Brown aluminium oxide blasting media F12#-F220# for hot dip galvanizing pretreatment
Brown aluminium oxide abrasive are usually used for sandblasting because of its angular shape, good hardness and good toughness. Its purpose is to make the workpiece have a certain bonding surface through brown aluminium oxide sandblasting.
Brown aluminium oxide sandblasting pretreatment is usually a very important step in the preparation of the coating. The surface quality of the processed workpiece will directly affect the bonding strength of the surface and the coating, thereby affecting its service life.

The pretreatment of hot-dip galvanizing process adopts pickling and phosphating processes. There will be acid and alkali residues on the surface of the workpiece, making the hot-dip galvanizing layer easy to fall off. In the Zinc spray, aluminum spray process, the pretreatment adopts the sandblasting process with brown aluminium oxide abrasive media.
The Brown aluminium oxide grits are of angular shape, good hardness and good toughness.
After sandblasting, the surface of the workpiece is very clean and rough, with sa≥2.5, good coating adhesion, and tensile strength≥0.6kg/mm2.
After the surface is sprayed with zinc and aluminum, there will be no corrosion from the inside to the outside, so that the zinc layer will not fall off.
As sandblasting abrasive media
1. Less dust
Due to brown aluminum oxide’s relatively high specific gravity, it produces less dust during the sandblasting process. This ensures operator health and safety and improves operator visibility.
2. High efficiency
The brown aluminum oxide abrasive grits can quickly hit the surface of the object with sharp edges and corners, it is regarded as a very fast way of sandblasting.
3. High surface treatment quality
During the blasting process, brown aluminum oxide can penetrate deep into the caves and pits of the surface to reach the bare surface of the metal, so it can completely remove all rust, water-soluble salts and other pollutants.
