Embodiment 1
[0022] The main steps of the embodiment of the present invention include:
[0023] (1) Pre-treatment, dehumidification and degreasing treatment of die-casting aluminum alloy cookware;
[0024] (2) Paint spraying, the spraying environment temperature is 20°C, the humidity is 70% RH, the spraying method is air spraying, the spray gun diameter is 1.0㎜, and the air pressure is 5-6 Kgf / cm2;
[0025] (3) curing, such as figure 2 As shown, the initial temperature is 60°C, gradually increase the temperature, and reach 160°C after 10 minutes, then keep baking at 160°C for 10 minutes, and finally cool down.
[0026] Before painting, use a 300-mesh or higher mesh filter to avoid particles in the paint film.
[0027] The thickness of the paint film is controlled within 15 μm, and the paint film is easy to crack if it exceeds this thickness.
[0028] During the processing, the surface of the substrate must be kept clean without any dust, oil, etc.
[0029] Step (2) After spraying the ...
