Glass beads(Microsphere) For Surface Treatment
Glass beads(Microsphere) are widely used in the impact treatment of surfaces. Their shape and chemical composition provide a variety of properties that no other media can claim.
When surfaces are impacted with Glass beads(Microsphere), the process is clean, safe and user-friendly. Glass beads(Microsphere) are used in all types of compressed air blast equipment, using a dry or wet process. Glass bead treatment may be the only surface treatment or it may supplement a treatment. For example, initial treatment utilizing aluminum oxide followed by Glass beads(Microsphere) to greatly improve the surface finish.
