How to choose the plating plate to select the plating layer from dark to black. Completely lost the original appearance. For the image of the company and the pavement, the plaque made of copper plate can be wiped every day or every other day, and it is easy to clean the bridge. This can be avoided by selecting the coating or making the necessary surface treatment during manufacture.

Simultaneously. Selecting a reasonable coating and then protecting it with an organic clear coating can also achieve the purpose of delay retention and decoration.

2. Protective decorative coating This coating not only prevents the surface of the sign panel from being corroded. Moreover, it can impart a certain long-lasting gloss appearance to the surface. With the development of China's economic construction / this coating is developing rapidly, and the amount is large. Most of the protective decorative coatings are multi-layered. That is, the underlayer is first plated on the substrate. The surface is then plated (and quite a middle layer) because it is difficult to find a single coating that has such a perfect function. Some coatings have good protection. However, the decoration and brightness are poor. Other coatings are decorative. However, the protection ability is poor. So people are in the long-term life and production practice. Use their respective characteristics to make a reasonable mix of coatings. A coating that is both corrosion resistant and aesthetically pleasing. Such as our common car. Bicycle parts and the like can be used for a long time in the atmosphere and have certain decorative properties. This method is also used in all kinds of signage and panel manufacturing of automobiles, and the other is to match the private body. Second, it has the duality of anti-corrosion and decoration. same.

Signage for the mining machinery and the signs of weapons and equipment are of this type. As early as the 1960s and 1970s, the coating used in this area used copper and cadmium alloy as the bottom layer. Although it is more protective. However, it is easy to oxidize and discolor. If it is coated with a layer of bright chrome, it will have a certain brightness. And wearable. With the development of electroplating technology, copper-nickel-chromium multi-layer plating is used at home and abroad, which is more protective than the former. Wear resistance. Decorative. The durability has been greatly improved. This process is now used in weathervanes, signage and export or high-end large equipment signage for premium cars. Moreover, the surface of the signboard with higher surface requirements is decorated with a precious metal plated "é“‘", which has been seen on the market.

The use of stainless steel as a substrate for the manufacture of signage panels is now very popular. But the material and model (how much other metal content) make the manufacturer hurt. The reason is that the placards produced sometimes produce rust under good conditions. In this case, surface selective plating is required to make up for it.

Here is a brush plating technique.

Brush plating is also known as slotless plating. It got out of the aqueduct. It is a technique for repairing plating. It is very suitable to apply it in sign making. For example, signage panels for ships are typical for use in harsh climates. It should be noted that the exposed surface of the ship and the top of the top cannot be made of aluminum plate, otherwise chlorine or hydrogen chloride in the ocean water vapor will quickly erode it. The surface of the signage panel that is installed or used for a period of time will be dark. At this time, the same plating layer can be directly plated without taking off, and satisfactory results are obtained.

3. Other coatings can be selected for wear resistance according to different environments.

High temperature resistance. Conductive coatings are not listed here.

If it is in a harsh environment such as acid-base steam for a long time. Such as electroplating workshop, etching workshop. Instead of using signage panels made of metal substrates, application engineering materials (color) directly engrave graphics and text. The embossed pattern can also be etched by organic etching. Note that the recessed pattern does not require ink and coating because even the coating fastness is extremely poor. At this time, a double-layer two-color material plate should be used, and the bottom plate should be exposed after engraving or etching. A contrasting color contrast with the surface sheet.
