Garnet sandblasting is widely used for rust removal
Rust is a porous and loose substance, which is very common in life. Among them, the most common method of rust removal is sandblasting. If the iron is not sandblasted in excess, it will cause the iron matrix to deform due to the development and expansion of rust, resulting in rupture and injection of water, corrosion factors, etc.
At present, garnet sand has gradually replaced traditional abrasives for sandblasting. The main advantages of garnet sand are: the hardness is as large as 7.5-8 on the Mohs, and it does not contain free metals and harmful heavy metals. It is very good, and the crushing rate is low and can be recycled. 5-15 times, this also greatly reduces the cost.
In the previous sandblasting and rust removal, quartz sand and river sand are commonly used. These materials are rich in free metals and harmful heavy metals, and they will be broken during rust removal, which reduces the efficiency of rust removal and increases costs. The garnet produced by the company has been cleaned and cleaned very well after six times, and there will be no dusty phenomenon during the operation.
