光固化防腐包覆材料在海上风电装备上适用性研究

Applicability of Light-Curable Anti-Corrosion Coatings for Offshore Wind Power Equipment

海上风电钢管桩的腐蚀失效问题凸显,对海上风电的安全运行构成了严重的危害。为此,研究了光固化防腐包覆材料在热带海洋大气环境中的适用性。首先,对光固化复合材料进行弯曲和拉伸性能试验;然后,对光固化片材分别进行盐雾试验和抗酸碱试验。结果表明:光固化材料的力学性能和抗中性盐雾性能优异,其抗中性盐雾性能与安盾护甲相当;在H_(2)SO_(4)、NaOH溶液中,光固化材料的增重率小于1.2%,硬度变化率小于8%,弯曲强度保留率超过92%,光固化材料具有非常优异的抗酸碱性能。光固化材料满足海上风电装备防腐材料的需求。

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 mechani-cal 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 H_(2)SO_(4)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%,demonstra-ting its excellent acid and alkali resistance.The light-curable materials met the requirements of anti-corrosion materials for offshore wind power equipment.
