彩涂卷材料共分爲五类:包装类、家电类、建材类、光学材料及装饰材料。在进行彩涂卷线生产时,首先要考虑的三个基本要素为:质量、产品的多样
化、高产,随着彩涂卷需求量的增加,对这三个要素的要求更加严格。影响涂层机组生产的因素很多,如带钢预处理、涂机和固化炉等,但最关键的两
个因素是涂机和固化炉。预处理工艺的主要目的是除去带钢表面的油脂和杂质,并通过钝化,在钢板表面形成一层化学转化膜,以提高涂层与带钢基板

Color coating and roll materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. In
the production of color coating rolling line, the first three basic elements should be considered are: quality, product diversification and high yield. With the
increase of the demand for color coating rolling, the requirements for these three elements are more strict. There are many factors affecting the production of
coating units, such as strip pretreatment, coating machine and curing furnace, but the two most critical factors are coating machine and curing furnace. The
main purpose of the pretreatment process is to remove the grease and impurities on the surface of the strip steel, and to form a chemical conversion film on
the surface of the steel plate through passivation to improve the adhesion between the coating and the strip substrate and the corrosion resistance of the
strip steel.
