Ufa wa Polima Wosungunukanso (RDP)ndi chowonjezera chofunikira chomwe chimagwiritsidwa ntchito popanga mitundu yosiyanasiyana ya matope ouma. Ndi ufa wochokera ku polima womwe, ukasakanizidwa ndi madzi, umagawidwanso kuti upange filimu. Filimuyi imapereka zinthu zingapo zofunika ku matope, monga kumatira bwino, kusinthasintha, kukana madzi, komanso kukana ming'alu. Pamene zofunikira pakupanga zikusintha, ma RDP agwiritsidwa ntchito kwambiri pazinthu zapadera za matope ouma, komwe ubwino wawo umagwira ntchito yofunika kwambiri pakukweza magwiridwe antchito.
1.Ufa wa Polima Wosungunukanso (RDP) Chidule
Ufa wa Polima Wosasinthika (RDP) umapangidwa ndi ma emulsion owuma a ma polima opangidwa, omwe nthawi zambiri amakhala styrene-butadiene (SB), vinyl acetate-ethylene (VAE), kapena acrylics. Ma polima awa amapukutidwa bwino ndipo amatha kusungunukanso akasakanikirana ndi madzi, ndikupanga filimu yomwe imawongolera mphamvu za makina a matope.
Makhalidwe akuluakulu a RDPs:
Kukulitsa kumatira: Zimathandiza kuti zinthu zigwirizane ndi zinthu zapansi panthaka.
Kusinthasintha: Amapereka malo osungira kuyenda komanso amachepetsa ming'alu.
Kukana madzi: Zimawonjezera kukana kulowa kwa madzi.
Kugwira ntchito bwino: Zimathandiza kuti ntchito ikhale yosavuta.
Kulimba kwamphamvu: Zimathandizira kuti ntchito ikhale yogwira ntchito kwa nthawi yayitali m'mikhalidwe yovuta kwambiri.
2.Kugwiritsa Ntchito Mu Zapadera Zopangira Mtondo Wouma
a.Zomatira za Matailosi
Ma glue a matailosi ndi amodzi mwa magwiritsidwe ntchito ofala kwambiri a Redispersible Polymer Powder (RDP). Ma glue awa adapangidwa kuti amangirire matailosi pamalo osiyanasiyana, kuphatikiza makoma ndi pansi. Kuphatikizidwa kwa RDP mu ma glue a matailosi kumawonjezera kwambiri makhalidwe otsatirawa:
Mphamvu ya mgwirizano: Chigwirizano cha guluu pakati pa matailosi ndi substrate chimakula kwambiri, zomwe zimalepheretsa matailosi kusweka pakapita nthawi.
Kusinthasintha: RDP imathandiza kukonza kusinthasintha kwa guluu, zomwe zimathandiza kuti lisamasweke ndi kusweka chifukwa cha kuyenda kwa gawo lapansi kapena matailosi okha.
Nthawi yotsegulira: Nthawi yogwira ntchito isanayambe kukhazikika kwa guluu imakulitsidwa, zomwe zimapangitsa kuti pakhale nthawi yochulukirapo yosinthira panthawi yoyika.

b.Mapulasitala
Ma Redispersible Polymer Powder (RDP) amagwiritsidwa ntchito kwambiri m'mapulasitala amkati ndi akunja kuti akonze kumamatira, kukana madzi, komanso kusinthasintha. Pankhani ya mawonekedwe akunja kapena machitidwe a façade, ma RDP amapereka zabwino zina monga kukana kwambiri ku nyengo ndi kuwonongeka kwa UV.
Kumamatira ku zinthu zapansi: RDP imaonetsetsa kuti pulasitalayo imamatira bwino ku konkire, njerwa, kapena zipangizo zina zomangira, ngakhale ikakumana ndi madzi ndi chinyezi.
Kukana madziMakamaka m'mapulasitala akunja, ma RDP amathandizira kuti madzi asalowe, zomwe zimaletsa kulowa kwa chinyezi komanso kuwonongeka komwe kumachitika chifukwa cha kuzizira ndi kusungunuka.
Kukana ming'alu: Kusinthasintha kwakukulu kwa pulasitala kumachepetsa mwayi wopanga ming'alu chifukwa cha kutentha kapena kupsinjika kwa makina.
| Katundu | Popanda RDP | Ndi RDP |
| Kumamatira ku gawo lapansi | Wocheperako | Zabwino kwambiri |
| Kukana madzi | Zochepa | Pamwamba |
| Kusinthasintha | Zochepa | Kuwonjezeka |
| Kukana ming'alu | Wosauka | Zabwino |
c.Konzani Ma Mota
Ma mortar okonza amagwiritsidwa ntchito kukonza malo owonongeka, monga konkriti wosweka kapena wosweka. Mu ntchito izi, RDP imagwira ntchito yofunika kwambiri pakukonza zotsatirazi:
Kugwirizana ndi malo akale: Ufa wa Redispersible Polymer (RDP) umathandiza kuti zinthu zokonzedwazo zigwirizane bwino ndi zinthu zomwe zilipo, zomwe zimathandiza kuti zinthuzo zigwirizane bwino.
