Embodiment 1-8
[0052] The plasma generator spray guns with annular plasma flow power of 1000W, 850W, 750W and 650W are used to perform plasma treatment on the concave surface of the curved glass plate, and the surface water droplets on the concave surface after plasma treatment are measured at different distances and moving speeds. contact angles and are reported in Table 1. The distances in Table 1 refer to the distance between the spray gun of the plasma generator and the concave surface of the curved glass plate.

Embodiment 9-10 and comparative example 1
[0057] The power of the annular plasma flow is selected as the plasma generator spray gun of 800W, and the concave surface of the curved glass plate is 10mm away from the plasma treatment, and compared with comparative example 1 using traditional cerium oxide polishing powder polishing, then after plasma treatment and The polished concave surface was coated with a coating, and the coated curved glass plate was subjected to a water boiling test, and the experimental results were recorded in Table 2.
[0058] In Table 2,
[0059] Polishing treatment: 15% mass fraction of cerium oxide aqueous dispersion, polishing treatment with a plane polishing machine;
[0060] Plasma treatment 30mm / s: the power of the annular plasma flow is 800W, the plasma generator spray gun is 10mm away from the concave surface of the curved glass plate, and the moving speed of the annular plasma flow is 30mm / s for plasma treatment;
[0061] Plasma treatment 10mm / s: the power of the annular plasma flow is...
