Udaka lokwakha lusetyenziswa ngokubanzi kwizicelo ezahlukeneyo kushishino lokwakha ezifana nokutyabeka, ukubeka phantsi, iithayile kunye nokwakha, njl njl. Udaka ludla ngokuba ngumxube wesamente, isanti kunye namanzi axutywe ukwenza intlama.Kwiminyaka yakutshanje, kuye kwakho imfuno ekhulayo yezongezo eziphucula ukusebenza kodaka.I-polymer powder edispersible (RDP) yinto eyongeziweyo eyongeziweyo eyongezwa kwiidaka zokwakha ukunyusa iipropati zabo.Eli nqaku liza kubonelela ngombono wendima ye-RDP idispersible polymer izongezo zepolymer kwiidaka zokwakha.
Redispersible ipolymer powder yipolymer eyenziwe nge-ethylene-vinyl acetate copolymer, i-acrylic acid kunye ne-vinyl acetate.Ezi polymers zidityaniswe nezinye izongezo ezifana nezihluzi, i-thickeners kunye ne-binders ukuvelisa umgubo we-RDP.Iipowder ze-RDP zisetyenziselwa ukuveliswa kwezinto ezininzi zokwakha ezibandakanya i-adhesives tile, i-samente-based mortars kunye nee-agent zokulinganisa.
Enye yeenzuzo eziphambili zokusebenzisa i-RDP kwiidaka zokwakha kukuba iphucula ukusebenza kodaka.I-RDP ikwandisa ukuhambelana kodaka, okwenza kube lula ukuyifaka kunye nokusabalalisa.Ukuphuculwa kokuqhubela phambili kukwathetha ukuba amanzi amancinci afunekayo ukufezekisa ukungaguquguquki okufunekayo.Oku kwenza ukuba udaka luxhathise ngakumbi ukuqhekeka kunye nokushwabana, nto leyo eyenza ukuba lomelele kwaye luhlale ixesha elide.
Enye inzuzo ebalulekileyo yokusebenzisa i-RDP kwiimbumba zokwakha kukuba iphucula ukunamathela kodaka.Ukuncamathela okuphuculweyo kuthetha ukuba udaka lwenza iqhina elomeleleyo kunye nomphezulu wokusebenza okungcono kunye nokuqina.I-RDP ikwaphucula iipropati zokugcina amanzi kudaka, inceda ukuthintela ilahleko yamanzi ngexesha lolwakhiwo.Oku kuvumela udaka ukuba lusete kwaye lube lukhuni ngokulinganayo, luqinisekisa ukusebenza okufanayo kunye nokuqina.
I-RDP iphinda ikhulise ukuguquguquka kodaka, okwenza kube lula ukujamelana noxinzelelo lwexesha elide kunye noxinzelelo.Ukunyuka kokuguquguquka kodaka kuthetha ukuba kulula ukukrazula kunye nokuqhekeka naxa ubonakaliswe kwiimeko ezinzima zokusingqongileyo.Oku kuguquguquka okuphuculweyo kukwathetha ukuba udaka lusebenza ngeendlela ezininzi kwaye lunokusetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa nemiphezulu engalinganiyo kunye negophe.
Ukusetyenziswa kwe-RDP kudaka lokwakha kwakhona kwandisa amandla oxinzelelo lodaka.Amandla acinezelayo yipropathi ephambili yokwakha udaka njengoko imisela indlela udaka oluchasa ngayo ukuguqulwa kunye nokuqhekeka phantsi komthwalo.I-RDP yonyusa amandla oxinzelelo lodaka, iyenza ikwazi ukumelana nemithwalo enzima kunye nokunciphisa amathuba okuqhekeka kunye nomonakalo.
Isishwankathelo, ukusetyenziswa kwe-RDP yokongeza i-polymer eyongezelelweyo ye-polymer kwi-mortars yokwakha inika uluhlu lweenzuzo ezinokuphucula ukusebenza kunye nokuqina kodaka.I-RDP iphucula ukusebenza, ukunamathela, ukugcinwa kwamanzi, ukuguquguquka kunye namandla oxinzelelo lodaka, okwenza kube yinto eguquguqukayo kwaye ifanele uluhlu olubanzi lwezicelo.Ukusebenzisa i-RDP kudaka lolwakhiwo kuvelisa imveliso esebenzayo, engabiziyo kwaye ehlala ixesha elide, nto leyo eyenza ukuba ibe lukhetho olwandayo oluthandwa ngabakhi kunye neekontraka.
