Surface treatment technology of T-shaped component for ship

Abstract

The invention belongs to the field of surface treatment of T-shaped components of ships, and particularly discloses a surface treatment technology for a T-shaped component of a ship. The technology includes the following steps that pretreatment of the surface of the T-shaped component is performed, and pretreatment includes degreasing treatment, surface refining treatment and rusting treatment; protective film treatment is performed and includes spraying of a protective inner layer film and coating of the protective inner layer film; anti-corrosion liquid treatment is performed, specifically,the treated component is immersed in an anti-corrosion tank containing the anti-corrosion liquid, and the temperature of the anti-corrosion tank is kept at 20-20 DEG C for 5-20 min; and after the component treated by the anti-corrosion liquid is dried, anti-corrosion finish paint is sprayed to the surface of the component, and surface treatment is completed. According to the technology, the T-shaped component is subjected to surface pretreatment, protective film treatment and anti-corrosion liquid treatment, so that multiple layers of compact protective films are formed on the surface of the component, the corrosion prevention time is prolonged, the relatively good corrosion prevention purpose is achieved, and the characteristics of seawater corrosion resistance and the like of the T-shaped component are achieved.

Description

Technical field[0001]The invention relates to the related field of surface treatment of T-shaped members of ships, in particular to a surface treatment process of T-shaped members for ships.Background technique[0002]Under the form of global economic integration, international trade activities have become more frequent, and with the increase in international trade, the demand for maritime transportation has increased, and the single-time operating cost remains high, which has affected the profits of major shipping companies. One of the main reasons for this is that in order to reduce operating costs, various shipping companies prefer larger ships when choosing ship types. For ships with larger ship types, the strength of their hull structures often requires a large number of T-shaped materials (components). ) For strengthening, therefore, a large number of T-sections (components) are used as indispensable materials for the construction of various large ships.[0003]Ships sailing on th...

Problems solved by technology

[0003] Ships sailing on the ocean, because the marine environment is a specific and extremely complex corrosion environment, the seawater contains a large amount of salt and other substances, which will cause various corrosions on the metal components in the environment, especially the T-shaped components and destructive effects, affecting its service life, so a surface treatment process is needed to treat its surface to prolong its service life and corrosion resistance
