Sphere Shape Synthetic Nanodiamond Powder For Superfine Polishing

ND30 To ND800 Sphere Shape Nanodiamond Powder 99 Percent Purity

Description:

Harmony Nanodiamond Powder is formed with tiny crystals that are no more than 20nm. Special detonative synthetic condition produces sphere shaped diamond with rich functional group on the surface. Its specific surface area is lifted an order of magnitude contrasted with monocrystalline diamond. It possesses characteristics of both diamond and nano functional materials.

The nanodiamond retains comprehensive performance of diamond. It is harmless and has good biological compatibility to human body. On radar wave, ultraviolet, infrared, it has good absorption and huge transmittance rate. Nanodiamond also has excellent cold cathod field emission effect.Its surface is rich of functional groups such as carboxyl, hydroxyl. It can easliy combine with mental, rubber, plastic polymer, fabric surface,etc. It is expected to be widely used in machinery, electronics, chemical, medical and other fields.

This type of nano diamond is formed by detonation wave, which has high wear resistance, good corrosion resistance, high thermal conductivity, high dispersion stability and perfect finish of the workpiece surface. Applied in polishing and grinding of hard disc, magnetic head, gem, ceramic, glass and hard alloy, as well as oil, lubricants and other additives, in order to reduce friction and increase the service life.

Diamond is a simple crystal composed of carbon element formed under high pressure and high temperature conditions in the deep parts of the earth. Diamond is a colorless octahedral crystal whose composition is pure carbon, which is linked by carbon atoms with four-valent bonds. It is the hardest substance known to exist naturally. Since the CC bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons, so the hardness of diamond is very large, the melting point is 6900 degrees Fahrenheit, and the ignition point of diamond in pure oxygen is 720~800℃. It is 850~1000℃ in the air, and it is not conductive.

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:

- Nano diamond use for precise polishing
Polishing pastes and suspensions make of diamond nanopowder are used in semiconductor silicon wafers, computer magnetic heads, radio, medicine, machinery manufacturing, gemstones and other industries to precisely polish materials.

- Nano Diamond Gasoline Engine Oil
The addition of diamond nanopowders in the lubricating oil turns the sliding friction into rolling friction. The surface of the friction pair is gradually modified to form a hard and slippery metal carbide. Its anti-friction and anti-wear effects are unmatched by organic chemical methods and can improve the engine. And the working life of the transmission device, save fuel oil, reduce surface wear and so on.

- Reinforced rubber and resin
It is used to make reinforced rubber and reinforced resin. This application plays a significant role in improving material thermal conductivity, polymer degradation temperature, strength and wear resistance. It can increase its strength by 1 to 4 times and significantly improve its wear resistance and Tightness.

- Nano diamond use for super hard coating
Nano-diamond composite coating has the properties of super-hardness, high wear resistance, heat resistance and corrosion resistance, and can be used for the coating of metal surfaces and rubber, plastic, glass and other surfaces. Compared with ordinary coatings, the hardness is increased by 50%, and the wear resistance is increased more significantly.
