彩钢板（又名：彩板、彩色涂层钢板）是以冷轧钢板和镀锌钢板为基板，经过表面预处理（脱脂、清洗、化学转化处理），以连续的方法涂上涂料（辊涂法），经过烘烤和冷却而制成的产品。

Color coated steel plate (also known as color coated steel plate or color coated steel plate) is a product made from cold-rolled steel plate and galvanized steel plate as substrates, which undergo surface pretreatment (degreasing, cleaning, chemical conversion treatment), continuous coating (roller coating method), baking and cooling.

涂层结构有二涂一烘、二涂二烘等，免维护使用年限根据环境大气不同可为10－30年。

The coating structure includes two coatings and one drying, two coatings and two drying, etc. The maintenance free service life can be 10-30 years depending on the environment and atmosphere.

常见的二涂二烘型连续彩色涂层机组工艺流程主要生产工序为：开卷机-------缝合机------压辊------涨力机----开卷活套-----碱洗脱脂------清洗----烘干-------钝化-------烘干------初涂-------初涂烘干------面漆精涂------面漆烘干------风冷降温------收卷活套-----收卷机-----（下卷打包入库）。

The main production process of the common two coating and two drying continuous color coating unit is as follows: unwinding machine - sewing machine - pressure roller - tension machine - unwinding loop - alkali washing and degreasing - cleaning - drying - passivation - drying - initial coating - initial coating drying - topcoat fine coating - topcoat drying - air cooling cooling - winding loop - winding machine - (lower coil is packaged and stored).

双面二涂二烘彩色涂层钢板的涂层结构，如上图所示

The coating structure of double-sided two coated and two baked color coated steel plate is shown in the above figure

上表面二涂二洪，下表面涂一层的彩色涂层钢板的涂层， 如上图所示 （此类背面漆一般不宜当正面使用）

The upper surface is coated with two coats of paint, and the lower surface is coated with a layer of color coated steel plate coating, as shown in the above figure (this type of back paint is generally not suitable for use as the front)

彩色涂层钢板是以冷轧钢板，电镀锌钢板、热镀锌钢板或镀铝锌钢板为基板经过表面脱脂、磷化、铬酸盐处理后，涂上有机涂料经烘烤而制成的产品。彩色涂层钢板的常用涂料是聚酯(BHP XRW涂覆系统，宝钢JZ，韩国PGS，台湾PE )，其次还有硅性树酯(PSS)，氟树脂(PVDF)等，涂层结构分二涂一烘和二涂二烘，涂层厚度一般在表面20-25μ，背面8-10μ。彩色涂层钢板通常引用的标准是美国ASTM A527(镀锌)、ASTM AT92 (镀铝锌)，日本JIS G3302，欧洲EN/0142，韩国KS D3506，宝钢

Color coated steel plate is a product made from cold-rolled steel plate, electrogalvanized steel plate, hot-dip galvanized steel plate, or aluminum zinc plated steel plate as the substrate, which is degreased, phosphated, and chromated on the surface, coated with organic paint, and baked. The commonly used coatings for color coated steel plates are polyester (BHP XRW coating system, Baosteel JZ, South Korea PGS, Taiwan PE), followed by silicone resin (PSS), fluororesin (PVDF), etc. The coating structure is divided into two coating and one drying, and the coating thickness is generally 20-25 on the surface μ， Back 8-10 μ。 The standards commonly cited for color coated steel plates are ASTM A527 (galvanized) and ASTM AT92 (aluminum zinc plated) from the United States, JIS G3302 from Japan, EN/0142 from Europe, KS D3506 from Korea, and Baosteel
