"Dacromet" is the best technology to replace traditional electro-galvanizing and hot-dip galvanizing, which pollute the environment seriously. It can not only process steel, iron, aluminum and its alloys, cast iron parts, structural parts, but also sintered metals, as well as special surface treatments. Widely used in automobiles, motorcycles, transportation facilities industries (metal parts for high-speed railways, subways, electrified railways, tunnels, bridge viaducts, highways), electrical appliances, ships, aerospace, marine engineering, hardware tools, electricity, Communications, petrochemicals, gas engineering, construction, military products, household appliances and other industries. It not only improves product quality but also protects the natural ecological environment, and is well received by the engineering community and environmental protection departments.
Dacromet process flow
Degreasing with neutral cleaning agent → surface oxide layer treatment by shot blasting machine → infiltration in multi-component alloy infiltration furnace → cooling → Shot blasting → passivation → dipping or spraying Dacromet solution → sintering, solidification and oxidation reduction at a temperature of about 300°C → cooling.
Application of Dacromet coating
1. Automobile and motorcycle parts
Since this product is a high-speed running vehicle, its parts require good stability , heat-proof, moisture-proof and corrosion-proof performance. In the past, many parts of Chinese automobiles had to be imported from abroad. Nowadays, many parts of Shanghai Volkswagen, FAW-Volkswagen, Wuhan Shenlong, Shanghai General, Guangzhou Honda and other automobile companies are processed by Dacromet coating.
2. Metal parts for subway tunnels, light rails, railways and electrified railways
Subways and tunnels are underground, with dark and humid environments and poor ventilation. Tracks, screws, bolts, Embedded parts and light rail contact mesh parts are very easy to rust. Now these parts are treated with Dacromet technology.
3. Metal parts for bridges, highways, and port machinery
A bridge, a viaduct, a high-speed railway, and a highway are all permanent buildings. A century-old plan, quality first . However, the corrugated guardrails of highways, metal components and fasteners of viaducts and bridges, due to being exposed to the sun and rain outdoors for a long time, will soon rust. Not only do they need to be painted every two or three years, but they also reduce the cost. safety factor. If key structural parts and fasteners are coated with Dacromet technology, they will not only be safe and reliable, but also beautiful and durable. .
4. Metal parts and structural parts for power transmission and distribution
Stamping parts and fasteners for electrical casings, high-voltage power transmission and distribution, urban power supply, line towers, poles, If metal parts, transformer covers, high-voltage switch cabinets and connection systems are all treated with Dacromet coating, although the one-time investment will be larger, they will be beautiful and durable, saving a lot of long-term maintenance costs
5. Hardware tools
6. Agricultural factory greenhouse roof truss structure
7. Solar water heaters, satellite antennas, and metal parts such as gas and liquefied gas.
In addition to the industries listed above, municipal engineering, machinery and electrical, railway terminals, shipbuilding and ship repair, construction and decoration, aerospace, marine engineering, geological drilling, petrochemical industry, gas engineering, agricultural science and technology, Bioengineering, military engineering, medical equipment, communication facilities, etc. can all develop and utilize Dacromet coating technology
