In the long-term field research of Zhisheng Weihua anti-ice coatings, it was found that the surface icing phenomenon of the transmission line was affected by the important factor of temperature, the surface characteristics of the icing surface, especially the surface energy and the adhesion of the surface to ice. And the hydrophobicity of the surface has a greater impact on the icing phenomenon. Under the action of adsorption force, ice crystals can adhere to the surface of icing and deposit continuously. The size of this adsorption force depends on the surface wettability between the ice crystal and the icing surface. If it is a hydrophobic surface with low surface energy, It can be a non-wetting state between the ice crystal and the surface, which can greatly reduce the adsorption force on the ice crystal, thereby effectively preventing icing. The results of Zhisheng ZS-611 anti-ice coating test also prove that in order to reduce the adhesion of surface to water and prevent icing, the contact angle of surface to water is more than 90Â°, and the surface energy must be lower than 25x10-3N/m.
