Awhile ago, I got an email from one of the "gurus" I follow and it shocked me. The gist of it was this person wanted to trade services for a household item.To say it floored me would be an understatement.What was worse was a few days later t Automation technologies represent a fundamental aspect of any modern industry. The major types of industrial automation solutions, such as DCS, PLC, SCADA, and MES, are used on a large-scale in process and discrete industries.DCS technologie

Nickel is widely used in containprecious metal currency alloy, also application in the process ofelectroplating technology manufacturing anticorrosive layer. The main body ofthe nickel minerals is red nickel ore, millerite, pentlandite all containarsenic, iron and sulfur, of course, in the rock oar pyrrhotite there havepentlandite. Other ore use in mining nickel general contains Co, Cu, Fe, Mg andother impurity. Nickel is usually the main refining in the process, but in theproduction of other metal process it recycled as a by-product form. The world’sbig mining nickel country have Russia,Canada, Australia, Cuba,new caledonia and Indonesia, etc.Nickel is a yellowy and silvery whitemetal, is one kind of metal has the magnetic transition. In the air it is black,qualitative hard, corrosion resistant ability, heat resistance, the plasticityand toughness, and the temperature lower than 340 is magnetic. The characteristics of the nickel is the chemical activity, have agood stability in the air, water, alkali and all kinds of acid, mainly can formcorrosion resistant surface oxidation film produce passivation. Only nickel powder can be burnned, form two oxide of NiO and Ni2O3 andcorresponding two hydroxide of Ni (OH) 2 and Ni (OH) 3. Nickel’s main solublesalt include: acetic acid nickel, nickel chloride, nickel nitrate and nickelsulfate. Nickel salt solution usually appears as green, and anhydrous nickelsalt generally appears as yellow or brown color. Insoluble nickel saltincluding oxalic acid nickel and nickel phosphate, and three kinds of nickelsulfide - NiS,Ni2S3 and Ni3S4. Nickel also can form a large number of valence compounds andcomplex, for example, demethylation oxalyl nickel Ni (HC4H6N2O2) 2, this kindof nickel salt in acid medium show as bright red, which are widely used in qualitativeanalysis of nickel detection field.According to the information provided by metalpowder supplier, as we all know pure nickel production is a multipleprocess of complex process, sulfide ore by primary mineral out nickelconcentrate, and then to complete the process: sintering - melting output matte- converter blowing matte output nickel high matte - high matte grindingfloating separate nickel and copper - using different methods to deal with highmatte output metal nickel. From the ore to pure metal nickel overall can't recoverymore than 70-75%.Nickel is not only the basis material ofmanufacturing nickel alloy, but also an alloy element of other alloy. Atpresent, nickel and its alloy used for special purpose parts, instrumentmanufacturing, machinery manufacturing, rocket technology and equipment, theatomic reactor, for the production of alkaline storage batteries, porousfilter, catalyst, and the components and work piece of anticorrosive electricplating, nickel is considered as important strategic material in the nationaleconomic construction, the resources effective development and comprehensiveutilization has been pay attention to all countries.The application of nickel is determined bynickel corrosion resistant performance, adding nickel to alloy can enhance thecorrosion resistance of nickle. Stainless steel and alloy production field isthe largest nickel application fields. Alloy containing nickel purposes: monelhigh strength and corrosion resistance of nickel and copper ferromanganesealloy have widely application in chemical equipment, shipbuilding field, alsoused in the manufacture of settling basin and cover, etc. Nichromenickel-chromium alloy and chromel chrome nickel alloy with wire form used intransformer, oven, electric iron, heater, etc. Because the tile iron nickelalloy expansion coefficient is very low, can be used in the manufacture ofclock and measuring tape of the pendulum; Because permalloy have excellentsusceptibility, so the Marine cable and power delivery process application;Argentan used in the manufacture of furniture; Al, KeTie nickel aluminum cobaltalloy is a kind of strong magnetic materials, used in the manufacture of havepermanent magnet performance fine tool. Nickel coating have long used fordecoration, used to protect many kinds of alkali metal corrosion.At present, the world nickel consumption issecond only to copper, aluminum, lead, zinc and fifth in non-ferrous metal. Chinawill be a great development potential of the nickel and stainless steelconsumption market, nickel industry development contains huge potential.Source:http://www.mhcmp.com
