Uburyo bwo gutegura aside ya oxalic bukurikije amategeko
Uburyo bwo gutegura umuti bugomba gukurikiza amabwiriza yo mu rwego rwa laboratwari. Ubwa mbere, hitamo ibikoresho bikozwe muri polyethylene ifite ubucucike bwinshi (HDPE), itanga ubushobozi bwo kurwanya aside oxalic ugereranyije na pulasitiki isanzwe. Ibikoresho by'ikirahure bishobora gukoreshwa igihe gito, ariko kubikwa igihe kirekire bishobora gutuma iyoni ya sodium isohoka, bigatera ingaruka ku buryo umuti udahinduka.
Mu gihe utegura, banza upime ingano y'amazi akenewe, hanyuma usuke buhoro buhoro aside oxalic ku ruhande rw'ikintu. Iyi gahunda ntigomba guhinduka. Igerageza ryerekana ko kongera amazi muri aside yikubise bitera ingaruka z'ingufu zidasanzwe zigera kuri dogere 80–100°C, bishobora gutera impanuka zo gushwanyagurika. Gukurikiza urutonde rwiza bituma ubushyuhe buzamuka mu rugero rwiza.
Mu gukangura, koresha agakoresho ko gukangura karimo ikirahure cyangwa polytetrafluoroethylene (PTFE), hanyuma uvange buri gihe mu minota 5-7 kugeza igihe umuti uvuye neza. Menya ko gushonga kwa aside oxalic ari inzira yo kuvanga. Reka umuti wateguwe uhagarare iminota 20-30 kugira ngo ugere ku bushyuhe bw'icyumba, aho pH izahagarara neza mu rugero rwa 1.5-2.0.
Aside ya Oxalike – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ni uruganda rwizewe kandi rutanga aside oxalic nziza cyane (aside ethanedioic, CAS 144 62 7) ifite icyicaro gikuru i Zibo, Shandong, mu Bushinwa. Aside oxalic yacu iboneka mu bwoko bwa anhydrous (C₂H₂O₄, MW 90.03) na dihydrate (H₂C₂O₄·2H₂O, MW 126.07), ifite ubuziranenge bwa nibura 99.6%. Igaragara nk'amakristu adafite ibara cyangwa ifu y'umweru ya kristu, nta mpumuro, kandi irashongesha cyane mu mazi na ethanol.
Yakozwe hakurikijwe igenzura rikomeye ry’ubuziranenge n’uburyo bwemejwe na ISO 9001, aside oxalic yacu yujuje ibisabwa mu nganda no mu buryo bworoshye hamwe n’imyanda mike (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Nk’aside dicarboxylic ikoreshwa mu buryo butandukanye kandi igabanya ubukana, ikora nk’ikintu cy’ingenzi gikuraho uburozi, ikintu gikuraho uburozi, n’ikintu gikoreshwa mu burozi. Ikoreshwa cyane mu gutunganya icyuma (gukuraho ingese, gusiga irangi ku myenda), gusiga irangi no gucapa imyenda (mordant, bleach), gusiga ibara ry’uruhu, gusiga marble, no gutunganya amazi. Ni ingenzi kandi mu gukuramo ibintu bidakunze kuboneka mu butaka, gukora organic synthesis (oxalate salts/esters), imiti ikoreshwa mu burozi, no mu gutunganya ibikoresho byo gusukura.
Muri Anhao Chemical, twemeza ko ibicuruzwa byacu bitangwa neza, ko bigenzurwa neza kandi bipfunyitse neza: imifuka ya 25kg, 500kg/1000kg FIBC, na ISO tanks. Dufite uburambe mu myaka myinshi mu gukora no kohereza ibicuruzwa mu mahanga, dutanga aside oxalic ku bakiriya bo muri Aziya y'Amajyepfo y'Uburasirazuba, i Burayi, mu Burasirazuba bwo Hagati, n'ahandi, dushyigikiwe n'inkunga y'abahanga mu bya tekiniki n'ibikoresho bigezweho. Twiyemeje gutanga ibisubizo bya aside oxalic byiza kandi bihendutse byagenewe ibyo mukeneye mu nganda no mu bucuruzi.
