Embodiment 1
[0051] A high-reliability and environment-friendly galvanizing process for electric power fittings, comprising the following process steps:
[0052] a. Prepare materials; stack them according to the size and shape of the workpieces, and inspect the workpieces;
[0053] B. Shot blasting: the product of step a is put into a shot blasting machine, and the mixed steel shot in the shot blasting machine is projected onto the surface of the hot-plated workpiece to be decontaminated, and the impact makes the pollutants on the surface of the hot-plated workpiece to be decontaminated be stripped off; The blasting time of the workpiece by the shot blasting machine is set according to the surface area of the workpiece. The blasting time of the workpiece with a surface area of 0.15-0.20min per square centimeter, for example, the workpiece with a surface area of 340 square centimeters, the blasting time is 51-68min.
