Iyo redispersible polymer powder RDP inogona kukurumidza kuparadzirwa mu emulsion mushure mekusangana nemvura, uye ine zvinhu zvakafanana nekutanga emulsion, kureva kuti, firimu inogona kuumbwa mushure mokunge mvura yapera. Iyi firimu ine yakakwira kuchinjika, yakakwira mamiriro ekunze uye kuramba kune akasiyana-siyana Kunamatira kune akasiyana substrates. Pamusoro pezvo, iyo latex poda ine hydrophobicity inogona kuita kuti dhaka rive nekudzivirira kwakanaka kwemvura.
Redispersible polymer poda inonyanya kushandiswa mu:
Yemukati uye yekunze madziro putty poda, tile inonamira, tile grout, yakaoma poda interface mumiriri, yekunze madziro ekunze yekupisa dhaka, dhaka rinozvimisa, dhaka rekugadzirisa, dhaka rekushongedza, dhaka risina mvura uye kunze kwekupisa kwekushisa kwakasanganiswa dhaka. Mudhaka, ndeye kuvandudza kusasimba kwechinyakare simende dhaka senge brittleness uye yakakwirira elastic modulus, uye kupa simende dhaka zviri nani kuchinjika uye kusimba kwechisungo kusimba kuramba uye kunonoka kugadzirwa kwedhaka resimende. Sezvo iyo polymer uye dhaka zvichiumba inopindirana network chimiro, inoenderera polymer firimu inoumbwa mumapores, iyo inosimbisa chisungo pakati peaggregates uye inovhara mamwe mapores mudhaka. Naizvozvo, dhaka rakagadziridzwa mushure mekuomeswa rine kuita kuri nani pane simende dhaka. Kuvandudza kukuru.
Basa redhispersible polymer poda mudhaka rinonyanya mune zvinotevera zvinhu:
1 Kuvandudza simba rekumanikidza uye kushanduka kwesimba redhaka.
2 Kuwedzerwa kwelatex powder kunowedzera kurebesa kwedhaka, nekudaro kunatsiridza kukanganisa kuoma kwedhaka, uye panguva imwe chete kupa dhaka rakanaka rekuparadzira kushushikana.
3 Kuvandudza kusungirirwa kwedhaka. Iyo yekubatanidza nzira inotsamira pane adsorption uye kupararira kwema macromolecules pane inonamira pamusoro. Panguva imwecheteyo, hupfu hwerabha hune humwe hupimo uye hunopinda zvakakwana pamusoro pezvinhu zvepasi pamwe chete ne cellulose ether, kuitira kuti nzvimbo dzepamusoro dzechigadziko uye purasita itsva zvive pedyo, nokudaro zvichivandudza kushanda kwechigadziko. . Adsorption, kuita kwayo kunowedzera zvakanyanya.
4 Deredza iyo elastic modulus yedhaka, kuvandudza kugona kwe deformation, uye kuderedza kupaza chiitiko.
5 Kuvandudza abrasion resistance yedhaka. Kuvandudzwa kwekupokana kwekupfeka kunonyanya kukonzerwa nekuvapo kweimwe nhamba yerabha ridge pamusoro pedhaka, iyo poda yerabha inoita basa rekubatanidza, uye mesh chimiro chakaumbwa nehupfu yerabha inogona kupfuura nemakomba uye kuputika mukati. dhaka resimende. Inovandudza kunamatira kwebinder kune simenti hydration chigadzirwa, nekudaro ichiwedzera kupfeka kuramba.
6 Ipa dhaka zvakanakisa alkali kuramba.
7 Kuvandudza kubatana kweiyo putty, yakanakisa kuramba, alkali kuramba, abrasion kuramba, uye kuwedzera simba rekushanduka.
