Introduction
1. Sandblasting (shot) glass microbeads not only have certain mechanical strength and hardness, but also have enough elasticity, which can be used repeatedly for several times, with the same effect and not easy to be broken;
2. Sandblasting (shot) glass microbeads with uniform particle size; after spraying, the brightness coefficients of sandblasting devices are kept uniform, which is not easy to leave watermark;
3. Sandblasted (shot) glass microbeads are made of non-alkaline sodium-calcium material, with good chemical stability and will not contaminate the processed metal;
4, sand blasting (shot) glass beads smooth surface, with good finish, does not damage the mechanical precision of the workpiece
5, sandblasting (shot) glass beads appearance spherical particles, only a few impurities. Its testing method is strict, high quality, and can meet the requirements of international and domestic standards.
6. Sandblasted (shot) glass microbeads have a hardness of no less than 6 Mohs and a certain toughness, and the roundness rate is not less than 90%

Product Features
1. The chemical composition is inert silica, and there is no concern about chemical activity interference;
2. Round elastic particles, impact resistant, can be cycled many times, and less loss;
3. Less wear on the nozzle and prolong the service life of the nozzle;
4. The surface of the sphere will not damage the machined surface and precise dimensions;
5. After processing, the surface of the workpiece is smooth and has a special aesthetic feeling, which improves the value of the product; it damages the processing surface and precision dimensions;
6. Suitable for dry and wet sandblasting operations;
7. Metal micro cracks are easily displayed after wet sandblasting with fine glass beads;
Application areas:
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
