Steel rust blasting structure and surface quality of the compressed air pressure, nozzle flow, private residence time and other factors. Compressed air pressure is bigger, greater private velocity, greater inspection, derusting quality requirements the shorter time; nozzle stay longer, more high quality, rust.
After sand blasting surface is uniform and the main polish, polishing sand hardness, expansion and injection technology and other factors. The hardness of iron, not much, coarse, blood big home. Comparison of the hardness of the quartz sand. After crushing, many corners of the corner, the size distribution is uniform, through the quartz sand. The use of sand surface rust, really good home.
The influence of injection process parameters of surface polishing the main air pressure, nozzle diameter, spray angle, distance etc.. Compressed air pressure, nozzle diameter, sand like momentum immediately with the recoil of the bearing ability of the pressure hose and other equipment and I UHV operators consider the, compressed air pressure and nozzle diameter must be controlled. Spraying distance, jet angle is not melting arrived effect and derusting quality also has a great influence and of spray distance is small, private impulse large area, and private, small and large density function is to eliminate melt improves the efficiency to complete the spray angle is 45 DEG; production of the roughness maximum.
It is worth noting that the pressure of compressed air is very large, time and distance are wasted, increasing the degree of damage to private private, and reduce the increase in the pressure of air pressure and the increase of the distance of the spread is very low.