8. Kuvandudza kusapinda kwemvura uye kupera kweputty.
9 Kuvandudza kuchengetwa kwemvura kweputty, wedzera nguva yakavhurika, uye gadzirisa kushanda.
10 Kuvandudza maitiro ekupikisa kweiyo putty uye kuwedzera kusimba kweiyo putty.
Redispersible latex poda inogadzirwa nepolymer emulsion nekupfapfaidza kuomesa. Mushure mekusanganiswa nemvura mudhaka, inoiswa emulsified uye yakaparadzirwa mumvura kuti iite yakagadzikana polymer emulsion. Mushure mezve redispersible latex poda yaiswa emulsified uye yakaparadzirwa mumvura, mvura inoputika. Iyo firimu yepolymer inoumbwa mudhaka kuti ivandudze zvinhu zvedhaka. Akasiyana redispersible polymer hupfu ane akasiyana mhedzisiro pane yakaoma poda dhaka.
Chigadzirwa zvimiro zve dispersible polymer poda
──Kuvandudza simba rekuchinja uye kushanduka kwesimba redhaka
Iyo firimu repolymer rakagadzirwa naZhaojia dispersible polymer poda ine yakanaka kuchinjika. Firimu rinoumbwa mumikaha uye pamusoro pemasimende edhaka zvidimbu kuti zvigadzire kubatana kunoshanduka. Heavy uye brittle simende dhaka inova elastic. Iyo dhaka inowedzerwa nehupfu inorasika yepolymer yakakwira kakawanda mukutsiga uye kuchinjika kuramba pane dhaka rakajairwa.
── Kuvandudza simba rekunamatira uye kubatana kwedhaka
Iyo redispersible polymer poda se organic binder inogona kugadzira firimu rine simba rakanyanya kusimba uye bond simba pane akasiyana substrates. Inoita basa rakakosha mukunamatira pakati pedhaka uye organic zvinhu (EPS, extruded foam board) uye substrates ine yakatsetseka. Iyo firimu-inogadzira polima poda inogoverwa mukati medhaka system sechinhu chinosimbisa kuwedzera kubatanidzwa kwedhaka.
──Kuvandudza kupikisa kwemaitiro, kusimba uye kupfeka kusagadzikana kwedhaka
Iyo rubber poda zvimedu zvinozadza mhango yedhaka, kuwanda kwedhaka kunowedzera, uye kuramba kwekupfeka kunovandudzwa. Pasi pekuita kwesimba rekunze, ichazorora pasina kukuvadzwa. Iyo polymer firimu inogona kuvapo zvachose mumatope system.
──Kuvandudza kupikisa kwemamiriro ekunze uye kuomesa-kunyunguduka kwedhaka uye kudzivirira dhaka kubva pakutsemuka.
Redispersible latex powder is thermoplastic resin ine yakanaka kuchinjika, iyo inogona kuita kuti dhaka ripindure kune shanduko mune yekunze inopisa uye inotonhora nharaunda, uye zvinobudirira kudzivirira dhaka kubva pakutsemuka nekuda kwekushanduka kwekusiyana kwekushisa.
── Kuvandudza kudzoreredza kwemvura kwedhaka uye kuderedza chiyero chekunwa kwemvura.
Iyo redispersible latex poda inoumba firimu mumhango uye pamusoro pedhaka, uye iyo polymer firimu haizoparadzwi kaviri mushure mekusangana nemvura, iyo inodzivirira kupindira kwemvura uye inovandudza kusamira. Special dispersible polymer powder ine hydrophobic effect, nani hydrophobic effect.
── Kuvandudza kushanda kwekuvaka dhaka &
Iyo polymer rubber powder ine lubricating effect pakati pezvimedu, kuitira kuti zvikamu zvedhaka zvikwanise kuyerera zvakasununguka. Panguva imwecheteyo, rubber powder ine inductive effect pamhepo, ichipa dhaka rekugadzirisa uye kuvandudza kuvaka uye kushanda kwedhaka.
Kushandiswa kwechigadzirwa che dispersible polymer poda
