With the advancement of human science and technology, more and more processes appear in people's production and life. When it comes to new processes, I have to mention the metal surface treatment-Dacromet surface coating. There may be many people who are interested in Dacromet I don't have a special understanding of Crowe technology, so I will explain it to you one by one below.
The performance characteristics of the coating after Dacromet treatment:
1. The unpassivated galvanized layer generally corrodes the iridescent passivation film with a thickness of 1um-3um 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 surface treatment, the moisture and heat resistance of the coating is also greatly improved;
3. At -45 degrees Celsius and 80 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 coating;
5. Crispness 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 the crispness of the workpiece.
After the above description, everyone has a certain understanding of the performance characteristics of Henan Dacromet treatment. In addition, Dacromet technology also has strong corrosion resistance characteristics. The workpiece after Dacromet treatment is naturally Correspondingly, its corrosion performance is improved.
