Garnet sand and copper slag are widely used and popular sandblasting abrasives. Do you know the difference between them for sandblasting?
1.Garnet sand sandblasting has a high safety factor
Garnet sand is a non-metallic ore, does not contain free silicon, no heavy metals. In the process of sandblasting, there will be no dust ejection,, environment friendly and safe; Copper slag is a non-ferrous heavy metal. Sand blasting with copper slag has potential harm of heavy metal inhalation in the body.
2.Garnet sand has high hardness
When blasting objects with high hardness such as stainless steel, garnet sand is more practical. The hardness of garnet sand is between 7.0-8.0, and the hardness of copper slag is much lower. Garnet sand is polyhedral, with more sharp corners, so as to have higher efficiency in sandblasting, After the garnet sandblasting, the surface of the workpiece has no obvious peaks and trouges, the roughness of 30-75 microns, can achieve the highest grade Sa3 sandblasting standard, copper slag can not achieve such an effect.
3.Garnet sandblasting extends the life of the coating
The chloride content of garnet sand is very low, and soluble salt will not be produced after sandblasting, which can achieve the adhesion of the coating for many years. Copper slag has more components, and the chloride content is higher than that of garnet sand. Therefore, the use of garnet sand blasting can extend the life of the coating
4. low cost of copper slag sandblasting
As a low-cost consumable medium, suitable for open-air impact blasting cleaning, fast and effective surface cleaning When the need for fast and effective sandblasting treatment, copper slag is the ideal choice, copper slag is especially suitable for ships, Bridges sandblasting, the use of low cost, while up to SA2.5
According to different sandblasting uses and project plans, it is important to choose the appropriate sandblasting abrasives, saving the cost and getting more economic benefits.
