Problems solved by technology

[0004] Dacromet, also known as Dacromet rust, high-gram rust, zinc-chromium film, etc., refers to coating the metal substrate with a liquid treatment solution containing zinc flakes, aluminum flakes, chromic anhydride, ethylene glycol, etc. After baking, a layer of non-decorative coating film with excellent corrosion resistance is formed on the surface of the metal substrate. The disadvantage is that the surface hardness is insufficient
In addition, since chromium plays a key role in Dacromet coating metal anti-corrosion technology, its content in the slurry is more than 20-26 mg per liter. The curi
