彩涂卷初涂机的主要作用是什么? 


现代国内外的彩涂机组对于带材的涂层施工,基本上都采用两次涂层和两次烘干的过程,即两涂两烘工艺,其中用于底漆(即涂敷于钢带表面的第一层漆膜)施工的涂机被称作初涂机。

初涂机主要用于带材正面和背面底漆的涂敷,同时根据生产工艺的要求,初涂机也可为带材的印花提供底漆。

一般来说,底涂层的厚度都比较薄,因此初涂机的底涂头和面涂头均采用二辑式涂头布置。另外影响到涂层表面质量的因素中,主要有涂料的黏度、稀释剂的比例以及湿膜的厚度,其中对涂机来说,通过调整涂头各辊之间、涂敷辊与支撑辊之间的辊缝压力,可以控制涂层的湿膜厚度。

For the coating construction of strip, modern color coating machines at home and abroad basically adopt the process of two coating and two drying, that is, two coating and two drying process. The coating machine used for primer (that is, the first layer of paint film applied on the surface of steel strip) construction is called primary coating machine.
The primary coating machine is mainly used for the coating of the primer on the front and back of the strip. At the same time, according to the requirements of the production process, the primary coating machine can also provide the primer for the printing of the strip.
Generally speaking, the thickness of the primer is relatively thin, so the primer head and the surface coating head of the primary coater are arranged in two series. In addition, the main factors affecting the surface quality of the coating are the viscosity of the coating, the proportion of diluent and the thickness of wet film. For the coating machine, the wet film thickness of the coating can be controlled by adjusting the gap pressure between the rollers of the coating head and between the coating roller and the support roller.
