Udaka oluxutshwe okomile ludinga izinhlobo ezahlukene zezingxube ezinezindlela ezahlukene zokusebenza ukuze zifane, futhi zingalungiselelwa kuphela ngenani elikhulu lokuhlola. Uma kuqhathaniswa nezixube zendabuko zikakhonkolo, izingxube zodaka ezixubene ezomile zingasetshenziswa kuphela kwifomu lempushana, futhi okwesibili, ziyancibilika emanzini abandayo, noma zincibilike kancane kancane ngaphansi kwesenzo se-alkali ukuze zenze umphumela wazo ofanele.
Umsebenzi oyinhloko we-latex powder ehlakazeka kabusha ukuthuthukisa ukugcinwa kwamanzi nokuzinza kodaka. Nakuba ingavimbela ukuqhekeka kodaka (yehlisa izinga lokuhwamuka kwamanzi) ngokwezinga elithile, ngokuvamile ayisetshenziswa njengendlela yokuthuthukisa ukuqina kodaka, ukumelana nokuqhekeka kanye nokumelana namanzi.
Ukwengeza i-polymer powder kungathuthukisa ukungagxili, ukuqina, ukumelana nokuqhekeka kanye nokumelana nomthelela kodaka nokhonkolo. Ukusebenza kwe-latex powder e-redispersible kuzinzile, futhi kunomphumela omuhle ekuthuthukiseni amandla okubopha odaka, ukuthuthukisa ukuqina kwawo, ukukhubazeka, ukumelana nokuqhekeka nokungafinyeleli. Ukwengeza i-hydrophobic latex powder nakho kunganciphisa kakhulu ukumuncwa kwamanzi kodaka (ngenxa ye-hydrophobicity yalo), kwenze udaka luphefumule futhi lungangenwa amanzi, luthuthukise ukumelana nesimo sezulu, futhi luthuthukise ukuqina kwalo.
Uma kuqhathaniswa nokuthuthukisa amandla aguquguqukayo namandla okubopha kodaka nokunciphisa ukuqina kwawo, umphumela we-latex powder ohlakazeka kabusha ekuthuthukiseni ukugcinwa kwamanzi nokuhlangana kodaka ulinganiselwe. Njengoba ukungezwa kwempushana ye-latex ehlakazeka kabusha kungahlakazeka futhi kubangele inani elikhulu lokungena komoya engxubeni yodaka, umphumela wawo wokunciphisa amanzi usobala kakhulu. Yiqiniso, ngenxa yesakhiwo esimpofu samabhamuza omoya owethulwe, umphumela wokunciphisa amanzi awuzange uthuthukise amandla. Ngokuphambene nalokho, amandla odaka azokwehla kancane kancane ngokwanda kokuqukethwe kwempushana ye-latex ehlakazeka kabusha. Ngakho-ke, ekuthuthukisweni kwamanye ama-mortars adinga ukucabangela amandla okucindezela nokuguquguquka, ngokuvamile kuyadingeka ukwengeza i-defoamer ngesikhathi esifanayo ukuze kuncishiswe umthelela omubi we-latex powder emandleni okucindezela kanye namandla aguquguqukayo odaka. .
