1.前言 最近建筑材料和食品罐头材料中除了镀锡钢板(白铁皮)和镀锌钢板之外,还大量生产新的产品。这些产品就是将钢板表面用金属和塑料保护的一种叫做表面处理钢板,但它不如镀锡钢板和镀锌钢板美观,为了获得优异的耐蚀耐热性,需要迅速地发展这些新的产品。 钢板进行表面处理的 1. INTRODUCTION Recently, in addition to tinplate (tinplate) and galvanized steel, building materials and food canning materials have been mass-produced. These products are the surface-treated steel plates, which are protected by metal and plastic, but are not as good as tin-plated steel plates and galvanized steel plates. In order to obtain excellent corrosion and heat resistance, these new products need to be rapidly developed. Steel surface treatment
