"Brass discoloration agent has strong anti-oxidation ability" in detail

Brass discoloration agent has strong anti-oxidation abilityBasic introduction Copper is a metal with porous structure and high surface activity. The corrosive medium and pollutants in the environment will be adsorbed into the die hole, and the pigment problem of the colored film will easily flow out, thereby reducing the corrosion resistance and other characteristics of the oxide film. Yubos anti-discoloration agent can make copper parts from active state to chemically passive state to achieve the purpose of anti-discoloration. Brass discoloration agent has strong anti-oxidation abilityCharacteristics Yuboshi copper discoloration inhibitor T401 can prevent the erosion of corrosive media, improve the corrosion resistance of the oxide film, enhance the anti-pollution ability, and maintain a good appearance of copper parts during use. Improve the stability, durability and light fastness of copper parts. Avoid electrical insulation and other properties. Brass discoloration agent has strong anti-oxidation abilityTechnical parameters The copper discoloration inhibitor introduced by Yubos at room temperature has the advantages of reducing energy consumption, improving working environment and improving production efficiency. With the continuous optimization of technology, the application scope is constantly expanding. Brass discoloration agent has strong oxidation resistanceInstructions for use The method of preventing discoloration of copper material: 1. Use at room temperature and passivate for more than 2 minutes. The longer the passivation time, the better the passivation effect.
2. After degreasing or polishing, the workpiece should be washed with running water for many times, and other dirt should be avoided into the passivation pool as much as possible. Since most of the polishing liquids contain acidic components, the workpiece after polishing must be fully rinsed, otherwise, once the acid is brought into the passivation liquid, the passivation film will be dissolved, and the passivation protection will not be achieved. Therefore, if necessary, the polished workpiece can be neutralized with 0.2~0.5% Na2CO3 solution before passivation.
3. This product is used at room temperature, and the treatment time is more than 2 minutes. Properly extend the treatment time (such as 15 minutes), so that the passivation effect will be reduced.
4. After the above treatment, rinse the workpiece with running water for 1~2 times, then rinse with pure water, spin dry the water droplets, and dry it at a temperature lower than 100℃.
When the copper parts are soaked in the anti-discoloration agent, the protective film is quickly formed on the surface. This transparent film does not affect the decorative effect of the copper parts, and can obtain a protective film of qualified quality without leaving marks. Because the protective film is fixed and dense on the surface, it prevents the discoloration of copper caused by contamination and corrosion conditions. Brass discoloration agent has strong anti-oxidation ability Purchase instructions Features Advantages:
1. Comply with RoHS environmental protection requirements, do not contain heavy metals, easy to biodegrade and help reduce environmental pollution;
2. This product has stable performance and can be used repeatedly;
3. The passivation film is dense and has strong corrosion resistance. Pure copper can pass the test of neutral salt spray>72 hours;
4. The treated product can be kept for more than 2 years without discoloration.
5. It will not affect the electrical conductivity, thermal conductivity, solderability and other properties of copper parts after use.
The resulting film is composed of natural and harmless organic compounds, which are easy to form a dense protective mechanism on the surface of copper parts, and this mechanism can have good adhesion with copper parts. It can effectively prevent oxygen from contacting with metal, so as to achieve the purpose of corrosion resistance.
