[China Glass Net] There are many varieties of abrasives, mainly including: steel sand, steel shot, quartz sand, brown corundum, copper ore, glass sand, walnut shell, aluminum shot and so on. Different abrasives should be selected according to different substrates and different requirements. In principle, it is better to use the same material as the substrate. Under certain pressure, the higher the hardness of the abrasive, the higher the cleaning efficiency; the smaller the abrasive particles and the higher the efficiency. Since the inner hole of the medium-made medicine sand gun of the pressure-feeding type blasting machine is between 6-12MM, the larger the abrasive particles, the smaller the amount of particles passing through the aperture of the blasting gun, and the more points per unit area hitting the surface of the workpiece. Less, the efficiency of sand blasting is low. Conversely, the smaller the abrasive particles, the more particles are discharged through the aperture of the blasting gun, and the more points that hit the surface of the workpiece in the unit, the higher the blasting efficiency. However, if the diameter of the abrasive particles is less than 0.05 mm, it is like dust, and the kinetic energy hitting the surface of the workpiece is small, there is no power, and the efficiency is not high.
