Xinxiang Dacromet surface treatment technology is a new type of surface treatment technology. Compared with the traditional electroplating process, the Dacromet process is a kind of “green plating”.

Advantages of Dacromet surface treatment technology:

1. Super corrosion resistance: The anti-rust effect of Dacromet film is 7-10 times higher than traditional electroplating zinc, hot-dip galvanizing or coating coating method. Standard parts and pipe joints processed by Dacromet process No red rust appeared in the salt spray test for 240-1200h or more;

2, no hydrogen embrittlement: Because Dacromet technology does not carry out any acid treatment during the treatment, there is no hydrogen permeation problem during electroplating, and the layer is cured at high temperature, so Dacromet is guaranteed from the process. The layer is not paste present in hydrogen embrittlement;

3, high and low temperature impact resistance: Dacromet can withstand high temperature corrosion, heat resistant temperature up to 300 ° C or more, the traditional galvanizing process, the temperature has reached 100 ° C when the skin has been scrapped;

4. Good adhesion and recoating performance: Dacromet coating has good adhesion to metal matrix, and has strong adhesion to other additional coatings. The treated parts are easy to be sprayed and colored, combined with organic coating. The force even exceeds the phosphate film;

5. No pollution and pollution: As a “green plating” process, the Dacromet process adopts a closed-circuit cycle, so there is almost no pollution hazard;

6. Good permeability: Due to the electrostatic shielding effect, it is difficult to plate zinc on the deep holes, slits, and key inner walls of the workpiece. Therefore, the above parts of the workpiece cannot be protected by electroplating.

7. Spot welding performance: After the Dacromet coating of the angled parts, spot welding shows that the Dacromet layer has good electric welding performance. From the Dacromet process, the protective performance of Dacromet after the county electric welding is better than that of the first Dakoro after spot welding;

8. Preventing electrochemical corrosion of aluminum: The anti-corrosion of Dacromet coating is based on the passivation of chromic acid and the controlled sacrificial protection of zinc, thus inhibiting the consumption of zinc and improving corrosion resistance. performance;

9. High weather resistance: Dacromet can withstand sulfur dioxide, soot, acid rain and dust erosion at a certain layer thickness.

The above is the introduction of Xinxiang Dacromet manufacturers for everyone, want to know more detailed consultation, welcome to lock our official website, we will continue to update in the later period.
