Production And Distribution Of Aluminum Powder

wallpapers Robot Tech 2021-01-28
Aluminum is a silver-white light metal. There is malleability. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air. Aluminum powder and aluminum foil can burn violently when heated in the air and emit a dazzling white flame.
 
Aluminum is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solutions, but hardly soluble in water. The relative density is 2.70. Melting point is 660°C. The boiling point is 2327°C. The content of aluminum in the crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the crust. The development of the three important industries of aviation, construction, and automobiles requires the characteristics of materials to have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. The application is extremely wide.
 
Yield
 
In 2007, China's express production of aluminum processed materials was 11.759 million tons, an increase of 44.3% compared with the 2006 express number of 8.148 million tons. The estimated profile is 6.6 million tons, an increase of 36.2% over 2006.
 
Distributed
 
From the perspective of the aluminum processing industry, the three regions of the Pearl River Delta, the Yangtze River Delta, and the Bohai Rim, with the central region represented by Henan developing rapidly. Since the beginning of the new century, the proportion of the total output of the top 10 provinces and regions in the country’s aluminum processing material output in the total output of the country has gradually increased. It was 82.1% in 2000, 84.7% in 2005, 87.1% in 2006, and 87.63% in 2007. . The output rankings of Guangdong and Henan continue to maintain the top two, and their proportions are still rising. The provinces with faster output growth are Shandong and Hunan. Shandong's ranking rose from sixth to third in 2006. The output was close to 1 million tons, reaching 994,800 tons, an increase of 85.6% over 2006. Hunan Province came in behind with a good result of 211,200 tons, squeezing out the top ten in Hebei Province, which has a relatively small increase in output.
 
The construction aluminum profile industry in Guangdong Province has a prominent position in the country and has an absolute advantage. Guangdong Province is a major province in the processing and manufacturing of aluminum profiles in China, as well as a major consumer of aluminum. At present, the aluminum processing capacity in Guangdong Province exceeds 3 million tons per year, and the comprehensive output value exceeds 100 billion yuan. An industry with obvious scale advantages and brand advantages has been formed. According to statistics from China Nonferrous Metals Industry Association, in 2006, there were more than 560 aluminum extrusion plants in China with production licenses, and more than 210 in Guangdong Province. Among the top 10 aluminum extrusion products in the country, Guangdong Province accounted for 6 companies, and Guangdong Province The province's aluminum profile production accounts for about 55% of the country, and its market share exceeds 45% of the country. There are 17 aluminum processing enterprises with Chinese famous brands in the country, and there are 10 units in Guangdong Province, of which 9 are aluminum profile factories and 1 is a plate, strip and foil manufacturer.
