Description

Technical field: [0001] The invention relates to a seawater circulation system for testing the performance of marine antifouling coatings, in particular to a seawater circulation system with simple structure, easy operation, low test cost, and capable of dynamically testing the influence of seawater flow on the adhesion of fouling organisms, so as to comprehensively and accurately Seawater circulation system for evaluating the surface performance of antifouling materials. Background technique: [0002] In the process of development and utilization of marine resources, the problem of seawater corrosion and the problem of adhesion and fouling of marine organisms have always been two major problems facing human beings. Marine fouling organisms, also called marine attachment organisms, are the general term for animals, plants and microorganisms that grow on the surface of marine underwater facilities such as ships, such as barnacles, algae, fungi, and shellfish. The attachment of ma...

Problems solved by technology

In the past, there are mainly two traditional evaluation methods for the antifouling performance of antifouling materials: one is to indirectly reflect the antifouling performance by measuring the exudation rate of active ingredients of antifouling materials, and this method is only applicable to the exudation rate of "poisonous materials". The evaluation of antifouling materials as an antifouling method is not suitable for the evaluation of antifouling materials that use the special properties of the coating surface as an antifouling method, so this method has limited application and poor universality; Establish an experimental base, and directly evaluate its antifouling performance through real sea hanging panels (antifouling material test panels). This method has a long experimental cycle and high risks; the above two traditional evaluation methods are difficult to meet the initial screening and optimization work of antifouling material development

For this reason, there are currently scientific research institutions using indoor biological methods to evaluate the effectiveness and sustainability of antifouling coatings and their main components (antifouling agents, functional resins), but they only test the ions of antifouling coatings in a static state. It is difficult to comprehensively and accurately evaluate the antifouling performance of the surface of antifouling materials
