 Packaging: 25 kg loaded one, the chemical composition of the inert silica chemically active interference concerns 
 2, circular elastic particles, impact resistance, can be recycled many times, less wear and tear 
 3, the nozzle wear small, extend nozzle life 
 4, the ball surface, will not damage the machined surface and the precise size 
 5, after processing, the workpiece table machine is smooth, with a special beauty, improve product value 
 6, suitable for dry, wet sandblasting 
 7, the metal micro-cracks with a fine glass beads in the wet blasting is easy to show out, beads strike aircraft parts, to eliminate its application of force in order to increase the fatigue strength and to reduce friction and wear 
 Sand-blasting, paint, in addition to carbon deposition, in addition to machining marks 
 3, the nozzle wear small, extend nozzle life 
 4, the ball surface, will not damage the machined surface and the precise size 
 5 after treatment, the surface smooth, with a special beauty, and increase product value 
 6, the rubber mold in addition to dirt 
 7, road marking reflector with 
 8, art exterior decoration
