Embodiment 1
[0013] (1) In the φ800×1000 vertical stirring ball mill, put 500kg of glass balls with a diameter of 1.0-5.0mm, add 100kg of D50 solvent oil, D 50 40kg of 7.8μm nitrogen atomized fine spherical aluminum powder and 4kg of oleic acid were ball milled for 48 hours at a speed of 50-200 rpm, discharged, filtered, and the filtrate was returned to the ball milling process for recycling.
[0014] (2) The filter cake enters the screening and grading process, first passes through a 120-mesh sieve, and then passes through a 500-mesh sieve. The materials at all levels of screening are filtered with a filter press, dried, and then fresh D 50 Washing with organic solvents; the filtrate is returned to the screening process for recycling.
[0015] (3) The filter cake enters the kneading process for surface treatment, and the packaging becomes a strong flashing aluminum silver paste product.
Embodiment 2
[0017] (1) In the φ800×1000 vertical stirring ball mill, put 500kg of glass balls with a diameter of 1.0-5.0mm, add 200kg of D80 solvent oil, D 50 80kg of nitrogen atomized fine spherical aluminum powder of 7.8μm, 4kg of oleic acid, ball milled for 38 hours at a speed of 50-200 rpm, discharged, filtered, and the filtrate returned to the ball milling process for recycling;
[0018] (2) The filter cake enters the screening and grading process, first passes through a 120-mesh sieve, and then passes through a 500-mesh sieve, presses the materials at all levels of screening with a filter press, blows them dry, and washes them with fresh organic solvents; the filtrate returns to the sieve Recycling by process;
[0019] (3) The filter cake enters the kneading process for surface treatment, and the packaging becomes a strong flashing aluminum silver paste product.
