Kubwezeretsedwanso polima (RDP) ndi polymer omwe amagwiritsidwa ntchito pamapulogalamu osiyanasiyana. RDP ndi ufa wosungunuka wamadzi wopangidwa ndi ma poizoni osiyanasiyana, kuphatikizapo vinyl acetate, vinyl acetate ethylene, ndi ma acrylic. Ufa umasakanizidwa ndi madzi ndi zina zowonjezera kuti apange malo osalala, omwe amafunsira magawo osiyanasiyana. Pali mitundu ingapo ya RDP, iliyonse yomwe ili ndi katundu wake wapadera komanso kugwiritsa ntchito. Munkhaniyi, tiona zina mwazinthu zodziwika bwino za rdp ndi ntchito zawo.
1. Vinyl acetate wobwezeretsedwa polymer
Vinyl acetate adasinthidwa ma polima okwera ndi mtundu wamba wa RDP. Amapangidwa kuchokera ku vinyl acetate ndi vinyl acetate ethyle cololymer. Tinthu tating'onoting'ono timamwazikana m'madzi ndipo imatha kuphatikizidwanso munthawi yamadzi. Mtundu wamtunduwu uli ndi ntchito zingapo kuphatikiza matiti owuma, zinthu zosakaniza ndi simenti komanso zodzikongoletsera. Amapereka zikhalidwe zabwino kwambiri, kusinthasintha ndi kulimba.
2.
Acrylic adasinthidwa ma policy opangidwa kuchokera ku ma acrylic kapena methacrylic. Mphamvu zawo zapadera ndipo kutsutsana kwawo kwa Abrasion kumawapangitsa kukhala abwino kugwiritsira ntchito komwe kulimba kuli kotsutsa. Amagwiritsidwa ntchito m'masewera a tile, kusokonekera kwa kunja ndi matembenuzidwe omaliza (maboma), ndikukonza matimeni.
3..
Ethylene-vanyl acetate osinthidwa oyipitsitsa amapangidwa kuchokera ku Ethylene-Vinyll Acetate ardwelymers. Amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo maphero a simenti, ma grout ndi tiilo omata. Ali ndi kusinthasintha kosintha bwino komanso kutsatira malo osokoneza bongo.
4.
Styrene-Buydiene anasinthanso ma polipo omwe amapangidwa kuchokera ku Optyre-butadiene oplorrs. Amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikiza mayangole konkriti, zomata za matabwa ndi zopukutira. Ali ndi madzi abwino kwambiri komanso zomatira.
5. Re-emulsifer polmer ufa
Kubwezeretsanso polity ufa ndi rdp yopangidwa kuti ikonzedwe m'madzi mutayanika. Imagwiritsidwa ntchito pamapulogalamu ambiri omwe malonda amawonekera m'madzi kapena chinyezi mutatha kugwiritsa ntchito. Izi zimaphatikizapo zomata za matayala, grout, ndi koumba. Ali ndi madzi abwino kwambiri komanso kusinthasintha.
6. Hydrophobic adabwezeredwa polima ufa
Mafuta a Hydrophobic Ofesedwa Polima adapangidwa kuti awonjezere madzi kukana zopangidwa ndi simenti. Nthawi zambiri imagwiritsidwa ntchito pogwiritsa ntchito komwe mankhwalawa amakumana ndi madzi, monga kusokonezeka kwa kunja ndikumaliza njira zomatira (zomata zamiyala yolowera ndi matembenuzidwe? Imakhala ndi madzi abwino kwambiri komanso kulimba.
Kubwezeretsedwanso ndi ufa wa latx ndi zinthu zomwe zingagwiritsidwe ntchito pamapulogalamu ambiri. Pali mitundu ingapo ya RDP, iliyonse yomwe ili ndi katundu wake wapadera komanso kugwiritsa ntchito. Chifuno chabwino kwambiri, kusinthasintha ndi kulimba kumawapangitsa kuti azigwiritsa ntchito zinthu zosiyanasiyana. Mukamagwiritsa ntchito moyenera, amatha kuthandiza kukonza bwino komanso nthawi yayitali ya zinthu zomanga.
