Redispersible polymer poda (RDP) ipolymer inoshandiswa sekuwedzera mune yakaoma musanganiswa dhaka.RDP ihupfu inogadzirwa nekupfapfaidza kuomesa emulsion yepolymer.Kana RDP yawedzerwa kumvura inoumba emulsion yakagadzikana iyo inogona kushandiswa kugadzira dhaka.RDP ine zvivakwa zvakawanda zvinoita kuti ive yakakosha yekuwedzera mune yakaoma-musanganiswa madhaka.Zvinhu izvi zvinosanganisira:
Kuchengetwa kwemvura: RDP inobatsira kuchengetedza mvura mudhaka, nekudaro inovandudza kushanda kwedhaka uye kuderedza huwandu hwemvura inodiwa.
Adhesion: RDP inogona kuvandudza kunamatira pakati pevhu uye substrate, nekudaro ichivandudza kusimba uye kusimba kwedhaka.
Kushanda: RDP inogona kuvandudza kunaka kwechigadzirwa chakapedzwa nekuita kuti dhaka rive nyore kugadzirisa.
Kugara kwenguva refu: RDP inogona kuwedzera kusimba kwedhaka, ichiita kuti irambe ichipokana nekutsemuka uye mamiriro ekunze.
RDP ndeye multifunctional additive iyo inogona kushandiswa mumhando dzakasiyana dzakaoma musanganiswa dhaka.Iyo inonyanya kukodzera matope anoshandiswa kunze kwekushandisa senge stucco uye mataira anonamatira.RDP inogona zvakare kushandiswa mumatope anoshandiswa mukati mekushandisa senge majoini mafirita uye ekugadzirisa makomisheni.
Heano mamwe mabhenefiti ekushandisa RDP mune yakaoma musanganiswa dhaka:
Kuvandudza kuchengetedza kwemvura
Kuvandudza kunamatira
Vandudza kushanda
kuwedzera kusimba
kuderedza kuputika
kuderedza kukuvadzwa kwemvura
kuwedzera kushanduka
Kuvandudza kusamira kwemamiriro ekunze
RDP ndeye yakachengeteka uye inoshanda yekuwedzera iyo inogona kushandiswa kuvandudza mashandiro eiyo yakaoma musanganiswa dhaka.Icho chishandiso chakakosha kune makondirakiti uye vavaki vanoda kugadzira dhaka rinogara, remhando yepamusoro.
Heano mamwe emhando dzakajairika dzeRDP dzinoshandiswa mune yakaoma musanganiswa dhaka:
Vinyl Acetate Ethylene (VAE): VAE RDP ndiyo inowanzozivikanwa yeRDP.Iri sarudzo inosiyana-siyana uye inodhura-inoshanda inogona kushandiswa mumhando dzakasiyana dzematokari.
Styrene Butadiene Acrylate (SBR): SBR RDP isarudzo inodhura kupfuura VAE RDP, asi inopa kuchengetwa kwemvura kuri nani uye kunamatira.
Polyurethane (PU): PU RDP ndiyo inonyanya kudhura mhando yeRDP, asi ine yakanyanya kunaka kuchengetedza mvura, kunamatira uye kusimba.
