How to reduce the loss during sandblasting of white corundum

How to reduce the loss during sandblasting of white corundum
Choice of blasting material
Processing purpose: selected sand
Stainless steel: surface decontamination, slag removal and glass beads with a matt finish
Glass crystal: matt, carved white corundum, brown corundum
Iron products: rust removal, decontamination, deoxidation, coating adhesion, carbon and rust inhibitors
Copper workpiece: glass beads with an oxide-free matte effect
Aluminum parts: descaling, surface enhanced polishing, glass bead lubrication
Electronic components: cleaning and deburring, surface coating, aluminum oxide
sandblasting angle
Many people believe that using a 90° spray gun on the work surface optimizes the rust or decontamination process on the workpiece surface. However, this actually slows down the blasting process and causes the media (grit) to wear out faster. The blasting gun should show the surface of the part to be treated at an angle of 30-45 degrees so that the abrasive can achieve good results with less wear. Especially if you want to find an effect that suits your needs, you will find the balance you want by testing a few angles, make a note, and then create your good spray area based on that standard.
sandblasting line
When sandblasting, close to the machined surface of the part does not give better results and wastes sand. This is because the working distance reduces the size of the blasting area, increases cycle time, and makes it easier to break down the grit, reducing their useful life. The idea is somewhere in between so that your sand wear rate and wear rate are well balanced. Manual inhalation and injection system, 6 to 8 inches. If you are using direct injection system pressure, you should be at 10-14 inches away. Also, keep in mind that no matter what blasting material you use, the closer you get to the thin part, the easier it will be to deform it. In addition to finding the right distance, avoid deformation of the blasted part.
sandblasting material
The secret is to optimize the lifespan of your sand material and your sandblasting, and use the ratio of the sand material. Using too much sand won’t be faster, but your sand will wear out faster. If you use too little, it will reduce efficiency and make it difficult to achieve the desired effect. The amount of sand should be between 50% and 90% of the storage device. Determine the blasting time according to your requirements. Too long is a waste. Depending on the desired effect and the material of the workpiece, choose the right sand material to do the job, and find the right position and angle.
