铝卷生产厂家:防锈铝板电镀前的处理

来源:不限ip注册送35体验金  发布时间:2020-10-09 16:04:27  

防锈铝板进行电镀时,因为受到铝的特殊性能的影响,需要有特殊的前处理,而这些前处理因不同防锈铝板和不同制件状况而需要有所调整,不能简单沿用通用工艺.因而,对于从事防锈铝板上电镀的工作者,有时需要做防锈铝板电镀前处理的实验.
Due to the special properties of aluminum, special pretreatment is needed when the antirust aluminum plate is electroplated. However, the pretreatment needs to be adjusted due to different antirust aluminum plates and different parts conditions, so the general process can not be used simply. Therefore, for the workers engaged in electroplating on antirust aluminum plate, sometimes it is necessary to do the pre-treatment experiment of antirust aluminum plate

进行防锈铝板电镀前的处理方案的实验,也是系统化的比照实验,需要对样件进行不同选定前处理工艺的处理,然后进行相同的电镀加工,再检测其结合力.这种比照实验的要点是要保证除了差别工艺点外,其他流程都是同一条件的,否则就没有了可比性而无法做出评价.

 


It is also a systematic comparison experiment to carry out the treatment scheme experiment of antirust aluminum plate before electroplating. Different pretreatment processes are selected for the sample, and then the same electroplating process is carried out. The key point of this comparison experiment is to ensure that except for the difference process points, other processes are under the same conditions, otherwise there is no comparability and evaluation can not be made
前处理工艺的选型和改进的办法的设计.铝圆片电镀前处理包括除油、酸蚀、化学镀或置换镀、预镀等四个重要工序.其中较为关键是化学镀或置换镀,因而,常常要做的实验都集中在这道工序上.当然不同的铝材和不同的加工办法对前处理有不同的要求,比方压铸铝件与轧制铝件的前处理就有很大区别,而即使是同一种加工方法,不同的铝材也有不同的前处理工艺,比方铝的含铜量的多少就直接影响其镀层的结合力.
The pretreatment of aluminum wafer electroplating includes four important processes: degreasing, acid etching, electroless plating or displacement plating, and pre plating. Among them, electroless plating or displacement plating is the most important process. Therefore, the experiments often need to be done are concentrated on this process. Of course, different aluminum materials and different processing methods have different requirements for pretreatment, For example, the pre-treatment of die-casting aluminum parts and rolling aluminum parts is very different. Even if the same processing method is used, different aluminum materials also have different pretreatment processes. For example, the copper content of aluminum directly affects the adhesion of the coating
