Imikoreshereze
Acide ya oxalicIgisubizo gisanzwe ni igisubizo cya oxalic hamwe nibitekerezo bizwi kandi bikoreshwa cyane mumirima nkisesengura rya shimi, umusaruro winganda, umusaruro, nubushakashatsi bwa siyansi. Uburyo nyamukuru bwo gusaba ni ibi bikurikira:
Isesengura rya shimi no kwiyemeza
- Aside - imigambi shingiro: Acide oxalic ni aside ifite intege nke za dibasic zishobora kunyuramo kutabogama hamwe nibishingiro. Irashobora gukoreshwa nkigisubizo gisanzwe cya acide kugirango umenye kwibanda kubintu bitazwi - igisubizo cya Alkaline. Kurugero, iyo tithiride yamashanyarazi ya sodium hamwe nigisubizo cya oxalic gisanzwe, ukoresheje phenolphthalein nkigipimo cyimiti ya sodium irashobora kubarwa hashingiwe ku mibanire ya oxalic yakoreshejwe mu mpera - Ingingo y'igiciro.
- Kugarura imigambi: Ikintu cya karubone muri aside oxalike gifite agaciro ka +3, kwerekana kunanirwa no gushobora kubyitwaramo no kubyakira amavuta akomeye muri reaction ya reaction. Muri acide ya acide, sodium oxalate irashobora kugirirwamo na potasiyumu permanganate. Gukoresha iyi reaction, igisubizo cya oxalic gisanzwe gishobora gukoreshwa mugukoresha neza kwibanda kuri potasiyumu.
Igenzura ryiza
- Kuvura neza kwicwa: muburyo bwo kuvura hejuru yibyuma nka aluminiyumu, ibisubizo bya Oxalic birashobora gukoreshwa mugusiganwa no gukora isuku. Ukoresheje acide ya acide acide, igisubizo cyigisubizo kirashobora kugenzurwa neza kugirango habeho guhuzagurika no guturika kwingaruka zo kuvura ibicuruzwa, bityo biteza imbere ubuziranenge. Kurugero, muguhuza ibitekerezo bya acide ya oxalic igisubizo cyihariye murugero runaka, ibicuruzwa bya aluminium birashobora guhindurwa kugirango ubone ikintu kimwe kandi cyiza.
- Inganda za electraplang: Igisubizo cya Oxalic gisanzwe gishobora gukoreshwa muguhindura acide hamwe nibigize igisubizo cya electraplating, kugenzura ubuziranenge n'imikorere ya electraplated the layer. Kugenzura neza acide ya oxalic bifasha kunoza ubumwe, uburebure, no kurwanya ruswa, kureba ko ibicuruzwa byatoranijwe byujuje ubuziranenge.
Gupakira no kohereza
25Kg / ingoma cyangwa nkibisabwa kubakiriya.
Kohereza: Ubwoko 6 bwibicuruzwa biteye akaga kandi birashobora gutanga ninyanja.
Bika no Kubika
Ubuzima bwa Aclf: Ukwezi 24 kuva ku munsi wo gukora mu gupakira mu buryo budasubirwaho bubitswe ahantu hakonje hatari izuba, amazi.
Ububiko buhumeka, ubushyuhe buke bwumye, bitandukanijwe na oxidants, acide.
