本课题针对钢铁因腐蚀造成使用寿命短、浪费严重，日趋严重的大气雾霾问题急需缓解问题，开发高耐蚀镀层技术与除雾霾抗菌涂层技术。围绕资源节约型高耐蚀镀层技术与除雾霾抗菌涂层技术开发等方面开展一系列研发，并建立示范工程，支撑项目目标“镀层厚度减少 30%，钢材寿命提高 1 倍以上，实现可见光 24 小时内雾霾去除率≥60%、抗菌率≥90%。

This topic aims at the short service life and serious waste of steel due to corrosion, and the increasingly serious atmospheric haze problem urgently needs to be alleviated, and the development of high corrosion-resistant coating technology and anti-bacterial coating technology for haze removal. Carry out a series of research and development on resource-saving high corrosion resistant coating technology and anti-smog antibacterial coating technology development, and establish demonstration projects to support the project goal "coating thickness is reduced by 30%, steel life is more than doubled, and visible light 24 Haze removal rate ≥60%, antibacterial rate ≥90% within hours.
