基材前处理的彩涂卷

彩涂板是在薄钢板上涂有机涂料而成的产品。彩涂板具有良好的着色性、成形性、耐腐蚀性和有机化合物的装饰性，以及钢板的高强度和易加工性能。是钢铁工业的深加工产品和高效节能钢材。近年来，优质多用途 彩涂板发展迅速

高耐蚀彩钢板、高成形性彩钢板、耐指纹彩钢板、抗菌彩钢板具有广阔的发展前景。市场上使用的彩涂板主要分为三部分：建筑、家用电器和运输。其中，建筑业所占比例最大，其次是家电业，交通运输业只占一小部分。
彩涂板钢结构车间、机场、仓库、冷库等工商业建筑的屋顶、墙面、门等，一般采用热镀锌钢板和热浸铝锌钢板，经加工成符合聚氨酯要求的瓦楞纸板或夹芯板。家用电器的色板一般以镀锌钢板和冷板为基础，用于生产冰箱、大型空调系统、冷冻机、面包机、家具等。
在运输行业中，镀锌板和冷板是常用的垫板，主要用于油底壳、汽车内饰件等，如果作为基材的镀锌钢板在生产后没有直接进入彩涂工艺，在运输过程中可能会造成生锈（白锈）、灰尘等污染。如果这些不能去除，会影响彩色涂层的质量。彩涂辊成品的质量和各项理化性能与前处理密切相关。另外，镀锌生产后，为了防止生锈和油污，这些油也应在彩涂生产前清除掉。

Color coated roll is a product obtained by applying organic coating on thin steel plate. It has good colorability, formability, corrosion resistance and decoration of organic compounds, as well as high strength and easy processing performance of steel plate. It is a deep-processing product of iron and steel industry and high-efficiency energy-saving steel. In recent years, high quality and multi - purpose color coated steel plate has developed rapidly

High corrosion resistant color steel plate, high formability color steel plate, fingerprint resistant color plate and antibacterial color steel plate have a bright future. The market use of color coated board is mainly divided into three parts: construction, household appliances and transportation. Among them, the construction industry accounts for the largest proportion, followed by the household appliances industry, and the transportation industry only accounts for a small part.
Generally, hot-dip galvanized steel sheet and hot-dip aluminum zinc steel plate are used as base plates for building roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport, warehouse and freezer after being processed into corrugated board or sandwich board conforming to polyurethane. The color plate of household electrical appliances is generally based on galvanized steel and cold plate, which is used to produce refrigerators, large air conditioning systems, freezers, bakers, furniture, etc.
In the transportation industry, zinc plating and cold plate are commonly used as base plates, mainly used for oil pan, automobile interior parts, etc. If the galvanized steel sheet as the base material is not directly into a color coating process after production, it may cause rust (white rust), dust and other pollution during transportation. If these can not be removed, it will affect the quality of color coating. The quality and all physical and chemical properties of the finished color coated roll are closely related to the pretreatment. In addition, after galvanizing production, in order to prevent rust and oil, these oil should also be removed before color coating production.
