The innovative process can accurately separate ultra-fine powders of different specifications from 1 micron to 150 nanometers or less from powders with a wide particle size distribution. This technology is the first in China and fills the gap. The production technology and process route can be simplified, and it can achieve high efficiency, low cost, and industrial batch production. It can be environmentally friendly during the separation and classification process, which is in line with the country's environmental protection and 2025 high-end equipment manufacturing development goals and requirements.
Technical R & D background
Ultrafine powders are recognized as the origin of new materials because they exhibit different physical and chemical properties from ordinary materials. All material compositions are roughly divided into three categories: metallic materials, non-metallic materials and polymer composite materials. Ultrafine powder industry is a comprehensive technology integrating multiple disciplines. It is closely related to various industries and departments such as mining, metallurgy, chemical industry, building materials, light industry, food, agriculture, medicine, environmental protection, machinery, energy, information, and military industry.
industry development status
With the development of high-tech in my country, higher and higher requirements have been put forward for material technology. In the use of modern industrial fields, ultra-fine powder products are often required to be in a certain particle size distribution range, while ultra-fine powder produced by mechanical methods is often in a wide particle size distribution range."Ultrafine powder-Fine classification" is an industry pain point that needs to be solved urgently in the field of basic materials in my country. For this reason, fine separation and grade treatment of the powder are needed to increase its use value.
Technical product introduction
Through study, the project team summarized all domestic and foreign classification technologies and principles for ultra-fine powder, and integrated gravity, centrifugal force, inertial force, electric field force, magnetic field force, and thermal gradient force field... Such as grading technology and integration, it has been successfully developed after more than 6 years of hard work. Experiments have confirmed that ultra-fine powder can be separated from relatively coarse powder, and the obtained product not only has a small particle size, but also has a particle size distribution within a controllable range.
technical advantages
This technology is the first in China and fills a domestic gap. Compared with peers, the production technology and process route are simplified, and can achieve high efficiency, low cost, industrial production, and can be environmentally friendly during the separation and classification process, which is in line with the country's environmental protection and 2025 high-end equipment manufacturing development goals and requirements. Compared with peers, the relative investment in this project is only about one-quarter of that, and the advantages are very obvious. The market space is huge, and at least 1 million tons of high-end powders need to be finely classified in China.
