If the river stone sand making machine rusts, it will affect the sand making process, and then the equipment needs to be maintained for a long time; for example, the rust removal of the sand making machine is one of the daily maintenance, and the rust removal saves time and labor; here we will mainly explain the maintenance tips of a sand making machine:
Method 1: Small-scale pneumatic or electric rust removal, mainly powered by electricity or compressed air, assemble a suitable rust removal device, and perform reciprocating or rotating motion to meet the rust removal requirements of various scenes.
Method 2: Use high-pressure water abrasive grains to remove rust from the river stone sand making machine: Use the impact of high-pressure water flow (plus abrasive grain grinding) and water skid action to destroy the rust and the adhesion of the coating to the steel plate. There is no dust pollution at the plugging point, no damage to the steel plate, greatly improving the rust removal efficiency, which can reach more than 15mZ/h, and the rust removal quality is good. However, the steel plate after rust removal is easy to rust, and paint is needed as a special wet rust removal coating, which has a great impact on the paint work of the performance coating.
Method 3: Use anti-oxidant paint to remove rust from river stone sand making machine: Apply mineral oil, paint, burn enamel, and spray forming on the surface of iron element products. The surface of iron element steel is plated with metals that are not easy to rust, such as submetallic lead, tin, chromium, nickel, etc. A dense oxide film is formed on the surface of these metals, which can prevent iron products from rusting due to contact with water, air, etc.
Method 4: Chemical rust removal: The soil uses acid and metal oxides to chemically react to remove the rust products on the metal surface of the sand making machine. It is the usual method of removing rust by pickling.
