Chii chinonzi Redispersible Polymer Powder?

Redispersible polymer hupfu(RPP) inoyerera-inoyerera, chena poda inowanikwa nespray-drying polymer emulsions.Inosanganisira polymer resin particles inoparadzirwa mumvura kuti iite emulsion, iyo inobva yaomeswa kuita fomu yehupfu.RPP ine musanganiswa wemapolymers, kazhinji vinyl acetate ethylene (VAE), vinyl acetate versatate (VAc/VeoVa), acrylics, uye mamwe macopolymers.Aya mapolymer anosarudzwa zvichibva pane zvawo chaiwo zvivakwa uye chinangwa chekushandisa.

Heano mamwe akakosha maitiro uye zvimiro zve redispersible polymer poda:

1. Kugadzira Firimu: Kana yakasanganiswa nemvura, zvimedu zveRPP zvinopararira uye zvinogadzira firimu repolymer rinoshanduka pakuoma.Iyi firimu inopa kunamatira, kubatana, uye kusimba kune akasiyana ma substrates, akadai sekongiri, dhaka, mataira anonamira, uye machira.
2. Adhesion: RPP inowedzera kunamatira pakati pezvinhu zvakasiyana-siyana, zvinosanganisira substrates uye machira, mataira uye zvinonamira, uye fiber uye mabhainda.Inovandudza simba rechisungo uye inodzivirira delamination kana dhizaini yezvinhu nekufamba kwenguva.
3. Flexibility: RPP inopa kuchinjika kune machira, zvinonamira, uye dhaka, zvichivabvumira kugarisa substrate kufamba, kuwedzera kwemafuta, uye zvimwe zvinonetsa pasina kuputika kana kutadza.Ichi chivakwa chakakosha pakuchengetedza kutendeseka kwezvinhu zvakaiswa.
4. Kupokana kweMvura: RPP inovandudza kudzivirira kwemvura kwekuumbwa, ichiita kuti ive yakakodzera nzvimbo dzekunze kana dzakanyorova.Inobatsira kudzivirira kupenya kwemvura uye inodzivirira pasi pe substrates kubva mukukuvadzwa.
5. Kugara kwenguva refu: RPP inowedzera kusimba uye kusimba kwemamiriro ekunze kwezvinhu nekuvandudza kuramba kwavo kune UV mwaranzi, kuratidzwa kwemakemikari, abrasion, uye kuchembera.Iyo inorebesa hupenyu hwemachira, zvinonamira, uye dhaka, ichidzikisa zvinodiwa zvekugadzirisa uye mutengo.
6. Kushanda: RPP inokwidziridza kushanda uye kugadzirisa kwemaitiro nekuvandudza kuyerera, kuyera, uye kupararira.Iyo inovimbisa kufukidzwa kwakafanana, kushandiswa kwakapfava, uye kuenderana kuita kwezvinhu zvakashandiswa.
7. Rheology Kudzora: RPP inoshanda seye rheology modifier, ichipesvedzera viscosity, thixotropy, uye sag kuramba kwemaitiro.Inobatsira kukwirisa zvivakwa zvekushandisa uye kuita kwemajasi, zvinonamira, uye dhaka.
8. Kugarisana: RPP inoenderana nehuwandu hwakawanda hwezvimwe zvinowedzera, mafirita, pigment, uye mabhainda anowanzoshandiswa mukugadzira.Izvo hazvikanganisi zvakashata zvivakwa kana kuita kwezvimwe zvikamu, kuve nechokwadi chekugadzirisa kugadzikana uye kusagadzikana.

Redispersible polymer poda inowana kushandiswa kwakakura mumashandisirwo ekuvaka, anosanganisira anonamira ematairi, simende-based motars, self-leveling makomisheni, kudzivirira mvura membranes, uye kugadzirisa madhaka.Iyo zvakare ine maapplication ekuputira, anonamira, sealants, machira, uye mapepa maindasitiri, achibatsira mukuita uye kusimba kwezvakasiyana zvinhu uye zvigadzirwa.
