Dacromet manufacturers in Henan mainly use the Dacromet process to treat the surface of parts. As a new treatment process, the Dacromet process has advantages and disadvantages compared with other treatment processes. Users can, according to their needs, Determine whether it is suitable to apply the Dacromet process. But what are the advantages and disadvantages of the Dacromet process? This question will be explained by the Henan Dacromet manufacturer.
Dacromet processing is a surface treatment technology. Compared with the traditional electroplating process, Dacromet has the advantage that the thickness of the Dacromet film layer is only 4-8μm, but its anti-rust effect is better than that of traditional electrogalvanizing, hot-dip galvanizing, etc. It is more than 7-10 times that of galvanizing or paint coating. The standard parts treated by Dacromet process, the pipe joints have passed the salt spray test for more than 1200h without red rust. The treatment process of Dacromet determines the quality of Dacromet There is no hydrogen embrittlement phenomenon, so Dacromet is very suitable for the coating of stressed parts. Dacromet can resist high temperature corrosion, and the heat resistance temperature can reach more than 300 degrees Celsius. The traditional galvanizing process has already started when the temperature reaches 100 degrees Celsius. The skin is scrapped. The Dacromet coating has good bonding force with the metal substrate, and has strong adhesion with other additional coatings. The treated parts are easy to spray and color, and the bonding force with the organic coating even exceeds that of phosphating. Membrane. Dacromet reduces the processing cost in the whole process of production, processing and workpiece coating.
Of course, the Dacromet process also has corresponding disadvantages. For example, some Dacromets contain chromium ions that are harmful to the environment and the human body, especially the hexavalent chromium ions have carcinogenic effects. (Under the environmental protection policy, Dacromet no longer contains Hexavalent chromium ions); the sintering temperature of Dacromet is high, the time is long, and the energy consumption is large. The surface hardness of Dacromet is not high, the wear resistance is not good, and the products coated with Dacromet are not suitable for copper , magnesium, nickel and stainless steel parts contact and connection, because they will produce contact corrosion, affecting the surface quality and anti-corrosion performance of the product. The surface color of Dacromet coating is single, only silver white and silver gray, which is not suitable for automobile development Personalized needs. However, different colors can be obtained through post-treatment or composite coating to improve the decoration and matching of truck parts.
The advantages and disadvantages of the Dacromet process are introduced here. I hope that after mastering this information, you can analyze your own needs and judge whether it is suitable to apply the Dacromet process. Of course, if you are sure to use Dacromet Craftsmanship, welcome to contact with Dacromet manufacturers in Henan, our factory has rich experience in Dacromet crafts.
