The method of surface processing of stainless steel nano copper plate!
At present, stainless steel nano copper plate is a popular decorative material, which is mainly derived from the old and retro processing of stainless steel through special processing technology. Stainless steel nano copper plate can bring a retro, heavy and simple atmosphere, which is very upscale and rich in culture. Therefore, it is widely used in copper doors, copper decorations, copper sculptures, vintage furniture copper accessories, study four treasures, antique and copper handicrafts, incense burners, copper handles, relief sculptures, display cabinets, curtain walls, sculptures and other fields, which are well received and loved by customers .
The use of stainless steel nano-copper plates has many advantages: the production and processing costs of stainless steel nano-copper plates are much lower than copper, so the processed products have greater price competitiveness, and the same can be obtained at a lower cost. Effect; due to the low hardness of copper, it is difficult to use in a large area, the hardness of stainless steel nano copper plate is higher; the chemical properties of copper are much more active than stainless steel. Stainless steel bronze is much better than copper in terms of corrosion resistance, wear resistance, water resistance and rust resistance, and has a longer service life.
There are generally two methods of copper plating on stainless steel: one is vacuum plating, and then plating is a method that uses electrolysis to attach a metal film to the surface of a metal or other material. It can act to prevent corrosion, improve wear resistance, electrical conductivity, light reflection and enhance aesthetics.
The second is water electroplating, which is the most commonly used stainless steel water electroplating: it does not rely on the external power supply in the aqueous solution, but on the reducing agent in the electroplating solution. A chemical reduction reaction takes place, whereby metal ions are continuously reduced on the autocatalytic surface. A process method for forming a metal coating. The first step in the treatment process is to dewax and degreasing the electroplated workpiece. After activation, alkaline copper is first electroplated. Plating time is about 10 minutes. After draining from the tank, it is cleaned, neutralized and activated before bright copper plating. Plating time is more than 20 minutes. When the coating is thick enough, take it out of the water tank for washing, activation, direct nickel plating and black plating. The plating time should be blackened evenly on the surface of the workpiece, then washed with water, dried and waited for treatment. Electroplated workpieces with bright copper can also become black after cleaning. Typically, they are dipped in a 5% potassium sulfide aqueous solution and turned repeatedly. When the surface of the workpiece is black or brown, take out the workpiece, wash with water, dry, and then wait for processing. Then, the workpiece that has been plated with black nickel, gun-colored or blackened is polished with a nylon wheel, and the degree of polishing is determined according to the requirements of the patina. When the workpiece achieves the desired effect, it can be sprayed with electroplating varnish, which is the anti-fingerprint treatment commonly used now, and then it is OK to dry and pack.
Stainless steel copper plating color: bronze, bronze, red copper, brass, blackened bronze, copper plating material: iron, aluminum, stainless steel
The difference in surface treatment process and method, the effect produced by each manufacturer is very different, in short, if you want to find the imitation copper sheet that suits you, the comparison of process and material is the most important.
