Nigute icyapa gisize amabara kigera ku kurwanya ruswa? Icyapa gisize amabara, kizwi kandi nk'icyuma gisize amabara, ni ibisubizo by'ibikorwa byahujwe no gutwikira, mbere yo kuvura, primer, na topcoat. Tuyita "bane muri sisitemu imwe yo kurwanya ruswa y'ibyuma bisize amabara". Ikibaho cyibara ryibara ryakozwe mubirango bitandukanye byambarwa kandi bisizwe mubyiciro 5 nibikorwa 48, hamwe nibintu byiza birwanya ingese
Kurwanya ruswa no kurwanya kuramba kuramba.

Nigute dushobora kugera kuri anti-ruswa yamabara yometseho ibyuma? Icyapa gisize amabara, kizwi kandi nk'icyuma gisize amabara, ni ibisubizo by'ibikorwa byahujwe no gutwikira, mbere yo kuvura, primer, na topcoat. Tuyita "bane muri sisitemu imwe yo kurwanya ruswa ya plaque isize amabara".
Igipfundikizo cyicyuma cyamabara kigira uruhare mukurwanya ruswa. Muri make, yongerera igihe cyumurimo icyapa cyicyuma mukomeza gukoresha igifuniko cyacyo. Birumvikana, ubwoko, ubwiza, nubunini bwikibiriti nibintu byingenzi muburebure bwigihe cyo gukoresha. Ibara ryacu ryometseho ibyuma bikoresha cyane cyane galvanis, zinc ya aluminium, magnesium ya aluminiyumu hamwe nibindi byuma bisize ibyuma biva mu nganda nini zo mu rugo, bifite imbaraga nyinshi kandi birwanya ruswa.
Reka twongere tuvuge kubyerekeranye mbere yo kuvura. Iki nigice cyingenzi cyo kurwanya ruswa yibyuma byamabara, akenshi birengagizwa. Imbere yo kuvura, izwi kandi nka passivation layer, isaba gukoresha ibisubizo bya passivation nka fosifate cyangwa chromate kugirango inyuze hejuru yubutaka mbere yo gutwikira amabara. Ibi ntabwo byongera gusa gufunga igifuniko, ahubwo binagira uruhare mukurwanya ruswa. Ubushakashatsi bwerekanye ko mu igeragezwa ryo kurwanya umunyu utagira aho ubogamiye w’amasahani yometseho amabara, igipimo cy’imisanzu y’ubuvuzi mbere yo kuvura kigera kuri 60%.
Reka twongere tuvuge kuri primer. Ku ruhande rumwe, primer igira uruhare mukwiyongera kwifata. Iyo firime irangi imaze kwemerwa, ntishobora gutandukana nigitambaro, ikarinda kubyimba no gutandukana. Kurundi ruhande, bitewe nuko hariho pigment irekura buhoro nka chromates muri primer, irashobora kwanduza anode no kunoza ruswa yo kwangirika.

Hanyuma, reka tuganire kuri topcoat. Usibye ubwiza, ikoti yo hejuru ikora cyane kugirango ibuze izuba kandi irinde kwangirika kwa UV. Iyo ikote rimaze kugera ku mubyimba runaka, rirashobora kugabanya ibisekuruza bya micropore, bityo bikarinda kwinjira mu bitangazamakuru byangirika, bikagabanya amazi na ogisijeni byinjira, kandi bikarinda kwangirika. Kurwanya UV hamwe nubucucike bwimyenda itandukanye biratandukanye, kandi kubwoko bumwe bwo gutwikira, ubunini bwa firime irangi nikintu cyingenzi kigira ingaruka mbi. Ibibaho bitwikiriye amabara bikozwe muguhitamo ibirango bitandukanye byamavuta byakize mubushyuhe bwinshi, bikaviramo kurwanya ruswa cyane hamwe nigihe kirekire cyo kurwanya gushira.
