In a high-moisture environment where dust and coastal saltwater are prevalent, the stability of power equipment can be adversely affected. This issue can result in equipment downtime, particularly for transformers, severely disrupting the continuous operation of DC transmission systems. To address this challenge, a superhydrophobic modified fluorosilicone coating was developed, incorporating anti-stain properties. To tackle this issue comprehensively, an orthogonal experiment was conducted, involving six factors and three levels. The study focused particularly on assessing the impact of water-repellent recovery agents, nanofillers, antistatic agents, anti-mold agents, leveling agents, as well as wetting and dispersing agents on the coating's surface tension. The results demonstrate that selecting an appropriate base resin and incorporating well-matched functional additives played a central role in effectively reducing the surface tension of the coating. Consequently, optimized coatings exhibited exceptional resistance to stains and displayed strong corrosion resistance.
在灰尘和沿海咸水普遍存在的高湿度环境中，电力设备的稳定性可能会受到不利影响。这个问题可能导致设备停机，尤其是变压器，严重扰乱直流输电系统的连续运行。为应对这一挑战，开发了一种具有防污性能的超疏水改性氟硅酮涂层。为全面解决这个问题，进行了一项包含六个因素和三个水平的正交实验。该研究特别关注评估拒水恢复剂、纳米填料、抗静电剂、防霉剂、流平剂以及润湿分散剂对涂层表面张力的影响。结果表明，选择合适的基础树脂并加入匹配良好的功能添加剂在有效降低涂层表面张力方面起着核心作用。因此，优化后的涂层表现出卓越的抗污性和强大的耐腐蚀性。
