Sandblasting machine is using compressed air as the power, to form a high-speed jet beam of the spraying material (shot peening glass beads, steel shot, steel grit, quartz sand, emery, iron sand, sea sand) high-speed jet to be handles the workpiece surface, make the change on the surface of the workpiece surface appearance and mechanical properties, due to the abrasive impact to the surface and the cutting effect, make the surface of the workpiece by a certain cleanness and different roughness, make the workpiece can improve the mechanical properties of the surface, thus improves the fatigue resistance of the workpiece, when processed at the same time, the need to pay attention to the attention of container fittings products during forging. Increased between it and the coating adhesion, extend the durability of the coating, but also to the flow of paint and decoration, the impurity, on the surface of the noise and oxide layer removed, at the same time make medium surface coarsening, make the base material surface residual stress and improve the surface hardness of the base material.
Sandblasting machine USES
1. Surface cleaning
After the heat treatment of the scale, the salt, residual oil, etc. Black (any) oxide skin color casting, sand, etc; WuYuLiang scale machining of precision casting, sand, etc.; Mechanical product residue, micro burr, etc; Product scale, welding slag, etc.; Cold and hot rolled steel plate (steel) scale, rust, etc.; All kinds of mold cavity sediment release agent, organic glass, etc.; Sintered residue on the surface of the ceramic element; Plastic von berg systeme flash; Radioactive elements on the surface of the object; Gate bridge, hydropower station, ship, building; Airport runway rubber adhesive layer; The train carriage; Various pipes and containers; Old parts of oil, adhesives, etc.; Container fittings paint residue, rust layer and the attachments etc. Error on porcelain sintering layer; Scratches on the surface of the decoration...
2. The surface pretreatment before coating
Before painting, painting; Before coating; Metal spraying; Zinc, chromium, nickel before; Before the oxidation treatment. Before detection of feng shui.
3. Change the physical and mechanical properties of workpiece increase or reduce the surface roughness; Surface tensile stress to compressive stress; To improve the lubrication state of surface; The noise of the couple sport; Improve the surface friction coefficient.
4. The surface finishing processing
Outside the metal decorative surface polishing; Inferior smooth or diffuse surface; Surface of wood products
