The reason of the densification of the sand - blasted surface was analyzed

　　Sandblasting paint processing can be said to be a process used by most manufacturers. This process can be divided into many kinds. Different fields use different kinds.

　　First, small sand blasting machine in sand blasting paint processing spray gun walking speed is unstable, spray gun walking speed is relatively slow and walking speed is relatively fast, in the unit time of the two ejecta is the same, but the sand distribution area of the former is relatively small, and the latter is relatively large, but because the same amount of sand distribution in different areas of the surface, There will be a dense phenomenon of the nozzle distance from the surface of the workpiece is relatively large, the muzzle from the surface of the workpiece is relatively close, the spray range is relatively small, but the concentration is dense.

　　Two, the air pressure of the sand blasting machine is unstable in the operation process, when the air compressor is used for multiple spray guns, the air pressure is difficult to stabilize, when the air pressure is high, the suction and ejection of sand will be more, when the air pressure is low, it is the opposite, that is, the suction and ejection of sand is less, the ejection of sand is more, the ejection of sand surface is dense, but when the ejection of sand is less, The sand will be thin. When the nozzle of the spray gun is far from the surface of the workpiece, the sand is still so much, but the area of the spray is expanded, and then it will appear sparse.
