Large coils of galvanized wire will rust after long-term use, so how should galvanized iron wire be derusted? Galvanized iron wire manufacturers will tell you.
Physical methods mainly include manual derusting and mechanical derusting. Chemical derusting generally adopts the method of pickling. In practical applications, different derusting methods are usually selected according to the surface corrosion of the workpiece and different post-treatment processes. Among them, pickling and derusting are more commonly used. The steel workpiece with scale or rust is etched in pickling solution, mainly to remove the oxide or rust layer on the surface of the steel.
Generally, the main causes of iron wire rusting are: when there is some dust on the steel mesh in the wire mesh, it can be cleaned with some water or alkaline solution at this time. The second is floating iron or pre-embedded iron, iron will rust, and the iron connected to the stainless steel expanded mesh will rust, so these irons must be treated, and carbon steel wire brushes can be used to process carbon steel, etc. Then there are scratches. For the appearance of scratches, it is mainly during the production process that some stubborn iron scratches are needed for stainless steel expanded mesh special polishing cleaning machines.
Galvanized iron wire is very common in practical applications. Some people think that galvanized iron wire will not rust, but it is not. Metal corrosion is caused by the chemical or electrochemical action of the surrounding medium. According to different media, it can be divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion, etc. Atmospheric corrosion is relatively common, because metal products are in contact with the atmosphere during processing, transportation and storage, and there are always conditions of atmospheric corrosion.
