Usage performance:
, scratch resistance: coating After adding nano-alumina to the paint, a very fine, uniform and very hard network structure can be formed on the surface of the paint to protect the underlying polymer paint layer from damage. The anti-scratch performance of nano-paint is better than that of the original paint. It is widely used in automobile paints, etc. Wear resistance: Nano-alumina has excellent wear resistance and is widely used in the field of coatings and paints. The coating made by adding % nano-alumina can greatly improve the wear resistance of the coating, which is ~ times higher than that of traditional coatings. Widely used in furniture paint, etc.
, resistance:
The resistance performance test of nano-paint is tested on various automobile parts under laboratory conditions.
Since the year, tests have been carried out on test vehicles, such as car wash tests, where nano-painted cars are brushed with car wash
containing a certain amount of quartz sand. In the test, washing the car once is equivalent to washing the car ~
times in real life. After such a car wash test, the remaining gloss of ordinary paint is only %, while the remaining gloss of nano paint is still above %, and there is basically no scratch. Insulation:
Nano-alumina has high resistivity and good insulation properties, and is widely used in plastics, rubber, ceramics, coatings, polyimide films, polyester films, polyester fiber cloth and other insulation products, The density and dielectric breakdown strength of the coating can be improved, and the insulation performance can be improved by more than 100%. Thermal conductivity: The coating added with nano-alumina has good thermal conductivity and insulation properties, and is widely used Used in various electronic materials
to enhance toughness: Nano-alumina has a good effect on toughening and strengthening the coating. When the addition amount is %, the coating has the best toughening effect
Good, and at the same time, the mechanical properties have reached the highest level. The shear strength at ℃ is increased by %, the tensile strength is increased by %, the elongation at break is increased by %, and the bending strength is increased by %. Transparency: Nano-alumina particles The diameter is between nanometers, and its size is smaller than the wavelength of light. Therefore, it is an invisible protective layer that will not hinder the appearance of the paint color, nor will it affect the transparency and gloss of the coating.
, Adding amount: The maximum adding amount of this nano-alumina is % and it can maintain the transparency of more than %. The specific usage amount is based on the manufacturer's requirements for product wear resistance and comprehensive cost accounting. Users can adjust according to different systems. , determine the optimal addition amount through experiments.
