Dacromet, also known as zinc chromate film coating, it has high corrosion resistance, is currently in the germination stage, is a high-tech cleaner production technology, it is the epoch-making surface treatment industry a new leap forward.
This process can replace the galvanized steel parts, cadmium, zinc-based alloys, hot-dip galvanizing, thermal spraying of zinc and mechanical zinc plating, the main advantages are:
1, high anti-corrosion: resistant to smog 600-1200h, 7-10 times higher than electro-galvanized;
2, no hydrogen embrittlement: hydrogen embrittlement does not produce special preparation for high strength bolts and components of the surface anti-corrosion treatment;
3, high weatherability: adapt to all kinds of climate change and hot and cold changes, exposure parts and immersion components;
4, high heat resistance: heat temperature up to 300 ℃, suitable for automotive and motorcycle engine parts of high-strength components;
5, clean, no pickling, no harmful gases and liquid discharge, is a cleaner production process.
Dacromet coating has now been widely used in automobiles, motorcycles, building components, bridges, electricity, highway guardrails, railways, shipping and military industries.
