Description

Technical Field

[0001] The utility model relates to the technical field of expanded graphite production, in particular to automatic preparation equipment for an acidic oxidant. Background Art

[0002] In the production process of expanded graphite, it is necessary to use an intercalation agent to intercalate flake graphite. The intercalation agent generally uses acidic oxidants such as sulfuric acid, sodium vanadium red, and hydrogen peroxide. The intercalation agent needs to be prepared before use. Taking hydrogen peroxide as an example, since hydrogen peroxide will accelerate decomposition when exposed to heat or light, an appropriate amount of stabilizer (such as sodium stannate, sodium pyrophosphate, ethanol, etc.) is added in actual use to improve its chemical stability.

[0003] Hydrogen peroxide is weakly acidic, has a pungent odor, and can cause cancer. Protective clothing must be worn when working with it, otherwise it will cause dermatitis, bronchial and lung diseases. Therefore, special care must be taken when preparing it, and the mixing speed of various raw materials must be strictly controlled. At present, in the production process of enterprises, manual mixing is generally used, which not only has low mixing efficiency, but also has certain risks in the process of adding materials and stirring, so it needs to be improved.
