Henan Dacromet Coating Manufacturer

The Dacromet coating manufacturer in Henan found that the current Dacromet surface treatment ICBC needs to improve:
1. The sintering temperature of dacromet is high, the time is long, and the energy consumption is large. This requires us to control the temperature well when performing dacromet treatment. Too high temperature is not beneficial to surface treatment.
2. The conductivity of Dacromet coating is not good, so it is not suitable for parts with conductive connections, such as grounding bolts of electrical appliances. Due to the problem of conductivity, we will not use this treatment in some anti-corrosion work Way.
3. Dacromet contains chromium ions that are harmful to the environment and human body, especially hexavalent chromium ions, which have a carcinogenic effect. No matter what chemical additives or anti-corrosion solutions are, they are more or less harmful, and it is best to use them in moderation. important.
4. The surface color of Dacromet coating is single, only silver-white and silver-gray, which is not suitable for the individual needs of automobile development. However, different colors can be obtained through post-treatment or composite coating to improve the quality of truck parts Decorative and matching.
5. The surface hardness of Dacromet is not high, the wear resistance is not good, and the products coated with Dacromet are not suitable for contact and connection with copper, magnesium, nickel and stainless steel parts, because they will cause contact corrosion, Affect the surface quality and anti-corrosion performance of products.
The above content is the introduction of Dacromet Coating Manufacturer in Henan Province, and I hope it will be helpful to you.
