Embodiment 1

[0022] An anti-icing fan blade coating suitable for alpine regions, characterized in that it includes a composite coating 1 of silicon dioxide and polytetrafluoroethylene and a branched polyfluorosilane coating 2, the silicon dioxide and The polytetrafluoroethylene composite coating 1 is located on the blade surface, and the branched polyfluorosilane coating 2 covers the outer side of the silicon dioxide and polytetrafluoroethylene composite coating 1 .

[0023] In the embodiment, the thickness of the silicon dioxide and polytetrafluoroethylene composite coating 1 is controlled at 20-30 μm.

Embodiment 2

[0025] An anti-icing fan blade coating process suitable for high cold areas, characterized in that it includes the following steps:

[0026] Step 1: Washing: First, rinse the surface of the blade with a water gun to wash off the floating soil and foreign matter on the surface of the blade, and then dry the surface of the blade with a wiping cloth. When wiping, wipe it in the same direction one by one in an orderly manner;

[0027] Step 2: Degreasing and pickling: For ordinary leaves, it is recommended to brush with defatting acid to remove the grease on the surface of the leaves. For the leaves with metal reinforcing ribs or other metal fixing devices, use brushing or spraying absolute ethanol to clean the leaves. Remove the grease, and finally rinse the leaf surface with a water gun to remove the residual ethanol on the leaf surface, and finally dry the leaf surface with an air gun;

[0028] Step 3: Preparation of silica and polytetrafluoroethylene composite coating 1: place ...

Abstract

The invention discloses an anti-icing fan blade coating suitable for alpine regions and a process thereof. The anti-icing fan blade coating suitable for the alpine regions is characterized by comprising a silicon dioxide and polytetrafluoroethylene composite coating and a branched polyfluorosilane coating, and the silicon dioxide and polytetrafluoroethylene composite coating is located on the surface of a blade. The branched polyfluorosilane coating covers the outer side of the silicon dioxide and polytetrafluoroethylene composite coating. According to the anti-icing fan blade coating suitable for the alpine regions and the process thereof, the problem that materials and performance of a wind generating set are changed due to icing is solved, the problem that equipment use is affected due to the fact that fatigue loads are increased is solved, guarantee is provided for safe and long-time operation of the wind generating set, and the problem of equipment failures caused by blade icing is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of fan blade coatings, and in particular relates to a coating process for anti-icing fan blades in alpine regions. Background technique [0002] The blades of wind turbines work in the air environment for a long time, and there are a lot of water droplets in the air, which do not flow through the surface of the blades like gas molecules, but stay on the surface and condense into ice. The trajectory of the water droplets is speed and water. Function of bead diameter (mass). In winter, when the surface of the blade contains supercooled water droplets or when there is freezing fog, ice will form on the surface. This icing can significantly restrict air flow through the blades, causing performance loss and potentially causing equipment failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-icing fan blade coating process suitable for high...
