Indlela Yokufaka I-Oxalic Acid ku-Ethylene Glycol Nitric Acid
Le nqubo yokuxilisa ifana kakhulu nendlela yokuxilisa isitashi. Isixazululo se-ethylene glycol esimanzi sishiswa ku-60 °C, bese kuthi i-acid exubile (30%–40% sulfuric acid ngesisindo, 20%–25% nitric acid ngesisindo) kanye ne-vanadium pentoxide kufakwe ngaphansi kokuxutshwa ngamandla. Ukuxilisa kwenziwa ku-50–70 °C kanye no-1.3–4.0 kPa. Umkhiqizo uyapholiswa, uqiniswe, bese uhlungwa ukuze kutholakale i-oxalic acid ehlanzekile engu-99.9% kanye nesivuno esingaphezu kuka-90%. Le ndlela ingenziwa ngaphansi kwezimo ezintathu zenqubo: ingcindezi yomoya, ingcindezi encishisiwe, kanye nengcindezi ekhuphukile. Inenqubo elula, isivuno esiphezulu se-oxalic acid, ikhwalithi enhle yomkhiqizo, kanye nokubuyiselwa cishe okuphelele kwe-nitric acid, kodwa intengo yezinto zokusetshenziswa iphezulu.

I-Shandong Pulisi Chemical Co., Ltd. I-Oxalic Acid Dihydrate – Ibanga Lezimboni 99.6% Ubumsulwa
I-Shandong Pulisi Chemical Co., Ltd., umkhiqizi wamakhemikhali othembekile kanye nomthengisi ongaphandle kusukela ngo-2006, igxile ekukhiqizeni i-oxalic acid dihydrate ehlanzekile kakhulu (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) ngokulawula okuqinile kwekhwalithi. I-oxalic acid yethu yezinga lezimboni ihlanza okungenani u-99.6%, ibonakala njengempuphu emhlophe ekristalu enamazinga aphansi okungcola (i-sulfate ≤0.1%, izinsimbi ezisindayo ≤0.002%, insimbi ≤0.003%). Isetshenziswa kabanzi ekunyatheliseni nasekudayeni izindwangu, ekucubunguleni isikhumba, ekuhlanzeni ubuso bensimbi, ekupholisheni imabula, ekuhlanzweni kwamanzi, ekukhishweni komhlaba ongavamile, kanye nasekuhlanganisweni kwemithi okuphakathi.
Sigcina impahla enkulu ekhona esitokweni sethu sokugcina impahla saseShandong, okwenza sikwazi ukuthunyelwa ngokushesha kwama-oda amaningi. Izinketho zokupakisha eziguquguqukayo (izikhwama ezingama-25kg, ezingama-50kg, ezingama-1000kg) kanye nokuthunyelwa komhlaba wonke okuvela emachwebeni aseQingdao, eTianjin, noma eShanghai kuqinisekisa ukulethwa ngesikhathi emhlabeni jikelele. Sinikeza ukwesekwa okugcwele kwezobuchwepheshe, imibhalo ye-COA/MSDS, kanye namanani okuncintisana ukuze kuhlangatshezwane nezidingo ezahlukene zezimboni.
Xhumana nathi namuhla ukuze uthole isilinganiso esenziwe ngokwezifiso futhi uvikele uchungechunge lwakho lokuhlinzeka nge-oxalic acid.
