What are the blasting machine processes?
Pre-treatment stage of sand blasting process The pre-treatment stage of sand blasting machine refers to the treatment of the surface of the workpiece before the workpiece is sprayed and sprayed with a protective layer.
The quality of the sand blasting machine's pre-treatment process affects the adhesion, appearance, and humidity and corrosion resistance of the coating. The pretreatment is not done well, and the rust will continue to spread under the coating, causing the coating to peel off. After carefully cleaning the surface and the general simple cleaning of the workpiece, the coating can be compared with the exposure method, the life span can be 4-5 times. There are many methods for surface cleaning, but the most commonly accepted methods are: solvent cleaning, pickling, hand tools, power tools.
Sandblasting machine process stage
The sand blasting machine process uses compressed air as the power to form a high-speed spray beam, and sprays the blasting material onto the surface of the workpiece to be processed at high speed, which changes the appearance of the external surface of the workpiece. Due to the impact of the abrasive on the workpiece surface and the cutting action, Obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved.
One sandblasting principle
Sand blasting uses compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore, quartz sand, corundum, iron sand, Hainan sand) on the surface of the workpiece to be processed at high speed, so that the outer surface of the workpiece surface or The shape changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved. Therefore, the fatigue resistance of the workpiece is increased, and the workpiece is increased. The adhesion between it and the coating prolongs the durability of the coating film, which is also conducive to the leveling and decoration of the coating.
