1. The nozzle of the sandblasting machine does not produce sand: the primary reason is that there is foreign matter in the nozzle, resulting in the nozzle blockage. When using abrasives for sandblasting, it is necessary to clean the sandblasting machine punctually, because of the small size of sandblasting, the dust and broken small particles will be blocked in some gaps, affecting the use of sandblasting machine.
2. The impact of sandblasting machine is not good: assuming that the impact force of sand blasting is not good, brown corundum always has grinding power and cannot remove rust spots well. The primary reason for this phenomenon is that the pressure of the sandblasting machine itself is not good, resulting in a decrease in the amount of sanding. Generally speaking, the pressure of sandblasting should be greater than 0.7 MPa In addition, the scale of the nozzle has a certain impact on the pressure, that is, the smaller the nozzle, the greater the pressure, but the nozzle should not be too small, because too small will affect the sandblasting power.
In fact, in order to achieve excellent sandblasting results, operators need to grasp the blasting operation process and have a satisfactory understanding of the blasting parameters. In short, the quality of the sandblasting effect depends on the quality of the product and on the other hand, on the skill of the operator.
