Kodi Redispersible Polymer Powders ndi chiyani?

Redispersible polima ufa (RDP) ndi mtundu wa ufa wa polima womwe ukhoza kutulutsidwanso m'madzi kuti ukhale wobalalika wokhazikika kapena emulsion.Ndi ufa wouma womwe umapangidwa ndi kupopera-kuyanika emulsion ya polima.RDP imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zomanga, zomatira, zokutira, ndi zosindikizira.

RDP imapangidwa ndi ma polima osiyanasiyana, monga acrylics, polyvinyl acetate (PVA), polyvinyl alcohol (PVOH), ndi styrene-butadiene (SBR).Ma polima nthawi zambiri amasakanizidwa kuti apange ufa wokhala ndi zomwe mukufuna.Kenako ufawo umawumitsidwa kuti ukhale ufa wouma.Ufa ukhoza kutulutsidwanso m'madzi kuti ukhale wobalalika wokhazikika kapena emulsion.

RDP imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zomanga, zomatira, zokutira, ndi zosindikizira.Pomanga, RDP imagwiritsidwa ntchito ngati chowonjezera mumatope opangidwa ndi simenti ndi pulasitala.Imawongolera magwiridwe antchito, kumamatira, komanso kukana madzi kwa matope kapena pulasitala.Mu zomatira, RDP imagwiritsidwa ntchito kukonza zomatira ku gawo lapansi.Mu zokutira, RDP imagwiritsidwa ntchito kupititsa patsogolo kukana kwamadzi komanso kusinthasintha kwa zokutira.Mu zosindikizira, RDP imagwiritsidwa ntchito kupititsa patsogolo kumamatira ndi kusinthasintha kwa sealant.

RDP imagwiritsidwanso ntchito pazinthu zina zosiyanasiyana, monga zokutira zamapepala, zokutira zachikopa, ndi zokutira nsalu.Popaka mapepala, RDP imagwiritsidwa ntchito kupititsa patsogolo kukana kwamadzi ndi mphamvu ya pepala.Pazovala zachikopa, RDP imagwiritsidwa ntchito kupititsa patsogolo kukana kwamadzi komanso kusinthasintha kwachikopa.Mu zokutira nsalu, RDP imagwiritsidwa ntchito kupititsa patsogolo kukana kwa madzi ndi kusinthasintha kwa nsalu.

RDP ndi chida chosunthika chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana.Ndi ufa wowuma umene ukhoza kubwezeretsedwanso m'madzi kuti ukhale wobalalika wokhazikika kapena emulsion.RDP imagwiritsidwa ntchito pomanga, zomatira, zokutira, ndi zosindikizira kuti zitheke kugwira ntchito, kumamatira, komanso kukana madzi kwazinthuzo.RDP imagwiritsidwanso ntchito pazinthu zina zosiyanasiyana, monga zokutira zamapepala, zokutira zachikopa, ndi zokutira nsalu.
