With the continuous advancement of science and technology, more and more new processes appear in people's production and life. There may be many people who don't know much about Dacromet technology. Let's talk about the coating after Dacromet treatment. performance characteristics.
1. The unpassivated galvanized layer generally corrodes the 1um-3um thick iridescent passivation film in 10 hours after the salt spray test, and it can be corroded in 200 hours. In the Dacromet salt spray test, it takes 100 hours Only 1um is corroded, and the corrosion resistance is 7 to 10 times higher than that of traditional surface treatment;
2. After Dacromet treatment, the moisture and heat resistance of the coating is also greatly improved;
3. At -45 degrees Celsius to 85 degrees Celsius, the samples are kept warm in the high and low temperature test chamber for 1 hour each, the conversion time is not more than 5 seconds, and the number of cycles is 3 times. There is no change in the two coatings;
4. The bonding force between the coating and the substrate, and the bonding force between the coating and the paint film;
5. Hydrogen embrittlement is a disadvantage that the traditional galvanizing process has not been able to completely overcome. This is because the general electroplating process will use pickling, electrolytic degreasing, electrodeposition and other processes, which will lead to hydrogen embrittlement of the workpiece. Due to the Dacromet technology There is no acid treatment during the treatment process, and there is no hydrogen permeation problem during electroplating, and the coating is cured at high temperature, so the process ensures that the Dacromet coating will not have hydrogen embrittlement;
After the above related descriptions, everyone must have a better understanding of the performance characteristics of the coating after Henan Dacromet treatment. In addition, Dacromet coating technology also has a certain corrosion resistance. After Dacromet The treated workpiece can naturally improve its corrosion resistance correspondingly. So the relevant introduction about the performance characteristics of the coating after Dacromet treatment is here. Our company also produces various Dacromet technologies that can The mechanical equipment used, such as: Dacromet automatic coating equipment, Dacromet coating solution mixing equipment, etc. If you are interested in Dacromet technology, you can call us for consultation.
