Embodiment 1
[0024] A surface anticorrosion treatment process for an aluminum alloy plate, comprising the following steps:
[0025] (1) Pretreatment of the aluminum alloy plate: Soak the aluminum alloy plate in the alcohol solution of sodium hydroxide for 35 minutes, take it out and rinse it with clean water, sandblast and remove rust, put it into the acetone solution for ultrasonic cleaning for 50 minutes, and then use deionized Rinse with water and dry at 46°C; among them, the alcohol solution of sodium hydroxide is prepared from sodium hydroxide particles and 68% ethanol solution according to the mass ratio of 1:7. Control it at 5-15mm, control the blasting gas pressure at 0.5-0.8MPa, and control the blasting distance at 10-25cm.
[0026] (2) Arc spraying aluminum: Using an arc spray gun, using the arc as the heat source, heat the linear aluminum wire with a purity ≥ 99.6% to a molten state, and at the same time squeeze the air to blow the molten aluminum wire into a mist to form a rest...
