Zvimiro zve redispersible latex powder
Redispersible polymer poda ine akati wandei zvimiro zvinoita kuti ive yakakodzera kushandiswa muzvigadzirwa zvepolymer mortar.Chimwe chezvinhu zvakakosha zvehupfu kugona kwavo kuvandudza kunamatira kwechigadzirwa uye kuchinjika.Izvi zvinodaro nekuti hupfu hunoumbwa nemapolymer particles akamiswa mumvura.Apo iyo poda yakasanganiswa nemvura, inoumba emulsion yakagadzikana inogona kushandiswa nyore nyore kune substrate nzvimbo.Sezvo mvura ichiputika, zvidimbu zvepolymer zvinobatana kuti zvigadzire firimu rinoramba richibatanidza chigadzirwa kune substrate.
Chimwe chivako chepolymer powders inorasika ndiko kuramba kwavo kwemvura.Hupfu ndeye hydrophobic, zvinoreva kuti inodzinga mvura.Izvi zvinoita kuti zvigadzirwa zvepolymer dhaka zvirambe zvichidzivirira mvura, zvichizvidzivirira kubva pakutsemuka uye kuipa kana zvasangana nehunyoro.Ichi chivakwa chinoita zvakare kuti zvigadzirwa zvigare zvakasimba sezvo zvichikwanisa kumira kuratidzwa kwenguva refu kumvura.
Redispersible latex poda zvakare ine yakanakisa yekunamatira zvimiro.Inoumba chisungo chakasimba pakati pedhaka uye substrate, inovandudza kushanda kwese kwechigadzirwa.Ichi chivakwa chakanyanya kukosha kune polymer dhaka zvigadzirwa zvekunze kunyorera sezvo ivo vachifanira kukwanisa kumira nemamiriro ekunze akaomarara.
