日本中田涂料公司最近发明了一种金属表面处理技术,可形成一层8微米厚高抗腐蚀性涂层,易于润滑,而且耐磨损。处理时,首先用三氯乙烯蒸汽清洁原材料表面,除去油脂,再将具有高抗腐蚀效果的由锌和铁锌合金组成的涂料涂于金属表面,形成牢固结合的表膜。然后,在一种含铬酸的特殊处理溶液中浸一浸,从而形成铬酸盐膜。这种铬膜技术省去了传
Nakata Paint Co., Ltd. of Japan recently invented a metal surface treatment technology to form a layer of 8-micron thick high corrosion-resistant coating, easy to lubricate, and wear-resistant. Treatment, the first with trichlorethylene vapor cleaning the surface of raw materials to remove grease, and then have a high corrosion resistance of zinc and iron-zinc alloy coating composed of metal applied to the surface to form a strong combination of the film. Then, it is immersed in a chromic acid-containing special treatment solution to form a chromate film. This chrome film technology eliminates the need for transmission
