Quality Factors and Quality Control of Diamond Micro-powder

How to evaluate the quality of diamond micro-powder? It is a common concern by diamond micro-powder manufacturers and users.

Practice shows that we must follow a strict control on the following four indicators in order to get good quality diamond micro-powder: A, The size and content of coarse particles; B, The distribution range of particle sizes; C, The particle shape; D, The strength of diamond raw materials.

The distribution range of particle sizes and the size and content of coarse particle sizes are both very important. The strength of micro-powder is determined by the immanent quality of diamonds, and also directly affects the particle shape after crushing and plastics.

The quality testing of micro-powder is an important link to ensure the micro-powder product quality being in accordance with the prescribed standards. Only to choose appropriate testing instruments and serious treatment can help to produce high quality micro-powder to meet the requirements and customer needs. Thus, since the mid-1980s, there have been some modern equipment and instruments to produce diamond micro-powder at home and abroad.

But China's diamond micro-powder production equipment and process methods still have gap compared with the industrial developed countries. They are not bad on the product granularity partition, but have some difference in the variety and brand of products. What’s more, their product quality can not completely meet the needs of high-end customers at home and abroad, and affect the normal development of domestic and foreign markets. Therefore, it is recommended that the industry should organize and coordinate enterprises and experts to make systematic research on crushing, plastics, grading equipment and process methods in the production of diamond micro-powder, and use advanced technology to produce high quality diamond micro-powder, to satisfy the demand for high quality micro-powder in the high and new technology processing field at home and abroad.
