How to use pressure blasting machine for surface treatment
The pressure sand blasting machine is used for the impact and cutting effect of the abrasive on the surface of the workpiece, so that the appearance of the workpiece has a certain degree of cleanliness and different roughness, which improves the mechanical properties of the surface of the workpiece, thereby improving the fatigue resistance of the workpiece. It increases the adhesion between the coating and the coating, prolongs the durability of the coating film, and is also conducive to the smooth embellishment of the coating. It removes impurities, variegations and oxide layers on the surface, and roughens the surface of the medium together. The effect of substrate residual stress and the improvement of substrate hardness.
Oxidation scale, residual salt, residual oil, etc. after thermal treatment of the appearance of the workpiece by the pressure type sand blasting machine; oxide scale, molding sand, etc. of black (non-ferrous) castings; oxide scale, molding sand, etc. of fine castings with no margin to be processed; Residues, micro-burrs, etc. of machined parts; scales and slag of welded parts; scales and rusted layers of cold and hot rolled steel plates (profiles); release agents and deposits for various mold cavities, etc. ; Sintering residues on the surface of ceramic components; Flash of plastic molded parts
