Papers by Keyword: Antifouling Coating

Abstract: Equipment, pipelines, hydraulic structures located in the water are covered with a layer of fouling organisms, which is accompanied by a deterioration in operating parameters and increased corrosion of structural materials. Most anti-fouling coatings contain some type of toxins, the gradual release of which from the coating into the water should lead to the death of the fouling organisms. A promising antifouling coating intended for use in an aquatic environment is a combined metal-polymer coating, the composition and application technology of which were developed by the company LLC TSZP. On the studied coating, neither in the zone of variable wettability, nor in the zone of complete immersion, firmly fixed zebra mussels were not found, and single specimens on individual samples had very weak fixation.

Abstract: To develop new non-toxic antifouling coating, some fouling-release(FR) coatings based on fluoro-copolymer and silicone polymer were formulated. Coatings specimens were rotated in a laboratory device at different simulating speeds of a ship for some periods. The film thickness, surface roughness, water contact angle of all coatings were measured and investigated. The relationship between the performance and testing time, and the effect of simulating speed on the performance were studied and discussed. The research results show that the time spent on evaluating the performance of ship antifouling coatings was shortened. The film thickness of all coatings decreases with test time. FR antifouling coatings surface roughness increase slowly, and their surface contact angle decrease gradually with time. Increasing of the simulating speed will accelerate the surface of all the coatings trend to rougher, increase the ablation rate of the coatings and the change of water contact angle of FR coatings.
