Redispersible polymer poda (RDP) ipolymer ine hupfu inoshandiswa zvakanyanya muindasitiri yekuvaka kuvandudza zvivakwa zvedhaka uye zvimwe simende zvinhu.Kana yawedzerwa kumusanganiswa wedhaka, RDP inobatsira kugadzira kubatana kwakasimba kunowedzera kuomarara kwechinhu, kusimba uye kuramba kune mamiriro ekunze, kuputika uye kurwisa kwemakemikari.Ichi chinyorwa chichatarisa pane zvakanaka mhedzisiro yeRDP pamatope akaomeswa, kusanganisira kugona kwayo kuwedzera simba, kuwedzera kusungirirana, kuvandudza kushanda, uye kuderedza shrinkage.
kuwedzera simba
Imwe yemabhenefiti makuru eRDP pamusoro pedhaka rakaomeswa kugona kwayo kuwedzera simba rezvinhu.Izvi zvinowanikwa nekuvandudza hydration uye kurapa kwemasimende zvimedu, zvichikonzera denser uye denser zvinhu.Iwo mapolymers muRDP anoita seanosungira, achizadza maburi pakati pemasimende uye kugadzira chisungo chakasimba.Mhedzisiro yacho idhaka rine yakakwira compressive uye kusimba simba, zvichiita kuti irambe ichiramba kushushikana, kukanganisa uye deformation.
kuwedzera kunamatira
Imwe mhedzisiro yakanaka yeRDP pane yakaomeswa dhaka kugona kwayo kuwedzera chisungo.RDP inoshanda senge bhiriji mumiriri pakati pemasimende masimende uye substrate pamusoro, ichivandudza kunamatira pakati pezvinhu zviviri izvi.Izvi zvinonyanya kukosha mumashandisirwo akadai se tile, apo dhaka inoda kunamatira kune substrate uye pamusoro petairi.RDP inovimbisa chisungo chakasimba uye chinogara kwenguva refu chinogona kumira kushushikana uye kuomarara kwekushandiswa kwemazuva ese.
Vandudza kushanda
RDP zvakare inovandudza kushanda kwedhaka, zvichiita kuti zvive nyore kusanganisa, kuisa uye kupedza.Iwo mapolymers muRDP anoita semafuta, achidzikisa kupokana pakati pemasimende kuti akwanise kufamba akasununguka.Izvi zvinoita kuti dhaka riwedzere kuyerera uye rive nyore kushanda naro, zvichikonzera kuvakwa kwakapfava uye kuvharika kwakafara.Mhedzisiro yacho chinhu chine zvimiro zvinopindirana uye nyore kushandisa pamusoro pehuwandu hwakawanda hwemamiriro.
kuderedza shrinkage
Rimwe rematambudziko nekushanda nedhaka nderekuti rinoita kuderera kana richioma uye richipora.Shrinkage inogona kukonzera kutsemuka kuumbwa muzvinhu, kukanganisa kugadzikana kwayo uye kusimba.RDP inogona kubatsira kuderedza shrinkage nekudzora kuomesa uye kurapa maitiro echinhu.Iwo mapolymers muRDP anoumba firimu rakatenderedza masimende masimende anoita sechipingamupinyi pakurasikirwa kwemwando.Izvi zvinoderedza kuomeswa uye zvinobvumira mvura kuti iparadzirwe zviri nani mukati mezvinhu zvose, kuderedza mukana wekuderera uye kuputika.
mukupedzisa
Mhedzisiro yakanaka yeRDP padhaka yakaoma yakawanda uye yakakosha.Kana yawedzerwa kumasanganiswa edhaka, RDP inowedzera simba, inowedzera zvisungo, inovandudza kushanda uye inoderedza shrinkage.Aya mabhenefiti anoita RDP chishandiso chakakosha chevashandi vekuvaka vanoda kuvaka zvemhando yepamusoro, zvinogara uye zvinogara kwenguva refu zvivakwa uye zvivakwa.Sezvo indasitiri yekuvaka iri kuramba ichishanduka uye zvinhu zvitsva uye matekinoroji zvichibuda, RDP icharamba iri chikamu chakakosha chevaki nemakondirakiti pasirese.
