1) Product Introduction
Glass beads for sandblasting has the features of chemical stability, high mechanical intensity and hardness. They can beÃ? blasted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity.Â
2) Product Specification
Main products specification for sandblasting according to following table:
No. Diameter(um) Corresponding sieve size
1 850-425 20-40
2 425-250 40-60

High Strength Glass Beads (for Blasting)
With compressed air as implicit power, this product is made by sprinkling beads under high speed and pressure on the surface of workpiece for peening and polishing.
Other purposes of the products are as follows:
1.� Clear diverse moulds of impact forging, forging, glass, rubber and plastic, metal casting and extrusion.
2.� Eliminate tensile stress, increase fatigue life and enhance stress corrosion resistance. For example, aircraft engine turbo, vane, shaft, undercarriage, diversified springs and gears, etc.
3.� Clean and remove slitter edge and burr on the circuit plate and plastic-sealed geminate transistors before stannum soldering
4.� Remove stems in the piston and cylinder and provide bright and half-lackluster surface for medical mechanical instruments and automobile parts
5. Clear electromotor and such parts as loop, electric brush and rotor of during heavy repair
6.� Clean up and remove burr of metal tube and precisely-melten non-ferrous metal tube. Be used for peening aggrandizement and polishing of textile machinery parts.

The raw materials are made of bao, tio2, rare earth, etc. They have the characters of melting roundness nearly 100%, refractive index 1.9-2.4, small volume, prone to adhere to surface of road marking and clothing. The patented coating materials and coating processing make our products be more transparent and increase refractive index. Its refractive effect is 6 times better than the common glass beads. A perfect circle, coupled with the high refractive index of light refraction brought about an excellent reflector. It is core material for producing reflective fabric, reflective foil, highlight class film, reflective clothing, reflective ink, reflective paint, and other new composite material. It can be widely used in roads, ports, mines, firefighting, traffic safety and other fields, and playing a highly symbolic role.

1. The chemical composition is inert silicon dioxide and there is no worry about the interference of chemical activity;
2, round elastic particles, impact resistance, can be recycled many times, less loss;
3, the spray wear is small, extend the service life of the nozzle;
4, the surface of the ball, will not damage the processing surface and precision size;
5. After treatment, the work-piece surface is smooth, with a special aesthetic feeling, improving the product value;
6. Suitable for dry and wet sand blasting;
7. The fine glass beads used for the metal micro-cracks can be easily displayed after the wet sandblasting;
8, for the processed work-piece with matte effect, highlighting the metal color, not rust and other advantages, no need to carry out pickling derusting treatment.

Glass Beads are manufactured from lead-free, soda lime-type glass, containing no free silica that is made into preformed ball shapes. Glass beads produce a much smoother and brighter finish than angular abrasives. Glass beads can be recycled approximately 30 times. Chemically inert and environmentally friendly, glass beads are an acceptable method of metal cleaning or surface finishing when properly controlled.
Glass Bead Blasting
Glass bead blasting produces a clean, bright, satin finish, without dimensional change of the parts. Available in a wide range of sizes, glass beads are primarily used in blasting cabinets for honing, polishing, peening, blending, finishing, removing light burrs and cleaning most light foreign matter. For delicate thin-walled parts and thin welds, peening with glass bead abrasive material provides the right balance of stress relief without over-stressing and causing damage. Consider the size of perforations or holes through which the glass beads must pass when screen separating parts from media after use.
