Udaka oluxubeneyo olomileyo lufuna iindidi ezahlukeneyo zokudibanisa kunye neendlela ezahlukeneyo zesenzo ukuze zihambelane, kwaye zinokulungiswa kuphela ngenani elikhulu leemvavanyo. Xa kuthelekiswa nemixube yekhonkrithi yemveli, imixube yodaka eyomileyo exutyiweyo ingasetyenziswa kuphela kwifom yomgubo, kwaye okwesibini, inyibilika emanzini abandayo, okanye inyibilike ngokuthe ngcembe phantsi kwesenzo sealkali ukwenza isiphumo sayo esifanelekileyo.
Umsebenzi oyintloko we-latex powder owenziwe ngokutsha kukuphucula ukugcinwa kwamanzi kunye nokuzinza kodaka. Nangona inokuthintela ukuqhekeka kodaka (ukunciphisa isantya somphunga wamanzi) ukuya kumlinganiselo othile, ngokuqhelekileyo ayisetyenziswa njengendlela yokuphucula ukuqina kodaka, ukumelana nokuqhekeka kunye nokuxhathisa kwamanzi.
Ukongeza i-polymer powder kunokuphucula ukunganyanzeki, ukuqina, ukuxhathisa ukuqhekeka kunye nokuchasana kwempembelelo yodaka kunye nekhonkrithi. Ukusebenza kwepowder ye-latex e-dispersible izinzile, kwaye inefuthe elihle ekuphuculeni amandla okubambisana omdaka, ukuphucula ukuqina kwayo, ukukhubazeka, ukuchasana nokuqhekeka kunye nokungathinteki. Ukongeza i-hydrophobic latex powder kunokunciphisa kakhulu ukufunxwa kwamanzi kodaka (ngenxa ye-hydrophobicity yayo), ukwenza udaka luphefumle kwaye lungakwazi ukungena emanzini, luphucule ukuxhathisa kwemozulu, kunye nokuphucula ukuqina kwalo.
Xa kuthelekiswa nokuphucula amandla okuguquguquka kunye nokuqina kokubambisana komdaka kunye nokunciphisa ukunyanzeliswa kwayo, umphumo we-latex powder owenziwe ngokutsha ekuphuculeni ukugcinwa kwamanzi kunye nokudibanisa komdaka kulinganiselwe. Ekubeni ukongezwa kwe-latex powder ehlaziywayo kunokusabalalisa kwaye kubangele ubuninzi be-air-entrainment kumxube wodaka, umphumo walo wokunciphisa amanzi ubonakala kakhulu. Ngokuqinisekileyo, ngenxa yesakhiwo esibi se-bubbles emoyeni esaziswayo, umphumo wokunciphisa amanzi awuzange uphucule amandla. Ngokuchasene noko, amandla omdaka aya kuncipha ngokuthe ngcembe ngokunyuka kwe-latex powder content content. Ngoko ke, ekuphuhlisweni kwamanye ama-mortars adinga ukuqwalasela amandla okunyamezela kunye nokuguquguquka, kudla ngokuyimfuneko ukongeza i-defoamer ngexesha elifanayo ukuze kuncitshiswe impembelelo engalunganga ye-latex powder kumandla oxinzelelo kunye namandla aguquguqukayo omdaka. .
