一、前言金属带材涂塑工艺在联邦德国叫做带材涂塑,而世界其它国家称为卷材涂塑,该工艺是三十年代中期美国开发的。在过去的20年里,这项工艺在世界上得到广泛承认,技术不断完善。与此同时,现代涂料得到很大发展。由于现代涂料的发展和经济上的优越性,使现代化的金属-塑料复合材料生产工艺的广泛应用成为事实。在欧洲,已有60多套钢卷材和铝卷材
I. INTRODUCTION The metal strip coating process is called strip coating in the Federal Republic of Germany, while the other countries in the world call it coil coating. This process was developed by the United States in the mid-1930s. Over the past two decades, this process has been widely recognized in the world and its technologies are constantly improving. In the meantime, modern coatings have been greatly developed. Due to the development of modern coatings and their economic superiority, it is a fact that modernized metal-plastic composite manufacturing processes are widely used. In Europe, there are more than 60 sets of steel coils and aluminum coils
