Corrosion of metal brings big problems in the manufacture and operation of metal. Specialists are always looking for ways to protect the materials from this scourge. The fact that the metal active contact with the environment, engaging in a variety of electrochemical or chemical reactions. The result of such processes is the oxidation and destruction of material. Experts demonstrate disappointing facts.
By The research carried out corrosion causing huge damage to industry, which amounts to 4% of gross national product of each state. Loss of metal as high as 20% per year. Corrosion – a natural process. It can not be avoided, but can only slow it. In the atmosphere, there are plenty of substances such as oxygen and water.
Acting on the metal, they cause its oxidation. The entry of the material in reaction is its oxidation. On the metal is often possible to observe rust. That she is a demonstration of the chemical processes occurring. This means that corrodes steel structure that is destroyed. For Surface protection designs use special coatings. One of the most economical, efficient and reliable way to conduct anti-corrosive treatment of the product is galvanizing. This procedure applies to protect a wide variety of metal products. First of all, zinc are: mast antennas, telegraph wires, wire ropes, sheet metal, plumbing, fasteners machinery and instruments, pipelines. An equally important step is the pre-processing of products. Galvanising is produced in factory conditions, a way of galvanizing or thermal diffusion method. Design finds special thin coating, resistant to corrosion. Zinc layer significantly prolongs life and improves the reliability of the product and its parts. In practice, it is proved that the metal is not protected from corrosion, are ten times less than secure. Demand for galvanizing continues to grow.
