What is Alumina Nanoparticle used for
Lithium battery diaphragm coating material:
High purity nano alumina is put on the positive as well as unfavorable diaphragm of lithium battery as a ceramic finishing, which plays the function of warmth resistance, high temperature resistance as well as insulation, so regarding protect against the power battery from short circuit as a result of high temperature and diaphragm melting.
Additives for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt and also lithium manganate can boost thermal stability, cycle efficiency as well as overcharge resistance, hinder the development of oxygen and the decomposition of LiPF6, prevent straight contact between LiCo02 as well as electrolyte, lower the loss of electrochemical details ability, and enhance the electrochemical certain capability of LiCoO2.
Catalyst service provider:
High pureness γ& gamma;-type nano-alumina is a permeable material with an inner surface of hundreds of square meters per gram, high task and strong adsorption ability. It is a typically used adsorbent, driver as well as catalyst service provider in petroleum refining and petrochemical market; it is a deacidizing representative for transformer oil and turbine oil in sector, as well as it is additionally utilized for chromatographic analysis; it is a neutral and also strong desiccant in the laboratory, its drying out capacity is no much less than that of phosphorus pentoxide, and it can be regrowed as well as recycled after home heating below 175 ℃ for 6-8 hours.
Powder finishing anti-caking:
In summer season, nano-alumina can properly avoid powder coating caking. Nanometer aluminum trioxide utilized in powder coverings can improve the fluffiness of powder layers as well as have great anti-caking impact. It has excellent storability for powder coverings used in high temperature as well as high moisture environment.
Covering, rubber, plastic wear-resistant as well as hardening representative:
Adding 5-20% nano-alumina, the finishing can substantially improve the wear resistance and scratch resistance of the coating, which is 2-5 times more than that of the traditional layer. After nano-alumina is added to the paint, an extremely great, consistent and also tough network framework can be formed on the paint surface, which protects the polymer paint layer from damages. the scratch resistance of nano-paint is 3 times higher than that of the initial paint. it is widely made use of in car paint and more. The enhancement of nano-aluminum trioxide can dramatically improve the solidity of the coating, and about 20% can get to 6-7H. The openness of the covering is not influenced.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big spherical filling. In order to boost the compatibility of resin matrix as well as fillers, improve the thermal conductivity of matrix products and also not reduce its mechanical residential properties, surface therapy agents such as combining agents are generally used to improve the thermal conductivity.
Nano alumina has high purity, consistent particle dimension and also great dispersion. When around 10% alumina is included in the sintered ceramics, the creating pressure rises, which can lower the variety of pores, hence increase the density of the ceramic space, improve the density as well as mechanical residential or commercial properties of the sintered alumina ceramics, as well as lower the sintering temperature level better.
Nano alumina for metallurgy has small particle size, huge certain surface area as well as high activity, adding 1-3% nano-alumina to prevent matrix densification as well as grain size, enhance firmness, enhance electric conductivity and mechanical buildings, as well as improve melting point as well as heat resistance.
Alumina bits are uniform, have high sphericity, and also are accuracy polishing powder, is a good product for metallographic sprucing up, but also suitable for stainless-steel mirror sprucing up, titanium polishing, cast iron sprucing up, aluminum mirror sprucing up, stone mirror sprucing up, paint polishing, resin sprucing up, PCB motherboard sprucing up, glass sprucing up, optical glass, glasses lens polishing, resin lens polishing, sapphire sprucing up, LED sprucing up, germanium sprucing up. Zinc polishing, rapid polishing, excellent brightness, no scratches.
