Due to the fact the sand equipment functioning atmosphere and so on, which are triggered by the sand making machine rust is usually a normal reaction, when placed within the air for any long time will rust. For the reason that the sand making machine parts are commonly relatively harsh atmosphere, so far more conveniently trigger rust and influence the production high quality. So tips on how to retain the sand making machine and gear can accurately operation becomes extremely important.
A, chemical cleaning: may be the use of acid and metal oxide chemical reaction, a technique of removing rust and remove the sand making machine metal surface rust, generally known as pickling rust, can only operate within the workshop.
Two, the small wind-driven or electric rust: important in electric or compressed air as a driving force, the assembly suitable descaling device, reciprocating or rotary motion, so as to adapt towards the needs of a variety of occasions of rust. Because the angle grinder, wire brush, pneumatic needle rust remover, pneumatic chipping hammer, tooth kind rotary descaling device, which belongs for the semi mechanized equipment, tools, light, flexibility, can completely eliminate rust, coating, the coating for wool processing, but can not attain the surface processing good quality and the work efficiency is low injection processing. Could be employed in any position, in particular extensively utilised in the repairing course of action.
3, the high-pressure water abrasive cleaning by higher pressure water jet influence (plus the function of abrasive grinding) and prized part of water damage and corrosion coating on the steel adhesion. Its characteristic is no dust pollution, no damage to steel, the progress of rust removal efficiency greatly, as much as 15m2/h or much more, derusting top quality. But right after rust removal of steel to rust, to be wet with a special coating rust paint, possess a higher influence around the general function of paint coating.
Four, apply anti oxidation in iron products surface coating paint: mineral oil, paint or baking enamel, spray and so on.. Inside the iron and steel surface by electroplating, hot plating technique of coating a layer of rust of metal, which include zinc, tin, chromium, nickel and so on.. The metal oxide film surface can kind a layer of dense, so as to stop iron items and water, air and also other material make contact with and rust. Can also be utilised to chemically iron merchandise surface is a layer of dense oxide film and not chaos to prevent rusting iron items.
