Selection of sandblasting abrasive

Before the rapid development of the sandblasting abrasive industry, the commonly used sandblasting materials in industrial production include river sand, quartz sand, cold iron sand, brown corundum, and so on. However, with the continuous advancement of technology, the sandblasting abrasive industry has become more and more mature and has achieved great development. Many new types of sandblasting abrasives have been bred, and among these new abrasives, garnet sand has come to the fore. As the sandblasting abrasive favored by more and more companies, how does garnet sand gain a foothold in the field of sandblasting abrasives?
The texture of garnet sand is hard, and the model hardness can reach 7.5-8, which is higher than common sandblasting abrasives such as quartz sand, sea sand and river sand. In addition, garnet sand is a kind of crystal with multiple edges and corners. It is easy to form angular particles. It can not only remove rust, oxidized paint, and metal plating surface contaminants, but also can form an ideal rough surface on the cleaned metal surface, improve the adhesion between the anti-corrosion layer and the protective layer, and also improve the sandblasted object Service life.
Another important reason for choosing garnet sand for sand blasting is that garnet sand is a kind of sand blasting abrasive without free silicon. That is to say, garnet sand is not easy to produce dust during sand blasting operation, which is harmful to the surrounding environment. There is no pollution and no harm to the health of the staff. It is a green and environmentally friendly sandblasting abrasive.
