Surface Treatment Methods for Ship Plates in Steel Industry

TAGS: plates | surface | steel |

Surface treatment is an important step in the production of ship plates in the steel industry. It not only improves the appearance of the plates but also enhances their performance and durability. There are various surface treatment methods available, and the following are some of the most common ones:

1. Shot blasting: This method involves blasting the surface of the plates with steel shots to remove rust and other impurities. It also creates a rough surface that increases the adhesion of the coatings.

2. Pickling: Pickling is a chemical method that involves immersing the plates in an acid solution to remove oxides and scale. The acid can be hydrochloric acid or sulfuric acid, depending on the type of steel and the level of impurities.

3. Painting: Painting is a common surface treatment method that involves applying a layer of paint or coating to the surface of the plates. This not only improves the appearance of the plates but also provides protection against corrosion and abrasion.

4. Passivation: Passivation is a chemical treatment method that involves immersing the plates in a solution containing nitric acid to remove iron and other impurities from the surface. This method is suitable for stainless steel plates.

5. Galvanizing: Galvanizing is a process that involves coating the surface of the plates with a layer of zinc to provide protection against corrosion. The plates are immersed in a bath of molten zinc or sprayed with zinc powder.

there are various surface treatment methods available for ship plates in the steel industry, and the choice of method depends on the type of steel, the level of impurities, and the desired performance and appearance of the plates.
