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
Copperpowder is one of the important raw materials of metallurgy industry, its consumptionis in second place after the iron powder. Except used as raw materials for thepowder metallurgy materials, the directly application of copper powder is veryextensive, its consumption is only second to aluminum powder. Industry producecopper powder methods are mainly have three kinds: (1) electrolytic method, thepowder with high purity, large range of applications, is the main productionmethod that most countries still used today, but there is large powerconsumption, environmental pollution and other shortcomings; (2) oxidereduction method, the United States atomization granulationoxidizedreductionprocess as representation, the powder properties, varieties can be replaced bycopper powder, meet the application requirements, and overcomes thedisadvantages of electrolysis; (3) Water metallurgy method, have leaching-highpressure hydrogen reduction, leaching-replacement or electrolysis process. Oftenused for low-grade copper material utilization. The consumption of copperpowder accounts for most in industrial applications, because most powdermetallurgy copper parts are still suitable for used cold process-sintering pre-mixedpowder (copper powder adding elements powder such as tin, lead, zinc powder andmechanical mixing), or part of the pre-alloyed powder (the mixed powder throughheat-treated to make diffusion alloying) to produce, such as used foroil-bearing tin bronze powder.Tinpowder, lead powder and zinc powder is mainly used atomization method to produce.Tin, lead, zinc and copper-based alloys is the main alloying elements, so thatin the extensive use of copper powder to produce copper-based powder metallurgymaterials and products should also add tin powder, lead powder and zinc powderas a raw material component. In addition, it also directly applied in preparingsolder flux, rubber and plastic additives, fireworks, metallic pigments and soon.Tungsten,molybdenum rods, plates, wire is used tungsten, molybdenum powder as rawmaterial to further purify, process to form, also can be through tungsten,molybdenum powder metallurgy process directly produce tungsten and molybdenumshaped products. Tungsten powder also the important raw materials of cementedcarbide industry prepare tungsten carbide powder. Tantalum powder is mainlyused in manufacturing capacitor, is prepared by potassium tantalum fluoride bythermal reduction of sodium metal. After tantalum powder made of bars though electron beam melting purifiedand then by hydrogenation, crushing, dehydrogenation process can be preparedhigh purity tantalum powder and tantalum alloy powder. Niobium powder is madefrom aluminum thermal reduce niobium oxide and then hydride, crushing,dehydrogenation process the resulting niobium metal. Titanium powder isgenerally produced by sodium or magnesium thermal reduction method, obtainedspongy titanium (titanium sponge) can be further purified, processing titaniumand titanium alloy materials, can also be hydrogenated, crushing, dehydrogenationto make of titanium powder. Manganese powder generally produced by mechanical crushing method and used materialsare electrolytic manganese metal, industrial application methods includemilling method, ultrafine grinding method, vertical mill grinding method and soon.Noble metal powders are mainly the silver powder applications. Silver powder used formanufacturing battery electrodes and silver-based electrical contact materials,used for the electronics industry conductive inks, ointments and adhesives,etc., also used in dental amalgams, water purification and catalyst. Theelectricity, electronics industrial silver powder is produced by chemicalprecipitation method, with high purity, fine grain size and other characteristics,a small amount is also produced by atomization. The production method of gold,platinum and palladium powder are similar to silver powder, mainly used as conductivematerial in the electronics industry.Source:http://www.mhcmp.com
