    1. Nano diamond is added to lubricating oil and coolant
    The application of nano-diamond in lubricating oil, grease and coolant is mainly used in machinery industry, metal processing, engine manufacturing, shipbuilding, aviation, transportation. Adding nano-diamond to lubricating oil can increase the working life of engines and transmissions and save fuel Engine oil, the friction torque is reduced by 20-40%, and the friction surface wear is reduced by 30-40%. 1000 kg of engine oil consumes 0.1-0.2 kg of nano-diamond. The application of nano-diamond in lubricants must solve the problem of stable suspension, which has been solved by companies This problem.
    2. Nano diamond-polymer composite
    Nano-diamond polymer composites are used in aviation, automobiles, tractors, shipbuilding, medical, chemical, petrochemical, globe valves, protective coatings and wear-resistant coatings. Fluoroelastic rubber and polysiloxane-based high-efficiency coatings have been developed Layer. The elastic strength properties of polyisoprene rubber, styrene butadiene rubber, nitrile rubber and natural rubber have been greatly improved. Adding nano-diamond to rubber can reduce wear by an average of 2 to 4 times, increase fracture resistance by 30%, and improve Destruction temperature 15%.
    Epoxy resin glue containing nano-diamonds has higher adhesion and cohesion. The addition of nano-diamonds to the polymer can improve its strength, wear resistance and thermal aging resistance. 1000 kg of rubber (polymer) consumes nanometers Diamond 1~5kg, 1000m2 polymer coating consumes 1~5kg diamond.
    3. Sintered body
    In the field of abrasives, nano-diamonds are mainly used to mix with transition metals to produce high-strength and low-porosity diamond sintered bodies. Its micro-hardness can reach 6000-7000kg/mm2. It can be used to process soft or brittle materials with very high surface roughness. Low. If pre-epitaxially grown carbon or add static pressure synthetic diamond powder, the microhardness of the diamond polycrystal obtained by sintering under the pressure of 10~12GPa can reach the level of natural diamond single crystal. It can be made into a drill bit to drill high-strength rock formations. Exceeding the performance of CB-СП (Russia) polycrystalline. When compressing the diamond powder synthesized by static pressure, using nano-diamond as a component of the silicon impregnating material can almost double the yield of the sintered body, and the compressive strength is 1.7GPa Increased to 2.2GPa. This sintered body is used as a cutting element for drills.
    4. Magnetic recording system
    Nanodiamonds can also be used in magnetic recording media such as magnetic tapes and magnetic disks, acting as wear-resistant additives and physical modifiers. Nanodiamonds are added when electrochemically coating composite magnetic recording films to improve the performance of magnetic recording devices. Add nano Diamond can reduce ferromagnetic material particles, increase recording density, reduce abrasive wear and friction coefficient.
    5. Add to intermetallic compound
    Copper, tin, and zinc intermetallic compounds containing nanodiamonds can be used as friction parts under very harsh working conditions. At this time, plastic and liquid lubricating materials are often extruded. Nanodiamonds are ideal component materials for copper-zinc or copper-tin alloys ( The content does not exceed 15% by volume). After adding nano-diamond, the friction is reduced to 1/2~1/6.
    6. Medicine
    Nanodiamonds can also be used in medicine for the treatment of tumors, gastrointestinal diseases, and skin diseases. It is non-toxic, non-carcinogenic or rusty. Nanodiamonds are super active adsorbents and bioactive substances locating agents, which can greatly enhance drugs Efficacy
