Ifu ya polymer ishobora kongera gushonga (RDP)ni ubwoko bw'inyongeramusaruro y'ifu ya polymer ikozwe muri emulsion ya polymer binyuze mu kumisha. Ikiranga cyayo cy'ingenzi ni ubushobozi bwayo bwo kongera kwivanga ikaba emulsion ihamye ya polymer iyo ihuye n'amazi, bityo igakora umurimo wo guhindura nk'uwa emulsion y'amazi muri sisitemu zitandukanye z'imyanda yumye. Gutangiza RDP byazamuye cyane ubushobozi bwo gukora, gufatana, no kuramba kw'ibikoresho by'ubwubatsi, bituma iba ingenzi cyane mu miterere ya none y'imyanda yumye n'imitako y'amatafari.
1.Ku bijyanye n'imikorere, RDP igaragaza ubushobozi bwo kongera gushonga no gukora firime. Iyo ifu ya RDP ivanze n'amazi, ikwirakwira vuba ikarema uduce duto twa emulsion, kandi mu gihe cyo kumisha, ikora firime ya polimeri ihoraho kandi ikomeye. Iyi firime ya polimeri ihuza neza inorganic aggregate n'ubuso bw'ubutaka, yongera imbaraga z'imifatanire n'ubworoherane. Uru ruvange rwa firime rufite kandi urwego runaka rwo guhindagurika, rugabanya itandukaniro riri hagati y'uruvange rw'ibanze n'urw'imbere, rukarinda gusenyuka no gushwanyagurika.
2.RDP ishobora kunoza cyane ubushobozi bwa mortiweri. Kongeramo ingano ikwiye ya RDP byongera cyane uburyo mortiweri ifata amazi, ikagira ubushyuhe, kandi ikagira amavuta meza, bigatuma ikoreshwa neza kandi ringana mu gihe bigabanya kuva amaraso no gucika kw'amazi. Byongeye kandi, RDP yongera ubushobozi bwa mortiweri bwo kurwanya kugwa no kwangirika kw'ifu, bigatuma ikoreshwa ry'urwego runini rikomera. Ku matiyo, RDP ikomeza isano iri hagati y'amatiyo n'ubutaka, bigatuma habaho kugumana neza igihe kirekire.
3.Mu bijyanye no kuramba, RDP igaragaza ubushobozi bwo kudacikamo ibice, kudakonja no gushonga, no kudahinduka kw'ikirere. Filimi ya polymeri ikora nk'imbogamizi ku bushuhe n'imyuka, ikagabanya kwinjira k'ubushuhe bwo hanze bityo ikagabanya gusaza kw'ibirungo. Ndetse no mu bihe by'ubushyuhe n'ubukonje cyangwa ahantu hakonje, ibikoresho byahinduwe na RDP bigumana imbaraga nyinshi kandi bifatanye, ibi bikaba ari ingenzi cyane ku buryo bwo gukingira inkuta zo hanze no gusana ibirungo.
4.Mu rwego rwa shimi, RDP ubusanzwe ni copolymer y’ibintu bitandukanye bya monomer, nka vinyl acetate-ethylene (VAE), acrylates, na styrene-butadiene. Ubwoko butandukanye bwa polymer bugena uburinganire hagati yo koroha, kudakoresha amazi, no gufatana. RDP zishingiye kuri VAE ni zo zikoreshwa cyane bitewe n’imikorere yazo myiza muri rusange. RDP zishingiye kuri acrylate zizwiho kudakoresha ikirere neza no kudakoresha ikirere neza, bigatuma zikoreshwa ku bikoresho byo hanze byo ku rwego rwo hejuru. RDP zishingiye kuri styrene-butadiene zikunze gukoreshwa mu buryo busaba ko ibintu bikomera cyane kandi bidashobora gukururwa.
5.Mu bikorwa bifatika, RDP zikoreshwa cyane mu buryo nk'imitako y'amatafari, sisitemu zo gukingira inyuma (EIFS), mortila zigenga, mortila zisana, mortila zibumba, mortila zirinda amazi, hamwe n'ibikoresho bihuza imiterere. Urugero, muri tile, RDP ziyongera cyane imbaraga z'imitako yumye n'iy'amazi ndetse n'ubushobozi bwo kwirinda kunyerera; muri mortila zibungabunga amazi, zongerera ubushobozi bwo koroha no kudacika; muri mortila zigenga amazi, RDP zinoza amazi atemba kandi zikagabanya ifu; naho muri mortila zibungabunga amazi, zongerera ubushobozi bwo kutamena no kurekura, zikongera ubushobozi bwo kurinda.
6.Binyuze mu miterere yayo myiza yo gukora filime ya polimeri hamwe n'ingaruka zayo zo guhuza ibintu bidafite umwimerere,RDPyongera cyane imikorere ya sisitemu z’imyanda zivanze n’amazi. Ntabwo binoza gusa ubunararibonye mu bwubatsi ahubwo binatanga kuramba no kwihuza n’ibikoresho, bigatuma biba inyongeramusaruro y’ingenzi mu kugera ku mikorere myiza no kudatezuka mu bikoresho by’ubwubatsi bigezweho. Hamwe n’iterambere rihoraho ry’ibikoresho by’ubwubatsi bizira ibidukikije na sisitemu z’imyanda zivanze n’amazi zikoresha ikoranabuhanga rihambaye, udushya mu ikoranabuhanga rya RDP n’uburyo bwo kubikoresha bizakomeza kwaguka, bikaba icyerekezo cy’ingenzi cy’ibikoresho by’ubwubatsi bikora neza mu gihe kizaza.
