Semi-light nickel
1. Can get white color, uniform and smooth coating surface.
2. It can be used as a base nickel coating for pearl nickel, or directly as a nickel-plated surface with matte requirements.
3. Less organic decomposition products, bath liquid is not easy to aging.
4. Excellent dispersion ability, suitable for high decorative matte nickel plating requirements.
DN-1001 Semi-bright Nickel Plating Process
1. The coating has excellent ductility and leveling force, good columnar structure, and is suitable for various multi-layer Ni-Cr coating systems with extremely high corrosion resistance requirements.
2. The continuous operation of the process is good. If it can be combined with regular activated carbon adsorption, there is no need for large-scale treatment under normal circumstances.
3. Additives and solutions are fully compatible with the company's bright nickel system, and there is no need to wash in the subsequent bright nickel process.
DN-95 Semi-bright Nickel Additive
1. Suitable as a semi-bright nickel underlayer in multilayer nickel systems.
2. Does not contain coumarin, formaldehyde, high bath stability.
3. The coating has good filling and flexibility, and the potential difference between the semi-light nickel layer and the bright layer can reach 125-150 mV, which ensures that the double-layer nickel layer has excellent corrosion resistance.
DN-2500 High Sulfur Nickel Additive
1. As a layer of shock nickel plating between bright nickel and semi-light nickel
2. The sulfur content of the coating can reach 0.1-0.3, and the potential difference between the coating and the semi-bright nickel is 160-180 mV.
Its chemical and electrochemical stability is good, can use air stirring, less additive consumption.
DN-2001 High corrosion resistance nanocomposite nickel plating additive
1. Provide composite particles with nano-scale additives, which have excellent dispersion properties.
2. Very thin composite nickel plating layer can give the workpiece excellent corrosion resistance.
3. Simple operation, easy management, no special equipment, suitable for automatic line or manual line electroplating production.
DN-1003 Nickel Seal Plating Process
1. This process can significantly improve the corrosion resistance of nickel-chromium coatings.
2. In the electroplating process, a large number of particles are deposited in the plating layer, so that the subsequent chromium plating layer forms a corresponding number of micropores on the particle surface.
3. This process is easy to operate and control, and is used after semi-light nickel and light nickel.
4. Can meet the requirements of high corrosion resistance, especially suitable for outdoor supplies.
DZ-300 Nickel Seal Plating Process
1. This process is applied to multi-layer nickel electroplating process with high requirements for anti-corrosion performance.
2. This process contains a certain amount of non-conductive particles. A thin (1.0-3.0 microns) nickel seal is plated on the bright nickel coating, and then chromium is plated to form microporous chromium, which greatly improves the anti-corrosion ability.
3. In order to ensure the corrosion protection ability of microporous chromium, the thickness of bright chromium coating should be kept below 0.5 microns ｡
4. In order to ensure the corrosion resistance of the coating, each coefficient must be continuously monitored, and suitable methods must be used, such as copper plating method to test the number of micropores and measure the potential difference between bright nickel and nickel seal ｡
5. According to the standard, the number of micropores must be kept between 10,000 and 40,000 particles/cm2 (copper plating method). The potential value of this art should be about 20-40 mV positive than bright nickel. The determination of the number of microholes shall be specified at a certain position on the workpiece ｡
