Study on sand blasting performance of wind turbine blade coating

At present, most of the wind power equipment in CHINA are located in high wind and sand areas, and the wind and sand often cause serious wear of the blades and reduce the design life of the blades. Therefore, many manufacturers have studied the wind and sand resistance of blade coatings in response to this situation. Sun Yu and Sun Tairong also carried out experimental research. In their paper "Study on the Wind and Sand Resistance of Wind Turbine Blade Coatings by Sandblasting with Stone Impact Instruments", MTG stone impact instruments and ISO standard sand were used as abrasives to test the resistance of blade coatings. The wind-sand performance research experiment was carried out, and the relationship between the elongation rate of the coating film and the sand impact weight loss was analyzed by combining the taber abrasion data, and it was found that this method is more scientific, accurate and fast in evaluating , which is a good method It is a good method to evaluate the wind-sand erosion test of coatings.
