The XQ69 pre-treatment line is an equipment that performs surface shot blasting and rust removal on steel plates, and applies a layer of protective primer. Pre-treatment of steel can improve its corrosion resistance and fatigue resistance, and prolong its service life; At the same time, it can also improve the surface condition of steel, which is beneficial for CNC cutting machine cutting and precision cutting.
Due to the regular shape of steel plates, it is beneficial for mechanical rust removal and automated painting. Therefore, the use of steel pre-treatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution. Therefore, the pre-treatment process of steel plates has attracted increasing attention from many industries and has been applied in practical production.
The working principle of the steel plate pre-treatment line: The steel plate is transported to blasting chamber through roller conveyor system to remove rust and dirt on the surface of the workpiece. Then, the accumulated shot and floating dust on the surface of the workpiece are blown clean using a roller brush and high-pressure blowing pipe. After rust removal, the steel plate enters the paint spraying room and the primer is sprayed on the surface of the workpiece. Then dry the paint through a drying room and finally send it out of the equipment.
