The process of anti-corrosion treatment of A588 weathering steel plate

The anti-corrosion design of the A588 weather-resistant plate is also designed in many aspects. The anti-corrosion design has strict requirements on the quality and use of the weather-resistant board. What is the process of anti-corrosion treatment of weathering board?

Anti-corrosion treatment of weather-resistant plate is to add a resistant surface coating (or coating) to the weather-resistant panels that need to be protected. The materials used for this type of coating vary but commonly used are paints, plastics, rubber, ceramics and other metals applied to the surface by various means such as electroplating, hot-dip galvanizing, spraying, etc., such as aluminum , zinc, chromium or nickel, etc.

When using protective coating systems to protect metal structures from corrosion, everyone involved, from component designers to painters to paint inspectors, must have at least a basic understanding of corrosion and the factors that affect it. Such knowledge of chemistry is indispensable.

A588 Weathering steel plate is the high-quality supply material in the engineering of various large-scale steel plate landscapes. Weathering steel plate is a kind of alloy steel, which can form a relatively dense rust layer on the surface after several years of outdoor exposure, so it does not need to be painted for protection. The properties of a weathering steel plate depend on its thickness and alloy composition.

Due to its unique rough appearance, weathering steel plates are widely used in outdoor sculptures (such as "Picasso in Chicago") and building exterior decoration. It has also been used in bridges and other huge structures such as the Australian Center for Contemporary Art. In ocean transportation, weathering steel plates are used to make containers. The use of weathering steel plates still faces the following problems. ·

Corrosion of solder joints: The oxidation rate of solder joints must be the same as that of other materials, which requires special welding materials and techniques.

Corrosion by stagnant water:the weather-resistant steel plate is not stainless steel. If there is water in the recess of the weather-resistant steel plate, the corrosion rate will be faster, so drainage must be done well.

Salt-rich air environment: Weathering steel plates are sensitive to salt-rich air environments like Hawaii. In such an environment, the surface protective film may not prevent further internal oxidation.
