinzelelo kunye nokuqina, okwenza ukuba luxhathise ngakumbi kuxinzelelo, impembelelo kunye noguquko.
ukunamathela okongeziweyo
Esinye isiphumo esihle se-RDP kudaka oluqinileyo kukukwazi ukomeleza ukuhlangana.I-RDP isebenza njenge-ejenti yokudibanisa phakathi kweengqungquthela ze-samente kunye ne-substrate surface, ukuphucula ukunamathela phakathi kwezinto ezimbini.Oku kubaluleke kakhulu kwizicelo ezifana ne-tile, apho udaka lufuna ukunamathela kwi-substrate kunye nomphezulu we-tile.I-RDP iqinisekisa ibhondi eyomeleleyo nehlala ixesha elide enokumelana noxinzelelo kunye noxinzelelo lokusetyenziswa kwemihla ngemihla.
Ukuphucula ukusebenza
I-RDP ikwaphucula ukusebenza kodaka, okwenza kube lula ukuxuba, ukusebenzisa nokugqiba.Iipholima kwi-RDP zisebenza njengezithambiso, zinciphisa ukukhuhlana phakathi kwamasuntswana esamente ukuze zihambe ngokukhululekileyo.Oku kwenza ukuba udaka lube nolwelo ngakumbi kwaye kube lula ukusebenza ngalo, okukhokelela kulwakhiwo olugudileyo kunye nokugubungela ngokubanzi.Isiphumo sisixhobo esineempawu ezihambelanayo kunye nesicelo esilula kuluhlu olubanzi lweemeko.
ukunciphisa ukucutheka
Omnye wemiceli-mngeni ekusebenzeni ngodaka kukuba ithande ukucutheka njengoko isoma kwaye iphilisa.I-Shrinkage inokubangela ukuqhekeka kwezinto eziphathekayo, ukuphazamisa ukuzinza kwayo kunye nokuqina.I-RDP inokunceda ukunciphisa ukucutheka ngokulawula ukomisa kunye nokunyanga inkqubo yezinto.Iipolymers kwi-RDP zenza ifilimu ejikeleze amaqhekeza e-samente asebenza njengomqobo ekulahlekeni komswakama.Oku kunciphisa inkqubo yokomisa kwaye kuvumela amanzi ukuba asasazeke kangcono kuyo yonke into, ukunciphisa ithuba lokunciphisa kunye nokuqhekeka.
ukuququmbela
Iziphumo ezilungileyo zeRDP kudaka oluqinileyo zininzi kwaye zibalulekile.Xa ifakwe kwimixube yodaka, i-RDP yonyusa amandla, ikhulisa iibhondi, iphucula ukusebenza kakuhle kwaye inciphisa ukushwabana.Ezi nzuzo zenza i-RDP ibe sisixhobo esixabiseke kakhulu kwiingcali zokwakha ezifuna ukwakha izakhiwo nezakhiwo ezikumgangatho ophezulu, ezihlala ixesha elide nezihlala ixesha elide.Njengoko ishishini lokwakha liqhubeka nokuvela kwaye kuvela izixhobo ezintsha kunye nobuchwepheshe, iRDP iya kuhlala iyinxalenye ebalulekileyo yabakhi kunye neekontraka kwihlabathi liphela.
