What are the application aspects of diamond powder?
As a kind of super hard abrasive, diamond powder has excellent grinding ability, and has been paid more and more attention by industrial developed countries. The grinding ability of diamond powder includes the grinding ability of the workpiece and its own wear resistance and crushing resistance, which depends on its microhardness, particle size, strength, particle shape and thermal stability and chemical stability.
To sum up, the application of diamond powder as an abrasive has three aspects:
(1) Used for resin bonding tools, metal bonding tools and electroplating tools;
(2) Used for the fine grinding or polishing of various precision components in industry, science and medicine;
(3) as a fine abrasive for mold processing, jade polishing processing, gem bearing processing applications.
In addition to the application of diamond powder as an abrasive material, another major use is as a functional material. Such as the use of its thermal and electrical properties. A new material with high thermal conductivity and low thermal expansion can be prepared by mixing diamond powder into thermosetting resin polymer, cellulose, phenolic resin or ceramic sheet. By mixing diamond powder into metal sheet, such as nickel sheet or stainless steel sheet, a new type of sheet material with high thermal conductivity, low thermal expansion and light weight can be made into a high-density and high-energy device for thermal control in the electronic industry.
From the form of diamond used as grinding materials, according to the figures published in the relevant information, more than 60% of the world's industrial consumption of diamond powder is used to make diamond gypsum, diamond powder mixture and diamond powder grinding fluid.
