Uburyo aside ya oxalic ikoreshwa mu gucapa no gusiga irangi imyenda

Imikoreshereze ya aside oxalike
Mu nganda z’imiti, aside oxalic ikoreshwa mu gukora pentaerythritol, cobalt oxalate, nickel oxalate, fuchsin y’ibanze, ibikoresho byuzuye byo gusesengura icyuma n’ubutaka, ibikoresho by’imiti, n’ibindi bicuruzwa.
Mu buryo bwihuse bwo gusiga irangi, ikora nk'ikintu gitanga ibara rikanaringaniza.
Ikora nk'ikintu gikuraho ubwatsi ku bimera by'ibyatsi n'ingano (ikoresha ubushobozi bwo kugabanya aside ya oxalic) kandi ikanakuraho ibara ry'umugese (aside ya oxalic ikorana n'icyuma kikarema oxalate y'icyuma ishongesha, ikoroha gukurwaho n'amazi, bityo ikavanaho ibara ry'icyuma ku myenda).
Uburyo aside ya oxalic ikoreshwa mu gucapa no gusiga irangi imyenda
(1) Gukuraho ibizinga by'ingese ku myenda
Iyo icyuma gihuye na ogisijeni n'ubushuhe mu kirere, gikora ikintu cy'ingenzi cyitwa ingese. Nubwo imiterere nyayo ihinduka bitewe n'imiterere, ingese zose ziba zirimo iyoni z'icyuma zivanze. Ingese ku myenda y'ipamba zigira inenge zidashira zigomba gukurwaho, kandi aside oxalic ni igikoresho cyiza cyo kuzikuraho. Ihame ni uko aside oxalic ikorana na iyoni z'icyuma zivanze (Fe³⁺) kugira ngo ikore iyoni y'amoniyoni isobeka, [Fe(C₂O₄)₃]³⁻, ishongeshwa byoroshye mu mazi. Ikoreshwa risanzwe ni 20 g/L ya aside oxalic ifite hafi 30 mL/L ya aside asetiki 98%.
Icyitonderwa: Aside ya Oxalic ishobora kwangiza imigozi. Nyuma yo kuyitunganya, imyenda y'ipamba igomba kozwa neza n'amazi meza kugira ngo akureho aside ya Oxalic yose isigaye. Iyo idasukuwe neza, aside ya Oxalic izajya yiyongera mu gihe cy'umuma, bigatera kwangirika gukomeye kwa fibre no gukora imyobo.
Aside ya oxalic ishobora kandi gukuraho ibara ry'ingese ku myenda ya nylon, bitabaye ibyo byatuma umuhondo uhinduka.
(2) Gukuraho umwuka wa aside azote mu gihe cyo gukora irangi rya Ingran
Iyo hakoreshejwe uburyo bwa sodium nitrite mu gucapa irangi ry’ingufu hamwe n’irangi rya naphthol, aside nitrite ikorwa mu gihe aside sulfurike ikura. Ibi bituma umunyu wa sodium wa naphthol AS ku mwenda ukora ibintu bitukura nk’umukara, bigatuma habaho ibara ry’umweru ritaringaniye. Kugira ngo aside nitrite ikureho, 1–2 g/L ya aside oxalic rimwe na rimwe yongerwa mu gisubizo cya aside sulfurike nk’ikintu kigabanya ubukana (gisimbura aside formic, urea, cyangwa sulfur). Aside oxalic igabanya aside nitrite ikajya mu mwuka wa azote, bikabuza HNO₂ gukorana na AS kugira ngo ikore ibintu by’umukara.
