Passivated aluminum powder production equipment and method

Abstract

The invention relates to passivated aluminum powder production equipment and method, and relates to the field of chemical equipment. The passivated aluminum powder production equipment comprises an atomizing chamber, a balance tank and a humidifier arranged on the balance tank, wherein the atomizing chamber is connected to the balance tank through a pipeline, the passivated aluminum powder production equipment further comprises a PLC control module, a humidification feedback module, a temperature control module and a valve control assembly, wherein the humidification feedback module, the temperature control module and the valve control assembly are connected to the PLC control module, the signal output end of the PLC control module is connected to a production system PLC. and the passivated aluminum powder production equipment further comprises a method for producing the passivated aluminum powder by applying the production equipment. According to the passivated aluminum powder production equipment, a passivated aluminum powder product with high safety performance can be obtained, the dangerous characteristic of common aluminum powder is avoided, the passivated aluminum powder product can be stored, transported and put into use according to common goods, and the cost is saved while the safety performance is improved.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a passivated aluminum powder production equipment and method. Background technique [0002] Micro-spherical aluminum powder is made by spraying aluminum in high-pressure gas in a molten state. The appearance is silver-gray, and the particles are relatively regular spherical or drop-shaped. long-term storage. However, fine spherical aluminum powder belongs to hazardous chemicals, and has strict requirements on storage and transportation. When it is put into use as a raw material, the production workshop needs to be an explosion-proof workshop, which seriously limits its application scope. The passivation aluminum powder is of great significance; [0003] The invention patent with the application number CN201310119933.8 discloses a preparation process and device of ultra-fine high-activity aluminum powder. In this preparation process, the aluminum ingots are first m...

AI Technical Summary

Problems solved by technology

[0005]The disadvantages of the above preparation processes are: using aluminum ingots to melt into molten aluminum and then atomizing production, which consumes more energy; The safety of production and subsequent storage and use is ignored, and it is also exposed to air when it is produced and discharged, and it is also exposed to air during storage and downstream use. It will increase to more than 3nm in the future; and at present, domestic manufacturers generally make ordinary aluminum powder, which belongs to hazardous chemicals, and the storage and transportation costs are relatively high. The production workshop when it is used as raw material must be an explosion-proof workshop, and the production cost is high
