Dacromet surface treatment is a very commonly used metal anti-corrosion coating technology. Below we invite Henan Dacromet surface treatment manufacturers to introduce the advantages of this metal surface treatment coating technology:
1. Dacromet is the transliteration and abbreviation of DACROMET, abbreviated as Dacromet, Dacromet rust, and Dickron. It is named zinc-chromium coating in China. It is a kind of zinc powder, aluminum powder, chromic acid and deionized water. The new type of anti-corrosion coating is an effective metal anti-corrosion method, which is mainly used for metal structure facilities in various industries.
2. Compared with the hot-dip galvanized coating technology, the hot-dip galvanized coating is thicker, the appearance is rougher, the aesthetics is poor, and the surface treatment can resist high temperature; the Dacromet coating is thin, the appearance is bright, and the coating adhesion is strong. Better, no hydrogen embrittlement, good corrosion resistance.
3. In terms of salt spray time, the salt spray test time of Dacromet is relatively long, but the test is that the corrosion resistance of hot-dip galvanizing is better in a neutral environment.
4. Henan Dacromet surface treatment process: organic solvent degreasing, mechanical polishing, spraying, baking, 2 times spraying, baking, drying.
