The reason why the sandblasting machine cannot spray sand during the sandblasting process of silicon carbide?
1. The nozzle of the sandblasting machine does not emit sand: the main reason is that there are foreign objects in the nozzle, which causes the nozzle to be blocked. The use of brown corundum abrasive sandblasting requires regular cleaning of the sandblasting machine, because during the sandblasting process, whether it is the dust carried or its broken small particles, it will be blocked in some gaps due to its small size, which will affect the sandblasting machine. usage of.
2. The impact force of the sand ejected by the sand blasting machine is not enough: if the impact force of the sand ejected is not enough, the brown corundum will always have the grinding force and cannot remove the rust well. The reason for this phenomenon is mostly the spraying The pressure of the sand machine itself is not enough, resulting in a decrease in the momentum of the sand. Generally for sandblasting, the pressure should be greater than 0.7MPa.
In addition, the size of the nozzle will have 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 efficiency of sandblasting. In fact, if you want to obtain a good sandblasting effect, the operator needs to be proficient in the sandblasting operation process, and at the same time have a sufficient understanding of the parameters of sandblasting. In short, whether the sandblasting effect is good or not depends on the quality of the product. The other is to look at the operator’s skills.
