sandblasting materials micro glass beads
sandblasting materials micro glass beads/The glass micro ball production line uses the principle of flame flotation to break the recycled waste glass into certain granularity particles and send the glass particles into the flame in a certain way. Under the action of the flame, Glass particles are softened, melted, beaded, cooled and solidified to become glass beads.
Characteristics
1. Clean, transparent appearance, no obvious bubbles and impurities
2. Chemical composition is stable
3. Resistance to impact, can be recycled many times, less loss
4. No injury and machining surface and precision dimensions
