Redispersible Polymer Powder (RDP) ndi polima wogwiritsidwa ntchito zosiyanasiyana. RDP ndi ufa wosungunuka m'madzi wopangidwa kuchokera ku ma polima osiyanasiyana, kuphatikiza vinyl acetate, vinyl acetate ethylene, ndi acrylic resins. Ufawu umasakanizidwa ndi madzi ndi zina zowonjezera kupanga slurry, zomwe zimagwiritsidwa ntchito ku magawo osiyanasiyana. Pali mitundu ingapo ya RDP, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake. M'nkhaniyi, tiwona mitundu yodziwika bwino ya RDP ndikugwiritsa ntchito kwake.
1. Vinyl acetate redispersible polima
Vinyl acetate redispersible polima ndi mtundu wodziwika kwambiri wa RDP. Amapangidwa kuchokera ku vinyl acetate ndi vinyl acetate ethylene copolymer. The polima particles omwazika m'madzi ndipo akhoza reconstituted mu madzi boma. Mtundu uwu wa RDP uli ndi ntchito zosiyanasiyana kuphatikiza matope osakaniza owuma, zinthu za simenti ndi zodzipangira zokha. Amapereka zomatira zabwino kwambiri, kusinthasintha komanso kukhazikika.
2. Acrylic redispersible polima
Ma polima a Acrylic redispersible amapangidwa kuchokera ku acrylic kapena methacrylic copolymers. Mphamvu zawo zapadera komanso kukana kwa abrasion zimawapangitsa kukhala abwino kwa mapulogalamu omwe kulimba ndikofunikira. Amagwiritsidwa ntchito pomatira matailosi, kutsekereza kwakunja ndi makina omaliza (EIFS), ndi kukonza matope.
3. Ethylene-vinyl acetate redispersible polima
Ma polima a ethylene-vinyl acetate redispersible polima amapangidwa kuchokera ku ethylene-vinyl acetate copolymers. Amagwiritsidwa ntchito pazinthu zosiyanasiyana kuphatikiza matope a simenti, ma grouts ndi zomatira matailosi. Amakhala ndi kusinthasintha kwakukulu komanso kumamatira kuti agwiritsidwe ntchito m'malo opsinjika kwambiri.
4. Styrene-butadiene redispersible polima
Styrene-butadiene redispersible polima amapangidwa kuchokera ku styrene-butadiene copolymers. Amagwiritsidwa ntchito pazinthu zosiyanasiyana kuphatikiza matope okonza konkire, zomatira matailosi ndi ma grouts. Amakhala ndi madzi abwino kwambiri komanso zomatira.
5. Re-emulsifiable polima ufa
Re-emulsifiable polymer powder ndi RDP yokonzedwa kuti ipangidwenso m'madzi pambuyo poyanika. Amagwiritsidwa ntchito pazinthu zambiri zomwe mankhwalawo amawonekera pamadzi kapena chinyezi pambuyo pa ntchito. Izi zikuphatikizapo zomatira matailosi, grout, ndi caulk. Ali ndi kukana kwamadzi kwambiri komanso kusinthasintha.
6. Hydrophobic redispersible polima ufa
Hydrophobic redispersible polima ufa wopangidwa kuti uwonjezere kukana kwamadzi pazinthu zopangidwa ndi simenti. Amagwiritsidwa ntchito m'malo omwe mankhwalawo amakumana ndi madzi, monga Exterior Insulation and Finishing Systems (EIFS), zomatira matailosi a dziwe losambira ndi matope okonza konkire. Ili ndi kukana kwamadzi kwambiri komanso kukhazikika.
Redispersible latex powder ndi zinthu zosunthika zomwe zingagwiritsidwe ntchito pazinthu zambiri. Pali mitundu ingapo ya RDP, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake. Kumamatira kwawo kwabwino, kusinthasintha komanso kulimba kumawapangitsa kukhala abwino kugwiritsidwa ntchito pazinthu zosiyanasiyana. Akagwiritsidwa ntchito moyenera, angathandize kupititsa patsogolo ubwino ndi moyo wautali wazinthu zambiri zomanga.
