Rust treatment process:
Rust treatment method is on the surface of weather-resistant steel, using chemical methods (rust liquid) to produce rust film, which is a kind of inhibition of the outflow of steel in the early stage of use Rust, make it. Manual treatment is generally 30 days. Usually, if the local damage of the general coating treatment is caused, the coating stripping phenomenon is caused, which rusts, in order to maintain the beauty Had to be repainted. However, the rust treatment method is to slowly dissolve the skin film, so that the resulting rust gradually expands to all, and a layer of skin film is covered on the surface of the steel Must be maintained.
1. Stage: weathering steel begins to grow small rust points, the rust points of ordinary steel plates are relatively loose, and some rust treatment is poor and even rust skin;
3, the second stage of steel plate long rust: weathering steel rust water less, the rust point is small and thick; The rust water of ordinary steel plate is more, and the rust points are larger and thin. Rust column of ordinary steel plate,
Tears are more serious, the bottom of the workpiece has black signs;
4, the third stage of steel plate long rust: weathering steel has a clear and dense rust core layer, and the rust points are tightly bonded to form a protective layer, which can hardly be rusted off by hand; Plain plate removal
The amount of rust is more, and even the whole rust skin is peeled off and rusted through. Weathering steel is biased to reddish-brown, ordinary steel plate is biased to dark color.
Modern weathering steel building curtain wall (3MM) and aluminum plate exterior wall installation is similar, thick layer (5MM and above) weathering steel curtain wall mostly adopts unit mode. landscape
And some simple devices, mostly using direct welding process. Need to pay attention to the following:
1. Corrosion of welding points: the oxidation rate of welding points is the same as that of other materials, which requires welding materials and technology.
2. Water corrosion: weathering steel is not stainless steel, if there is water in the concave position of weathering steel, the corrosion rate will be faster, so do a good job of drainage.
3. Salt-rich air environment: Weathering steel is more sensitive to salt-rich air environment such as Hawaii. In such an environment, the outer protective membrane may not prevent internal entry One step oxidation.
4. Fading: The rust layer on the surface of weathering steel can make the surface of objects near it become rusty.
