Oxidation Treatment Of Weather-resistant Steel Plates

The main technical support for weathering steel plates used as exterior wall materials is that weathering steel is superior to ordinary steel in terms of corrosion resistance. In natural weather, weather-resistant steel is formed by adding weathering elements such as chromium, bismuth, molybdenum, phosphorus, titanium, etc., so that the steel material forms a layer about 50-100 microns thick and adheres to the base metal. Rust layer and good oxide layer on the base material.

Due to the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from penetrating into the steel matrix, which slows down the rust of the steel, thus greatly improving the resistance of the steel to atmospheric corrosion. Research shows that depending on the composition of weathering steel, steel components are used in different environments, and the weathering resistance of weathering steel can be 5-8 times higher than that of ordinary steel.

This special dense oxide layer formed on the surface of weathering steel has a random and even natural rusty red color, making it an attractive building exterior wall material and a revolutionary material for the new generation of curtain wall decoration. Excellent value for money, stainless steel.

Why weather-resistant boards need to be oxidized:

First, quickly form a stable, uniform color, rust-red oxide film, not simply erased. In an environment with an outdoor temperature of 25 degrees Celsius, the rust treatment process is usually completed within 3 hours.

Second, under the catalytic scheme of rust treatment, the rough appearance is quickly roughened, making the structure volume and quality higher, improving visual and sensory effects, flexibly improving garden planning effects, and improving economic and artistic benefits! This is the feeling that planners are obsessed with . Generally speaking, weathering steel naturally rusts in 1-2 years. It only has 1-2 months of fine yellow rust, no feeling, simple rust!

Third, regardless of the local geographical location, local climate, location (facing southeast or northwest), the composition of the rust-red oxide film is uniform and stable!

Fourth, the treatment process is non-corrosive and will not affect the continued composition of the rust layer on the outer surface. It is environmentally friendly, non-toxic and harmless, and does not affect the growth of plants. It does not affect the "symbiosis" between the limited data and the surrounding plants, and the expression of the planning concept can continue
