antique copper plate
Antique copper plate, also known as antique copper stainless steel plate, is made of bronze on the base material of stainless steel plate through complex surface treatment technology. The main process is divided into four categories: 1. Copper plating; 2. Vacuum titanium plating; 3. Water plating; 4. Paint. The main colors are: Antique Bronze, Antique Red Antique, Antique Brass Antique and Antique Black Antique. It combines the characteristics of waterproof, moisture-proof, wear-resistant and corrosion-resistant, high strength and easy processing of stainless steel plates, and is widely used in modern decoration projects.

Chinese name: antique copper plate
Color: bronze, red copper, brass, black copper

According to the classification of surface treatment technology: brushed antique copper plate, mirror antique copper plate, antique copper embossed plate, antique copper etched plate.

Stainless steel copper plating generally has four processes:

The first type: vacuum electroplating, then electroplating is the process of attaching a layer of metal film to the surface of metal or other material parts by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, reflective properties and enhance aesthetics.

The second type: water plating, which is the most used, stainless steel water plating: in the aqueous solution, it does not rely on external power supply, and only relies on the reducing agent in the plating solution to carry out chemical reduction reaction, so that the metal ions are continuously reduced on the self-catalyzed surface. A process for forming a metal coating. Its processing flow firstly removes wax and oil from the workpiece to be plated. After activation, it first electroplates alkali copper. The electroplating time is about 10 minutes. The electroplating time is more than 20 minutes. When the coating is thick enough, it is washed out of the tank, activated, and directly electroplated with nickel and black. The electroplating time is preferably black on the surface of the workpiece, then washed with water, dried, and ready to be processed. The copper bright electroplated workpiece can also be washed and blackened. Generally, 5% potassium sulfide aqueous solution is used for soaking, and it is turned over and over again. processing. Then, the black nickel-plated and gun-colored or blackened workpiece is polished with a nylon wheel, and the degree of polishing is controlled according to its requirements for patina. When the workpiece reaches the desired effect, it is sprayed with electroplating varnish, which is what we say The anti-fingerprint treatment and then dry the packaging is fine +.

Type 3: copper plating. Electroless copper plating is usually also called copper sinking or porosity, which is an autocatalytic redox reaction. First, it is treated with an activator to make a layer of active particles adsorb on the surface of the insulating substrate. Usually, metal palladium particles are used (palladium is a very expensive metal, and the price is high and has been rising. In order to reduce the cost, there are practical colloidal copper particles abroad. The process is running), copper ions are first reduced on these active metal palladium particles, and these reduced metal copper crystal nuclei themselves become the catalytic layer of copper ions, so that the reduction reaction of copper continues on these new copper crystal nuclei Superficially. Electroless copper plating has been widely used in our PCB manufacturing industry, most of which use electroless copper plating for PCB hole metallization. Copper-plated stainless steel is the most expensive of all copper imitation forms.

The fourth type: paint, we spray paint on the surface of the stainless steel plate, and then make it old through brushing, polishing and potion, and we can also make antique copper stainless steel plate. The price of this process is relatively cheap, and the disadvantage is that the color fixing effect is relatively poor compared with the above three processes, and the color is relatively dull.
