Classification and Application of Diamond Micron Powder
Diamond micron powder refers to diamond particles finer than 60 microns, including single crystal diamond powder and polycrystalline diamond micron powder. With the rapid development of nanotechnology, a new type has been independently developed among the two original diamond-like powders: nano-diamond micron powder.
Single crystal diamond micron powder
Single crystal diamond micron powder is produced by synthetic diamond single crystal abrasive grains, which are crushed and shaped, and produced by a special process method of superhard materials. Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, polishing, etc. It is an ideal raw material for grinding and polishing hard alloys, ceramics, gems, optical glass and other high hardness materials. Diamond micron powder products are tools and components made by processing diamond powder.
Polycrystalline diamond micron powder: Polycrystalline diamond micron powder is made of graphite by a unique directional blasting method. The shock wave of the directional blasting of the high-speed explosive accelerates the flight of the metal flying piece and hits the graphite piece to cause the graphite to be converted into polycrystalline diamond. Its structure is very similar to natural diamond, which is formed by the combination of unsaturated bonds and has good toughness.
Nano diamond micron powder
Nanotechnology is a high-tech that emerged after the 1990s. Nanoscale diamond is composed of diamond particles with a nanometer size, that is, one billionth of a meter. It is a new material synthesized by explosive technology in recent years. It not only has the inherent characteristics of diamond, but also has small size effect, large specific surface area effect, quantum size effect, etc., thus exhibiting the characteristics of nanomaterials. The diamond synthesized in the detonation wave has a cubic structure, the lattice constant is (0.3562+0.0003) nm, the crystal density is 3.1g/cm³, and the specific surface area is 300m²/g~390m²/g. After being treated with different chemical methods, a variety of different functional groups can be formed on the diamond surface, and this diamond crystal has a high adsorption capacity. Huanghe Whirlwind is such a professional diamond micron manufacturer in China.
Since the mid-1990s, due to the needs of the development of high-tech industrial technology and cutting-edge science and technology, the production of diamond micron powder has the following development trends:
The particle size classification is getting finer and the size range is getting narrower and narrower
At present, many industrial and technical departments require the use of 0 to 4um diamond micron powder. As far as 4um fine diamond micron powder is concerned, the American National Standard ANSIB74.20-1981 formulated in 1981 stipulates that 4um fine diamond micron powder has only three levels: 0～1, 0～2, 2～4. Established in 1984 The industry standard 1DA stipulates that 4um fine diamond micron powder has 5 grades: 0~1/2, 0~1, 0~2, 1~3, 2~4.
Ultra-high grinding performance diamond micron powder
The institute has been vigorously researching and developing the application of synthetic diamond micron powder abrasive paste. According to them, the production efficiency of diamond paste applied to polishing high-precision parts is 1 to 2 times higher than that of paste made of non-diamond abrasives, and the finish of processing can be improved by one level.
The application of diamond grinding paste is very wide, and it is often used for the fine grinding and polishing of some high precision and high surface finish components. For example, it is used for metallographic specimens, drawing dies, clocks and other industrial gem bearings, stamping dies and dies, gauges and block gauges, aircraft high-precision hydraulic transmission parts and internal combustion engine parts, precision instrument components, radar equipment, various transistors and Fine grinding or polishing of gyroscope parts, etc. In addition, it is also used for the grinding of diamond, cemented carbide, glass, quartz, ceramics, ruby, sapphire, germanium, silicon and other hard and brittle material components, as well as the polishing of cast iron, steel, non-ferrous metals and alloy parts; titanium, tantalum, zirconium And other difficult-to-process rare metal parts for precision grinding, etc.
Undoubtedly, diamond micron powder is an indispensable abrasive for the development of high, precise and sharp products. Its application has very broad prospects. Its application fields are constantly expanding. At present, industrialized countries are investing a lot of money and Manpower research on the synthesis of new types of industrial grade diamonds will open up new opportunities for the application of synthetic diamonds in science, technology and industry.
