Embodiment 1
[0027]Preparation of paint: Take 150 grams of silicon dioxide, 100 grams of phosphorus pentoxide, 75 grams of aluminum oxide, 32.5 grams of sodium carbonate, 6 grams of potassium carbonate, 50 grams of calcium fluoride, 25 grams of boron oxide, 3 grams of nickel monoxide, 8.5 gram of cobalt monoxide, mixed evenly, and ground to make the powder through a 200-mesh sieve; get 25 grams of basalt fiber (diameter 1-2 micron, length 20-50 micron) and 25 gram of aluminum silicate fiber (diameter 1-2 micron , length 20-50 microns) into the sieved powder, mix evenly, set aside.
[0028] Substrate treatment: use sandblasting to remove rust and dirt on the surface of the steel bar, and dry it for later use; the steel bar is a HRB600 threaded steel bar with a strain of less than or equal to 2800 microstrains during use.
[0029] Coating: Ground the treated steel bar, and use an electrostatic spray gun to evenly coat the powder on the surface of the steel bar. The electrostatic voltage is 6...
