The sandblasting machine uses compressed air as power. The compressed air carries sand (emery, corundum, etc.) against the surface of the workpiece, which changes the mechanical properties of the outer surface of the workpiece. There are many types of sand blasting machine, but the ultimate goal is to improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, and it is also conducive to the leveling and decoration of the coating. , It removes impurities, variegated colors and oxide layers on the surface, and at the same time roughens the surface of the medium, eliminates the residual stress of the workpiece and improves the surface hardness of the substrate.
The shot blasting machine uses an electric high-speed rotating impeller to throw small steel shots or small iron shots out to hit the surface of the part at a high speed, so the oxide layer on the surface of the part can be removed. At the same time, steel shot or iron shot hits the surface of the part at high speed, causing the lattice distortion on the surface of the part to increase the surface hardness. The shot blasting machine is a method of cleaning the surface of the part. The surface of the part is strengthened. Generally, shot blasting is used for regular shapes, etc., several blasting heads are up and down, left and right together, with high efficiency and low pollution.
Dry sand blasting machine rust removal method is low cost, but the dust generated during work is large, which pollutes the environment, and it also seriously endangers the health of the operators. In addition, dry sand blasting machine rust removal sometimes generates sparks during work. It cannot be used in flammable and explosive places.
The water sand blasting machine is a combination of water jet and sand blasting technologies. At the same time, it has the environmental protection and explosion-proof characteristics of water jet and the superior rust removal and paint removal effects of sand blasting. It is very suitable for flammable and explosive places, especially in Anti-corrosion operations are carried out under normal operating conditions for oil storage tanks.
The water sand blasting machine belongs to pure physical cleaning. It only needs to be connected to the power and water source when using it, without adding any chemical agents. It is a high-tech product promoted by a green country. In general, the editor recommends water blasting to remove rust. Although the price is not as low as dry blasting, water blasting is more environmentally friendly and safer.
