220 Mesh 2100HV F220 Al2O3 Aluminum Oxide Blasting Media

Brown aluminum oxide blasting media F12 -F220# for coating preparation

• DESCRIPTION

Brown Aluminum Oxide is fused from raw material of calcined bauxite, iron filings and anthracite in an electric arc furnace in 2000℃. And then cooling, crushing into different grit sizes from 4 mesh to 220 mesh usually.

Brown fused aluminum oxide is widely used in abrasives, abrasive blasting, polishing, lapping, and other finishing applications.
In sandblasting, the brown aluminum oxide abrasive can create an exceptionally clean and uniquely etched surface. This unique surface finish is excellent preparation for an application of paint or powder coating.

Brown Aluminum oxide can be used on a variety of materials for surface cleaning and finishing. Such as ferrous metal, steel, Aluminium alloys, Titanium alloy, stainless steel, marble, granite, and stone, etc.

• FEATURES

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. Low loss
The unique size of brown aluminum oxide ensures that more effective particles hit the surface of the object (such as 30-60 mesh sand, which can produce 11 million particles per kilogram to hit the surface of the object, while conventional slag such as 20 mesh can only produce 1 million.

4. 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.

• APPLICATION

Brown aluminium oxide Application -Metal surface preparation before coating

Brown aluminium oxide abrasive media is usually used for blasting pretreatment for variety of materials for preparation before coating. Such as ferrous metal, steel, Aluminium alloys, Titanium alloy, stainless steel, etc.

Sandblasting pretreatment is a very important step in coating preparation. 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 treatment process of surface pretreatment is mainly divided into the following three steps: surface pretreatment, surface purification and surface activation.

Sandblasting is to use brown aluminium oxide abrasive media to increase the surface roughness of the workpieces, and to increase the adhesion between the coating and the workpiece surface. At present, there are many available brown aluminium oxide abrasive specifications for sandblasting pretreatment, such asthe grit size F4#-220#, 0-1mm,1-3mm etc.. The specific abrasive specifications can be selected according to the actual situation.
