光固化防腐包覆材料在海上风电装备上适用性研究

The issue of corrosion failure in offshore wind turbine steel pipe piles has become increasingly evident, posing a significant threat to the safe operation of offshore wind energy systems. To address this, the applicability of light - curable anti - corrosive coatings in tropical marine atmospheric conditions was investigated in this study. Firstly, the bending and tensile properties of the light - curable composites were tested. Then, salt spray tests, as well as acid and alkali resistance tests, were carried out on the light - cured sheets. Results showed that the mechanical properties and neutral salt spray (NSS) resistance of the light - curable materials were excellent, and their resistance to neutral salt spray was found to be comparable to that of Anshun armor. In H₂ SO₄ and NaOH solutions, the weight gain rate of the light - curable materials was found to be less than 1.2%, the hardness variation rate was less than 8%, and the bending strength retention rate exceeded 92%, demonstrating its excellent acid and alkali resistance. The light - curable materials met the requirements of anti - corrosion materials for offshore wind power equipment.
