Redispersible Polima Powder (RDP)ndi chowonjezera chofunikira chomwe chimagwiritsidwa ntchito mumitundu yosiyanasiyana yamatope owuma. Ndi ufa wopangidwa ndi polima womwe, ukasakanizidwa ndi madzi, umagawanso kupanga filimu. Kanemayu amapereka zinthu zingapo zofunika pamatope, monga kumamatira bwino, kusinthasintha, kukana madzi, komanso kukana ming'alu. Pamene zofunikira zomanga zikukula, ma RDP ayamba kugwiritsidwa ntchito kwambiri pazinthu zapadera zamatope owuma, pomwe phindu lawo limakhala ndi gawo lofunikira pakupititsa patsogolo magwiridwe antchito.
1.Redispersible Polima Powder (RDP) Mwachidule
Redispersible Polymer Powder(RDP)s amapangidwa ndi kuyanika ma emulsion a ma polima opangira, omwe nthawi zambiri amakhala styrene-butadiene (SB), vinyl acetate-ethylene (VAE), kapena ma acrylics. Ma polima awa ndi finely milled ndipo amatha kumwazanso akasakaniza ndi madzi, kupanga filimu kuti bwino mawotchi zimatha matope.
Zofunikira zazikulu za RDPs:
Kuwongola kumamatira: Kupititsa patsogolo kulumikizana kwa magawo.
Kusinthasintha: Amapereka malo ogona komanso amachepetsa kusweka.
Kukana madzi: Kumawonjezera kukana kulowa madzi.
Kupititsa patsogolo ntchito: Imawonjezera kumasuka kwa ntchito.

b.Crack Resistance
Kusinthasintha komwe kumaperekedwa ndi RDPs kumalola makina amatope kuti agwirizane ndi kayendedwe ka kutentha, kuchepetsa chiopsezo cha ming'alu. Katunduyu ndi wofunikira pazogwiritsa ntchito zakunja, monga ma pulasitala ndi ETICS, pomwe mayendedwe omanga kapena nyengo yoipa imatha kuyambitsa ming'alu.
c.Kukaniza Madzi
Pazinthu zonse zamkati ndi zakunja, ma RDP amathandizira kuti madzi asasunthike bwino, zomwe zimathandiza kupewa kulowa kwa chinyezi. Izi ndizopindulitsa makamaka m'malo achinyezi, kuwonetsetsa kuti zinthu zomangirazo zimakhala zazitali komanso zolimba.
d.Kupititsa patsogolo Ntchito
Mitondo yomwe ili ndi RDP ndiyosavuta kuyiyika, kufalitsa, ndikusintha, kuwongolera zomwe ogwiritsa ntchito azigwiritsa ntchito. Uwu ndi mwayi waukulu pazitsulo zomatira matailosi ndi matope okonza, komwe kusavuta kugwiritsa ntchito kumatha kufulumizitsa ntchito yomanga.
e.Kukhalitsa
Mitondo yokhala ndi Redispersible Polymer Powder(RDP)s imakhala yosamva kuvala ndi kung'ambika, kuonetsetsa kuti ikugwira ntchito motalika pansi pa zovuta zosiyanasiyana zachilengedwe.
Redispersible Polima Powder (RDP)s ndi zigawo zikuluzikulu pakupanga matope apadera owuma, kupititsa patsogolo mawonekedwe awo akuthupi monga kumamatira, kusinthasintha, kugwira ntchito, ndi kulimba. Kaya amagwiritsidwa ntchito pomatira matailosi, pulasitala, matope okonzera, kapena makina otchingira akunja, ma RDP amawongolera magwiridwe antchito komanso moyo wautali wa chinthucho. Pamene miyezo yomanga ikupitilira kufunafuna zida zapadera, kugwiritsa ntchito ma RDPs mumatope owuma kupitilirabe kuchitapo kanthu pokwaniritsa zosowazi.
