Redispersible polymer poda (RPP) chinhu chakajairika chekuwedzera chinoshandiswa mune yakaoma dhaka zvigadzirwa.Ihwo hupfu hunoyerera husingabhadharwi hunogadzirwa nekupfapfaidza-kuomesa emulsion yepolymer.Kana yawedzerwa kune yakaoma dhaka musanganiswa, inovandudza kunamatira, kushanduka, kushanda, uye kusimba.
Heano mamwe mashandisirwo eRPP mune akasiyana dhaka zvigadzirwa:
- Tile adhesives: RPP inowanzoshandiswa mumatairi adhesives kuvandudza kunamatira, kuderedza kunyura kwemvura, uye kuwedzera kushanduka.Inobatsira kunamatira kusungira zvakasimba kune substrate uye kune tile.Pamusoro pezvo, inopa yakanakisa kudzivirira kwemvura, iyo yakakosha munzvimbo dzakanyorova senge yekugezera uye kicheni.
- Exterior insulation and finishing systems (EIFS): EIFS imhando ye cladding system inoshandiswa kuvandudza simba rekushandisa kwezvivakwa.RPP inoshandiswa muEIFS kuvandudza kunamatira pakati peiyo insulation zvinhu uye substrate.Inovandudzawo kushanda kwedhaka uye inoderedza shrinkage.
- Self-leveling makomisheni: RPP inoshandiswa mu-self-leveling makomisheni kuvandudza kuyerera uye kuyera zvivakwa zvedhaka.Iyo inopawo yakanakisa kunamatira kune substrate uye inoderedza shrinkage.Komisheni yekuzvimisa-yega inowanzoshandiswa kuyera pasi kongiri usati waisa kupera kwepasi.
- Kugadzirisa madhaka: RPP inoshandiswa mukugadzirisa madhaka kuvandudza kunamatira pakati pekugadzirisa dhaka uye substrate.Inovandudzawo kushanda kwedhaka uye inoderedza shrinkage.Kugadzirisa marata anowanzo shandiswa kugadzirisa nzvimbo dzekongiri dzakakuvadzwa nekuda kwekutsemuka kana kuparara.
- Grouts: RPP inoshandiswa mumagrouts kuvandudza kunamatira pakati pegrout nematairi.Inopawo yakanakisa kudzivirira kwemvura, iyo yakakosha munzvimbo dzakanyorova senge yekugezera uye makicheni.Grouts anowanzoshandiswa kuzadza mapeji pakati pematairi mushure mekunge aiswa.
Pakazere, kushandiswa kweRPP mune yakaoma dhaka zvigadzirwa kune akawanda mabhenefiti uye kunogona kubatsira kuvandudza mashandiro uye kusimba kwedhaka.
