Uruganda rukora aluminiyumu ikora muri Chongqing rukubwira uburyo bwo gutwika aluminiyumu.

Gutunganya ubuso, bizwi kandi nka surface pretreatment, ni ugukuraho umwanda uri ku buso bwa aluminiyumu hakoreshejwe ibintu bifatika n'ibinyabutabire, kugira ngo ubashe kugera ku mubiri wa aluminiyumu, ibyo bikaba byoroshye mu gutunganya ogisijeni ku buso bwa aluminiyumu mu gihe cya nyuma.

Intego yo gukuraho amavuta ni ugukuraho amavuta yo mu nganda, amavuta arwanya kwangirika n'umwanda ufatanye n'ubuso bwa aluminiyumu, kugira ngo habeho kwangirika kwa alkali kuri aluminiyumu imwe n'isuku y'ikigega cya alkali. Kongera ireme ryo gutunganya ubuso bwa aluminiyumu.

Uburyo bwo gukata aside ku buso ni ugukora igikorwa cyo gukata aside ku buso nyuma yo gukuraho amavuta kuri aluminium, kandi intego nyamukuru yo kuyikuraho ni ugukuraho okiside ikozwe na okiside y'ibindi bintu by'icyuma ku buso bwa aluminium na okiside ikozwe mu buryo busanzwe na oxide; Nyuma yo gutunganya aside, ni ngombwa kuyimesa ako kanya, kandi ubushyuhe bwo kuyisukura bugomba kugenzurwa na 50°C mbere kugira ngo hirindwe ibimenyetso by'amazi ku buso bwa aluminium, hanyuma ukayisukura n'amazi atemba. Kubera ko aluminium irimo umuringa, ubuso buhinduka umwijima nyuma yo gupima aside, kandi bugomba kwinjizwa mu gikoresho cya aside nitrike mu gihe cy'iminota 3-5 kugira ngo ubuso bube ifeza yera.

Intego y'ibanze yo gukata alkali ni ugukuraho ibintu bisigaye n'ibice byahindutse ku buso bwa aluminiyumu mu gihe cyo gukaraba, no gukuraho ubusembwa bwasigaye ku buso bwa aluminiyumu mu gihe cyo gukaraba. Gutunganya ubuso bwa aluminiyumu mu gukata alkali bigira uruhare runini mu bwiza rusange bw'ubuso bwa aluminiyumu.

Intego yo gukuraho imyanda cyangwa ibintu bibi nka umuringa, manganese, icyuma, silikoni, nibindi bitavangwa mu gisubizo cya alkali bisigaye ku buso bwa aluminiyumu nyuma yo gukata aside no gukata alkali. Muri rusange, uburyo bwo gukuraho imyanda ya alkali bisigaye ku buso bwa aluminiyumu nyuma yo gukata alkali ni ugukoresha 30%-50% by'umuti wa aside nitrike. Ku ruganda rwa aluminiyumu rufite silicon nyinshi, hatoranywa aside ivanze ya aside nitrike na fluoride ya hydrogen ifite igipimo cya 1:3. Silikoni ikorana na hydrogen na hydrofluoric acid kugira ngo ikore aside fluosilicic, ikava ku buso bwa aluminiyumu.

Uburyo bwo kuvura okiside ya anode ni uko umuti ukoreshwa nk'uburyo bwo gusohora, hanyuma agace gasohoka ku mutwe kagatoranywa kugira ngo gakore filime ya okiside ku buso bwa aluminium profile, kugira ngo aluminium profile ibe ifite ubudahangarwa bukomeye bwo kwangirika. Kubera ko urwego rwo kurinda ruboneka kubera okiside ya anode ya aluminium profile rufite ubukana bwinshi no kudahangarwa no kwangirika, ubunini busanzwe ni10-12μm, bishobora kunoza neza uburyo aluminiyumu irwanya ogisijeni ndetse n'ubwiza bw'imiterere ya aluminiyumu.
