Characteristics of 20-40 mesh garnet sand for sandblasting
20-40 mesh garnet sand for sandblasting has the following characteristics:
Particle characteristics
The particle size range is about 0.5-0.8mm, which is a medium-coarse particle size. It has both high cleaning efficiency and a certain degree of fineness. It is suitable for metal surface rust removal, oxide layer removal and roughness increase operations.
The shape of the particles is a cube with edges and corners. After breaking, it can still maintain sharp edges and continue to provide efficient grinding capabilities.
Physical properties
High hardness, Mohs hardness of 7.5-7.9, can effectively remove stubborn dirt and rust, while avoiding excessive damage to the substrate surface.
The density is about 4g/cm³, the impact force is strong, the number of sand particles sprayed per unit time is large, and the processing efficiency is improved.
Application advantages
It is suitable for metal processing (such as welding, pre-painting treatment), shipbuilding, stone polishing and other fields, which can significantly improve the surface finish and coating adhesion.
It can be recycled more than 20 times, and its durability is better than ordinary sand materials (such as quartz sand and river sand), reducing the frequency and cost of material replacement.
Environmental protection and safety
The production process is clean and dust-free after washing and screening, reducing the pollution of the working environment.
The natural mineral components are non-toxic and harmless, meeting the requirements of environmental protection.
In summary, 20-40 mesh garnet sand has become an ideal choice for both efficiency and quality in industrial sandblasting due to its balanced particle size, high hardness and environmental protection characteristics.
