Since the sand equipment operating natural environment and the like, which can be triggered with the sand making machine rust is a normal reaction, when put inside the air for many years will rust. As the sand making machine components are commonly reasonably severe ecosystem, so extra very easily result in rust and impact the production good quality. So ways to manage the sand making machine and products can precisely procedure becomes incredibly crucial. A, chemical cleaning: may be the utilization of acid and metal oxide chemical response, a technique of getting rid of rust and get rid in the sand making equipment metallic area corrosion solutions, recognized as pickling rust, can only run in the workshop. Two, the small wind-driven or electric rust: major in electric or compressed air for a driving drive, the assembly suitable descaling product, reciprocating or rotary motion, in an effort to adapt to the needs of varied occasions of rust. As being the angle grinder, wire brush, pneumatic needle rust remover, pneumatic chipping hammer, tooth variety rotary descaling unit, which belongs to the semi mechanized equipment, equipment, and large overall flexibility, can extensively remove rust, coating, the coating for wool processing, but can not get to the floor processing quality, operate efficiency is minimal injection processing. Can be utilized in any situation, specifically extensively utilized in the restoring system. 3, the high-pressure water abrasive cleansing by high force drinking water jet influence (moreover the role of abrasive grinding) and prized purpose of drinking water injury and corrosion coating about the steel adhesion. Its characteristic is not any dust pollution, no hurt to metal, the progress of rust removal efficiency greatly, up to 15m2/h or even more, derusting high quality. But immediately after rust removal of metal to rust, to get moist which has a specific coating rust paint, have a increased impact on the overall purpose of paint coating. 4, implement anti oxidation in iron products and solutions floor coating paint: mineral oil, paint or baking enamel, spray and many others.. Within the iron and steel floor by electroplating, warm plating technique of coating a layer of rust of metal, such as zinc, chromium, nickel, tin. The metal oxide movie floor can sort a layer of dense, in order to stop iron goods and drinking water, air together with other content get hold of and rust. May also be used to chemically iron merchandise surface area is actually a layer of dense oxide movie and never chaos to avoid rusting iron products and solutions.
