Super-hydrophobic anti-icing construction method for fan blades

Abstract

The invention discloses a super-hydrophobic anti-icing construction method for fan blades. The super-hydrophobic anti-icing construction method comprises the steps of spraying preparation, base surface washing, base surface drying, base coat spraying, sprayed surface drying, super-hydrophobic finish coat spraying, field inspection and the like, wherein in the finish coat spraying process, a DSAN coating is adopted as a finish coat, and finish coat air pressure spraying is carried out on the blades through an air compressor. The DSAN super-hydrophobic coating is adopted on the fan blades for spraying treatment, so that the binding power between ice and coating layers is reduced, and blade icing is relieved; and meanwhile, the DSAN coating can increase the temperature of the coating layers,so that the coating layers are easy to deice even in a low-temperature environment, and the two effects are combined to realize the defense of fan icing.

Description

technical field [0001] The invention relates to the field of fan power generation, in particular to a super-hydrophobic anti-icing construction method for fan blades. Background technique [0002] The vast areas south of the Yangtze River in my country and Guizhou and Yunnan in the west are affected by water vapor, cold air from the north and altitude in winter, and mountainous areas are prone to freezing. The surface of the wind turbine is icy, whether it is in the static state of the blade or in the running state; the ice covering of the blade in winter has brought great harm to the operation of the wind turbine. After the blade of the wind turbine is covered with ice, it will destroy the dynamic characteristics and The aerodynamic characteristics, ice quality, stiffness and other properties will affect the material properties of the blades, resulting in overloading and uneven loads on the blades, causing the wind turbines to fail to generate electricity normally, and even l...

[0002] The vast areas south of the Yangtze River in my country and Guizhou and Yunnan in the west are affected by water vapor, cold air from the north and altitude in winter, and mountainous areas are prone to freezing. The surface of the wind turbine is icy, whether it is in the static state of the blade or in the running state; the ice covering of the blade in winter has brought great harm to the operation of the wind turbine. After the blade of the wind turbine is covered with ice, it will destroy the dynamic characteristics and The aerodynamic characteristics, ice quality, stiffness and other properties will affect the material properties of the blades, resulting in overloading and uneven loads on the blades, causing the wind turbines to fail to generate electricity normally, and even leading to serious operational safety accidents. During the ice melting process, there is a runaway The thrown ice hits the safety hazard of nearby people and animals

[0003] Icing the fan blades will cause great harm, therefore, how to perform super-hydrophobic anti-icing treatment on the fan blades to prevent the fan blades from being iced is the technical problem to be solved by the present invention
