彩涂钢板，又称彩涂板，在工业上又称彩钢板或彩钢板，是以冷轧钢板、镀锌钢板或铝板为基板，经表面预处理后，再连续涂布，最后烘烤冷却而成的产品。彩涂板重量轻、外形美观、防腐性能好，广泛应用于建筑、造船、汽车制造、家具、电器、装饰等行业。
自1935年美国建立第一条连续涂层钢生产线以来，彩色涂层钢得到了广泛的应用。目前，其生产方式基本上采用溶剂涂布辊涂的生产工艺。生产工艺的优点是可以均匀、快速地进行涂布，实现规模化生产，从而满足彩涂板经济发展的大需求。然而，溶剂型辊涂法存在着严重的污染问题，其中含有挥发性苯、甲苯、二甲苯、乙酸丁酯、丙酮等刺激性有毒物质。自2016年实施“史上大气污染防治法”以来，彩涂板行业备受关注。为什么污染这么严重？如何改进和避免？我们应该从它自身的特点和生产工艺入手。
如何应对历史上严重的空气污染防治法
据统计，目前市场上有600多种彩涂板。然而，无论品种如何变化，彩涂板的生产工艺是相同的，差异主要是由于材料的不同。
彩涂板的典型生产工艺如下：
入口卷小车卷取→开卷机→二辊夹送机→剪头机→焊机→张力辊→入口立活套→纠偏辊→张力辊→碱洗装置→洗涤装置→碱洗装置→热水冲洗装置→热风干燥装置→立式涂布机→立式涂布炉→张力辊→纠偏辊→一次涂布机→一次涂布固化炉→水冷装置→热风烘干机→张力辊→精涂机→精涂固化炉→纠偏辊→水冷装置→热风烘干机→张

Color coated steel plate, referred to as color coated plate, also known as color steel plate or color plate in the industry, is a product made of cold-rolled steel plate, galvanized steel plate or aluminum plate as the base plate, after surface pretreatment, then coating in a continuous way, and finally baking and cooling. With light weight, beautiful appearance and good anti-corrosion performance, color coated plate is widely used in construction, shipbuilding, vehicle manufacturing, furniture, electrical, decoration and other industries.

Since 1935, the first continuous coated steel line was established in the United States, color coated steel has been widely used. At present, its production mode basically uses the production process of solvent coating roller coating. The biggest advantage of the production process is that it can be coated uniformly and at high speed to achieve large-scale production, so as to meet the large demand of the economic development for color coated plates. However, there are serious pollution problems in the way of roller coating with solvent coating, which contains volatile benzene, toluene, xylene, butyl acetate, acetone and other irritant toxic substances. Since the implementation of "the most stringent air pollution prevention and control law in history" in 2016, the color coated plate industry has received close attention. Why is the pollution so serious? How can we improve and avoid it? We should start from its own characteristics and production technology.
How to deal with the most severe air pollution prevention and control law in history
According to statistics, there are more than 600 types of color coated plates on the market. However, no matter how the variety changes, the production process of color coated plate is the same and the difference is mainly due to the different materials.
The typical production process of color coated plate is as follows:
Entrance coil car winding → uncoiler → two roller pinch machine → end trimming shear machine → welding machine → tension roller → entrance vertical looper → deviation rectifying roller → tension roller → alkali washing device → scrubbing device → alkali washing device → hot water rinsing device → hot air drying device → vertical coating machine → vertical coating furnace → tension roller → deviation rectifying roller → primary coating machine → primary coating curing furnace → water cooling device → hot air dryer → tension roller → fine coating machine → fine coating curing furnace → deviation rectifying roller → water cooling device → hot air dryer → Zhang
