Technical Parameters：

Nano-aluminum nitride and ultra-fine aluminum nitride powder are prepared by a special process, with high purity, small particle size, large specific surface area and high surface activity. The powder modified by surface modification does not undergo hydrolysis reaction, and oxygen content Very low (<0.1%), the effect of insulation and thermal conductivity is very obvious. Used in polymer resin, the viscosity is not obvious, it is the best high thermal insulation insulating filler. Nano-aluminum nitride is a diamond-like nitride, which can be stabilized up to 2200 ° C, high room temperature strength, and the strength decreases slowly with increasing temperature; nano-aluminum nitride powder has good thermal conductivity, small thermal expansion coefficient, thermal conductivity The theoretical value of the rate is 320w/mk, which is similar to copper. At the same time, it is highly insulated. The resistivity is above 10 to the power of 15 and can withstand 1400 degrees. It can greatly improve the thermal conductivity of plastics and silicone rubber. It is good resistance. Thermal shock material, strong resistance to molten metal corrosion, is ideal for casting molten iron, aluminum or aluminum alloy; nano-aluminum nitride has excellent electrical insulation and good dielectric properties; nano-aluminum nitride has good injection Forming properties; used in composite materials, good compatibility with semiconductor silicon, good interface compatibility, can improve the mechanical properties and thermal conductivity of composite materials.

Application field

1. Manufacturing integrated circuit substrates, electronic devices, optical devices, heat sinks, high temperature germanium to prepare metal-based and polymer-based composite materials, especially in high-temperature sealing adhesives and electronic packaging materials to improve the heat dissipation performance and strength characteristics of materials. Good application prospects can replace the currently imported micron aluminum nitride;

2. Thermally conductive silica gel and thermal conductive epoxy resin: Ultra-high thermal conductivity silica gel is prepared by using nano-aluminum nitride produced by our company. It has good thermal conductivity, good super-electrical insulation, wide electrical insulation and use temperature ( Working temperature 80-250 ° C), low consistency and good construction performance. The products have reached or exceeded the imported products, because they can replace the similar imported products and are widely used in the heat transfer medium of electronic devices to improve work efficiency. Such as CPU and heat sink gap, high power triode, thyristor components, diodes, heat transfer medium at the slits in contact with the substrate. The nano-thermal paste is used to fill the gap between the IC or the triode and the heat sink, increasing the contact area between them to achieve better heat dissipation;

3. Nano-lubricating oil and anti-wear agent: The modified nano-aluminum-nitride ceramic particles added in the nano-ceramic engine oil act on the friction pair metal surface inside the engine with the lubricating oil, and are activated under the action of high temperature and extreme pressure, and are firm. It is infiltrated into the dents and micropores of the metal surface to repair the damaged surface and form a nano ceramic protective film. Because of the isolation of the film, the friction caused by the relative motion between the parts only acts on the protective film. The nano-ceramic particles transform the partial friction between the friction pairs into a rolling friction like a small ball. Greatly reduce friction, reduce the friction between moving parts to near zero, and provide super anti-wear protection for the engine. By improving lubrication, it can reduce the friction coefficient by more than 80% and improve the anti-wear ability by more than 350%. Reduce wear by more than 80%, extend the life of mechanical parts by more than 3 times, reduce downtime, reduce maintenance costs, extend overhaul period by more than double, save energy by 10%-30%, and increase equipment output power by 20%-40%. Only two tenths to one thousandth;

4. Application in high thermal conductivity plastics: The modified nano aluminum nitride powder can greatly improve the thermal conductivity of plastics. By adding 1% to the plastic in the experimental product, the thermal conductivity of the plastic can be increased from 0.3W to 3W, and the thermal conductivity is increased by more than 10 times. Currently mainly used in PVC plastics, polyurethane plastics, PA plastics, functional plastics, etc.;

5. Nano-aluminum nitride can be used to smelt non-ferrous metals and semiconductor materials gallium arsenide, evaporation boat, thermocouple protection tube, high temperature insulation, microwave dielectric materials, high temperature and corrosion resistant structural ceramics and transparent nitriding Aluminum microwave ceramic products.
