Ufa wa Redispersible Polymer (RDP) ndi polima yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana. RDP ndi ufa wosungunuka m'madzi wopangidwa kuchokera ku ma polima osiyanasiyana, kuphatikizapo vinyl acetate, vinyl acetate ethylene, ndi ma acrylic resins. Ufawo umasakanizidwa ndi madzi ndi zina zowonjezera kuti apange slurry, yomwe kenako imagwiritsidwa ntchito kuzinthu zosiyanasiyana. Pali mitundu ingapo ya RDP, iliyonse ili ndi makhalidwe ake apadera komanso ntchito zake. M'nkhaniyi, tifufuza mitundu ina yodziwika bwino ya RDP ndi ntchito zake.
1. Polima wothira vinilu acetate wothiranso
Ma polima osungunuka a vinyl acetate ndi omwe amapezeka kwambiri mu RDP. Amapangidwa kuchokera ku vinyl acetate ndi vinyl acetate ethylene copolymer. Tinthu ta polymer timafalikira m'madzi ndipo timatha kusinthidwa kukhala madzi. Mtundu uwu wa RDP uli ndi ntchito zosiyanasiyana kuphatikizapo mortars wouma, zinthu za simenti ndi mankhwala odzipangira okha. Amapereka kumatira kwabwino, kusinthasintha komanso kulimba.
2. Polima wosungunuka wa acrylic
Ma polima osungunuka a acrylic amapangidwa kuchokera ku ma copolymer a acrylic kapena methacrylic. Mphamvu zawo zapadera komanso kukana kukwawa zimapangitsa kuti zikhale zabwino kwambiri pakugwiritsa ntchito komwe kulimba ndikofunikira. Amagwiritsidwa ntchito mu zomatira za matailosi, zoteteza kunja ndi makina omalizitsa (EIFS), komanso zokonzera ma mortar.
3. Ethylene-vinyl acetate polima yotha kusungunukanso
Ma polima osinthika a ethylene-vinyl acetate amapangidwa kuchokera ku ethylene-vinyl acetate copolymers. Amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo simenti, ma grout ndi zomatira za matailosi. Ali ndi kusinthasintha kwabwino komanso kumamatira kuti agwiritsidwe ntchito m'malo ovuta kwambiri.
4. Polima wothiranso wa Styrene-butadiene
Ma polima osungunuka a styrene-butadiene amapangidwa kuchokera ku ma copolymer a styrene-butadiene. Amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo kukonza konkriti, zomatira za matailosi ndi ma grout. Ali ndi mphamvu zabwino zoteteza madzi komanso zomatira.
5. Ufa wa polima wobwezeretsedwanso
Ufa wa polima wopangidwa kuti ukhale wothiranso madzi ndi RDP wopangidwa kuti ukhale wothiranso madzi ukauma. Umagwiritsidwa ntchito nthawi zambiri pamene chinthucho chimakumana ndi madzi kapena chinyezi chikagwiritsidwa ntchito. Izi zikuphatikizapo zomatira za matailosi, grout, ndi caulk. Zimakhala ndi kukana madzi komanso kusinthasintha kwabwino.
6. Ufa wa polima wothira madzi womwe umasungunukanso
Ufa wa polima wothira madzi womwe umasungunukanso ndi madzi womwe umapangidwa kuti uwonjezere kukana madzi kwa zinthu zopangidwa ndi simenti. Nthawi zambiri umagwiritsidwa ntchito pamene chinthucho chimakhudzana ndi madzi, monga Exterior Insulation and Finishing Systems (EIFS), zomatira za matailosi a dziwe losambira ndi zomangira zokonzera konkire. Uli ndi kukana madzi komanso kulimba.
Ufa wa latex wosungunukanso ndi chinthu chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chingagwiritsidwe ntchito m'njira zosiyanasiyana. Pali mitundu ingapo ya RDP, iliyonse ili ndi mawonekedwe ake apadera komanso ntchito zake. Kumamatira kwawo kwabwino, kusinthasintha komanso kulimba kumapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana. Zikagwiritsidwa ntchito moyenera, zingathandize kukonza ubwino ndi moyo wautali wa zinthu zambiri zomangira.
