Degreasing Technology of A588 Weathering Steel Plate

A588 weathering steel is one of the most exposed and destructive products with compositional and chemical composition requirements. During use, degreasing is one of the most critical treatments for further processing. The following introduces the degreasing process of A588 weathering steel plate.

A588 weathering steel plate degreasing technology

1. Immersion degreasing: This method is suitable for small and medium sized parts. The degreasing fluid is to immerse parts which made from A588 weathering steel plate in the degreasing tank, heat them to the required temperature, heat themfor a certain period of time, and then remove the deteriorated oil and organic matter on the surface of the parts by immersion.

2. Ultrasonic degreasing: This degreasing process uses high-frequency ultrasonic waves to form millions of tiny bubbles in the degreasing liquid. The bubbles oscillate and compress rapidly, generating heat in the liquid and friction on the surface of the part. The surface friction created by the continuous cycle further accelerates the surface of the part. The surface tension of the dirt layer is reduced, and the adsorption of dirt on the surface of the parts is reduced, thereby achieving the effect of degreasing.

3. Foam degreasing: Foam degreasing is to make degreasing fluid into foam, and then spray it evenly onto the surface of the parts. It plays the role of lifting and separating oil spots, and has strong dirt removal ability. Foam degreasing can be divided into dry foam degreasing and wet foam degreasing.

After the A588 weathering steel plate is degreased, in order to avoid rust and corrosion, it should be treated with anti-rust oil to obtain the surface pattern effect required for further processing and assembly.
