Industrial Saw Grit Diamond Powder Grade HID 920 For Cutting Wheel

18/20-70/80 Saw Grit Industrial Diamond For Cutting Wheel

Description:

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.

HID Saw Grit Diamond include HID90 & HID80 series, both of which has complete specifications, various sizes and grades. They are able to produce variety tools for stone, construction and mining industries. The diamond grit particle character (size, strength, crystallinity) plays a major role in understanding the behaviour of grit application. All have stable quality and are able to meet different requirements from customers.

Stability of Diamond
Diamond has stable chemical properties, acid and alkali resistance. It does not interact with concentrated HF, HCl, or HNO3 at high temperatures. It only works in the melt of Na2CO3, NaNO3, KNO3, or when it is boiled with the mixture of K2Cr2O7 and H2SO4. Slightly oxidized; corrodes in high temperature gas of O, CO, CO2, H, Cl, H2O, CH4.
Diamond also has non-magnetic properties, poor electrical conductivity, lipophilic and hydrophobic properties, and triboelectric properties. Only type IIb diamond has good semiconductor properties. According to the difference in nitrogen impurity content and thermal, electrical and optical properties of diamond, diamond can be divided into two types, type I and type II, and further subdivided into four subtypes: Ia, Ib, IIa, and IIb. Type I diamonds, especially Ia subtypes, are common ordinary diamonds, accounting for about 98% of the total natural diamonds. Type I diamonds all contain a certain amount of nitrogen and have good thermal conductivity, poor electrical conductivity and good crystal shape. Type Ⅱ diamond is extremely rare, contains little or almost no nitrogen, has good thermal conductivity and characteristics of curved crystals. Subtype IIb diamond has semi-conductivity. Because of the excellent properties of type II diamond, it is mostly used in space technology and cutting-edge industries.

Application of Harmony Saw Grit Diamond Powder:
- It is suitable for the production of PCD, metal bond, electroplating abrasive tools, ceramic bond products, etc.
- Diamond powder is also can be used for the grinding and polishing of optical glass, fine ceramics, gemstones and other products and the production of diamond pastes and polishing agents.
- It can be used for wire drawing Mold polishing (with special red powder), sapphire polishing, zircon polishing, watch polishing, tungsten steel mold polishing, cold heading mold polishing, cemented carbide mold polishing.
- Diamond powder can be used for water grinding and fine grinding; it can be used to make ceramic diamond grinding wheels, Resin diamond grinding wheel.
- Optical fiber grinding ceramic ferrule grinding and polishing; optical lens, optical crystal, LED, LCD grinding and polishing; magnetic head, hard disk polishing; micro motor shaft and commutator polishing; diamond powder plating on the surface of some workpieces can greatly increase its abrasion resistance.
