Okureeba ebintu omu bwijwire ahari Oxalic Acid
Oxalic acid, kandi emanyirwe nka ethanedioic acid, ni asidi erikukirayo kworoba kandi erimu enkora ya molekyu (COOH) 2 ⋅2H2O .
Nikireebeka nk’ebicupuri by’enyomyo ebitaine rangi kandi n’ekicweka ekirikukirayo omu bimera by’ebishaka, ebirikukira kubaho omu muringo gw’omunyugunyu gwa potassium nari calcium, obwo kirikushangwa nk’asidi y’obuntu omu bimera nka Chinese crabapple na banana. Oxalic acid nkye nayo neeshangwa omu nkari z'omuntu, kandi calcium oxalate niyo erikureetaho amabaare g'omu nkari. Ku birikwotsya kuhika ahari 100.1 °C, ebicupuri bya oxalic acid nibifeerwa amaizi gaabyo g’okuhinduka ebicupuri bikakora oxalic acid etaine maizi, erimu obutagatsi bwa 189.5 °C. Oxalic acid etaine maizi neebaasa kusheesheka omu maizi nari ethanol kwonka terikusheesheka omu ether. Omu laboratory, oxalic acid neebaasa kuvunda ahabw’okwotsya kubaasa kureetaho omuyaga gwa carbon monoxide.
Oxalic acid n’ekintu kikuru omu by’emibazi ekiine emirimo mingi kandi nikikoresibwa omu mirimo mingi. Ahabw’okutunguuka kw’eby’emibazi, erangi, n’okujwara ebijwaro n’okukingurwa kw’akatare k’ensi yoona, nikyetengyesa munonga okucondooza n’okukora oxalic acid.

Omubazi gwa Shandong Pulisi
Shandong Pulisi Chemical Co., Ltd., eyatandikire omu Kwaikumi 2006 kandi eine ekitebe kikuru omuri Zibo, Shandong, n’ekitongore ky’eby’obuhangwa ekikuru omu kugaba ebintu by’emibazi eby’omutindo gw’ahaiguru kandi ekiine ekigyere omu nsi yoona. Okwehayo aha nteekateeka ya “okuta omutima aha kutunguura emibazi y’omutindo”, kampuni egi etunguukire yaaba kampuni erimu buri kimwe erikugaita R&D, okukora, okuguza n’okutwara ebintu, n’ebitongore ebiine akakwate na Zibo Anhao Chemical Co., Ltd. na China Changrui Co., Limited.
Oxalic acid yaitu (CAS No.: 144-62-7 ahabw’ebitarimu maizi, 6153-56-6 ahabw’ebitarimu maizi) n’ekintu ky’omutaano, ekikozirwe kuhikiiriza omutindo gw’ensi yoona. Nikiboneka omu miringo ebiri ey’amakorero (obushemeire ≥96%) n’omutindo gw’okushemezibwa (obushemeire ≥99.6%), oxalic acid yaitu eriho nk’ebicupuri ebitarikureebeka gye (omu muringo gw’omutaano dihydrate) ebiine enkora ya molekyu C2H2O4·2H2O n’oburemeezi bwa molekyu bwa227. Nikigira okushohozibwa kw’amaani omu maizi n’omu ethanol, okukyendeeza kw’amaani, n’okugira asidi nyingi—ekirikugihindura emwe aha asidi z’amaani ezirikwetwa organic dicarboxylic acids.
Omutindo gwaitu nigukyeberwa munonga kukuratira emitindo ya ISO 9001:2015 kandi guhamibwe ebitongore ebiine obushoboorozi nka German BV, oxalic acid yaitu neekoresibwa munonga omu makorero maingi:
Okukora eby’ekyoma: Okuihaho obukyere omu muringo murungi, okuboneza eby’ekyoma n’okugumizamu eby’ekyoma, copper n’ebindi byoma.
Okwombeka: Ebintu ebikuru eby’okukoresa omu kujwanzya sementi n’okukora ebintu by’okwombeka.
Enkora y’eby’oruhu: Nizikoresibwa omu kujwara erangi, okurugaho amajuta n’okujwara oruhu.
Okuboneza amaizi: Chelating agent ahabw’okutunguura omutindo gw’amaizi n’okuihaho ebizimba.
Eby’okujwara n’okuteera ebitabo: Ekirikuhwera omu kujwara erangi n’okugijwara.
Amakorero g’emibazi n’eby’okurya: Nigakoresibwa omu kuteerana eby’okurya ebiri ahagati y’emibazi n’okukora eby’okurya ebirikwongera omu by’okurya.
Nitureeba ngu twine amabiikiro g’okwetongora omuri Qingdao, Tianjin, emyanya y’okushuutamamu eya Shanghai hamwe n’omu kicweka ky’obushuubuzi ekya Zibo, nituhamya ngu twahitsya ebintu omu muringo murungi ahari bakasitoma b’ensi yoona. Ebintu byaitu bihingwireho ebihandiiko bya REACH, FAMI-QS na SGS, kandi nibitwarwa omu mahanga n’ebicweka ebirikurenga 100 omuri Europe, America, Asia ey’omumashuma g’oburengyerwa-izooba, Middle East na Central Asia. Tutaireho enkoragana y’obumwe egumire ey’obwire buraingwa n’ebitongore ebimanyirwe munonga ebirimu PetroChina, CNOOC, Saint-Gobain na Lafarge.
Omuri Shandong Pulisi Chemical, nitwebembeza omutindo, oburinzi n’obuheereza oburikuta omutima aha bakasitoma, turikuha eby’okugarukamu bya oxalic acid ebitebeekanisiibwe kuhikiiriza ebyetaago by’amakorero ebitari bimwe na bimwe omu nsi yoona.
