Umsebenzi
I-oxalic acidIsixazululo esijwayelekile yisixazululo se-oxalic acid ngohlu lokuhlushwa olunembile owaziwayo futhi lusetshenziswa kabanzi emikhakheni efana nokuhlaziywa kwamakhemikhali, ukukhiqizwa kwezimboni, kanye nocwaningo lwesayensi. Izindlela zohlelo lokusebenza main zimi ngalendlela elandelayo:
Ukuhlaziywa kwamakhemikhali nokuzimisela
- I-Acid - Isisekelo sokuThombisa: I-Oxalic Acid iyi-acid ebuthakathaka ye-dibasic engabhekana nokusabela kokungathathi hlangothi ngezisekelo. Ingasetshenziswa njengesixazululo esijwayelekile se-acid ukunquma ukugxila kokungaziwa - Isixazululo se-Alkaline Solution. Isibonelo, lapho kukhipha isisombululo se-sodium hydroxide ngesisombululo esijwayelekile se-oxalic acid, kusetshenziswa inkomba, ukugcwaliswa okunembile kwesisombululo se-sodium hydroxide kungaba kususelwa ebudlelwaneni be-stoichiometric kanye nenani lekhambi le-oxalic acid acid elisetshenziswe ekugcineni - iphuzu lokutholwa.
- Ukutholwa kabusha kwe-Redox: Into yekhabhoni e-oxalic acid ine-aulic ka +3, ekhombisa ukushesha futhi ukwazi ukusabela ngezinto eziqinile zoxesing ekuphenduleni kabusha. Kwi-acidic medium, i-sodium oxalate ingaba oxidised yi-potanganum permanganate. Ngokusebenzisa lokhu kusabela, isixazululo esijwayelekile se-oxalic acid singasetshenziselwa ukukala ukugxila okunembile kwesisombululo se-potassium permanganate.
Ukulawulwa Kwekhwalithi Yezimboni
- Ukwelashwa okungaphezulu kwensimbi: Ezinhlelweni zokwelashwa ezingaphezulu kwezinsimbi ezinjenge-aluminium, izixazululo ze-oxlic acid zingasetshenziselwa ukucwilisa nokuhlanza. Ngokusebenzisa isixazululo esijwayelekile se-oxalic acid, ukugxila kwesixazululo kungalawulwa ngokunembile ukuqinisekisa ukuvumelana nokuqina komphumela wokwelashwa kwensimbi, ngaleyo ndlela kuthuthukisa ikhwalithi yomkhiqizo. Isibonelo, ngokulawula ukufinyeleleka kwesisombululo esijwayelekile se-oxalic acid ngaphakathi kwebanga elithile, umkhiqizo we-aluminium ungafakwa ukuze uthole ukufakwa komfaniswano nokuhle komhlaba.
- Imboni ye-electroplating: Isixazululo esijwayelekile se-oxalic acid singasetshenziswa ukulungisa i-acidity nokwakhiwa kwesisombululo se-electroplating, kuqinisekisa ikhwalithi nokusebenza kwesendlalelo se-electroplated. Ukulawula ngokunembile okuhlushwa i-oxalic acid kusiza ukuthuthukisa ukunamathela, isicwebezelisi, kanye nokuphikiswa kokugqwala kwesendlalelo se-electroplated, ukuqinisekisa ukuthi imikhiqizo ye-elektroplated ihlangabezana namazinga ekhwalithi.
Ukupakisha nokuthumela
I-25KG / DRUM noma njengezidingo zamakhasimende.
Ukuthumela: Izinhlobo eziyi-6 zezimpahla eziyingozi futhi zingahambisa ngo-Ocean.
Gcina futhi ugcine
I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.
