Have been measured in the past is dissolved in the melt of the amount of hydrogen by vacuum test method, which is the process of injecting the sample melted aluminum steel cup and let it solidify in a vacuum chamber. Observe the solidification process found during solidification bubble level change indicates the amount of hydrogen present. Use a sample slice after solidification can check the size of the formation of bubbles. Unfortunately, these methods are not accurate, but also by the melt in the presence of hydrogen gas bubble nucleation of oxide particles greatly affected. Test dissolved hydrogen better approach is to use a liquid extraction technology specially designed display of hydrogen equipment. Renewable resources can save a lot of energy, water and production materials, lower production costs, reduce environmental pollution. At the same time, many non-renewable mineral resources have characteristics, which determine the value of renewable resources, recycling has inestimable. [1] First, industrial development potential. According to incomplete statistics, China's renewable resources, recycled nearly 100 million tons a year, worth more than 2,000 billion yuan, Zhejiang wire and cable recycling, in which more than 4,000 tons of scrap iron and steel, 30 million tons of waste paper, scrap metals more than 500 million tons , 6 million tons of waste plastics, waste tires more than 5000 million, the other 10 million tons of waste materials. In addition, in recent years, China's annual imports of all types of renewable resources are also more than 2,000 tons. If you include the mining industry since the resumption own waste, the value of China's annual recycling of renewable resources up to 40 billion yuan. Renewable resources is not absolute, is relative, Jiangsu wire and cable recycling, conditional existence, Hubei wire and cable recycling, humanity must be rational exploitation and protection. Otherwise, our children and grandchildren will be resource crisis and the energy crisis. Renewable resources in order to save resources and the rational development and utilization of limited resources, wire and cable recycling, the state actively support and encourage enterprises to adopt advanced technology, comprehensive development and utilization of renewable resources recycling cycle of economic projects, especially those scarce strategic resource reserves, such as tungsten, molybdenum, antimony, tin, cobalt, nickel, tantalum, niobium, bismuth, gold, silver, platinum, palladium, rhodium, rare earth, copper, aluminum, lead, zinc and other scrap metal resources, the development of a renewable resource project, equal to the same amount of metal the size of the development of a mine. Hebei wire and cable recycling, cable recycling, Shengxin recycling scrap metal recycling scrap metal from the Linyi City Shengxin Limited. Linyi City Shengxin scrap metal recycling Ltd. (shengxin.tz1288.com) strong, credible, in Linyi, Shandong scrap metal industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Shengxin scrap metal recycling into the brilliant and you work for a better future!
