Kubwezeretsani polima ufa (RDP) ndi polymer omwe amagwiritsidwa ntchito ngati owonjezera mu mativa owuma. RDP ndi ufa wopangidwa ndi kupukuta kupukuta elilsion. RDP ikawonjezeredwa ku madzi zimapanga emulsion yokhazikika yomwe ingagwiritsidwe ntchito kupanga matope. RDP ili ndi zinthu zambiri zomwe zimapangitsa kuti zikhale zowonjezera mtengo zouma mafoni. Izi zikuphatikiza:
Kusungidwa kwamadzi: RDP imathandizira kusunga madzi m'toto pachitaya, motero kukonza kugwirira ntchito matope ndikuchepetsa kuchuluka kwa madzi omwe amafunikira.
Modelion: RDP imatha kukonza zomatira pakati pa matope ndi gawo lapansi, ndipo mwakulitsa mphamvu ndi chikhazikitso cha matope.
Kugwira ntchito: RDP imatha kusintha mtundu wa chinthu chomalizidwa popanga matope osavuta kukonza.
Kukhazikika: RDP imatha kuwonjezera kukhazikika kwa matope, kupangitsa kuti ikhale yolimbana ndi nyengo.
RDP ndi zowonjezera zambiri zomwe zingagwiritsidwe ntchito m'malo osiyanasiyana osakanikirana. Ndizoyenera kwa matope zomwe zimagwiritsidwa ntchito kunja ngati zomata za stucco ndi tiles. RDP ikhoza kugwiritsidwanso ntchito m'matalemba omwe amagwiritsidwa ntchito mkati mwazinthu monga mafilimu ophatikizira ndi mankhwala okonza.
Nazi maubwino ena ogwiritsa ntchito rdp mu matope osakaniza:
Sinthani kusungidwa kwamadzi
Sinthani Mode
Sinthani Kuthana
Kuchulukitsa
Kuchepetsa kusokonekera
Chepetsani kuwonongeka kwa madzi
Kuchulukitsa kusinthasintha
Sinthani nyengo
RDP ndi zowonjezera bwino komanso zothandiza zomwe zingagwiritsidwe ntchito kukonza matope osakaniza owuma. Ndi chida chamtengo wapatali kwa makontrakitala ndi omanga omwe akufuna kupanga matope okhazikika.
Nazi zina mwazinthu zodziwika bwino za RDP zomwe zimagwiritsidwa ntchito mu matope osakaniza:
Vinyl acetate ethylene (Vae): VAE RDP ndi mtundu wamba wa RDP. Ndi njira yotsika mtengo komanso yotsika mtengo yomwe ingagwiritsidwe ntchito m'matangole osiyanasiyana.
Styrene butadiene acrylate (SBR): SBRS RDP ndi njira yotsika mtengo kuposa VAE RDP, koma imapereka kusungidwa kwabwino kwamadzi komanso kutsatira.
Polyirethane (PU): PE RDP ndiye mtundu wokwera mtengo kwambiri, koma ili ndi chisungiko chabwino kwambiri, kutsatira ndi kulimba.
