Currently, most ships have metal hulls. In the marine environment, metal is affected by seawater temperature, seawater salinity, marine atmospheric temperature, and marine atmospheric humidity, and the degree of corrosion is very serious. Corrosion not only reduces the strength of the ship's steel structure, but also shortens the service life of the ship. It will increase the sailing resistance, reduce the speed, and affect the performance more seriously. Once perforation or cracking occurs, it will also lead to the occurrence of an average accident and cause astonishing losses. This has attracted great attention from anti-corrosion experts at home and abroad, and actively research and explore various protective technical methods and measures to solve metal corrosion.

The rust of the ship deck is mainly due to the chemical corrosion of the ship's steel plate when it is exposed to the air and immersed in seawater for a long time. Electrolytic substances such as acid, alkali and salt will electrochemically corrode the steel material. These are the main reasons for the corrosion of the steel material. , and ship rust removal and paint maintenance is a regular task, ship deck shot blasting machine is currently the more advanced ship deck rust removal equipment and cleaning program.
