Mwisi yisi yo guhimba ibyuma, kuvura hejuru yicyuma kitagira umwanda ninzira ikomeye yongerera ibikoresho igihe kirekire, gushimisha ubwiza, no kurwanya ruswa. Muri Sosiyete ya Jindalai Steel, dufite ubuhanga bwo gutanga ibicuruzwa byiza byo mu rwego rwo hejuru bitagira umwanda, kandi twumva akamaro k'uburyo bwiza bwo kuvura hejuru. Iyi blog izacengera muburyo butandukanye bwo kuvura ibyuma bidafite ibyuma, byibanda kubikorwa bisanzwe: gutoragura no gutambuka.
Nubuhe buryo bwo Kuvura Ubuso Kubyuma bitagira umwanda?
Uburyo bwo kuvura hejuru yicyuma kitagira umwanda burashobora gushyirwa mubice muburyo bwa mashini na chimique. Uburyo bwa mashini burimo gusya, gusya, no guturika, bihindura umubiri muburyo bwo kunoza kurangiza no gukuraho ubusembwa. Uburyo bwa shimi, kurundi ruhande, burimo gushyira mubikorwa ibisubizo byihariye kugirango ugere kubintu byifuzwa, nko kurwanya ruswa.
Gutoranya na Passivation: Inzira zingenzi
Babiri muburyo bukoreshwa cyane muburyo bwo kuvura imiti kubutaka butagira umwanda ni ugutoragura no gutambuka.
Gutoragura ni inzira ikuraho oxyde, igipimo, nibindi byanduza hejuru yicyuma kitagira umwanda. Ibi mubisanzwe bigerwaho hifashishijwe imvange ya acide, nka hydrochloric cyangwa acide sulfurike. Uburyo bwo gutoragura ntibusukura gusa ahubwo binategura ubundi buryo bwo kuvura, byemeza neza ko bifatanye neza cyangwa bikarangira.
Ku rundi ruhande, Passivation, ni inzira izamura urwego rwa okiside karemano ku byuma bitagira umwanda, bitanga inzitizi yinyongera yo kwangirika. Ubusanzwe ibyo bigerwaho no kuvura icyuma nigisubizo kirimo aside citric cyangwa nitric. Passivation ningirakamaro mugukomeza ubusugire bwibyuma bitagira umwanda mubidukikije bikaze, bikaba intambwe yingenzi mubikorwa byo kuvura hejuru.
Amabwiriza yihariye yo gutoranya no gutambuka
Ku bijyanye no gutoranya no gutambuka, gukurikiza amabwiriza yihariye ni ngombwa kugirango ugere ku bisubizo byiza.
1. Amabwiriza yo Kuvura Gutoranya:
- Menya neza ko ibyuma bitagira umwanda bisukuye kandi bitarimo amavuta cyangwa umwanda.
- Tegura igisubizo cyo gutoranya ukurikije amabwiriza yakozwe nuwabikoze, urebe neza ko acide ikwiye.
- Shira ibyuma bitagira umwanda mubisubizo mugihe cyateganijwe, mubisanzwe kuva muminota mike kugeza kumasaha menshi, bitewe nubunini bwurwego rwa oxyde.
- Koza neza n'amazi kugirango ugabanye aside kandi ukureho ibisigisigi byose.
2. Amabwiriza yo kuvura Passivation:
- Nyuma yo gutoragura, kwoza ibyuma bidafite ingese kugirango ukureho aside isigaye.
- Tegura igisubizo cya passivation, urebe ko cyujuje ibisabwa bisabwa.
- Shira ibyuma bitagira umwanda mugisubizo cya passivation mugihe cyagenwe, mubisanzwe hagati yiminota 20 kugeza 30.
- Kwoza n'amazi ya deioniyo kugirango ukureho igisubizo gisigaye cya passivation hanyuma wumishe ibice burundu.
Itandukaniro Hagati yo Gutoranya na Passivation
Mugihe gutoragura no gutambuka ari ngombwa mugutunganya ibyuma bitagira umwanda, bikora intego zitandukanye. Gutoragura byibanda cyane cyane ku gusukura hejuru no gukuraho ibyanduye, mugihe passivation igamije kuzamura urwego rwa okiside irinda, kunoza ruswa. Gusobanukirwa itandukaniro nibyingenzi muguhitamo uburyo bukwiye bwo kuvura bushingiye kubikorwa byihariye nibidukikije.
Umwanzuro
Muri Jindalai Steel Company, tuzi ko gutunganya hejuru yicyuma kitagira ingese atari intambwe mubikorwa byo gukora; nikintu cyingenzi kigena kuramba nigikorwa cyibicuruzwa byanyuma. Mugukoresha tekinoroji igezweho yo kuvura ibyuma, harimo gutoragura no gutambuka, turemeza ko ibicuruzwa byacu byujuje ubuziranenge bwo hejuru kandi burambye. Waba ukeneye ibyuma bidafite ingese kubwubatsi, ibinyabiziga, cyangwa izindi nganda zose, ubuhanga bwacu mubikorwa byo gutunganya ibyuma byemeza ko wakiriye ibisubizo byiza bishoboka kubyo ukeneye.
