Nano-alumina (model -) has uniform particle size distribution, high resistivity and good insulation properties. It is widely used in plastics, rubber, ceramic coatings, polyimide films (tape), polyester films ( Main application fields of insulation products such as belts), soft composite materials (D, DD, etc.) (belts), polyester fiber cloth (belts):
.Insulating coatings, coatings, coatings:
Adding nano-alumina (model-) to the coating can improve the density and dielectric breakdown strength of the coating and provide the best overall insulation performance. At the same time, the high temperature resistance is improved
. Thermal conductive insulation composite material:
Adding nano-alumina (model-) to the resin plastic rubber can significantly improve the insulation performance and thermal conductivity. The insulation performance can be increased by more than 100% at the same time. Thermal mesh chain.
.Insulator material of high-voltage lead-in rod:
The high-voltage lead-in rod made by adding nano-alumina (model-) has excellent acid corrosion resistance, electrical performance and extremely high mechanical strength, and can be widely used in chemical industry , metallurgy, electric power, electronics and other occasions with harsh operating environments or special requirements.
. Lithium battery for electric vehicle laptops and other batteries:
The positive and negative electrodes are sealed with a nano-alumina (model-) electrical insulator to improve safety performance.
) When the nanometer content is not greater than %, the viscosity of the glue decreases at a rate not faster than that of pure polyamic acid resin. Therefore, the presence of nanoprecursors has little effect on the storage stability of the glue.
) The apparent decomposition temperature of the composite film first increases with the increase of nanometer content, reaches a maximum value at about %, and then decreases, which is about ℃ higher than that of the pure film.
) As the nanometer content increases, the tensile strength of the film first increases at %, reaches the maximum value, and then decreases. Compared with the pure film, the glue solution has little effect on the tensile strength of the composite film.
) Under normal conditions, when the nanometer content is %, the volume resistivity of the composite film reaches the maximum value, which is an order of magnitude higher than that of pure nanoparticles. Therefore, adding a certain amount can improve the electrical insulation of the composite film, especially the high temperature volume resistivity.
Usage: It is recommended that the grinding effect will be better after stirring
