Chii chinonzi Redispersible Polymer Powders?

Redispersible polymer powder (RDP) imhando yepolymer powder inogona kuparadzirwa mumvura kuti iite kupararira kwakagadzikana kana emulsion. Ihupfu hwakaoma hunogadzirwa nekupfapfaidza-kuomesa emulsion yepolymer. RDP inoshandiswa mumhando dzakasiyana siyana dzekushandisa, kusanganisira kuvaka, zvinonamira, machira, uye sealants.

RDP inoumbwa neakasiyana mapolymers, akadai se acrylics, polyvinyl acetate (PVA), polyvinyl doro (PVOH), uye styrene-butadiene (SBR). Iwo mapolymers anowanzo kusanganiswa pamwe chete kugadzira poda ine inodiwa zvivakwa. Hupfu hunobva hwapfapfaidzwa kuita hupfu hwakaoma. Iyo hupfu inogona kuparadzirwa zvakare mumvura kuti iite kupararira kwakagadzikana kana emulsion.

RDP inoshandiswa mumhando dzakasiyana siyana dzekushandisa, kusanganisira kuvaka, zvinonamira, machira, uye sealants. Mukuvaka, RDP inoshandiswa sekuwedzera mune simende-based madhaka uye plasters. Inovandudza kushanda, kunamatira, uye kuramba kwemvura kwedhaka kana plaster. Mukunamatira, RDP inoshandiswa kuvandudza kunamatira kwekunamatira kune substrate. Mumachira, RDP inoshandiswa kuvandudza kudzivirira kwemvura uye kushanduka kwejira. Mune zvisimbiso, RDP inoshandiswa kuvandudza kunamatira uye kuchinjika kwechisimbiso.

RDP inoshandiswawo mune akasiyana mamwe maapplication, akadai semapepa ekuputira, ematehwe ematehwe, uye machira machira. Mune mapepa ekuputira, RDP inoshandiswa kuvandudza kudzivirira kwemvura uye simba repepa. Mumachira ematehwe, RDP inoshandiswa kuvandudza kudzivirira kwemvura uye kushanduka kwematehwe. Mumachira machira, RDP inoshandiswa kuvandudza kudzivirira kwemvura uye kuchinjika kwejira.

RDP chinhu chakasiyana-siyana chinoshandiswa mumhando dzakasiyana dzekushandisa. Ihupfu hwakaoma hunogona kuparadzirwa zvakare mumvura kuti huite kupararira kwakagadzikana kana emulsion. RDP inoshandiswa mukuvaka, zvekunamira, machira, uye zvisimbiso kuvandudza kushanda, kunamatira, uye kuramba kwemvura kwechigadzirwa. RDP inoshandiswawo mune akasiyana mamwe maapplication, akadai semapepa ekuputira, ematehwe ematehwe, uye machira machira.
