Sand blasting is also called sand blowing in some places. Its function is not only to remove rust, but also to remove oil. For workpieces that need to be painted, sand blasting can kill two birds with one stone. So how to solve the problems of brown corundum sandblasting? Then 40% Grinding Xiaobian will give you a detailed introduction.
Sandblasting can be applied in many aspects, such as derusting the surface of parts, modifying the surface of small parts, or sandblasting the joint surface on the steel structure to increase the friction of the joint surface. In short, it is indispensable in industrial sandblasting, and most of the abrasives used in industrial sandblasting are brown corundum abrasives.
This is mainly because the performance of brown fused alumina is relatively strong, and its adaptability is also relatively good, which is suitable for many types of sandblasting machines. However, brown fused alumina will inevitably have some problems during the sandblasting process.
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 sandblasting 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.
