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 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

In recent years, the world aluminumindustry has become the main user of the electrolytic metal manganese. In theiron and steel industry, the electrolytic metal manganese also used to be deoxidizerand desulfurizer.According to statistics, the average perton of steel consume electrolytic metal manganese 0.06kg. With the advances in metallurgical technology,efficient steel and injection metallurgy technology has been greatly developed,electrolytic manganese metal powder in the metallurgical industry has beenincreasing, the expanding dosage is beyond above indicators.In recent years, due to the rapiddevelopment of special steel, in particular, the development of China 200series stainless steel, the proportion of manganese metal is growing inmetallurgy. Aluminum-manganese alloy for modern light the US-based buildingmaterials, the decoration engineering materials, anti-corrosion and undergroundengineering support material. In recent years, aluminum-manganese alloy hasentered in residential buildings in china, which greatly expand the manganesemarket.Electrolytic metal manganese is widely usedin metallurgy, medicine, electronics, communications and other fields. With thedevelopment of science and technology, the application of electrolyticmanganese expanding market demand annual growth of about 15%. The Chinesemanganese annual production capacity is up to 80 million tons, accounting for80% of world production. Over the years, the majority of Chinese electrolyticmanganese for export, mainly exported to Japan,Korea, Europe, United Statesand other countries.Electrolytic metal manganese is using manganesestone by acid leaching manganese salt, then sending to electrolyzer to electrolyticprecipitation of elemental metal, the purity of electrolytic manganese is high,manganese is greater than 99.7%, therefore it mainly use in the aviationindustry, metallurgy and non-ferrous metals smelting. Its role is to increasethe hardness of the material of the composite metal, the most widely used arethe manganese-copper alloy, manganese alloy, manganese alloy strength,toughness, wear resistance and corrosion resistance can be improved in thesealloys. Manganese is an indispensable additive in smelting industry,electrolytic manganese processed into manganese powder is themain raw material for the production of manganese tetroxide, the originalmagnetic material widely used in electronics industry is the production ofmanganese tetroxide, the electronics industry, metallurgical industry and theaerospace industry electrolytic metal manganese.Electrolytic metal manganese is with highpurity, and its role is to increase the hardness of the material of thecomposite metal, the most widely used have manganese-copper alloy, manganesealloy, manganese in these alloys can improve the tensile strength, toughness,wear resistance and corrosion resistance.In Chinese electrolytic manganese industry,Hunan, Guizhou,Chongqingmanganese triangle junction is the concentration of manganese. Due to the earlyand rapid development of manganese, now in Xiushan, Songtao has been alreadytight supplying, coupled with the local government repeated collection ofresources compensation, charge dozens yuan per ton if they sent out of country,the prices of manganese ore is accounting for 1/3 of the cost of electrolyticmanganese. Chongqing,Songtao, Xiangxi mine have an common phenomenon that mined disorderly, tens ofthousands tons of reserves only half, and the resource recovery rate is verylow, only about 50%. In mining, abandoning the poor to the rich is seriously,ore grade from 19% down to 16%. But rich ore supply in Guangxi Daxin's reservesare 100 million tons, enough for decades of using. Manganese price is mainlyinfluenced by the relationship between supply and demand of electricity and rawmaterials. Metal powder supplier generallyconcentrated in the south, where usually rely on hydroelectric powergeneration, flood season and dry season on the power quite closely related withthe production of electrolytic manganese. Usually every 4-10 months in the yearhave abundant rainfall, the power situation is better, have normal production.Other months is due to rainfall led to power shortages, the factory productionwill be reduced accordingly.At present, the Chinese electrolytic metalmanganese production mainly to 99.7% (now most of the manufacturers are actuallyup to 99.8%), only a few manufacturers to 99.9% (the market demand of 99.9% issmaller, But many companies are known for the feasibility study report thatthey produce 99.9%), the main raw material – manganese ore as manganese oxideore and manganese carbonate ore two categories, in addition to the exact way isdifferent from before the processes in the system liquid, electrolyticproduction process is basically the same.Source:http://www.mhcmp.com
