Description

Technical field: [0001] The invention relates to a testing device for marine antifouling materials, in particular to a device with simple structure, easy operation, low testing cost, capable of testing and analyzing the attachment of marine fouling organisms in both static and dynamic states, so as to comprehensively and accurately evaluate A marine antifouling material testing device for the antifouling performance of the material surface. Background technique: [0002] In the development and utilization of marine resources, the corrosion of seawater and the fouling of marine organisms have always been two major problems faced by human beings. Marine fouling organisms, also known as marine fouling organisms, are a 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 marine organisms will increase the sailing resistance of the ship, block...

Problems solved by technology

In the past, there are mainly two traditional evaluation methods for the antifouling performance of antifouling coatings: one is to indirectly reflect the antifouling performance by measuring the exudation rate of active ingredients in antifouling coatings. The evaluation of antifouling coatings as an antifouling method is not suitable for the evaluation of antifouling coatings that use the special properties of the coating surface as an antifouling method. Therefore, the use of this method is limited and its universality is poor; The docks and others have established experimental bases to directly evaluate the antifouling performance of the actual sea-hanging panels (antifouling coating test panels). This method has a long experimental period and high risks; the above two traditional evaluation methods are difficult to meet the initial screening of antifouling material development Merit job

For this reason, at present, indoor biological methods are used to evaluate the effectiveness and sustainability of antifouling coatings and their main components (antifouling agents, functional resins), but they only test the ion leakage of antifouling coatings in a static state. rate, antibacterial activity and amount of fouling organisms, it is difficult to comprehensively and accurately evaluate the surface antifouling performance of antifouling materials
