What is Alumina Nanoparticle used for
Lithium battery diaphragm covering product:
High pureness nano alumina is applied to the positive as well as adverse diaphragm of lithium battery as a ceramic layer, which plays the role of warmth resistance, heat resistance as well as insulation, so regarding avoid the power battery from short circuit because of heat and diaphragm melting.
Ingredients for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt and also lithium manganate can improve thermal stability, cycle efficiency and also overcharge resistance, hinder the formation of oxygen as well as the disintegration of LiPF6, prevent direct contact between LiCo02 as well as electrolyte, lower the loss of electrochemical particular ability, and also boost the electrochemical details capability of LiCoO2.
High pureness γ& gamma;-type nano-alumina is a permeable compound with an internal surface area of hundreds of square meters per gram, high activity and strong adsorption capacity. It is a typically utilized adsorbent, catalyst and catalyst provider in oil refining and petrochemical industry; it is a deacidizing agent for transformer oil and also generator oil in market, as well as it is likewise utilized for chromatographic analysis; it is a neutral and strong desiccant busy, its drying out ability is no less than that of phosphorus pentoxide, and also it can be regenerated as well as reused after home heating below 175 ℃ for 6-8 hrs.
Powder finish anti-caking:
In summertime, nano-alumina can properly avoid powder covering caking. Nanometer aluminum trioxide used in powder coverings can enhance the fluffiness of powder layers as well as have great anti-caking effect. It has good storability for powder coverings made use of in heat as well as high moisture setting.
Coating, rubber, plastic wear-resistant as well as hardening representative:
Adding 5-20% nano-alumina, the covering can greatly improve the wear resistance and also scratch resistance of the finish, which is 2-5 times more than that of the typical finishing. After nano-alumina is added to the paint, an extremely great, consistent as well as difficult network framework can be based on the paint surface area, which secures the polymer paint layer from damage. the scrape resistance of nano-paint is 3 times higher than that of the original paint. it is extensively made use of in car paint and more. The enhancement of nano-aluminum trioxide can significantly enhance the firmness of the layer, and also about 20% can reach 6-7H. The openness of the coating is not affected.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big round dental filling. In order to improve the compatibility of resin matrix and fillers, enhance the thermal conductivity of matrix materials as well as not reduce its mechanical properties, surface treatment representatives such as coupling agents are generally used to improve the thermal conductivity.
Nano alumina has high pureness, consistent fragment size and excellent dispersion. When around 10% alumina is contributed to the sintered ceramics, the creating pressure increases, which can reduce the number of pores, thus boost the density of the ceramic blank, enhance the density and mechanical residential or commercial properties of the sintered alumina porcelains, and also reduce the sintering temperature more effectively.
Nano alumina for metallurgy has tiny bit dimension, big specific surface area and high activity, including 1-3% nano-alumina to prevent matrix densification and grain size, enhance solidity, enhance electrical conductivity as well as mechanical residential properties, and also boost melting factor and also high temperature resistance.
Alumina fragments are uniform, have high sphericity, and are precision polishing powder, is a good material for metallographic polishing, yet additionally appropriate for stainless-steel mirror sprucing up, titanium sprucing up, cast iron sprucing up, aluminum mirror polishing, stone mirror sprucing up, paint sprucing up, material polishing, PCB motherboard polishing, glass polishing, optical glass, glasses lens sprucing up, resin lens sprucing up, sapphire sprucing up, LED polishing, germanium sprucing up. Zinc sprucing up, rapid sprucing up, excellent brightness, no scrapes.
