In glass bead blasting, the beads are made from a lead-free, soda-lime type of glass that will not harm the environment or ground water. Much of the bead material that is used in a blasting process can also be recovered by vacuum systems, and the beads are durable enough that they can be recycled into the blasting process up to 30 times. The glass beads are a transparent, solid soda lime glass, free of pits and excess air bubbles. The glass beads are chemically inert and do not effect the chemical characteristics of the mud system. The finish produced by using glass bead blasting is known as a satin look, which is a medium-level cross between a dull finish and a high-gloss finish.
Glass bead Blasting:
Bead blasting is a form of high pressure cleaning of a surface that is less damaging to the surface than typical abrasive blasting system. One of the most common materials used in bead blasting are small spherical particles of glass that are shot with air pressure at a surface to remove coatings, or to polish it. The ball-shaped glass beads produce the smoothest finish to a surface. Glass Beads has widen its applications including polishing, peening, blending, finishing, sanitizing, coating removal and de-scaling.
Glass Beads are also commonly used to clean very thin metal connections or welds where eroding the surface material could otherwise damage structural integrity or the viability of an electrical circuit. A bead-blasted surface also tends to be hardened through compaction, especially in the case of metals & surface cleaning which gives it increased fatigue resistance and better resistance to future scratches or other deformations.
