The As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise. Franc
China is the world's leading silicon metal origin, Chinese silicon metal production to 95-100 million tons in 2007, silicon metal consumption capacity of more than 250,000 tons, but in recent years, demand for silicon metal in China are also increasing, consumption the proportion in the total production is also rising. China's silicon metal production capacity is relatively large, the production is mainly concentrated in Guizhou, Yunnan, Fujian, Guangxi, Sichuan, Hunan. Metallurgical grade silicon metal 553 and 441 haave a wider distribution area, mainly in Guizhou, Hunan, Sichuan, Yunnan, Guangxi, Inner Mongolia, Xinjiang, Guizhou, which is the main producing provinces of silicon metal production to total output 15% -35%.In the next 5-10 years, silicon metal market demand will continue to steadily increase. With the popularity of cars in more and more places, the aluminum alloy industry will continue to increase the amount of silicon metal. In addition, the chemical industry will also become the main driving force of the increase in demand for silicon metal. In the next five years, world demand for silicon metal average annual growth rate will reach 5%. With the global economic integration and international division of labor in economic development, China is rich in silica, small hydropower resources and cheap labor, the prospects for the development of the silicon metal industry is good. The way out of the silicon metal production is the development of high value-added products. Silicon metal powder, high purity silicon metal products in the market, higher sales price, and the state to encourage the production of high value-added products will also be given to the export tax rebate, the Chinese silicon metal industry is a trend to the development of deep processing.According to the survey by metal powder supplier, China's production of silica powder capacity of about 250,000 tons, mainly ordinary silica powder, high purity and ultrafine silica powder rely heavily on imports. Preliminary forecast of the 2013 China's demand for ultra-fine silica powder will reach more than 100,000 tons. Among them, the rubber industry is the largest user, the coatings industry is important to have great potential applications, electronic molding compounds, silicon-based board materials and electrical and electronic castable to rely on imports of high purity and ultrafine silica powder raw materials, only the price of the ordinary spherical silica powder -3 yuan / ton, while the price of high purity and ultrafine silica powder is as high as several hundred thousand dollars / ton. Silicon metal powder production capacity not only failed to excess and still a gap. The report shows that although the Chinese silicon metal capacity expansion soon, but due to the reason of the construction period as well as market fluctuations, silicon industry there has been a shortage phenomenon. In 2008, silicon powder aspects of production of 4500 tons, silica fume demand has more than 20,000 tons, which means that about 3/4 of the demand we must rely on imports to meet. According to their estimates, in 2009 China's output of photovoltaic cells to maintain the 2008 level of 2,300 megawatts, 12 tons of silica fume industry average calculation in accordance with the per megawatt photovoltaic cells, also more than 28,000 tons of silica fume. It is estimated that the silica fume production in 2009 may exceed 10,000 tons, which means that at least need to import nearly 20,000 tons of silica fume, in order to meet the demand of domestic production. Silicon metal is an easy-brittle material, sieve residue can not be well controlled in the grinding process, over-grinding serious, resulting in silica fume waste, high production costs, product size is not standard, making the product not only yield not also not competitive.Source: http:// www.mhcmp.com Article Tags: Chinese Silicon Metal, Silicon Metal Production, Ultrafine Silica Powder, Chinese Silicon, Silicon Metal, Metal Production, Metal Powder, High Purity, Silica Powder, Ultrafine Silica, Silica Fume
