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
In recent years, it was risingsharply due to the rapid development of the world's battery industry. There aremainly 10 cobalt powder enterprises in China, the total productioncapacity is 1850 tons/year. Chinais also one of the world's major cobalt consumption countries, the consumptionaccounts for about 10% of the total world consumption. At present, China's demandfor cobalt is 3000 tons per year. In cemented carbide industry, cobalt powderis mainly used for adhesives, an average content is about 10%, the consumptionreached 800 tons/year, accounted for 33% of total consumption, and the averageannual growth is 5.4%. From the international market demand, the world's cobaltconsumption has been on an upward trend since the 1990s, the average annualgrowth is 2.6%. In 1998, the world's cobalt consumption was reached 29,500tons. Based on the data reported, in the next few years, the world's cobaltpowder consumption will increase 8,000 to 10,000 tons, the used amount isrising sharply. Powdermetallurgy is an ancient industry, a kind of traditional metallurgicalprocesses. Ancient people have been used gold, silver, copper, bronze and someof its oxide powder for coating, applied to pottery, jewelry and other utensilscoloring, decorate. Americans produced tungsten wire by the powder metallurgymethod, laid the foundation of modern powder metallurgy industry. To thebeginning of last century, metallurgy skills gradually get improved. AfterWorld War II, metallurgy skills gained rapidly developing, and gradually form amodern powder metallurgy industry. Cobalt powder industry is mainly used metal powder as raw material for processing molding. In the modern development,it also has the process of mixing metal and nonmetal powder to make newmaterials. Therefore, the powder metallurgy process is of great significance forcapital savings and waste resources recycling. China is a large country that shortage of cobalt powder resources butdemand for a large amount, cobalt oxide is mainly used in carbide smelting,lithium battery manufacturing, ceramic color glaze production and otherindustrial fields. It is a long history of china produced cobalt oxide by alloyscrap which containing cobalt powder, in the production, marketing, applicationand other aspects of cobalt oxide, there is already a good industrial base andfavorable conditions, on this basis, we should improve the productiontechnology and equipment level, and expand production to meet marketrequirements. Cobalt powder and its products are important strategic materials, especiallyshould pay close attention on the military application, it should do a good jobon the protection and development work for cobalt and its products. In order tofaster developed cobalt oxide production, the supply of raw materials is veryimportant, can be imported a number of cobalt-containing alloy scrap from theinternational market to meet the production requirements of the raw material. After1950s, Chinese economy was rapidly developed. In addition to cobalt powderindustry, various industries were started and fast developed. It was not until1970s, with the socialist market economic system gradually established, China achievedgreat development in various industries, the technology of metallurgy industrywas gradually improved. Today, Chinese metallurgical industry was completed thetrue sense of rapid development. ArticleSource:http://www.mhcmp.com
