China is the world's largest producer and consumer of anodized aluminum is widely used in many fields. anodized aluminum is the main raw material for aluminum production. With the economic development, China's industrial structure is continuously optimized, and China's anodized aluminum production capacity continues. According to the “China's anodized aluminum industry production and sales demand and investment analysis report” released by the Prospective Industry Research Institute, the cumulative output of China's anodized aluminum in January-December 2016 reached 60.83 million tons, an increase of 7.94% over the same period of the previous year. Say. The development of the anodized aluminum industry is also a good opportunity.


 
The main plates of anodized aluminum plates are mainly 5 series, among which 5005 aluminum plates, 5052 aluminum plates, 5083 aluminum plates, 5086 aluminum plates, 5182 aluminum plates and 5251 aluminum plates are common. anodized aluminum plates are mainly used in rail transit, automobile vehicles, ship transportation, electronic appliances, construction. And engineering molds and other fields.
 
As the leader in the production of aluminum foil and foil in China, Henan Signi Aluminum has a rigorous workflow, excellent equipment and rich experience. The alumina board produced has its own performance advantages.
 
1, high hardness, good corrosion resistance
 
In the anodizing experiment, an aluminum plate is placed in a corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is performed under specific conditions and an applied current. The aluminum plate of the anode is oxidized, and a thin layer of alumina is formed on the surface, the thickness of which is 5-20 μm, and the hard anodized film can reach 60-200 μm. The product has the characteristics of high hardness, good insulation, strong corrosion resistance and strong adsorption capacity.
 
2, anti-pollution fire, high security
 
There is no fingerprint on the surface of the product, there will be no traces of stains, easy to clean, and no corrosion spots. No paint and any chemical substances on the surface, 600 ° high temperature does not burn, does not produce toxic gases, in line with national fire protection environmental requirements.
 
3, good weather resistance, suitable for processing
 
The standard thickness oxide film (3μm) of the anodised aluminum plate is used for a long period of time without discoloration, corrosion, oxidation, and rust. An anodized aluminium plate with a thick oxide film (10 μm) can be used outdoors, and can be discolored without being exposed to the sun for a long time. The product can be continuously processed at high speed, which is convenient for direct processing into products. It does not require complicated surface treatment, which greatly shortens the production cycle and reduces the production cost of the product.
 
With the development of China's economy, various industries such as electronics, machinery, automobiles and other industries have made rapid leap forward, the market demand for aluminum is also growing, and alumina production will continue to grow. The future of the alumina industry is very optimistic. Henan Signi will also improve itself and open up the market.
