1. This Glass Bead is made of high-grade soda lime glass containing about 70% SiO 2 . We have a variety of grades of glass beads, including blasting grades, grinding grades and road marking grades. It is a unique abrasive for a wide range of processes used in cleaning or metal surface strengthening processes, primarily for sandblasting equipment. In the manufacture of this product, the cullet is fused into a ball and annealed to eliminate internal stress and prevent breakage. This transparent, clear spherical structure product does not have particles embedded in the workpiece during use, contaminating the workpiece or causing other damage. Using different sizes of abrasives and different operating parameters, it achieves different gloss levels on the surface of the workpiece.
2. Glass Bead's excellent performance makes it not suitable for the workpiece surface when it is cleaned or deburred. Moreover, its inherent strength makes it suitable for use in equipment that can circulate abrasives. It is also widely used to treat workpiece surfaces with residual tension or under cyclic pressure to produce compressive stress layers for surface strengthening purposes. Glass Bead can also be used to reduce potential hazards such as surface erosion or surface fatigue.
