What are the advantages of shot blasting technology
At present, enterprises usually use cleaning equipment to remove the surface oxides and adhesives on the surface of castings or parts, and the cleaning equipment will improve their surface quality. What is shot blasting technology? Cleaning equipment can be divided into wet cleaning equipment and dry cleaning equipment according to the working environment. According to whether there is abrasive in cleaning, it can be divided into non abrasive cleaning and abrasive cleaning: non abrasive cleaning is to complete the surface cleaning of workpieces by using mutual scraping and friction between workpieces. This method is mainly used in cleaning small castings without fear of collision; Abrasive cleaning is to use high-speed flying projectiles to polish the surface of the workpiece. It can not only remove oxides and adhesives on the surface of the workpiece, but also make the surface of the workpiece reach a certain surface quality. Moreover, this method requires less investment and produces less pollution, making it applicable to workpieces of various materials, weights and sizes. Therefore, abrasive cleaning is the main method used by enterprises to clean parts at present.
Abrasive cleaning can be divided into shot blasting machine cleaning and shot blasting machine cleaning according to the way in which the shot is accelerated: shot blasting uses high pressure to compress air as power to speed up small steel shot and then throw it on the surface of parts to achieve the purpose of cleaning; Shot blasting is to use high-speed rotating blades to accelerate the shot to a certain speed and throw it to the surface of the parts to be cleaned to remove the sand, oxide skin and burrs on the surface of the workpiece. Shot blasting technology is mainly used to remove the oxide film and black skin on the surface of the workpiece due to casting, forging and heat treatment. This method can not only make the workpiece beautiful and improve the welding tensile stress, but also improve the fatigue strength and corrosion resistance of the part surface to achieve the purpose of improving the service life of the workpiece, At the same time, this method can also improve the roughness of the workpiece surface to increase the adhesion of the paint film for subsequent painting to the workpiece. Therefore, this technology is widely used in such fields as automobile, military industry, construction, locomotive, ship, etc.
Compared with other cleaning technologies, shot blasting cleaning technology has many advantages:
