Hariho izi mpinduka mubunini bwa aluminiyumu mbere na nyuma ya okiside!?

Abantu benshi bafite ikibazo: "Kuki imyenge iba nini nyuma ya okiside?" Ibi bigomba gusobanurwa uhereye kumahame ya okiside, okiside itandukanye no gutera cyangwa amashanyarazi, anodizing ikorerwa hejuru ya aluminiyumu, ni inzira yo kubyitwaramo hejuru kugirango ikore firime ya oxyde.

Muri rusange, imikurire ya firime ya oxyde ikubiyemo ibintu bibiri bikurikira: (1) uburyo bwo gukora film (2) uburyo bwo gusesa amashanyarazi ya firime;

Mugihe cy'amashanyarazi, ogisijeni na aluminiyumu bifitanye isano ikomeye, kandi substrate ya aluminiyumu ihita ikora urwego rwinzitizi zidafite inzitizi, uburebure bwacyo buterwa na voltage ya tank.

Bitewe nubunini bunini bwa atome ya alumina, iraguka, urwego rwa bariyeri ruba rutaringaniye, bikavamo gukwirakwizwa kutaringaniye, kugabanuka kworoheje muri conve, nini nini, kandi bitandukanye na convex.

Amashanyarazi yamashanyarazi no gusesa imiti ya H2SO4 bibera mu cyuho hifashishijwe umurima w’amashanyarazi, maze umwobo ugenda uhinduka umwobo n’urukuta rw’umwobo, kandi urwego rwa bariyeri rwimurirwa mu cyuho.

Icyuma cyangwa ibishishwa bikoreshwa nka anode, na firime ya oxyde ikorwa hejuru yayo na electrolysis. Filime ya oxyde yicyuma ihindura imiterere nubuso, nko kurangi amabara, kunoza ruswa, kongera imbaraga zo kwambara no gukomera, kurinda icyuma. Aluminium anodizing, aluminiyumu hamwe nuruvange rwayo bishyirwa muri electrolyte ihuye (nka acide sulfurike, aside chromic, aside oxyde, nibindi) nka anode, mubihe byihariye kandi bigatangaza amashanyarazi, electrolysis. Aluminium ya anodic cyangwa ibivanze byayo irahinduka okiside kugirango ikore urwego ruto rwa oxyde ya aluminiyumu hejuru, hamwe nubunini bwa microne 5 kugeza 30, kandi firime ikomeye ya anodic oxyde irashobora kugera kuri microne 25 kugeza 150.

Akazi kare

Muburyo bwo gukora firime ya oxyde, birakenewe gukora alkali etching na polishing akazi mugihe cyambere.

Kwangirika kwa Alkali ninzira yo gukuraho no kuringaniza firime ya okiside isanzwe (AL2O3) hejuru ya aluminium. Umuvuduko wo kwangirika kwa alkali uterwa nubushuhe hamwe nubushyuhe bwo kwiyuhagira kwa alkali, biterwa cyane nigipimo cyimiti ya alkali yangiza (sodium gluconate) nibiri muri ion ya aluminium (AL3 +). Ubuso bwa aluminiyumu, umva, uburinganire hamwe na okiside ya firime electroplating, alkali ruswa byose bigira uruhare rukomeye.

Intego ya alkali ni ugukuraho firime ya okiside ikozwe hejuru yibice bya aluminiyumu ukoresheje ubushyuhe cyangwa mubihe bisanzwe, hamwe namavuta asigaye akoreshwa mugihe cyo gukora amata no kubumba. Niba iki gikorwa cyakozwe neza kigena urufunguzo rwubwiza bwa firime ya anodic oxyde yabonetse. Ingingo z'ingenzi ugomba kwitondera ni izi zikurikira. Witonze ukore akazi keza ko kugenzura mbere yo kwangirika kwa alkali, wasanze bidakwiriye kuvura alkali kwangirika bigomba gutorwa mbere. Uburyo bwo kwitegura mbere yo gutera alkali bigomba kuba bikwiye kandi byuzuye. Menya neza tekinoloji yimikorere ya alkali ikora neza.

Bikorerwa kumashini isya, umwirondoro wa aluminiyumu ushyirwa kumeza yakazi buri gihe, kandi hejuru igakoraho kandi igasunikwa nuruziga rwihuta ruzunguruka ruzunguruka, kuburyo ubuso bworoheje kandi buringaniye, ndetse ningaruka zindorerwamo. ni Byagezweho. Kuringaniza bikunze gukoreshwa mubikorwa kugirango bikureho ibicuruzwa biva hanze, bityo nanone byitwa "gukanika imashini" muriki gihe.

incamake

Guhindura ingano ya aluminiyumu irashobora gutoranywa, bitewe nuburyo bwa okiside, igihe, nuburyo bwo kubanza kuvura.

Ingano ntoya: Mugihe cyose cya okiside, birakenewe kandi ko ushiramo aluminiyumu ya aluminiyumu mugisubizo cya acide sulfurike, uruhererekane rwibikorwa bizatera ruswa ya aluminiyumu, ubwo rero nitubona ibicuruzwa bya aluminiyumu, ubunini bwabyo bizaba ntoya kubera ruswa.

Ingano nini: Kugirango ukore okiside ikomeye, urashobora gukora ubunini rusange bwa aluminium aluminiyumu ifite kwiyongera cyane.

Ubwiza bwa aluminiyumu akenshi bwerekana kwiyongera kugaragara.
