Inganda za Chongqing zikora ibijyanye na aluminiyumu mu nganda zateye imbere cyane mu myaka ya vuba aha, kandi zagiye zihura n'igihugu cyose buhoro buhoro. Ikoranabuhanga rya anodizing ni bumwe mu buryo bukunze gukoreshwa mu nganda za Chongqing zikora ibijyanye na aluminiyumu mu nganda. Abakoresha bashya benshi ntabwo bazi byinshi ku bijyanye no gukora anodizing, reka tubahe incamake irambuye.
Uburyo bwo gutunganya ogisijeni ku miterere ya aluminiyumu mu nganda muri Chongqing;
1. Gutunganya ubuso.
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.
2. Uburyo bwo gukuraho amavuta ku buso.
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.
3. Uburyo bwo gukata aside.
Uburyo bwo gukata aside hejuru ni ugukora igikorwa cyo gukata aside hejuru nyuma yo gukuraho amavuta kuri aluminium, kandi intego nyamukuru yo kuyikuraho ni ugukuraho oxide ikozwe na oxidation y'ibindi bintu by'icyuma ku buso bwa aluminium na oxide film ikozwe na oxide karemano; Nyuma yo gutunganya aside corruption, 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 corruption irimo umuringa, ubuso buhinduka umwijima nyuma yo gupima aside corruption, kandi igomba kwinjizwa mu gikoresho cya aside nitrique mu gihe cy'iminota 3-5 kugira ngo ubuso bube ifeza yera.
4. Uburyo bwo gukata aluminiyumu.
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. Gukata alkali ku buso bwa aluminiyumu bigira uruhare runini mu bwiza rusange bw'ubuso bwa aluminiyumu.
5. Uburyo bwo kutagira aho ubogamiye.
Intego yo gukuraho imyanda cyangwa ibintu nk'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.
6. Uburyo bwo kuvura indwara yo gusiga amavuta.
Uburyo bwo kuvura okiside ya anodi 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 anodide ya aluminium profile rufite ubukana bwinshi no kudahangarwa no kwangirika, ubunini busanzwe ni 10-12μ m, bishobora kunoza neza ubudahangarwa bwo kwangirika bwa aluminium profile n'ubwiza bwa aluminium profile.
Uburyo bwo gusiga irangi ry’aside bufite uruhare runini mu bwiza no kuramba kwa aluminiyumu yo mu nganda za Chongqing.
