Inzira nyamukuru yo kuvura ibyuma bya Oxidation

Kuvura okiside yibyuma nugukora firime irinda okiside hejuru yicyuma binyuze mumikoranire ya ogisijeni cyangwa okiside, birinda kwangirika kwicyuma. Uburyo bwa okiside burimo okiside yumuriro, okiside ya alkaline, na okiside ya aside

Kuvura okiside yibyuma nugukora firime irinda okiside hejuru yicyuma binyuze mumikoranire ya ogisijeni cyangwa okiside, birinda kwangirika kwicyuma. Uburyo bwa okiside burimo okiside yumuriro, okiside ya alkaline, okiside ya aside (kubutare bwumukara), okiside yimiti, okiside ya anodic (kubutare butari ferrous), nibindi.

Shyushya ibicuruzwa kugeza kuri 600 ℃ ~ 650 ℃ ukoresheje uburyo bwa okiside yumuriro, hanyuma ubivure ukoresheje amavuta ashyushye kandi ugabanye ibintu. Ubundi buryo ni ugucengera ibicuruzwa byicyuma mumyunyu ya alkali yashongeshejwe hafi 300 ℃ kugirango bivurwe.

Mugihe ukoresheje uburyo bwa okiside ya alkaline, shira ibice mumuti wateguwe hanyuma ubishyuhe kuri 135 ℃ kugeza 155 ℃. Igihe cyo kuvura giterwa nibirimo karubone mubice. Nyuma yo kuvura okiside ibice byicyuma, kwoza amazi yisabune irimo 15g / L kugeza 20g / L kuri 60 ℃ kugeza 80 ℃ muminota 2 kugeza 5. Noneho ubyoze n'amazi akonje kandi ashyushye hanyuma uhumure cyangwa wumishe muminota 5 kugeza 10 (ku bushyuhe bwa 80 ℃ kugeza 90 ℃).

Uburyo bwa 3 okiside ya aside ikubiyemo gushyira ibice mumuti wa acide kugirango bivurwe. Ugereranije nuburyo bwa okiside ya alkaline, uburyo bwa okiside ya acide nubukungu. Filime ikingira yakozwe hejuru yicyuma nyuma yo kuvurwa ifite imbaraga zo kurwanya ruswa ndetse nimbaraga za mashini kuruta firime yoroheje yakozwe nyuma yo kuvura alkaline okiside

Uburyo bwa okiside ya chimique burakwiriye cyane cyane kuvura okiside yibyuma bidafite fer nka aluminium, umuringa, magnesium, hamwe na alloys. Uburyo bwo gutunganya ni ugushyira ibice mubisubizo byateguwe, hanyuma nyuma ya reaction ya okiside runaka mubushyuhe runaka mugihe runaka, harakorwa firime ikingira, ishobora noneho guhanagurwa no gukama.

Uburyo bwa Anodizing nubundi buryo bwo okiside yibyuma bidafite ferrous. Nibikorwa byo gukoresha ibice byicyuma nka anode nuburyo bwa electrolytike kugirango bakore firime ya oxyde hejuru yabo. Ubu bwoko bwa firime ya okiside irashobora gukora nka firime ya passivasi hagati yicyuma na firime, ndetse no kongera imbaraga zihuza hagati yimyenda nicyuma, kugabanya ubwinjira bwamazi, bityo bikongerera igihe cyakazi cyo gutwikira. Irakoreshwa cyane murwego rwo hasi rwo gushushanya.
