Method Guide for Selection of Abrasive Materials:

There are many varieties of grinding materials, mainly steel sand, steel shot, quartz sand, brown corundum, copper ore, glass sand, walnut shell, aluminum shot and so on. According to the substrate and requirements, choose abrasive. In principle, it is a good method to choose the grinding wheel with the same material as the substrate. Under a certain pressure, the higher the hardness of the grinding wheel, the higher the cleaning efficiency. The smaller the particles of the grinding wheel, the higher the efficiency. The pressure blasting machine Chinese medicine gun hole between 6-12mm, the larger the abrasive particles, the higher the amount of particles from the sand gun aperture, the less the number of points per unit area impact workpiece surface, the lower the efficiency of blasting. On the contrary, the smaller the abrasive particles, the more the number of particles out of the gun aperture, the more points per unit hit the workpiece surface, the higher the blasting efficiency. However, if the particle size of the abrasive is less than 0.05MM, just like dust, the kinetic energy of impact on the surface of the workpiece is small, there is no power, and the efficiency is not high. Turn on the power check, check whether it works normally, the total time required to stop the exhaust, check whether the sealing ring of the closed valve is aging or broken, when this happens, it should be replaced immediately.

1, look at the size of the workpiece, choose the box type sandblasting machine, mobile sandblasting machine, automatic sandblasting machine.

2. To see the shape of the product, choose the specifications of the sandblasting machine. Generally, there are certain specifications below one meter, especially for large orders or open.

3, the level of requirements for the product surface, specifically, is to use dry spray or wet spray, if it is dry spray, there are many choices of abrasive, wet spray is usually glass sand, etc.

4. Some accessories of sandblasting machine should be familiar with. Spray guns and gun gloves are often replaced because the sandblasting actually wears a lot.
