What are the effects of garnet sand as a sandblasting material?
1. Efficient rust removal ability
Garnet sand has the characteristics of high hardness and high density. Its Mohs hardness can reach 7.5-8, which is higher than other commonly used sand materials. It can effectively remove rust, scale and pollutants on the metal surface. At the same time, its particle size is uniform, ranging from 6-325 mesh, ensuring the uniformity and thoroughness of rust removal. This makes garnet sand a high-quality choice in the field of sandblasting and rust removal.
2. Good surface roughness
The crystal structure of garnet sand is tight, mostly equiaxed crystals or cell ring crystals. It can maintain a good shape and particle size during the sandblasting and rust removal process, and will not be easily broken or worn. This characteristic makes the treated metal surface not only clean, but also presents an ideal angular rough surface, which increases the surface area of the metal and improves the adhesion of the interface. This is crucial for subsequent coating, spraying and other processes.
3. High reusability
Garnet sand has good reusability. After recycling and regeneration, it can be recycled many times without causing any pollution to the environment. This not only reduces the processing cost, but also helps to achieve sustainable use of resources.
4. Environmental protection and safety
Compared with traditional sandblasting materials, garnet sand does not contain free silicon and other harmful substances, and is harmless to the human body and the environment. This meets the requirements of green development of modern industry, and is also one of the important reasons why garnet sand is widely used in the field of sandblasting and rust removal.
5. Wide range of applications
Garnet sand is not only suitable for sandblasting and rust removal of metal surfaces, but also can be used for surface treatment of materials such as glass, stone, and ceramics. Its excellent performance and wide range of applications make garnet sand one of the indispensable abrasives in the industrial field.
