Embodiment 3

[0038] The application method of embodiment 3 titanium nano-polymer alloy coating material

[0039] ①Surface treatment: Use a small-caliber pipe shot blasting machine to perform sandblasting or shot blasting on the inner and outer walls of the steel pipe. The weight control must meet the national standard of Sa2.5, so that the surface of the steel pipe is free of rust and scale, and the steel color is exposed.

[0040] ② In-pipe primer coating: use a high-pressure airless sprayer to coat a primer with a wet film thickness of about 100 μm, enter the oven for flash drying, and control the oven temperature at 100-120°C and leave the oven for 10-15 minutes. The paint film is no longer sticky and has a certain strength, but it is not cured;

[0041] ③ "Wet-on-wet" topcoat coating: Use a pipeline inner coating machine to spray a topcoat with high-pressure airless spraying. The wet film thickness is controlled at 120-150 μm, and it is dried in an oven. After 20 minutes out of the ov...
