With the increasingly high requirements for anti-corrosion ability and coating effect in metallurgy, construction, automobile, home appliances and other industries, the high-speed development of China's color coated plate industry and continuous hot-dip galvanizing industry of steel strip is promoted, especially the color coated plate manufacturing process saves degreasing (pickling, alkali washing, washing), film-forming (phosphating, passivation, washing) and coating (primer, baking The operation and working time of finish paint) can save the pretreatment cost, coating cost, pretreatment equipment and coating equipment cost, workshop investment cost, etc., improve the processing environment and labor conditions of workers, which are widely welcomed by many manufacturing industries, and further promote the rapid development of color coating industry.

由于带钢连续热镀锌工艺与彩涂板制造工艺，与传统的先加工后涂装工艺有着极大的差别，其采用的脱脂剂与转化液、钝化剂有着特殊的作用与自身的特点，本文特就带钢连续热镀锌与彩涂板的预处理及所用的专用处理剂即板带处理剂的作用与特点作一介绍。

Due to the great difference between the continuous hot-dip galvanizing process and the color coated plate manufacturing process and the traditional process of first processing and then coating, the degreaser, the conversion solution and the passivator used have special functions and their own characteristics. In this paper, the pretreatment of the continuous hot-dip galvanizing process and the color coated plate as well as the functions and characteristics of the special treatment agent used, namely the strip treatment agent, are introduced.

为了把用于带钢连续热镀锌与用于制造彩涂板的基板表面，所附着的油污、锈蚀、灰尘等去除，形成适合于带钢连续热镀锌与涂敷卷材涂料要求的良好基底，以保证热镀锌板与彩涂板，具有良好的耐蚀性与附着力，在热镀锌或涂装材料之前必须进行化学处理。我们把这种带钢连续热镀锌与彩涂板制造过程所用的化学处理剂称之为板带专用处理剂，简称板带处理剂，它包括板带脱脂剂、板带转化液、板带钝化剂三大类。

In order to remove the greasy dirt, rust and dust on the surface of the substrate used for continuous hot galvanizing and color coating of steel strip, and form a good substrate suitable for continuous hot galvanizing and coil coating of steel strip, so as to ensure that the hot galvanizing plate and color coating plate have good corrosion resistance and adhesion, chemical treatment must be carried out before hot galvanizing or coating materials. We call the chemical treatment agent used in the process of continuous hot-dip galvanizing and color coating of steel strip as the special treatment agent for strip, which includes strip degreaser, strip conversion solution and strip passivator.
