Gansu nano-diamond reaches the international advanced level

The “Nano-Diamond Extended Product Grinding and Polishing Agent” completed by private high-tech company Gansu Lingyun Nanomaterials Co., Ltd. has passed the appraisal in Lanzhou, and the grinding effect and efficiency have reached the international advanced level.
The nano-diamond powder produced by Gansu Lingyun Co., Ltd. has a particle size of 4-16 μm and has a hardness close to that of natural diamond. It is an ideal abrasive material. On the basis of this, the polishing agent has good appearance, rheological properties and storage stability, and the optimal production process has been determined, forming an annual production capacity of 500 kg. The nano-diamond abrasive paste developed by Lingyun Company grinds the ceramic ball to a surface roughness of 6.3 nm, which is superior to the conventional micro-diamond polishing paste, and the roughness has exceeded the highest level (level 3) accuracy of 0.012 μm. The results of the grinding test on carbon steel show that the microscopic unevenness of the profile is only 1/5 of the conventional abrasive paste, and the grinding time is shortened from 8-10 hours to 2 hours.
