镀铝锌板是近年来我国因高端应用而产生的一种新型材料。它通常被称为CCLI。由铝锌镀层(55%铝、43%锌、1.6%硅)制成的产品,经表面脱脂、磷化、复合酸盐处理,涂有机涂层,烘烤而成,耐蚀性优于镀锌。

在各种铝锌镀层中,通过镀后热扩散处理,研制出合金铝锌镀层,其耐蚀性是普通热铝锌镀层的两倍以上,镀层表面的锌花可以通过合金处理消除;同时,减少了点焊过程中锌的蒸发,降低了锌蒸气对点焊机铜电极的污染程度,提高了电极的使用寿命。为了保证涂层的良好附着力,汽车外板厚涂层采用高效的加热和冷却措施(高效燃烧器或感应加热器),并配备各种合金传感器。通过仪器分析和计算机指令,及时调整相应的涂层结构,以满足高冲压变形的要求

In recent years, aluminized zinc plate is a new type of material produced due to high-end application in China. It is commonly referred to as CCLI. It is a product made of aluminum zinc plating plate (55% aluminum, 43% zinc and 1.6% silicon) with better corrosion resistance than zinc plating, which is treated by degreasing, phosphating and complex acid salt on the surface, coated with organic coating and baked.
In the variety of aluminum zinc plating, through the heat diffusion treatment after plating, the alloy aluminum zinc plating plate is developed, the corrosion resistance is more than twice that of the ordinary hot aluminum zinc plating plate, and the zinc bloom on the coating surface can be eliminated through the alloy treatment; at the same time, the evaporation of zinc during spot welding is reduced, the degree of zinc vapor pollution on the copper electrode of spot welding machine is reduced, and the service life of the electrode is improved. In order to ensure the good adhesion of the coating, the high-efficiency heating and cooling measures (high-efficiency burner or induction heater) are adopted for the thick coating of the outer plate of the automobile, and various types of alloying sensors are equipped. The corresponding structure of the coating is adjusted in time through instrument analysis and computer instructions to meet the requirements of high stamping deformation 。
