Problems solved by technology
The fluoride solution contains highly harmful poisonous hydrofluoric acid, its chemical properties are very unstable, and there are great safety hazards for storage and on-site operation; while the salt solution produces a large amount of hydrogen in the process of dissolving magnesium powder and magnesium chips, introducing and the raw material price used by the two methods is more expensive, and the cost is higher when processing magnesium powder and magnesium chips in industry
Due to the small size of magnesium powder and magnesium shavings in the casting remelting method, it is easy to violently oxidize and burn during feeding and is difficult to control, so the safety risk is greater

Abstract
The invention relates to a processing method for magnesium alloy powder chips, and discloses a safe processing method for magnesium powder and magnesium chips generated in industrial production. Specifically: mix magnesium powder and magnesium chips with graphite powder particles, then put them into a bleach solution at a certain temperature, conduct electrification and ultrasonic pretreatment on them, and then dissolve under electrification conditions to convert magnesium into magnesium ions, and then put A certain amount of lime water is added to this solution, and the reaction produces Mg(OH) 2 precipitation. The invention converts the magnesium powder and magnesium chips produced in the production into Mg(OH) 2 Precipitation eliminates the risk of ignition and explosion of magnesium powder and magnesium chips; at the same time, the cost of raw materials such as bleaching powder and lime water is low, and the materials are widely used, which is suitable for industrial promotion and application.
Description
technical field [0001] The invention relates to a processing method for magnesium powder chips, in particular to a safe processing method for magnesium powder and magnesium chips generated in industrial production. Background technique [0002] Magnesium powder and magnesium chips in industrial production are more harmful to human health and production safety. The specific surface area of magnesium powder and magnesium chips is relatively large, and the chemical activity is relatively high. It is easy to oxidize and exothermic when exposed to the air, but the heat is not easy to dissipate after the magnesium powder and magnesium chips are gathered. When the temperature rises to the ignition point, it will burn It may even explode, which poses a great threat to the safety of the production site; if the storage environment of magnesium chips and magnesium powder is humid or there is water, the air will contain certain reaction-generated H 2 , if the temperature rises to the...
