About glass bead blasting media
Glass beads have been suggested for air abrasion as a softer material than sharp, hard alumina. The same paper notes that alumina air abrasion leaves surface defects such as flaws, embedded alumina and microcracks.
Airborne-particle abrasion alters the surface of a material with abrasive particles propelled by compressed air or other gases. OSHA defines abrasive blasting as the forcible application of an abrasive to a surface by pneumatic pressure, hydraulic pressure or centrifugal force.
How aluminum oxide and glass beads differ
- Aluminum Oxide — Sharp and hard.
- Glass Beads — Softer than alumina.
What to look at when choosing blasting media
Particle: aluminum oxide for blasting castings is frequently 50 micrometres.
Dust: OSHA defines respirable dust as airborne dust in sizes capable of passing through the upper respiratory system to reach the lower lung passages.
