Advantages of garnet sand used in sandblasting and rust removal
Rust is a loose, porous, and constantly expanding substance. Rust is more common in our daily lives. Generally, the main method of removing rust is sandblasting. If sandblasting is not carried out for a long time, it will cause the rust to expand very much, thereby deforming the coating surface, resulting in tiny cracks and accelerating the entry of water and corrosion particles, which greatly affects the anti-corrosion effect of the paint film, and also leads to steel The service life is greatly reduced.
Advantages of garnet sand used in sandblasting and rust removal
In recent years, garnet sand has been used more and more widely, and it has gradually replaced traditional abrasives for sandblasting and rust removal. The characteristics of garnet sand are very good, not only does not contain free silicon and harmful heavy metals, but also has high hardness, second only to topaz and corundum, and very good toughness. The broken rate is low and can be recycled many times, so the cost of use is reduced.
Compared to the quartz sand used for sandblasting and rust removal in the past. Copper slag and river sand, etc., these materials are easily broken during sandblasting and rust removal, which will greatly reduce the efficiency of sandblasting and increase the cost of use. The cleaning effect of garnet sand is very good, and there will be no dusty phenomenon during operation, and it will not cause harm to human body.
