Ultra detonated polycrystalline diamond powder-Harmony Industry Diamond (H.I.D)

Polycrystalline diamond by detonation

Grade HID PD

Our polycrystalline diamond is produced by detonation with high energy explosive, the high explosive heat and high detonating pressure change the graphite into poly diamond, and its structure is similar to natural carbonado diamond. Because synthesis time is very short, there are some lattice defects inside the crystal, almost all the diamond particle is composed by integrating the micro crystallites size of less than 20nm together through sharing the crystal face. In processing special material, poly diamond will not scratch the workpiece’s surface, because its compressive strength and impact strength are far below common diamond products. Under certain pressure, microcrystal grain of poly diamond particle surface will continuously peel off and form new cutting edge.

These characteristics provide solutions for grinding and polishing some high hardness special materials rapidly. Experiments show that the removal rate of poly diamond is 2-4 times higher than common diamond and without scratches. Based on years of mature experience of monocrystalline diamond powder, we have successfully resolved the technical processing issues of polycrystalline diamond, such as crushing, reshaping, purifying, grading etc. We supply bulk polycrystalline diamond powder consistent with the standard requirements of monocrystalline diamond powder.

Polycrystalline like diamond

Grade HID PLD

Polycrystalline diamond-like micropowder is a new type of grinding material with high-quality diamond as raw material, which has been processed by a special process. The edges of the diamond particles are passivated and honeycomb-shaped, which can effectively prevent deep scratches on the surface of the workpiece. Compared with traditional diamond micropowder, it has the advantages of high grinding efficiency, low surface roughness of the workpiece and less residual particles on the surface of the workpiece.

Product feature

Strong cutting force: There are a large number of sharp cutting edges on the surface of the particles, and the cutting force can reach 2-4 times that of single crystal diamond powder;
High polishing precision: The surface cutting edge of single crystal diamond micropowder particles is large and hard, which is prone to deep scratches, while the surface cutting edge of polycrystalline diamond micropowder particles is small and low in hardness, and the Ra value of the workpiece surface is significantly reduced after polishing;
Strong holding power: The surface of the particles is rough, and the combination with the binder is more firm, which can significantly improve the holding power of abrasives in various diamond products and increase the service life.

Application

It is suitable for grinding, polishing and surface treatment of precision industrial devices such as hard disks, magnetic heads, semiconductor materials, gemstones, diamonds, and ceramics.
