Brown Fused Aluminum Oxide F100

How to solve the problem of poor Brown alumina sandblasting and rust removal ?

1. Choose the appropriate sandblasting material: Different sandblasting materials have different hardness and intensity. Choosing the appropriate material can improve the rust removal effect. Generally speaking, aluminum oxide sand, silicon carbide, Zirconia alumina and glass beads sand are suitable for light rust removal, while steel sand and iron sand are suitable for heavy rust removal.

2. Adjust the sandblasting pressure and sandblasting distance: Sandblasting pressure and sandblasting distance have a great impact on the rust removal effect. If the blasting pressure is too low or the blasting distance is too far, the rust layer may not be completely removed. The sandblasting pressure can be appropriately increased or the sandblasting distance can be reduced to improve the rust removal effect.

3. Sandblasting angle and sandblasting speed: Sandblasting angle and sandblasting speed will also affect the rust removal effect. Generally speaking, sandblasting at an angle perpendicular to the surface of the object to be rusted can better remove the rust layer. In addition, appropriately increasing the sandblasting speed can also improve the rust removal effect.

4. Clean the surface of the object to be rusted: Before sand blasting and rust removal, the surface of the object to be rusted should be cleaned to remove oil and impurities on the surface. This improves the effectiveness of sandblasting rust removal and reduces the possibility of rust layer regeneration.

5. Use chemical rust remover to assist: If the sandblasting rust removal effect is still not good, you can consider using chemical rust remover to assist. Chemical rust removers can dissolve the rust layer, making sandblasting and rust removal more thorough. However, it should be noted that when using chemical rust removers, you must pay attention to safe operations to avoid harm to the environment and human body.

In short, to solve the problem of poor sandblasting rust removal effect, it is necessary to comprehensively consider factors such as sandblasting material, sandblasting pressure, sandblasting distance, sandblasting angle, sandblasting speed, etc., and appropriate use of chemical rust removers for assistance. By adjusting these factors, the effect of sandblasting and rust removal can be improved and better rust removal results can be achieved.
