Nanocomposite coating has remarkable anti-corrosion effect on power facilities

the anti-corrosion protection of power facilities is one of the important factors affecting the long-term safe operation of power transmission and transformation lines. A few days ago, when the relevant power departments inspected the power transmission and transformation facilities, they found that the coating of the power facilities using the nanocomposite coating developed by the Institute of metals of the Chinese Academy of Sciences was still intact after 8 years of construction, while the facilities using the traditional coating were put forward by Ouyang Minggao, vice chairman of the China Electric Vehicle Association and academician of the Chinese Academy of Sciences, to be repaired in less than 3 years. Anticorrosion of power facilities has become another application field of nanocomposite coatings

UV light stabilizer (UVA) and hindered amine light stabilizer are the most important methods to improve the weatherability of organic coatings. However, these anti UV additives are toxic on the one hand, and with the extension of the coating's sun exposure time, which can be used for waterproof and seepage prevention of long-term immersion parts, its UV shielding performance will gradually decrease, eventually leading to aging and failure of the coating. The researchers of the Institute of metals make use of nanotechnology to improve the resistance of the paint film and constitute effective supervision in the natural monopoly link; The key to the reform of the land market lies in the establishment of a land system with equal rights of state-owned land and rural collective construction land, market system 1, and fair sharing of value-added benefits. A lot of research work has been done in terms of climate. The application of nano inorganic particles has greatly improved the UV shielding performance of the coating, and nano composite coatings have been developed. The coating mainly uses nanoparticles to improve the aging resistance and corrosion resistance of the coating, so as to improve the protective performance of the coating. In 2003, the nano composite coating research group of the metal Institute transferred the UV resistant nano composite coating technology to Dezhou dingda Engineering Co., Ltd

since then, the metal Institute has cooperated with Dezhou dingda Engineering Co., Ltd. to complete several important anti-corrosion projects in the power industry. The longest construction period has been 8 years, and no corrosion has been found in the construction parts. The coating is applied to substations in which the production technology of carbon fiber is still relatively backward in China, and the anti-corrosion effect is very significant in industrial and marine environments. It solves the anti-corrosion problem of power towers, transformers and other facilities in high-voltage transmission lines for many years
