What is Alumina Nanoparticle used for
Lithium battery diaphragm covering product:
High pureness nano alumina is put on the favorable as well as negative diaphragm of lithium battery as a ceramic covering, which plays the duty of heat resistance, heat resistance as well as insulation, so regarding protect against the power battery from brief circuit as a result of high temperature and also diaphragm melting.
Ingredients for cathode materials of lithium batteries:
High purity nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal security, cycle efficiency and also 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, reduce the loss of electrochemical certain capacity, as well as enhance the electrochemical specific ability of LiCoO2.
High pureness γ& gamma;-kind nano-alumina is a permeable compound with an interior surface area of thousands of square meters per gram, high task and also solid adsorption capability. It is a typically utilized adsorbent, stimulant and catalyst provider in petroleum refining as well as petrochemical sector; it is a deacidizing representative for transformer oil and wind turbine oil in sector, and it is likewise used for chromatographic evaluation; it is a neutral and solid desiccant in the laboratory, its drying ability is no much less than that of phosphorus pentoxide, as well as it can be restored and recycled after heating below 175 ℃ for 6-8 hours.
Powder finish anti-caking:
In summertime, nano-alumina can efficiently protect against powder coating caking. Nanometer aluminum trioxide made use of in powder finishes can enhance the fluffiness of powder layers and have great anti-caking result. It has excellent storability for powder layers made use of in heat and high humidity atmosphere.
Finish, rubber, plastic wear-resistant and hardening representative:
Including 5-20% nano-alumina, the finishing can greatly improve the wear resistance as well as scrape resistance of the finish, which is 2-5 times more than that of the traditional coating. After nano-alumina is included in the paint, a very great, uniform as well as difficult network framework can be based on the paint surface area, which shields the polymer paint layer from damage. the scrape resistance of nano-paint is 3 times more than that of the initial paint. it is widely made use of in automobile paint and so on. The enhancement of nano-aluminum trioxide can substantially boost the hardness of the finishing, and regarding 20% can get to 6-7H. The openness of the coating is not impacted.
Plastic, rubber, glue, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large round filling. In order to improve the compatibility of material matrix and also fillers, improve the thermal conductivity of matrix materials and not reduce its mechanical residential or commercial properties, surface treatment agents such as coupling agents are typically used to improve the thermal conductivity.
Nano alumina has high pureness, consistent particle dimension and good diffusion. When around 10% alumina is included in the sintered ceramics, the creating stress boosts, which can reduce the variety of pores, hence raise the thickness of the ceramic space, boost the density and also mechanical homes of the sintered alumina porcelains, and also decrease the sintering temperature level better.
Nano alumina for metallurgy has small fragment dimension, large details surface area and also high activity, adding 1-3% nano-alumina to prevent matrix densification and also grain size, improve solidity, boost electric conductivity and also mechanical residential properties, as well as improve melting factor as well as high temperature resistance.
Alumina particles are uniform, have high sphericity, and also are precision polishing powder, is a great product for metallographic polishing, yet additionally ideal for stainless steel mirror polishing, titanium polishing, cast iron polishing, aluminum mirror polishing, stone mirror polishing, paint polishing, resin sprucing up, PCB circuit card sprucing up, glass polishing, optical glass, glasses lens sprucing up, resin lens sprucing up, sapphire sprucing up, LED polishing, germanium polishing. Zinc polishing, rapid polishing, excellent illumination, no scratches.
