new application field of nano diamond powder

The new application field of nano diamond power:
1. Nano diamond added to lubricating oil and cooling fluid

Nano diamond in the application of lubricating oil, grease and cooling fluid are mainly used in machinery, metal processing, engine manufacturing, shipbuilding, aviation transportation,nano diamond powder added in lubricating oil can improve the working life of the motor and transmission, saving fuel oil, the friction torque reduce by 20 ~ 40%, the friction surface wears decrease by 30 ~ 40% 1000 kg oil consumption nano diamond 0.1 ~ 0.2 kg. Application of nano diamond in lubricationg oil must solve the problem of the stability of suspension. 

2. Nano diamond-polymer complex

Nano diamond composite polymer used in aviation, automobile, tractor, ship manufacturing, medicine, chemical industry, petrochemical industry, cut-off valve, the protective layer and wear-resisting coating. Has developed the fluorine rubber elasticity and polysiloxane efficient coating. Polyisoprene rubber, styrene-butadiene rubber, nitrile rubber and natural rubber elastic strength performance have been improved greatly. Adding nano diamond in rubber can reduce the average wear 2 ~ 4 times, improve the fracture resistance of 30%, increase the damage temperature of 15%.

Epoxy resin adhesive containing nano diamond has higher adhesion and cohesion, adding nano diamond into the polymer can improve its strength, wear resistance and thermal aging resistance. 1000 kg rubber (polymer) consumes 1 ~ 5 kg nano diamond, 1000m2 polymer coating consumes 1 ~ 5 kg diamond.

3. Sintered body

Nano diamond is mainly used to mix with transition metals in the field of abrasives manufacturing diamond sintered body of high strength and low porosity, the microhardness of up to 6000 ~ 7000 kg/was used to soft or brittle materials processing, processing surface roughness is very low. If the epitaxial growth in advance or add static pressure synthesis of diamond micro powder, in 10 ~ 12 gpa pressure sintering polycrystalline diamond microhardness can reach the level of natural diamond single crystal. High strength rock made a drill can reach or exceed the CB - С П (Russia) using the properties of polycrystalline. Suppression of static pressure synthetic diamond powder,Nano-diamond as a component of silicon impregnating material can almost double the yield of sintered body and increase the compressive strength from 1.7GPa to 2.2GPa. Such sintered body is used as cutting element of drill bit.

4. Magnetic recording system

Nano diamond can also be used in magnetic tape, disk, etc. The magnetic recording medium, the wear-resisting additives and the role of physical modifier. Add in electrochemical composite magnetic recording thin film coated with nano diamond, in order to improve the performance of the magnetic recording device. Add nano diamond particles, ferromagnetic materials can be reduced with increase the recording density, lower abrasive wear and friction coefficient.

5. Added to intermetallic compounds

Contain nano diamond of copper, tin, zinc intermetallic compound work conditions are very bad friction parts are available, and then the plastic and liquid lubrication materials were often. Nano diamond is ideal for a copper zinc or copper tin alloy component materials (content no more than 15 volume %). The add nano diamond after make the friction is reduced to 1/2 ~ 1/6.

6, medical

Nano-diamond can also be used in medicine for the treatment of tumors, gastrointestinal diseases and skin diseases.
