Special nano-alumina for thermal conductivity
Thermal conductivity of nano-alumina/,
Basic information:
:
Nano-alumina has high hardness, good dimensional stability, high thermal conductivity, and can It is widely used in the reinforcement and toughening of various plastic, rubber, ink, ceramic refractory materials and other products, and the thermal conductivity of various rubbers, especially to improve the density, smoothness, hot and cold fatigue fracture toughness, creep resistance, creep resistance and wear resistance of polymer material products of ceramics. The performance is particularly remarkable. Since nano-alumina is also a far-infrared emitting material with excellent performance, it is used in chemical fiber products and high-pressure sodium lamps as far-infrared emitting and thermal insulation materials. In addition, nano-alumina has high resistivity and good insulation properties, and can be used in major accessories of laser crystals and integrated circuit substrates.
Under the same filling amount, the thermal conductive rubber filled with nano alumina has better thermal conductivity and physical and mechanical properties than the thermal conductive rubber filled with micron alumina. At the appropriate ratio, nano alumina and micron alumina are mixed and filled. Thermal conductive rubber has better thermal conductivity than rubber simply filled with micron particles
When the weight fraction of the target mixed filler is ~, the system viscosity is the smallest, the fluidity and the thermal conductivity of silicone rubber are the best.
Adding an appropriate amount of nano-alumina to the mixture can improve its thermal conductivity. Adding graphite appropriately to the mixture will increase the thermal conductivity even more. Appropriately extend the melting and blending time, and the better the dispersion will be. The higher the thermal conductivity.
Nano-aluminum oxide is used as a thermally conductive filler for rubber plastics. Compared with metal thermally conductive fillers, its advantage is that nano-aluminum oxide can not only improve the thermal conductivity, but also has good insulation effect. At the same time, the mechanical properties of the material have also been improved. improve.
Nano-alumina is used for thermal conduction in silica gel. It not only has good thermal conductivity, does not affect the viscosity, but also has good transparency.
