Blasting sand is a powerful abrasive material used in sandblasting to remove surface contaminants and prepare surfaces for coating or bonding. Its versatility and cost-effectiveness make it a popular choice for industries such as automotive, construction, and manufacturing.
Sandblasting is a surface treatment technology that removes or etches the surface layer by spraying high-speed abrasive particles to achieve the effects of cleaning, polishing, improving surface roughness, and increasing surface adhesion. Sandblasting is commonly used in the surface treatment of various materials, including metals, glass, plastics, etc. Sandblasting can be performed using manual, automatic or mechanized equipment. By the way, sandblasting is often used in conjunction with anodizing.
Advantages of sandblasting
1. Removes surface dirt and oxide layers, and has a good cleaning effect.
2. Greatly improves surface adhesion, which helps the adhesion of coatings and other surface treatments.
3. Can improve surface quality and roughness, and can achieve a certain degree of finish.
4. Used on some metal materials, it can increase the tensile strength of metal materials.

Disadvantages of sandblasting
1. The sandblasting process will generate noise and dust, which may cause certain pollution to the environment.
2. Sandblasting will wear the surface layer of the material. If it is very hard or special material, sandblasting may cause damage to it.
3. The equipment and materials required for sandblasting are more expensive than general surface treatment methods.
4. The sandblasting process requires a period of maintenance and upkeep, and materials such as nozzles and abrasives need to be replaced.
