At present, the materials are divided into three main types of plastic products, aluminum products and enamel products.

Because of the specificity of the power grid identification plate, the power grid identification plate needs to be fixedly hung on parts such as an outdoor distribution line telegraph pole, a power transmission line iron tower and substation equipment throughout the year, and can lead to fading and blurriness of fonts and pattern colors on the surface under the comprehensive actions of solar radiation, repeated high-temperature and high-humidity experiences, day-night temperature difference, adhesion of air dust pollutants and the like, and finally only the identification plate bottom plate is left to lose the identification effect.

Because the power grid signboard is fixedly hung on the parts of an outdoor distribution line telegraph pole, a power transmission line iron tower, transformer substation equipment and the like throughout the year, the power grid signboard is subjected to complex reaction to fade under the comprehensive actions of solar radiation, high temperature and high humidity, day and night cold and hot temperature difference, adhesion of air dust pollutants, corrosion of pH acidic substances and the like for a long time, and the power grid signboard is a main cause of fading and blurring of the power grid signboard. At present, no technical measures exist to fundamentally solve the problem of fading and blurring of the power grid signboard. Therefore, research and development of the more effective anti-fading fuzzy treatment preparation for the signboard can effectively reduce the occurrence of fading condition of the signboard, prolong the service life of the power grid signboard, improve the reliability of the power grid signboard, and have important practical significance for improving the efficiency of maintenance and repair work of the power grid, improving the reliability of a power supply system and the like.
