What are the advantages of Dacromet technology?

Super corrosion resistance: The anti-rust effect of dacromet film is 7- 10 higher than that of traditional zinc plating, hot-dip zinc plating or coating. Standard parts and pipe fittings treated by Dacromet process have no red rust after salt spray test for more than 240-1200 h.

2. No hydrogen embrittlement: Dacromet technology does not carry out any acid treatment in the treatment process, and there is no hydrogen permeation problem during electroplating. The coating is cured at high temperature, which technically ensures that Dacromet coating will not appear hydrogen embrittlement.

3. High and low temperature impact resistance: Dacromet is resistant to high temperature corrosion, and the heat resistance temperature can reach above 300℃. However, the traditional zinc plating process has been peeled and scrapped when the temperature reaches 100℃.

4. Good adhesion and recoating performance: Dacromet coating has good adhesion to metal matrix and strong adhesion to other additional coatings, and the treated parts are easy to be painted and colored, and the adhesion to organic coating even exceeds that of phosphating film.

5. Good permeability: Due to electrostatic shielding, deep holes, slits, inner walls of pipe fittings and other parts of the workpiece are difficult to be galvanized, so the above parts of the workpiece cannot be protected by electroplating.

6. Pollution-free, pollution-free: Dacromet process, as a "green electroplating" process, adopts closed cycle, and there is almost no pollution hazard.

7. Bonding force between coating and substrate, and bonding force between coating and paint film: In the humid and hot test environment, the bonding force between Dacromet coating and paint film reached the national first-class and second-class standards, and the bonding force between Dacromet coating and substrate was both first-class standards.

8. Spot welding performance: The spot welding of corner parts after Dacromet coating shows that Dacromet coating has good spot welding performance. From the Dacromet process, the protection of spot welding before Dacromet is better than that after Dacromet.

9. Preventing electrochemical corrosion of aluminum: The corrosion protection of dacromet coating is based on passivation of chromic acid and controllable sacrificial protection of zinc, thus inhibiting the consumption of zinc and improving the corrosion resistance.

10. High weatherability: Dacromet can withstand the corrosion of sulfur dioxide, acid rain and smoke under a certain coating thickness.

1 1. Low friction: after proper treatment, dacromet coating containing lubricant can produce an ultra-low friction coefficient of 0.06-0. 12, and a medium friction coefficient of 0. 12-0. 18 after general treatment.

12. Good matching accuracy: Generally, dacromet coating can be controlled between 6-8um, so the matching accuracy of dense solid can meet the accuracy requirement of 6g/6n.

Referring to the news content of Hejun official website industry, I feel that their understanding of Dacromet is quite profound. If you need knowledge, you can search Changzhou Hejun for more.
