Redispersible emulsion podainonyanya kushandiswa mu: mukati nekunze kwemadziro putty poda, tile binder, tile joint agent, yakaoma poda interface agent, yekunze madziro ekudzivirira dhaka, self-leveling dhaka, kugadzirisa dhaka, dhaka rekushongedza, dhaka risina mvura rekunze rinomisa musanganiswa wakaoma.Chinangwa chedhaka ndechekuvandudza kusasimba kwechinyakare simende dhaka senge brittleness uye yakakwira elastic modulus, uye kupa simende dhaka nekushanduka kuri nani uye kusimba kwechisungo kusimba kuramba uye kunonoka kuumbwa kwekutsemuka mudhaka sesimende.Nekuda kweiyo interpenetrating network chimiro pakati pepolymer nedhaka, inoenderera yepolymer firimu inoumbwa mumapores kusimbisa chisungo pakati pezviunganidzwa.Mamwe mapores ari mumatope akavharwa, saka kushanda kwevhu rakagadziridzwa mushure mekuoma kunovandudzwa zvikuru kupfuura yesamende dhaka.
Basa reredispersible emulsion powdermudhaka:
1. Kuvandudza simba rekumanikidza uye kupeta simba redhaka.
2. Kuwedzerwa kwe latex powderinonatsiridza kureba kwedhaka, nekudaro inovandudza kuoma kwemarara, uye zvakare inopa dhaka yakanaka yekuparadzira kushushikana.
3. Kuvandudza kunamatira kwedhaka.Iyo yekubatanidza nzira inotsamira pane adsorption uye kupararira kwe macromolecules pane inonamira pamusoro, neporubber powderine imwe permeability, uye cellulose ether pamwe chete inopinda zvizere pamusoro pezvinhu zvepasi, kuitira kuti kushanda kwepamusoro kwechigadziko uye purasita itsva iri pedyo, nokudaro kuvandudza adsorption uye kuwedzera zvakanyanya kushanda kwayo.
4. Deredza elastic modulus yedhaka, kuvandudza deformation simba, kuderedza kuputika chiitiko.
5. Kuvandudza kusamira kwekupfeka kwedhaka.Kuvandudzwa kwekuramba kupfeka kunonyanya kukonzerwa nekuvapo kweimwe huwandu hwerabha yakakombama pamusoro pevhu, iyoadhesive powderinobata basa rekubatanidza, uye chimiro che retinal chinoumbwa nehupfu hwekunamatira hunogona kupfuura nemakomba uye kuputika mumatope esimende.Iyo yekunamatira pakati peiyo base zvinhu uye simende hydration chigadzirwa inovandudzwa, uye kupfeka kuramba kunovandudzwa.
6. Ipa dhaka zvakanakisa kupikisa alkaline.
