News: Development Of Cosco Kansai Paint Fan Of Water - Paint, Coating Level, Products - Building

China's abundant wind energy resources, along with China's booming wind power industry

, Fan Blade Paint Naturally growing demand, but current use Paint Mostly solvent-based system, the construction process, the release of large quantities of solvents, and environmental pollution, ecological health is more negative, which possess their own wind energy Environmental protection Property is extremely inconsistent with our more " Energy Emission reduction "and contrary to the sustainable development strategy. As for the fan blades environmentally friendly paint, although some of the domestic manufacturers have started trying to use, but because of complete dependence on imports, there is high prices, long lead times, especially for construction appears The problems and slow feedback problem, it severely limits apply, so the development and use of environmentally friendly coating fan blades, it is particularly important for our country and it is imperative. fan blade operating environment in general, is the sand large desert or the beach, with an average of about 7,000 hours a year to run, blade the edge of the operating speed about 70 ~ 80km / h, so the amount received up to the general air friction Car 5 ~ 10 times. COSCO Kansai reference to foreign advanced products, the actual situation in our country to develop such a product - Water-based polyurethane finish fan blades. According to Chinese experts epoxy Industry Association, Water-based polyurethane finish fan blades and the supporting performance of the coating is water based polyurethane finish Kansai related indicators, and in the light of current international mainstream fan blade products, and our in which the actual geography and natural environment setting. Fan at the same time meet the following requirements: temperature difference, a vast land of China, the disparity in the South and the northern climate, summer and winter temperature changes significantly, especially in Xinjiang, a long cold winter, short hot summer, spring and autumn climate variability, at the turn of spring, summer and winter in most parts of large diurnal temperature range in some areas up to temperature 70 ~ 80 , so the elastic elongation of the coating, adhesion and mechanical performance requirements of the basic higher. Long sunshine time, China's Xinjiang region higher latitude, long sunshine time, especially in the summer, and therefore more demanding durability. Sand large sand country is a multi-country, especially in Xinjiang, Inner Mongolia, north-west environment even worse, this coating's resistance to wind and sand erosion put forward higher requirements. Acid and alkali resistant. Taking into account the actual atmospheric environment in China and some regions due to environmental pollution caused by acid rain and salt spray in the sea environment, to consider the coating of the acid, alkali, salt and other media properties and resistance to salt spray. According to the China Association of epoxy resin industry experts, the product as a hydroxy acrylate dispersion component, hydrophilic modified HDI trimer as the curing agent component, high elasticity, high wear resistance and high weather resistance of the water polyurethane finish, fully capable of this environment.
