Advantages in processing fine nickel powder of Chinese smelters
The future development of ultrafine nickel powder technology mainly focuses on three aspects of preparation, properties and applications of ultrafine nickel powder. The preparation technology studies the preparation principle, preparation methods and preparation equipment.
It aims at preparing a superior ultra-fine powder with characteristics of narrower particle size, more uniform distribution, better dispersion, and surface performances. Equipment has large production capacity, high output, low energy consumption and good wear resistance. It can produce no pollution with a long life time.
Chinese smelters fine nickel powder production process is simple. It has continuous production, high degree of automation and the product quality is stable, safe and reliable. The performance objective of the study is modified or composite processing, the particles reach the ideal performance of the required particle by particle design. Applied research focused on the ultrafine nickel powder in various fields of national economy, and solves the various problems associated with the application.
The basis of the analysis of the market, the Chinese smelter metallurgical engineers, engineers and other professional research group of a dozen people, access to a lot of relevant information, the actual situation, developed their own set of ultrafine nickel powder production technology program. Program 200g small test validation and 200kg medium-sized technology demonstration test, according to the ton mass. Product performance by the most authoritative test and analysis of powder research institutions, has reached the Canadian nickel industry product standards, some of the models than its product standards.
The project process based on the characteristics of the nickel, as a raw material, the use of the chemical production of ultrafine nickel powder. The process has the following characteristics: short production cycle, investment in small-scale, high technical content. Nickel recovery, the whole process of nickel efflux, the overall recovery rate of up to 99% or more. The whole process no pollution and is environmentally friendly process. Begin to control the size distribution in the middle of complexation processes, the production of different types of products, production operability of the strong middle part of a small, high degree of automation, low labor intensity.
Production of ultrafine nickel powder plasma method, mechanical crushing method and carbonyl. The adoption of chemical production mainly has the following advantages: raw materials used in production for nickel, dissolved in a chemical system of nickel salt, low impurity content, high product quality. In the process, the removal of organic matter, income dispersion, and high mobility. Easy filtration, precipitation, dispersion, complexation of nickel salt and the advantages of easy to wash and operable.
The washing process, using high pure water equipment, such as calcium, magnesium, sodium, chloride ion content is much lower than similar products. The drying process of the nickel salt, no agglomeration, compaction phenomenon, particle size distribution. The new nickel powder reduction furnace, to avoid the phenomenon of spontaneous combustion of nickel powder baked.
Ultrafine nickel powders product quality is improved through breakthroughs in key technologies. The metal powder supplier makes ton mass production for market. The market reflects the situation and has greatly improved the performance of their products. If the ultrafine nickel powder can achieve large-scale production, it will replace imported products.
The independently research work in theory and applications of the ultrafine nickel powder technology systems is still little. Chinese smelters make breakthroughs in key technologies and process improvements of ultrafine nickel powder. Currently, they has produced marketable ultra fine products.Source:http://www.mhcmp.com
