After using a piece of sand making machine, the user will call to ask how the rust inside the machine is removed! Due to the working environment and nature of the sand making machine equipment, if the maintenance is not taken care of, it is easy to appear rust on the surface of the sand making machine equipment, which not only affects the aesthetics of the sand making machine equipment, but also slowly erodes the sand making machine equipment. , which in turn affects the performance of the machine. So if there is rust on the sand making machine to remove it as soon as possible, then how come rust removal, today SBM machinery will come to share with you.
For rust removal of sand making equipment, rust can be removed with compressed air. Compress the air and install a suitable descaling device to reciprocate or rotate to meet the rust removal requirements. If the parts of the sand making machine are rusted, the wire brush should be used to remove the rust. The roughness of the surface of the scale cannot be removed, and high-quality, high-efficiency surface treatment can be achieved.
1. Chemical descaling: The chemical reaction between the acid and the metal oxide is used to remove the rust products on the metal surface of the sand making machine, which is commonly referred to as pickling and rust removal. This method is only suitable for operation in the workshop.
2. High-pressure water abrasive rust removal: The impact of high-pressure water jet and the action of water raft destroy the corrosion and the adhesion of the coating to the steel plate. The method has no dust pollution, does not damage the steel plate, greatly improves the rust removal efficiency, and has good rust removal quality. However, the steel plate after rust removal is easy to return to rust, and it is necessary to apply a special wet rust-removing paint, which has a great influence on the coating of general performance paint.
3, small air or electric derusting: mainly powered by electric or compressed air, equipped with appropriate descaling device, reciprocating or rotating motion to meet the rust removal requirements of various occasions;
4. Apply anti-oxidation paint: Apply mineral oil, paint or fired enamel, spray, etc. on the surface of iron products. A layer of metal that is not easily rusted, such as zinc, tin, chromium, nickel, etc., is plated on the surface of the steel by electroplating or hot plating. These metal surfaces can form a dense oxide film to prevent iron products from rusting by contact with substances such as water and air. Chemical methods can also be used to form a dense and stable oxide film on the surface of the iron article to prevent rusting of the iron product.
