Purpose of pressure blasting machine
1. The surface of the workpiece is cleaned after heat treatment, scale, residual salt, oil, etc .; oxide scale, molding sand, etc. of black (non-ferrous) castings; oxide scale, molding sand, etc. of precision castings are not spared; residues of machined parts Scales, burrs, etc .; scales and slags of welded parts; scales and rusted layers of cold and hot rolled steel plates (profiles); mold release agents for various mold cavities, plexiglass deposits, etc .; ceramic components Sintered residues on the surface; flash of plastic molded parts; radioactive elements on the surface of the object; bridges, hydropower stations, ships, buildings; rubber coatings for airport runways; train cars; various pipes and containers; old parts Oil stains, attachments, etc .; residual paint, rust, and attachments on containers; wrong sintered layers on porcelain; scratches on decorative surfaces
Pressure blasting machine has the following applications:
Pre-treatment of workpiece coating and workpiece bonding
The sand blasting of the pressure type sand blasting machine can remove all the dirt and other dirt on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called matte surface).
The abrasive size can reach different levels of roughness, which greatly improves the binding force between the workpiece and the coating and plating material. Or make the adhesive bond more firm and better quality.
