The shot blasting rust-removing machine utilizes compressed air as its power source, forming a high-speed jet stream to blast the material at high velocity onto the surface of the workpiece to be treated. Due to the impact and cutting action of the abrasive on the workpiece surface, it removes debris, providing the workpiece with a certain degree of cleanliness and varying roughness, enhancing adhesion between the coating and the surface, extending the durability of the coating film, and facilitating the leveling and decoration of the paint.

Additionally, altering the surface appearance or shape of the workpiece enhances its mechanical properties, thereby increasing the fatigue resistance of the workpiece.

The abrasive materials used in the shot blasting rust removal machines include the following:

Quartz Sand: Sharp quartz sand is a cost-effective and useful abrasive, considered an economical abrasive for industrial construction, and is widely used in many places.

2. Copper Ore Sand: Also known as copper slag, it is a commonly used abrasive in open-air sandblasting, with a lower price point. It does not contain free silicon and does not pose health hazards to humans.

3. Corundum: Corundum has a largely inert effect on conventional corrosion, making it suitable for use on the surfaces of sandblasted stainless steel or colored metal materials without causing rust contamination.
