Dark Grey Nano Diamond Powder For Superfine Grinding & Polishing

Refractory Dark Grey Nano Diamond Powder For Antifriction

Description:

Nanodiamond is ball-shaped with the particle diameter ranging from 4 to 15 nanometers and an average diameter of 7nm. It is hard, chemically constant, abrasion-resistant, super corrosion-resistant and high heat conductivity, refractory, and highly conductive. It has big special surface ranging from 280 to 420 m2/g, high surface energy, rich surface functional group such as oxalyl, carbonyl, hydroxy group. It also has good biological compatibility and cold emission function. Those advantages make nanodiamond and import role to promote the competitive power of traditional industry in navigation, transportation, medicine, precision polishing, lubrication, composite materials.

Depending on requirements of different applications, nano diamond primary products should pass procedure of purification, surface modification and precise grading treatment, which are our exclusive technology. Different post-processing can provide all series of nano diamond products with full specifications and types.

In theory nano diamond powder can be applied for grinding and polishing, and nano diamond powder for polishing systems have the following advantages:
- Ultra-fine size nano-diamonds ensure minimum surface roughness and stability of the polishing system colloid.
- The chemical stability of nanodiamonds, which can be chemically used for the reduction of active additives and polishing systems in polishing systems.
- Reduce the amount of material on the polished surface and reduce material loss.
- Due to the ion exchange and adsorption activities of nanodiamonds, the activity of ions and molecular products on the surface of nanodiamonds can be reduced, that is, the purity of the surface is ensured.
- The agglomerate structure of nanodiamond agglomerates facilitates coalescence regulation in suspension polishing systems.
- This system is not poisonous.
- Polishing system with nano-diamond can improve the quality and competitiveness of polishing products to ensure the processing of difficult-to-machine materials.

Storage of nano diamond powder: It should be sealed and stored in a dry, cool environment, away from direct sunlight.

Application for  Nanodiamond Grade HID ND:

- Super fine polishing. The surface roughness of polished workpieces could reach angstrom-level without scratches, which can satisfy the most rigorous polishing applications demand.
- Lubricating and antifriction. Nano diamond can be used as lubricating oil additives. The sliding friction will be changed into rolling friction. Which can reduce the friction coefficient and significantly improve the friction performance and also prolong the service life.
- Composite plating and spraying on the surface of various workpieces. Nano diamond can enhance wear resistance, corrosion resistance, impact toughness and hardness of the workpieces' surface,
- As rubber and plastics additives, nano diamond can significantly enhance its wear resistance, puncture resistance, tensile property and also slow down the ageing process.
- High purity nano diamond will not cause biological rejection, meanwhile it can be widely used in medical, biological and cosmetic fields because of its big specific surface area, strong adsorption potential.
