Many users are inexperienced when buying dust-free emery sand and cannot distinguish the quality, which directly affects the abrasive quality, wear-resistance, and service life. Therefore, users should understand some specific skills and do not choose blindly.
The main component of emery is alumina, and the hardness of dust-less emery sand is distinguished according to the level of aluminum content. Also, from the appearance point of view, the color is the best brown. Besides, you can try whether it is fragile to judge the quality when choosing. The specific gravity of sandblasted emery needs to be considered when selecting, and the appropriate particle size should be selected according to the caliber of the spray gun. If the customer’s requirements are not high, you can choose according to the emery’s reusable times.
We can choose according to these principles:
- According to the grade: According to the different aluminum content, it is divided into first-grade dust-free sand, second-grade dust-free sand, and third-grade dust-free sand. Many customers do not know the level of granularity and can follow the manufacturer’s recommendations.
- According to the application: Glass sandblasting is currently the most used dust-free emery. Each customer has different requirements, so when choosing dust-free sand, the customer should consult the relevant technical personnel in advance and can refer to the manufacturer’s opinions at the same time.
