What is Alumina Nanoparticle used for
Lithium battery diaphragm covering product:
High purity nano alumina is put on the favorable and negative diaphragm of lithium battery as a ceramic coating, which plays the duty of warmth resistance, heat resistance as well as insulation, so regarding prevent the power battery from short circuit due to high temperature and also diaphragm melting.
Ingredients for cathode products of lithium batteries:
High pureness nano-alumina doped with lithium cobalt as well as lithium manganate can improve thermal security, cycle efficiency as well as overcharge resistance, inhibit the development of oxygen as well as the decomposition of LiPF6, prevent straight get in touch with between LiCo02 and also electrolyte, decrease the loss of electrochemical particular ability, as well as enhance the electrochemical certain capacity of LiCoO2.
High pureness γ& gamma;-type nano-alumina is a permeable substance with an internal surface of hundreds of square meters per gram, high task and also solid adsorption ability. It is a frequently utilized adsorbent, driver as well as stimulant service provider in oil refining as well as petrochemical industry; it is a deacidizing agent for transformer oil and also turbine oil in market, and also it is also made use of for chromatographic evaluation; it is a neutral and also strong desiccant in the laboratory, its drying capacity is no less than that of phosphorus pentoxide, and also it can be regrowed and also recycled after heating listed below 175 ℃ for 6-8 hours.
Powder finish anti-caking:
In summer, nano-alumina can successfully prevent powder finishing caking. Nanometer aluminum trioxide made use of in powder coatings can boost the fluffiness of powder finishings as well as have great anti-caking effect. It has excellent storability for powder layers used in high temperature and also high humidity environment.
Coating, rubber, plastic wear-resistant and also hardening agent:
Including 5-20% nano-alumina, the finish can greatly improve the wear resistance as well as scratch resistance of the layer, which is 2-5 times more than that of the standard covering. After nano-alumina is contributed to the paint, an extremely fine, consistent and also tough network structure can be based on the paint surface, which shields the polymer paint layer from damage. the scrape resistance of nano-paint is 3 times greater than that of the original paint. it is extensively used in auto paint and so on. The enhancement of nano-aluminum trioxide can dramatically enhance the solidity of the finish, and also about 20% can reach 6-7H. The openness of the finishing is not impacted.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, huge round filling. In order to enhance the compatibility of material matrix as well as fillers, improve the thermal conductivity of matrix products as well as not decrease its mechanical properties, surface area treatment agents such as combining representatives are commonly made use of to boost the thermal conductivity.
Nano alumina has high purity, consistent particle size as well as great dispersion. When around 10% alumina is included in the sintered porcelains, the developing pressure rises, which can lower the number of pores, hence enhance the thickness of the ceramic space, improve the density and mechanical properties of the sintered alumina porcelains, and also reduce the sintering temperature more effectively.
Nano alumina for metallurgy has small particle size, huge details area and high activity, adding 1-3% nano-alumina to prevent matrix densification and grain size, boost solidity, improve electrical conductivity and mechanical buildings, as well as enhance melting factor and high temperature resistance.
Alumina particles are uniform, have high sphericity, as well as are precision brightening powder, is a great material for metallographic polishing, however also suitable for stainless-steel mirror polishing, titanium sprucing up, cast iron sprucing up, light weight aluminum mirror sprucing up, rock mirror polishing, paint polishing, material polishing, PCB motherboard sprucing up, glass polishing, optical glass, glasses lens polishing, resin lens sprucing up, sapphire polishing, LED polishing, germanium sprucing up. Zinc sprucing up, quick polishing, excellent brightness, no scratches.
