Influencing factors in all aspects of sandblasting machine

The sandblasting machine uses compressed air to flow in the spray gun at high speed to form negative pressure to produce the ejection effect. The abrasive in the cyclone storage tank is sucked into the spray gun through the sand pipe, and then it is shot to the surface of the workpiece from the nozzle at high speed along with the compressed air flow. To achieve the purpose of sandblasting. In the working state, compressed air and sand are sprayed while mixing, so that the compressed air can be fully utilized. The air flow and sand flow are easy to adjust, and an ideal mixing ratio can be obtained. Energy and sand consumption are low, and the cleaning efficiency is high. .

        Influencing factors in all aspects of sandblasting machine:

        1. The influence of the type of abrasive on the surface result

        Abrasives are divided into spherical and rhombic according to the state of their particles. Diamond abrasives (white steel jade, brown corundum) usually used for sandblasting are diamond-shaped abrasives. The glass beads are spherical abrasives. After setting the three values of P, H and θ, the surface result obtained by spherical abrasive sandblasting is smoother, while the surface obtained by diamond abrasive material is relatively rough, and the same kind of abrasive material is divided into thickness and fineness. In China, the abrasive material is divided according to the number of screens. The thickness of the abrasive is generally called the number. The higher the number, the smaller the particle size. After the P, H, and θ values are set, the higher the number of the same abrasive blasting, the smoother the surface result will be.

        2. The effect of pressure adjustment on the surface results

        After setting the three quantities of S, H and θ, the larger the value of P, the higher the speed of the jet, the higher the efficiency of sandblasting, and the rougher the surface of the workpiece. On the contrary, the surface is relatively smooth.

        3. The influence of the distance and angle of the spray gun on the surface results

        After the P and S values are set, this item is the key to manual sandblasting technology. The distance between the spray gun and the workpiece is generally 50-150mm. The farther the spray gun is from the workpiece, the lower the efficiency of the jet stream and the smoother the surface of the workpiece. The smaller the angle between the spray gun and the workpiece, the lower the efficiency of the jet stream and the smoother the surface of the workpiece.
