一、前言有机涂层钢板自三十年代在美国问世以来,发展十分迅速,目前已发展成为冶金与化工相结合的重要金属板材。据报导,目前世界上已拥有200余条有机涂层钢板生产作业线,年生产能力为1000万吨,所用涂料达500余种。有机涂层钢板所用底材,一般为0.3～2毫米的镀锌钢板及冷轧钢板,也有用镀铝钢板,镀锡钢板及铝板。涂装生产线最高速度达240米/分,使用领域主要是建筑业,作为
I. Introduction Organic coating steel plate since the advent of the United States in the thirties, the development is very rapid, has now developed into an important metallurgical and chemical combination of sheet metal. It is reported that at present the world has more than 200 organic coated steel production line, the annual production capacity of 10 million tons, the use of more than 500 kinds of paint. Organic coated steel substrate used, usually 0.3 to 2 mm of galvanized steel and cold-rolled steel, but also useful aluminum plate, tin plate and aluminum. Painting production lines up to a maximum speed of 240 m / min, the use of the field of construction industry, as
