Cyanide free alkaline bright copper
Complete pre plating and thickening on copper alloy in one step, with a coating thickness of up to 10 μ Above m, the brightness is as bright as an acidic bright copper coating. If blackened, it can achieve a pitch black effect and has been operating normally for two years in a 10000 liter tank.
It can completely replace the traditional cyanide copper plating process and bright copper plating process, and is suitable for any metal substrate: pure copper, copper alloy, iron, stainless steel, zinc alloy die castings, aluminum, aluminum alloy workpieces, and other substrates. It can be hung or rolled plating.
Cyanide free bright silver plating
The ordinary type uses thiosulfate as the main complexing agent, while the advanced type uses sulfur-free organic compounds as the main complexing agent. Full bright coating thickness up to 40 μ Above m, coating surface resistance~41 μ Ω· cm, hardness~HV101.4, thermal shock 298K (25 ℃) qualified, very close to the performance of cyanide silver plating.
Cyanide free gold plating
The main salt of cyanide free autocatalysis electroless gold plating is Na3 [Au (SO3) 2], and the gold layer thickness can reach 1.5 μ m. It has been used for gold plating on high-density flexible circuit boards and electronic ceramics.
Non formaldehyde copper plating
Non formaldehyde autocatalysis electroless copper plating is used for through hole plating of circuit boards and metallization of nonconductive surfaces. Replacing toxic formaldehyde with cheap and non-toxic phosphates, there is no commercial product available domestically or internationally. Laboratory research has been basically completed, with a deposition rate of 3-4 μ M/h, with a lifespan of over 10 cycles (MTO), and a dense and bright coating. But further improvement and pilot testing are needed.
Pure palladium electroplating
Ni can cause dermatitis, and the European Union has long refused to import jewelry containing Ni. Palladium is the best substitute for Ni metal. This project was completed in 1997 and includes two processes:
One is thin palladium electroplating, with a thickness of 0.1~0.2 μ m. It has been used as a anti-corrosion decorative coating and a silver discoloration resistant layer on white copper and tin;
The second is thick palladium electroplating, with a thickness of up to 3 μ M has no cracks (international level) and has not yet entered the domestic market due to the high cost of palladium.
Blue white and color passivation agents for trivalent chromium zinc coatings
Replace carcinogenic hexavalent chromium salts with trivalent chromium salts. The blue and white passivation has a color similar to that of a chromium plating layer. It has undergone neutral salt spray testing for more than 24 hours, and some special treatments can achieve neutral salt spray testing for more than 96 hours. It has gone through ten years of market testing. Compared to blue white passivation, color passivation has a bright color, and the salt spray test time is much longer, reaching 48 to 120 hours.
Pure gold electroplating
The main salt is K [Au (CN) 2], which belongs to the micro cyanide process. Plating gold purity 99.99%, gold wire (30 μ m) Bond strength>5g, solder ball (25 μ m) Shear strength>1.2Kg. The Knoop hardness H<90 has been used for gold plating on high-density flexible circuit boards.
Plating of white steel
There are two types of Pd (60) Ni (40) and Pd (80) Ni (20), which have been used as substitute gold coatings and anti silver discoloration layers in electronic products.
Nano nickel
Environmentally friendly products developed using nanotechnology can completely replace traditional cyanide copper pre plating and traditional chemical nickel plating. They are suitable for iron parts, stainless steel, copper, copper alloys, aluminum, aluminum alloys, zinc, zinc alloys, titanium, etc., and can be hung or rolled plating.
High speed chrome plating
Cost saving, high plating speed, high wear resistance, and high corrosion resistance. Not only can it improve current efficiency, but it can also enhance wear and corrosion resistance. Suitable for any hard chromium plating treatment, including; Microcrack chromium, milky white chromium, can also be used for bright chromium, etc. Good quality, stable process, high production efficiency, energy conservation, and significant economic benefits.
