Sandblasting is Brown corundum One of the main application areas in the industry, because of its moderate hardness, high bulk density, no free silica, significant ratio, good toughness, is an ideal “environmentally friendly” sandblasting material, but most customers have a question that is, can it be used repeatedly?
Brown corundum sandblasting abrasive can be used repeatedly, but the number of repeated use and the material to be sandblasted, brown corundum particle size, hardness and level related, the first grade of grain size sand common specifications 10 mesh, 16 mesh, 20 mesh, 24 mesh, 36 mesh 46 mesh, 60 mesh, 80 mesh, 100 mesh, etc., can be used more than 8 times, the second level is used more than 6 times, the third level can be used more than 3 times, and the other level of brown corundum ash content is very low, very conducive to sandblasting operations.
Of course, different levels of brown corundum not only involve the problem of reuse times, but also manifest in the problem of the size of the on-site sandblasting ash, in today’s more and more attention to environmental protection issues, the use of better quality brown corundum, in order to avoid a large area of dust during sandblasting, while high utilization times can also save costs for enterprises in the long run.
Sandblasting brown corundum can be used to polish scratches, rust, oxidation, deburring, etc. of a variety of metal products, and after polishing, the surface of the metal can look smoother. Stone can be engraved and patterned, and brown corundum can be used for glass and stainless steel and iron plates.
In order to save costs in the early stage, some manufacturers choose brown corundum products that are not very high quality for sandblasting, and the use effect may not be much different, but there may be some problems in environmental protection, and there are fewer times of repeated use, and in the long run, high-quality products will be better and more environmentally friendly.
