Method for separating nanometer aluminum powder with different particle sizes

[0007] Although these methods have good separation effects, the separation equipment is bulky and expensive, and the separation proc...

The inventor finds that the method of ultrasonic vibration is used to assist the dispersion of nano-aluminum powder in dispersant, which can effectively break the agglomeration of nano-aluminum powder, so that nano-aluminum powder is evenly dispersed in dispersant, and the longer the time of ultrasonic vibration is The longer the time, the better the dispersion effect, but if the time of ultrasonic vibration is too long, the dispersant will volatilize in large quantities, which will reduce the dispersion effect. Therefore, the present invention preferably uses the method of ultrasonic vibration to assist the dispersion of nano aluminum powder. The time is 2 to 6 hours, preferably 3 to 5 hours, such as 4 hours.

The inventors have found that the above-mentioned aluminum paste containing a large amount of aluminum dust is disposed of as waste, which not only causes a waste of resource...