Kugwira ntchito bwino: RDP imapangitsa kuti matopewo azigwiritsidwa ntchito mosavuta komanso molingana, zomwe zimapangitsa kuti kugwiritsa ntchito mosavuta.
KulimbaMwa kuwonjezera mphamvu za mankhwala ndi makina a matope, RDP imatsimikizira kukonzanso kwanthawi yayitali komwe kumalimbana ndi ming'alu, kuchepa, ndi kuwonongeka kwa madzi.
| Katundu | Popanda RDP | Ndi RDP |
| Kugwirizana ndi gawo lapansi | Wocheperako | Zabwino kwambiri |
| Kugwira ntchito bwino | Zovuta | Yosalala komanso yosavuta kugwiritsa ntchito |
| Kulimba | Zochepa | Pamwamba |
| Kukana kuchepa | Wocheperako | Zochepa |
d.Machitidwe Otetezera Kutentha Kwakunja (ETICS)
Mu makina ophatikizira kutentha kwakunja (ETICS), Redispersible Polymer Powder (RDP) amagwiritsidwa ntchito mu guluu kuti amangirire zinthu zotetezera kutentha ku makoma akunja a nyumba. Ma RDP amathandizira kuti dongosolo lonse ligwire ntchito mwa:
Kulimbitsa kumamatira: Zimathandiza kuti pakhale mgwirizano wolimba pakati pa chotenthetsera ndi substrate.
Kukana nyengo: Kusinthasintha kwakukulu komanso kukana madzi kumathandiza kuti dongosololi lizigwira ntchito bwino pakakhala nyengo zosiyanasiyana.
Kukana kugundana: Amachepetsa chiopsezo cha kuwonongeka chifukwa cha kuwonongeka kwakuthupi, monga matalala kapena makina ogwiritsidwa ntchito panthawi yoyika.

3.Ubwino waUfa wa Polima Wosungunukanso (RDP)mu Zogulitsa Zouma
Ufa wa Redispersible Polymer (RDP) umathandizira kwambiri magwiridwe antchito a zinthu zouma za matope, zomwe zimapangitsa kuti zinthu izi zikhale zabwino:
a.Kumamatira Kowonjezereka
RDP imakulitsa mphamvu yolumikizirana pakati pa matope ndi zinthu zina, zomwe ndizofunikira kwambiri pakugwiritsa ntchito monga zomatira za matailosi ndi zomatira zokonzanso, komwe kumamatira mwamphamvu kumafunika kuti tipewe kusweka kapena kulephera pakapita nthawi.
b.Kukana kwa Ming'alu
Kusinthasintha komwe kumaperekedwa ndi RDPs kumalola makina a matope kuti azisinthasintha ndi kutentha, zomwe zimachepetsa chiopsezo cha ming'alu. Kapangidwe kameneka ndi kofunikira kwambiri pa ntchito zakunja, monga ma plaster ndi ETICS, komwe kuyenda kwa nyumba kapena nyengo yoipa kwambiri kungayambitse ming'alu.
c.Kukana Madzi
Pa ntchito zonse zamkati ndi zakunja, ma RDP amathandizira kuti madzi asalowe bwino, zomwe zimathandiza kuti chinyezi chisalowe. Izi zimathandiza kwambiri m'malo onyowa, zomwe zimathandiza kuti zinthu zomangira zikhale zokhalitsa komanso zolimba.
d.Kugwira Ntchito Bwino
Ma mortar okhala ndi RDP ndi osavuta kugwiritsa ntchito, kuwafalitsa, ndi kuwasintha, zomwe zimapangitsa kuti ogwiritsa ntchito azisangalala ndi ntchito yawo yonse. Uwu ndi mwayi waukulu pa zomatira za matailosi ndi kukonza mortars, komwe kugwiritsa ntchito mosavuta kungathandize kuti ntchito yomanga ipite patsogolo.
e.Kulimba
Ma mortar okhala ndi Redispersible Polymer Powder (RDP)s ndi osavuta kuwononga, zomwe zimapangitsa kuti ntchito yawo ikhale yolimba nthawi yayitali ngakhale pamavuto osiyanasiyana azachilengedwe.
Ufa wa Polima Wosungunukanso (RDP)Ma RDP ndi zinthu zofunika kwambiri popanga ma mortar apadera ouma, zomwe zimawonjezera mphamvu zawo zakuthupi monga kumatira, kusinthasintha, kugwira ntchito, komanso kulimba. Kaya amagwiritsidwa ntchito mu zomatira za matailosi, ma plaster, ma mortar okonzanso, kapena makina otenthetsera akunja, ma RDP amawongolera kwambiri magwiridwe antchito ndi moyo wautali wa chinthucho. Pamene miyezo yomanga ikupitilira kufunikira zipangizo zapadera, kugwiritsa ntchito ma RDP mu mortar ouma kudzapitilizabe kugwira ntchito yofunika kwambiri pakukwaniritsa zosowa izi.
