Mfundo Zoyambira Zosungunulira Mayankho a Oxalic Acid
Kapangidwe ka mankhwala a oxalic acid (ethanedioic acid) kamafunikira kuwongolera bwino kuchuluka kwa kusungunuka kwa madzi. Oxalic acid yogulitsa nthawi zambiri imapezeka m'mitundu iwiri: ufa wa kristalo ndi mayankho okonzedwa kale. Ufa wa kristalo uli ndi chiyero chapamwamba (nthawi zambiri ≥99%) ndipo uyenera kukonzedwa kuyambira pachiyambi, pomwe 30%-50% mayankho osakanikirana kale amafunikira kusungunuka kwachiwiri.
Pa ufa wa crystalline oxalic acid, chiŵerengero chotetezeka cha muyezo ndi magalamu 15–25 a ufa pa magalamu 100 a madzi, zomwe zikugwirizana ndi kuchuluka kwa pafupifupi 13%–20%. Kuchuluka kumeneku kumatsimikizira kuti zinthu zodetsa monga dzimbiri ndi limescale zimawonongeka bwino pamene zikupewa dzimbiri ku zinthu zambiri. Deta yoyesera ikuwonetsa kuti pamene kuchuluka kwa dzimbiri kupitirira 25%, chiŵerengero cha dzimbiri pa chitsulo chosapanga dzimbiri chimawonjezeka kwambiri.
Mayankho okonzedwa kale ayenera kuchepetsedwa pogwiritsa ntchito njira yolunjika. Yankho la 30% la stock limalimbikitsidwa kuti lichepetsedwe pa chiŵerengero cha 1:5 mpaka 1:10 (yankho la stock: madzi) kuti mupeze yankho logwira ntchito la 3%–5%. Yankho la 50% la stock liyenera kuchepetsedwa pa 1:10 mpaka 1:20 kuti mupeze kuchuluka koyenera kwa 2.5%–5%. Kusungunuka kumeneku kumaonetsetsa kuti yankholo limakhalabe lofanana komanso lokhazikika, kuletsa kuchulukana kwambiri komwe kulipo.
Zibo Anhao Chemical Co., Ltd. – Oxalic Acid
Zibo Anhao Chemical Co., Ltd. ndi kampani yodalirika yogulitsa oxalic acid yoyera kwambiri (CAS 144-62-7), yomwe imadziwikanso kuti ethanedioic acid, yokhala ndi formula ya molekyulu C₂H₂O₄. Monga dicarboxylic acid yosavuta, imawoneka ngati yoyera, yopanda fungo, yosungunuka m'madzi ndi ethanol, yokhala ndi acidic yamphamvu komanso yabwino kwambiri yoyeretsera. Katundu wathu amapezeka mu mitundu yonse ya anhydrous ndi dihydrate, kutsatira malamulo okhwima a mafakitale ndi apamwamba kuti atsimikizire kuyera kwa ≥99.6% komanso magwiridwe antchito okhazikika.
Oxalic acid ndi chinthu chogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Pakukonza zitsulo, imagwira ntchito ngati chochotsera dzimbiri, chotsukira mamba, komanso chotsukira pamwamba pa zitsulo, komanso chochotsa bwino chitsulo ndi ma ayoni ena achitsulo. Mumakampani opanga nsalu ndi zikopa, imagwiritsidwa ntchito poyeretsa, kupukuta utoto, komanso kuchotsa zinthu zina. Imagwiranso ntchito yofunika kwambiri pakuchotsa nthaka yachilendo, kuyeretsa ceramic, kupanga mankhwala, komanso kupanga mchere wa oxalate monga cobalt oxalate ndi lithium oxalate. Kuphatikiza apo, imagwira ntchito ngati chotsukira zipangizo zomangira komanso chotsukira matabwa mumakampani opanga mipando.
Ku Zibo Anhao Chemical, timaika patsogolo kuwongolera khalidwe ndi kupanga zinthu mokhazikika. Oxalic acid yathu imapangidwa motsatira njira zokhazikika komanso mayeso okhwima pagawo lililonse, mogwirizana ndi miyezo ya ISO ndi mafakitale apadziko lonse lapansi. Timapereka njira zosinthira zolongedza, kuphatikiza matumba olukidwa apulasitiki okwana 25kg ndi ng'oma za 50kg, kuonetsetsa kuti malo osungira ndi kunyamula zinthu ndi otetezeka. Ndi luso lolimba la unyolo woperekera zinthu komanso zaka zambiri zokumana nazo zotumiza kunja, timapereka zinthu zokhazikika, mitengo yampikisano, komanso chithandizo chaukadaulo chodzipereka kwa makasitomala apadziko lonse lapansi, ndikulimbikitsa mgwirizano wodalirika komanso wanthawi yayitali.
