How to choose sandblasting abrasive brown fused alumina white fused alumina glass beads

Sandblasting is powered by compressed air to form a high-speed jet beam to spray the sprayed materials (emery, garnet, quartz sand, glass beads, etc.) on the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the workpiece surface is changed. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, the fatigue resistance of the workpiece is improved, and the difference between it and the coating Between the adhesion.

Sandblasting abrasives have the advantages of high hardness, high specific gravity, stable chemical properties and unique self-sharpening properties. It is an ideal material for sandblasting, rust removal, surface pretreatment, grinding and polishing.

The main sandblasting abrasive we can supply is

Ceramic beads
Glass beads
Brown fused alumina
White fused alumina
