随着冶金、建筑、汽车、家电等行业对防腐能力和彩涂卷涂装效果的要求越来越高，推动了我国彩涂卷行业和钢带连续热镀锌行业的高速发展，特别是彩涂卷制造业工艺节约除油（酸洗、碱洗、水洗）、成膜（磷化、钝化、水洗）和涂装（底漆、烘烤面漆的操作和工作时间）可节约预处理成本、涂装成本、预处理设备和涂装设备成本、车间投资成本等。，改善加工环境和工人劳动条件。它受到许多制造业的广泛欢迎，进一步推动了彩色涂料行业的快速发展

由于连续热镀锌工艺与彩涂卷制造工艺、传统的先加工后涂装工艺有很大的区别，所使用的脱脂剂、转化液和钝化剂具有特殊的功能和各自的特点。介绍了连续热镀锌工艺和彩涂卷的预处理，以及所用的专用处理剂即带钢处理剂的作用和特点。
为了清除带钢连续热镀锌和彩涂用的基板表面的油污、铁锈和灰尘，形成一个良好的适合带钢连续热镀锌和彩涂的底座，保证热镀锌板和彩涂具有良好的耐腐蚀性和附着力，热镀锌或涂层材料前必须进行化学处理。我们把带钢连续热镀锌和彩涂工艺中使用的化学处理剂称为带钢专用处理剂，简称为带钢处理剂。包括带材脱脂剂、带材转化液和带材钝化剂
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 color coated coil industry and continuous hot-dip galvanizing industry of steel strip in China is promoted, especially the color coated coil 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. It is widely welcomed by many manufacturing industries and further promotes the rapid development of color coating industry.
Due to the great difference between the continuous hot galvanizing process and the color coated coil 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 galvanizing process and the color coated coil and the functions and characteristics of the special treatment agent used, namely the strip treatment agent, are introduced.
In order to remove the oil, rust and dust on the surface of the base plate used for continuous hot galvanizing and color coating of steel strip, and form a good base suitable for continuous hot galvanizing and coating of steel strip, so as to ensure that the hot galvanizing plate and color coating 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 continuous hot-dip galvanizing and color coating process of steel strip as the special treatment agent for strip, which is called strip treatment agent for short. It includes strip degreaser, strip conversion liquid and strip passivator.
