Rust is a kind of chemical reaction, when the iron after a long time will rust.Metal and the like, especially the metal iron rust easily, besides because of its chemical property active, at the same time also has a lot to do with external conditions.Water is one of the material of iron is easy to rust.Only water will not rust iron, however, only when the dissolved oxygen in the air in the water, oxygen and iron in a water environment, will generate iron oxide, which is rust.Rust is a kind of brownish red material, it is not as hard as iron, it is easy to fall off, after a piece of iron rust is complete, the volume can swell 8 times.If you don’t remove the rust, the spongy rust particularly easy to absorb moisture, the iron will rust faster.
Our daily use of crusher equipment, such as cone crusher, jaw crusher, sand making machine, or grinding mill, etc., almost all of the parts are made of metallic iron forging, if in the process of use or hold not to the maintenance or protection, so this kind of crushing machine is very easy to rust, which would lower production efficiency, and even lead to products do not meet our requirement.So we need to acquire a certain amount of rust removing knowledge.
On the surface of iron products protective cover, can prevent iron rust.Such as surface of iron products with mineral oil, paint, etc.;If discover the crusher of the phenomenon of metal surface with paint drop, need the paint brush on anti-oxidation in time;Iron products can use chemically generated on the surface of a compact and stable layer of oxide film, prevent iron rust.Acid can react with metal oxide at the same time, through this method to remove oxide on the surface of the machinery;Still can use high pressure water to rinse the impact on the surface of the metal corrosion, the advantage is not damage to the crusher equipment, and will not cause dust pollution, will improve the efficiency of rust removal.After removing rust, must be to deal with the iron surface, coated with lead paint, paint again, or other is not easy to rust on the metal plating.
