当前除了汽车工业以外,金属表面涂饰的趋势正朝着使用聚脂粉末进行静电喷涂的方向发展。这种趋势在美国等工业发达的国家甚为明显,特别在西欧,粉末的消耗量已达世界粉末消耗量的一半以上(1984年总量117,500吨中的62,500吨)。近年来,聚脂粉末耗量的增长率已达20%,在不远的将来,聚脂粉末的消耗量更 In addition to the current automotive industry, the trend of metal surface finishing is moving toward electrostatic spraying using polyester powder. This trend is evident in industrially developed countries such as the United States. Particularly in western Europe, powder consumption has reached more than half of world powder consumption (62,500 tons out of 117,500 tons in 1984). In recent years, the growth rate of the consumption of polyester powder has reached 20%. In the near future, the consumption of polyester powder is even greater.
