1, the chemical composition of inert silica, non-chemical activity interference concerns; 
 2, circular elastic particles, impact resistance, can be recycled many times, less wear and tear; 
 3, the spray loss, nozzle to extend the service life; 
 4 ball surface, will not damage the precision machined surface and size; 
 5, processing, surface smooth, with a special beauty, improve product value; 
 6, suitable for dry, wet sand blasting operations; 
 7, metal micro-cracks with a fine glass beads in the wet sand is easily displayed; 
 8, for the workpiece after processing with a matte effect, highlighting the qualities of metal, no rust, etc., without the need for acid rust treatment. 
 Uses: 
 1, the beads hit aviation parts, to eliminate the stress, to increase the fatigue strength, and to reduce friction and wear; 
 2, sand-blasting, paint, in addition to carbon, in addition to machining of the marks; 
 3, anodizing and plating before the treatment, in addition to clean the outside can help increase adhesion; 
 4, stainless steel parts of the weld surface cleaning and removal of scratches and other beauty of the process; 
 5, line cutting mold cleaning rust; 
 6, rubber mold of the dross; 
 7, with a reflective road marking; 
 8, the works of art equipment ordered by appearance.
