Njira Yokonzekera Yokhazikika ya Oxalic Acid
Njira yokonzekera yankho iyenera kutsatira mosamalitsa njira zoyesera mankhwala. Choyamba, sankhani zidebe zopangidwa ndi polyethylene yapamwamba kwambiri (HDPE), yomwe imapereka kukana kwabwino kwa oxalic acid poyerekeza ndi pulasitiki wamba. Zidebe zagalasi zitha kugwiritsidwa ntchito kwakanthawi kochepa, koma kusungidwa kwa nthawi yayitali kungayambitse kutuluka kwa sodium ion, zomwe zimakhudza kukhazikika kwa yankho.
Mukakonzekera, nthawi zonse yesani kuchuluka kwa madzi kofunikira kaye, kenako pang'onopang'ono tsanulirani oxalic acid m'mbali mwa chidebecho. Dongosolo ili siliyenera kusinthidwa. Mayesero akusonyeza kuti kuwonjezera madzi ku asidi wokhuthala kumayambitsa kusintha kwa exothermic nthawi yomweyo kufika madigiri 80–100°C, zomwe zingayambitse ngozi zothira madzi. Kutsatira ndondomeko yoyenera kumasunga kutentha mkati mwa malo otetezeka.
Pofuna kusakaniza, gwiritsani ntchito galasi kapena polytetrafluoroethylene (PTFE) stir bar, ndipo sakanizani mosalekeza kwa mphindi 5-7 mpaka yankho litamveka bwino. Dziwani kuti kusungunuka kwa oxalic acid ndi njira yochokera ku endothermic. Lolani yankho lokonzedwa liyime kwa mphindi 20-30 kuti lifike kutentha kwa chipinda, pomwe pH idzakhazikika pamlingo woyenera wa 1.5-2.0.
Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ndi kampani yodalirika komanso yogulitsa oxalic acid (ethanedioic acid, CAS 144‑62‑7) yomwe ili ndi likulu lake ku Zibo, Shandong, China. Oxalic acid yathu imapezeka mu mitundu yonse ya anhydrous (C₂H₂O₄, MW 90.03) ndi dihydrate (H₂C₂O₄·2H₂O, MW 126.07), yokhala ndi chiyero chochepa cha 99.6%. Imawoneka ngati makhiristo owonekera opanda mtundu kapena ufa woyera wa kristalo, ndi yopanda fungo, ndipo imasungunuka kwambiri m'madzi ndi ethanol.
Yopangidwa motsatira njira zowongolera khalidwe komanso ISO 9001, oxalic acid yathu imakwaniritsa miyezo ya mafakitale ndi reagent yokhala ndi zodetsa zochepa (Cl⁻ ≤0.005%, SO₄²⁻ ≤0.10%, Fe ≤0.05%). Monga dicarboxylic acid yogwiritsidwa ntchito mosiyanasiyana komanso chochepetsera, imagwira ntchito ngati chothandizira kwambiri pa chelating, bleaching, komanso mankhwala. Imagwiritsidwa ntchito kwambiri pochiza pamwamba pa chitsulo (kuchotsa dzimbiri, kusuntha), utoto ndi kusindikiza nsalu (mordant, bleach), kupukuta khungu, kupukuta marble, ndi kuchiza madzi. Ndikofunikanso kwambiri pakuchotsa zinthu zachilendo zapadziko lapansi, kupanga organic (oxalate salts/esters), mankhwala ophatikizana, ndi mankhwala oyeretsera.
Ku Anhao Chemical, timaonetsetsa kuti zinthu zambiri zikupezeka bwino, kuyang'anitsitsa bwino zinthu, komanso kulongedza zinthu mosinthasintha: matumba 25kg, 500kg/1000kg FIBC, ndi matanki a ISO. Ndi zaka zambiri zogwira ntchito yopanga mankhwala ndi kutumiza kunja, timapereka oxalic acid kwa makasitomala ku Southeast Asia, Europe, Middle East, ndi kwina, mothandizidwa ndi chithandizo chaukadaulo komanso njira zoyendetsera zinthu bwino. Tadzipereka kupereka mayankho a oxalic acid apamwamba komanso otsika mtengo omwe amagwirizana ndi zosowa zanu zamafakitale ndi zamalonda.
