The whole process of sand blasting process of stainless steel plate

We all know that the surface of stainless steel plate is smooth, with high plasticity, strong toughness and strength, corrosion resistance, high temperature resistance and many other characteristics.

Stainless steel sandblasting process is a kind of surface treatment process which uses compressed air as power to blow different abrasives onto the surface of stainless steel plate.

After processing, the surface of stainless steel plate is uniform, the texture is fine, and it has good aesthetics.

Before sandblasting, the surface of stainless steel plate should be treated seriously, which is called sandblasting pretreatment.

Generally, in order to maintain the consistency of appearance, color and other effects of stainless steel plate, 8K mirror treatment is carried out before sandblasting.

Stainless steel plate sandblasting is usually based on glass beads, quartz sand, iron sand, sea sand, diamond and other materials can also be selected.

The higher the number, the smaller the particle size, and the smoother the surface of stainless steel plate after sandblasting. On the contrary, the lower the number of stainless steel plate, the stronger the surface sand feeling. Stainless steel sandblasting is generally used between 30 and 280.

Sand blasting process is to use compressed air as power source to change the spray material into high-speed jet jet jet to the surface of stainless steel plate to be treated, so that the surface of stainless steel plate changes.Because of the impact and cutting effect of abrasive on the surface of stainless steel plate, the surface of stainless steel plate can obtain certain cleanliness and different roughness, and also improve the mechanical properties of stainless steel plate. Therefore, it improves the fatigue resistance of stainless steel plate, increases the adhesion between stainless steel plate and coating, prolongs the durability of stainless steel coating, and also benefits the leveling of coating And decoration.

We know that stainless steel plate is formed on its surface by a very thin and solid stable chromium rich oxide film (protective film), to prevent oxygen atoms continue to penetrate, continue to oxidize, so that stainless steel plate to obtain corrosion resistance.

 However, due to sandblasting is achieved by physical impact, so after sandblasting, stainless steel plate should be passivated to repair the damaged chromium rich oxide film and restore the corrosion resistance of stainless steel!”
