Ndezvipi zvimiro zvedhaka zvinogona kuvandudzwa ne redispersible latex poda?

Redispersible latex poda inogadzirwa nepolymer emulsion nekupfapfaidza kuomeswa, yakavhenganiswa nemvura mune simende dhaka, emulsified uye yakaparadzirwa mumvura, uyezve regenerates yakagadzikana polymer emulsion. Mushure mekugadzirisazve latex poda yakasvibiswa uye yakaparadzirwa mumvura, mvura inoputika, Gadzira firimu repolymer mudhaka kuti uvandudze zvinhu zvedhaka. Yakasiyana redispersible latex poda ine mhedzisiro yakasiyana pane yakaoma poda dhaka.

1. Kuvandudza kupikisa kwemaitiro, kuita uye kupfeka kusagadzikana kwedhaka

Iyo dhaka yakazadzwa nesamende dhaka pore cavity, iyo compactness yesamende dhaka inovandudzwa, uye kupfeka kuramba kunovandudzwa. Pasi pekuita kwesimba rekunze, inogona kukonzera kuzorora pasina kuparadzwa. Polymer bepa rinogona kuchengetwa mune simende mortar management system.

2. Kuvandudza kunamatira kwekuvakwa kwedhaka

Iyo polymer poda particles ine wetting effect, kuitira kuti zvikamu zviviri zvesamende dhaka zvinogona kuyerera zvakasununguka. Mukuwedzera, iyo poda yerabha ine mhedzisiro yekupinza gasi.

3. Kuvandudza chisungo chinomanikidzira simba uye simba rakabatana rematope

Seyakagadzika kemikari inonamira, redispersible latex poda inogona kuburitsa yakakwira yekumanikidza simba uye inomanikidza simba pamabhodhi akasiyana. Inobata basa rakakosha mukubatanidzwa kwesamende dhaka uye organic makemikari mbishi zvinhu (mudumbu, extruded insulating foam board) uye pamusoro pebhodhi rekuchenesa. DEM raw materials uye depilatory polymer poda inoshandiswa zvakanyanya mune ese simende dhaka manejimendi masisitimu kuvandudza kubatana kwesamende dhaka.

4. Kuvandudza kuchembera kwedhaka, dzivisa kutonhora-kunyunguduka, uye kudzivirira dhaka resimende kubva pakutsemuka.

Redispersible latex powder is thermoplastic resin ine yakanaka kuchinjika, iyo inogona kuita kuti dhaka riite nekukuvadzwa kunokonzerwa nekupisa kwekunze uye kutonhora nharaunda, uye zvine musoro kudzivirira kuputika mudhaka nekuda kwekushanduka kwekushisa.

5. Wedzerai hydrophobicity yedhaka uye kuderedza hunyoro

Iyo redispersible latex poda yakasvibiswa mune simende yevhu dhaka uye pamusoro pedenga, uye pepa repolymer harisi nyore kupatsanurwa zvakare mushure mekugadziriswa kwemvura, kuvharira kupindira kwemvura nekuvandudza kusapinda. Iri girazi regirazi rinodzivirira mvura rine mhedzisiro iri nani nekuda kwekugona kwayo kwakasiyana kuparadzira zvisikwa latex poda.

Iko kushandiswa kukuru kwe redispersible latex powder

Yemukati nekunze madziro putty poda, tile inonamira, tile inonongedza agent, yakaoma poda interface mumiriri, yekunze yekupisa yekuvharisa dhaka yekunze kwemadziro, inozvimisa-leveling dhaka, kugadzirisa dhaka, dhaka rekushongedza, dhaka risina mvura kunze kwekupisa kwekupisa kwakaoma-musanganiswa dhaka. Mudhaka, ndeye kuvandudza brittleness, yakakwira elastic modulus uye kumwe kusasimba kwechinyakare simende dhaka, uye kupa dhaka resimende nekushanduka kuri nani uye kusimba kwechisungo chesimba, kuitira kuramba uye kunonoka chizvarwa chekutsemuka kwesamende. Sezvo iyo polymer uye dhaka zvinoumba interpenetrating network chimiro, inoenderera polymer firimu inoumbwa mumapores, iyo inosimbisa chisungo pakati peaggregates uye inovhara mamwe pores mudhaka, saka yakagadziridzwa dhaka mushure mekuoma iri nani pane simende dhaka. Pane kuvandudzika kukuru.

Chigadzirwa chezvigadzirwa zve redispersible latex poda

1. Kuvandudza simba rekukombama uye kushanduka kwesimba redhaka

Iyo firimu repolymer rakagadzirwa neredispersible latex poda ine yakanaka kuchinjika. Mafirimu anoumbwa mumikaha uye pamusoro pemasimende edhaka zvidimbu kuti aumbe zvinochinjika zvinongedzo. Heavy uye brittle simende dhaka inova elastic. Doka rinowedzerwa neredispersible latex poda rakapetwa kakati wandei mukusimba uye kuchinjika kuramba pane dhaka rakajairwa.

2. Kuvandudza simba rekubatanidza uye kubatana kwedhaka

Mushure meiyo redispersible latex poda senge organic binder yakaumbwa kuita firimu, inogona kuumba yakakwirira kusimba simba uye bonding simba pane akasiyana substrates. Inoita basa rakakosha mukunamira kwedhaka kune organic zvinhu (EPS, extruded foam board) uye yakatsetseka yepasi substrates. Iyo firimu-inogadzira polymer rubber poda inogoverwa mukati medhaka system sechinhu chinosimbisa kuwedzera kubatanidzwa kwedhaka.

3. Kuvandudza kupikisa kwemaitiro, kusimba uye kupfeka kusagadzikana kwedhaka

Iyo rubber poda zvimedu zvinozadza mhango yedhaka, kuwanda kwedhaka kunowedzerwa, uye kuramba kwekupfeka kunovandudzwa. Pasi pekuita kwesimba rekunze, inoburitsa kuzorora pasina kuparadzwa. Iyo polymer firimu inogona kuve iripo zvachose mudhaka system.

4. Kuvandudza kudzivirira 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 ribate nekushanduka kwekunze kutonhora uye kupisa nharaunda, uye zvinobudirira kudzivirira dhaka kubva pakutsemuka nekuda kwekushanduka kwekusiyana kwekushisa.

5. Kuvandudza hydrophobicity yedhaka uye kuderedza kunyura kwemvura

Iyo redispersible latex poda inoumba firimu pamhango uye pamusoro pedhaka, uye iyo polymer firimu haizoparadzi zvakare mushure mekuratidzwa kumvura, iyo inodzivirira kupindira kwemvura uye inovandudza kusamira. Special redispersible latex powder ine hydrophobic effect, nani hydrophobic effect.

6. Kuvandudza kushanda kwekuvaka kwedhaka

Kune mafuta ekuzora pakati pepolymer rubber poda zvimedu, kuitira kuti zvikamu zvedhaka zvikwanise kuyerera zvakazvimirira. Panguva imwecheteyo, rubber powder ine inductive effect pamhepo, ichipa kusungirirwa kwedhaka uye kuvandudza kushanda kwekuvaka kwedhaka.
