Abstract

The invention discloses a method for employing a copper-steel composite board to prevent adhesion corrosion of marine organisms and a preparation method for the copper-steel composite board. The corrosion-preventing method comprises: employing the copper-steel composite board or a copper-steel-copper composite board to coat the housing of a to-be protected apparatus, and attaching the steel layer to the to-be protected apparatus when the copper-steel composite board is employed. The preparation method of the composite board comprises the following steps: (1) performing surface texturing; (2) performing composite rolling; (3) performing diffusion heat processing; (4) performing beforehand finish rolling; (5) performing heat treatment for target performances; and (6) eliminating the yield ratio through flattening. By utilizing the bacteriostasis property of the surface copper of the copper-steel composite board, the copper-steel composite board is used to coat see-soaked bottom of a ship, a tension column of an offshore oil drilling platform and to-be protected parts of oceaneering facilities, and gives play to marine organism corrosion resistant effect on ship shells, the tension column of the offshore oil drilling platform and all oceaneering facilities wetted by seawater.

Description

technical field [0001] The invention relates to a method for preventing marine organisms from attaching and corroding and a preparation method for its material. Background technique [0002] Marine fouling organisms, also known as marine fouling organisms, refer to animals, plants and microorganisms that grow on the bottom of ships and on the surface of all facilities in the sea. The phenomenon of growing organisms on the bottom of ships and underwater facilities is called biofouling, and the prevention of biofouling is also called anti-fouling. [0003] The attachment of marine organisms to the underwater parts of ships and sea-immersed facilities will firstly reduce the speed of the ship and increase fuel consumption. According to statistics, when the hull fouling rate reaches 5%, the fuel consumption will increase by more than 40%, and the economic loss will be huge; secondly , It will also increase the corrosion damage of ships and submerged underwater facilities, signi...
