Embodiment 1
[0049] Preparation of dust-proofing agent
[0050] Step 1. Dissolve 1% perfluorosilane and 2% silane coupling agent in 97% absolute ethanol in proportion, then stir for 40 minutes at a speed of 4000 r / min, and then ultrasonically treat for 10 minutes, and the ultrasonic frequency is 60KHz. Get dust repellant.
[0051] Processing aluminum sheet (pure aluminum sheet)
[0052] S1: The surface of the aluminum sheet is first subjected to mechanical polishing treatment. After that, the mechanically polished aluminum sheet is used as the anode, and the metal copper is used as the cathode. The two electrodes are immersed in a 0.15mol / L sodium chloride solution in the electrolytic cell at the same time, and the direct current is applied. , at 2A / cm 2 Under the current density of 360S, the polished aluminum sheet was obtained by etching for 360S.
[0053] After testing, the surface roughness of the polished aluminum sheet was 20nm. It was dipped in a dust-proof agent, left standing f...
