Uburyo bw'ingenzi bwo kuvura ikoreshwa rya oxidation mu byuma

Uburyo bwo kuvura ogisijeni ku byuma ni ugukora agace ka ogisijeni gakingira hejuru y'ibyuma binyuze mu gukorana na ogisijeni cyangwa ogisijeni, ibyo bikarinda ingese y'icyuma. Uburyo bwo kuvura ogisijeni burimo ogisijeni y'ubushyuhe, ogisijeni y'ibikomoka kuri alkaline, na ogisijeni y'ibikomoka kuri aside.

Uburyo bwo kuvura ogisijeni ku byuma ni ugukora agace ka ogisijeni gakingira hejuru y'ibyuma binyuze mu gukorana na ogisijeni cyangwa ogisijeni, ibyo bikarinda ingese y'icyuma. Uburyo bwo kuvura ogisijeni burimo ogisijeni y'ubushyuhe, ogisijeni ya alkaline, ogisijeni y'aside (ku byuma byirabura), ogisijeni y'ibinyabutabire, ogisijeni ya anodike (ku byuma bitari feri), nibindi.

Shyushya ibikoresho by'icyuma kugeza kuri 600 ℃ ~ 650 ℃ ukoresheje uburyo bwo kugabanya ubushyuhe, hanyuma ubishyire mu mwuka ushyushye n'ibintu bigabanya ubushyuhe. Ubundi buryo ni ukwinjiza ibikoresho by'icyuma mu munyu wa alkali metal washongeshejwe ku bushyuhe bwa 300 ℃ kugira ngo bivurwe.

Mu gihe ukoresha uburyo bwa alkaline oxidation, shyira ibice mu gikoresho cyateguwe hanyuma ushyushye kugeza kuri dogere 135 kugeza kuri dogere 155. Igihe cyo kubitunganya giterwa n'ingano ya karuboni mu bice. Nyuma yo kubitunganya mu byuma, oza n'amazi y'isabune arimo 15g/L kugeza kuri 20g/L kuri dogere 60 kugeza kuri 80 ℃ mu gihe cy'iminota 2 kugeza kuri 5. Hanyuma ubisukemo amazi akonje n'ashyushye hanyuma ubihumeke cyangwa ubyumutse mu gihe cy'iminota 5 kugeza kuri 10 (ku bushyuhe bwa dogere 80 kugeza kuri dogere 90).

Uburyo bwa 3 bwo gusiga aside burimo gushyira ibice mu gisubizo cya aside kugira ngo bivurwe. Ugereranyije n'uburyo bwo gusiga aside, uburyo bwo gusiga aside burahendutse cyane. Agakoresho karinda kava ku buso bw'icyuma nyuma yo kuvurwa gafite ubudahangarwa bwinshi bwa corruption kandi gafite imbaraga nyinshi za mekanike ugereranyije n'agakoresho gato kavamo nyuma yo kuvurwa aside.

Uburyo bwo gusiga imyuka hakoreshejwe imiti bukwiriye cyane cyane mu kuvura ibyuma bitarimo feri nka aluminiyumu, umuringa, manyeziyumu, n'ibindi bikoresho byabyo. Uburyo bwo gutunganya ni ugushyira ibice mu gisubizo cyateguwe, hanyuma nyuma yo gukora ogisijeni ku bushyuhe runaka mu gihe runaka, hakorwa agace karinda, gashobora gusukurwa no kumyuka.

Uburyo bwo gusiga amavuta ni ubundi buryo bwo gusiga amavuta mu byuma bitari fer. Ni uburyo bwo gukoresha ibice by'icyuma nk'ama-anode n'uburyo bwa electrolytic kugira ngo hakorwe filimi za okiside ku buso bwabyo. Ubu bwoko bwa filimi ya okiside bushobora gukora nk'ifirime yo gufunga hagati y'icyuma n'ifirime yo gusiga, ndetse no kongera imbaraga zo guhuza hagati y'ifirime n'ibyuma, kugabanya kwinjira k'ubushuhe, bityo bikongera igihe cyo gukora ifirime. Ikoreshwa cyane mu gice cyo hasi cy'irangi.
