I-emulsion powder enokuchithwa kwakhonaisetyenziswa ikakhulu kwi: yangaphakathi nangaphandle eludongeni putty umgubo, ithayile binder, i-agent edibeneyo yethayile, i-arhente yojongano lomgubo owomileyo, udaka lwangaphandle lokugquma eludongeni, udaka lokuzilinganisa, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi lwangaphandle lodaka lomxube owomileyo.Injongo yodaka kukuphucula ubuthathaka bodaka lwesamente lwesintu olufana nokuqhekeka kunye nemodyuli enwebekayo ephezulu, kunye nokubonelela ngodaka lwesamente olunoguquguquka olungcono kunye nokomelela kokuqina kwebhondi ukuxhathisa kunye nokulibazisa ukwakheka kweentanda kwisamente yodaka.Ngenxa yokwakhiwa kwenethiwekhi edibeneyo phakathi kwepolymer kunye nodaka, ifilimu yepolymer eqhubekayo yenziwa kwiipores ukuqinisa ukudibanisa phakathi kwee-aggregates.Ezinye iipores kumdaka zivaliwe, ngoko ke ukusebenza kodaka olulungisiweyo emva kokuqina kuphuculwe kakhulu kunodaka lwesamente.
Indima yei-emulsion powder efumanekayo kwakhonaeludaka:
1. Phucula amandla acinezelayo kunye namandla asongayo odaka.
2. Ukongezwa kwe latex powderiphucula ubude bodaka, ngaloo ndlela iphucula ukuqina kwempembelelo yodaka, kwaye ikwanika udaka isiphumo esihle sokusasazeka koxinzelelo.
3. Ukuphucula ukunamathela kodaka.Indlela yokudibanisa ixhomekeke kwi-adsorption kunye nokusasazwa kwee-macromolecules kwindawo encangathi, ngelixaumgubo werabhaine-permeability ethile, kunye ne-ether cellulose kunye ingena ngokupheleleyo kumphezulu wezinto ezisisiseko, ukwenzela ukuba ukusebenza komphezulu wesiseko kunye ne-plaster entsha isondele, ngaloo ndlela iphucula i-adsorption kunye nokwandisa kakhulu ukusebenza kwayo.
4. Ukunciphisa i-modulus elastic of mortar, ukuphucula umthamo we-deformation, ukunciphisa i-crack phenomenon.
5. Ukuphucula ukugquma kodaka.Ukuphuculwa kokumelana nokunxiba kubangelwa ikakhulu kubukho bomthamo othile werabha egobileyo kumphezulu wodaka,umgubo oncamathelayoidlala indima yokudibanisa, kunye nesakhiwo se-retinal esakhiwe ngumgubo wokunamathela unokudlula kwimingxuma kunye nokuqhekeka kwi-samente yodaka.Ukubambelela phakathi kwezinto ezisisiseko kunye nemveliso ye-cement hydration iphuculwe, kwaye ukuchasana kokunxiba kuphuculwe.
6. Nika udaka olugqwesileyo ukumelana ne-alkaline.
