Talk About Ultra-fine Diamond Dust Abrasives

Ultra-fine diamond dust abrasive, with its excellent hardness and thermal conductivity, is widely used in various precision machining and high-tech fields. This article will delve into the characteristics, uses, and applications of diamond dust abrasive in new materials, to help understand the multiple values of this important industrial raw material.

Characteristics of Diamond Dust Abrasive

Diamond dust abrasive is an ultra-fine powder obtained by crushing diamond crystals. These diamond dust abrasives are typically subjected to fine grinding processes to ensure a wide particle size distribution. Diamond dust abrasives have a very high thermal conductivity, with values reaching1900~2000W/(m·K), making them the best known materials in terms of thermal conductivity. This characteristic makes diamond dust abrasives especially advantageous in manufacturing high thermal conductivity composite materials. They can significantly improve the thermal conduction of materials, enhance the heat dissipation of workpieces, thereby extending the workpiece's lifespan and reducing operating costs.

Main Uses of Diamond Dust Abrasive

Diamond dust abrasive, due to its extremely high hardness and stability, has become a key material in various industrial applications. Diamond micro powder, as a type of ultra-fine diamond dust abrasive, usually ranges from0-0.5microns to6-12microns in particle size, and is widely used in grinding and polishing. Its specific uses include:

Polishing materials

Fine diamond dust abrasive such as 0-0.5micron diamond micro powder is often used in high-precision polishing processes, providing excellent surface finishes for materials such as hard alloys, ceramics, and optical glass.

Grinding materials

Larger diamond dust abrasives, such as10-15microns to22-36microns in particle size, are suitable for grinding various hard materials. These abrasives can effectively remove the rough surface layer of materials, enhancing processing efficiency.

Functional materials

Diamond dust abrasivescan also be used as functional materials beyond mechanical processing. For example, mixing diamond micro powder into thermosetting resins or ceramics can produce composite materials with excellent thermal conductivity and low thermal expansion, used for high-performance thermal control devices in the electronics industry.

Applications of Diamond Dust Abrasive in New Materials

Preparation of high thermal conductivity composite materials

Diamond dust abrasive, due to its high thermal conductivity, is an ideal choice for preparing high thermal conductivity composite materials. By mixing diamond dust abrasive into thermal conductive composite materials, the thermal conductivity of the materials can be significantly improved while maintaining good impact resistance. This high thermal conductivity composite material is widely used in heat dissipation management of electronic devices, effectively reducing the temperature rise of devices, improving heat dissipation performance, and thus enhancing the operational stability and lifespan of the devices.

Enhancing the performance of new sheet materials

Mixing diamond micro powder with metal sheets such as nickel sheets or stainless steel sheets can produce sheet materials with high thermal conductivity and low thermal expansion. This new material has significant applications in the electronics industry, useful for manufacturing high-density, high-efficiency devices, enhancing thermal control capabilities. Due to the excellent thermal properties of diamond micro powder, these new materials are not only lightweight but can also effectively control heat, helping to improve the overall performance of electronic products.
