Method for pre-plating on aluminum
ã€China Aluminum Network】Aluminum electroplating is subject to the special properties of aluminum and requires special pre-treatments. These pre-treatments need to be adjusted due to different aluminum materials and different parts, and cannot be simply followed by general-purpose processes. Therefore, for those who are engaged in plating on aluminum, it is sometimes necessary to perform a pre-plating test on aluminum. To carry out this test, the first is the selection of the pretreatment process and the design of the improved method. The pre-plating treatment on aluminum includes four important processes such as degreasing, acid etching, electroless or displacement plating, and pre-plating. The key is electroless plating or displacement plating. Therefore, the tests that are often done are concentrated on this process. Of course, different aluminum materials and different processing methods have different requirements for pretreatment. For example, the pretreatment of aluminum die casting parts and rolled aluminum parts is very different, and even if the same processing method, different aluminum materials are different. The pre-treatment process, such as the amount of copper in aluminum, directly affects the adhesion of the coating. The test of the pre-treatment scheme for plating on aluminum is also a systematic comparison test, requiring different selected pre-treatment processes on the sample, followed by the same electroplating process, and then testing its binding force. The point of this comparative test is to ensure that, except for differential process points, the other processes are all identical conditions, otherwise there is no comparability and no evaluation can be made. The light belt, which looks like an inconspicuous lighting product, can be used properly in the space to show the layering of the light and make the space environment more soft and emotional. Use "light" as an important element of "activating space" to make simple space no longer monotonous.

What is the way to perfectly integrate the invisible light into the space? Let's start with the three most common ways!
Ceiling design
The light belt is designed in the ceiling to increase the sense of hierarchy at the top, combine light and dark, and form one or more effects of virtual and real contrast and dynamic and static combination through color temperature adjustment.
Cabinet design
Integrating the light belt into the cabinet can visually expand the sense of space and weaken the sense of closure, and the soft light will not cause a sense of discord. In terms of practicality, it can be used as lighting in the cabinet to prevent the dark inside the cabinet from affecting the use.
Space decoration
In addition to the use of light strips in the ceiling of the living room and other large court exhibitions, we can also create different light shapes on the background walls of the living room and bedroom, stairs, corridors and other walls through the combination of light strips and space design, and the personality is fully reflected in the details.
