Posted on 2015-12-21 Dacromet means non electrolytic zinc flake coating, coating the whole process without waste water, waste emissions, is the best substitute technology for serious pollution of the traditional hot dip galvanized zinc.
Dacromet has a wide range of applications, it can not only deal with steel, iron, aluminum and its alloys, but also can handle sintered metal, and the special surface treatment. It relates to the industry, the industry is also very much, such as:
1.automobile and motorcycle industry
The origin of Dacromet technology in the automotive industry, the world famous automobile companies, such as American general motors, Ford, Chrysler, France's Renault, Germany's Volkswagen, Italy Fiat and Japan's TOYOTA, MITSUBISHI and other auto parts in surface treatment are required to make use of Dacromet technology. Auto parts after Dacromet has high stability, heat insulation, moisture-proof and anti corrosion. With China's accession to the WTO industry, the pace with international standards and China's automobile more and more quickly, application of Dacromet technology in domestic automobile industry more wide.
2.electrical communication industry
Home appliances, electronic products, communications equipment and other high-end products, the original components, accessories, etc., and some need to be placed outdoors, so the quality of the product is higher, in the past the use of electric galvanized method, quality is low and can not meet the requirements. If the use of Dacromet technology, anti-corrosion performance products will greatly enhance the service life of the product, the quality will be greatly improved, and beautify the environment, expand the market. So more and more enterprises begin to use this technology in China. Such as Guangzhou "beauty", "air conditioning Himin Solar water heater, communication tower, ZTE outdoor machine cabinet, etc..
3.transportation facilities industry
The subway and tunnel in underground environment, damp, poor ventilation; bridge, the viaduct and port machinery are all outdoors under the sun and rain, they were prone to rust and corrosion phenomenon will happen soon, greatly reduce the safety factor. If the key pieces of the structure and fasteners with Dacromet technology, not only safe and reliable, durable and beautiful. Now the domestic subway engineering, port machinery have begun to use the dacromet coating processing.
4.transmission and distribution power supply
High voltage power transmission and distribution, in addition to city power supply, power supply cable, open wire are naked outdoor overhead, not only the sun and rain, but also affected by environmental pollution, the maintenance task is very heavy. The tower and pole high voltage transmission line of the cross arm, a supporting iron clamp, elbow, bolt, steel cap, transformer oil tank and the fasteners are used if Dacromet technology, although a large one-time investment cost rises, but beautiful and durable, once and for all, saving large amount of annual maintenance costs. The high voltage switch industry, such as the West high, flat opening has taken the lead in quoting the technology and achieved remarkable results. In addition to the above example several industries, municipal engineering, machinery industry, railway terminals, ship building, aerospace, marine engineering, hardware tools, outdoor metal component in the study of application of Dacromet technology.
Dacromet coating limitDacromet coating has many advantages, but it also has some shortcomings, mainly reflected:
1.conductive properties of Dacromet coating is not very good, so it should not be used for conductive connection parts, such as electrical grounding bolts etc..
2.because of Dacromet coating is a high temperature sintering layer, so its surface hardness and scratch resistance than other traditional methods slightly worse, special occasions the need for postprocessing.
