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 Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The
Cobalt is a shiny steel-gray metal, meltingpoint is 1495, specific gravity is 8.9.Cobalt is a ferromagnetic metal, similar with iron and nickel phase inhardness, tensile strength, machinability, thermodynamic properties and electrochemicalbehavior. Cobalt metal is very stable in the wet air and water at roomtemperature, also does not react with alkali and organic matter. Themajor products of cobalt have cobalt-based chemical products, metal stateproducts of cobalt (cobalt sheet, cobalt powder). With the product processing technology deepening and productupgrades, value-added cobalt products have been increasing. The vast majorityof cobalt are byproducts, which generated in exploiting copper and nickel,individual production is less likely, its production scale was affected bycopper, nickel mineral development in a large extent. The cobalt yield of theChinese market is depending on the supply of the world's cobalt markets cobaltore and intermediate products and the like. Battery material is the mostimportant consumer materials of cobalt, accounting for about 60% of the totalcobalt consumption. The main constituent materials of the lithium-ion cellincludes electrolyte, insulating materials, positive and negative materials.Lithium cobalt is one of the most common metal materials. Lithium battery ismainly used in mobile phones, laptop field, electric bicycles and new energycars field. The new energy vehicles will be the main growth point of electriclithium demand. Another major use of cobalt is in the production ofhigh-temperature, heat-resistant, corrosion-resistant cemented carbide.Cemented carbide is composed of hard materials (tungsten, titanium) and good toughnessparticulate material (cobalt, nickel) extruded adhesive. Cemented Carbide iswidely used as tool material, such as turning tool, milling, planer, drill,boring knife, for cutting cast iron, nonferrous metals, plastics, chemicalfiber, graphite, glass, stone and ordinary steel, also can be used to cut heat resistant steel, stainless steel, highmanganese steel, tool steel and other hard to processing materials. Cementedcarbide can be used to make drilling tools, mining tools, boring tools, measuringtools, wear parts, metal grinding, cylinder liners, precision bearings,nozzles. Superalloy is one of another main consumption of cobalt, in 2011,superalloy accounts for nearly 20% of the global cobalt consumption, while China is only4%. The proportion of consumption in China will be bigger and bigger. Superalloyis the alloy which can withstand stress and has anti-oxidation or corrosionresistance at 600-1200. In theconsumption of high-temperature alloys, aerospace, energy, propulsion,industrial, automotive industry and other areas respectively accounted for 64%,24%, 5%, 3%, 2% and 2%. Aerospace engine is the main consumption part of superalloyin aerospace industry. According to metal powder supplier, magnetic metal is another purpose of cobalt. Magnetic materialsplay a very important role in the electronics industry and other high-techfields. Cobalt can be used as high-grade glass and ceramic color dye, cobaltused in the glass ceramic industry has been relatively stable. Cobalt is alsowidely used in various hydrogenation catalysts of petroleum refining.Cobalt-based catalysts, such as cobalt acetate has an important role in thesynthesis of the catalyst. Currently,the price of cobalt was at the bottom of history. In the long run, the supplyof cobalt is limited by copper, nickel mining, has diverse demands and there isa certain inevitability in demand growth. Especially in the field of lithiumbatteries, there is not appeared better alternative, if the new energy vehiclesget promotion, then the global cobalt consumption will be greatly increased.
