What is Alumina Nanoparticle used for
Lithium battery diaphragm layer product:
High pureness nano alumina is related to the favorable and adverse diaphragm of lithium battery as a ceramic layer, which plays the function of warmth resistance, heat resistance and insulation, so regarding prevent the power battery from brief circuit due to heat and diaphragm melting.
Ingredients for cathode materials of lithium batteries:
High purity nano-alumina doped with lithium cobalt and also lithium manganate can boost thermal security, cycle efficiency and overcharge resistance, prevent the development of oxygen as well as the decay of LiPF6, avoid direct get in touch with in between LiCo02 and also electrolyte, minimize the loss of electrochemical specific capability, and also improve the electrochemical specific ability of LiCoO2.
High pureness γ& gamma;-kind nano-alumina is a permeable substance with an inner area of hundreds of square meters per gram, high task as well as solid adsorption capability. It is a frequently used adsorbent, catalyst and also catalyst provider in petroleum refining and petrochemical industry; it is a deacidizing representative for transformer oil and generator oil in market, and also it is likewise utilized for chromatographic evaluation; it is a neutral and also strong desiccant busy, its drying out capacity is no much less than that of phosphorus pentoxide, and it can be regrowed and also recycled after home heating listed below 175 ℃ for 6-8 hrs.
Powder coating anti-caking:
In summer, nano-alumina can efficiently protect against powder coating caking. Nanometer aluminum trioxide used in powder coatings can improve the fluffiness of powder layers and have excellent anti-caking impact. It has excellent storability for powder finishings utilized in high temperature and high humidity environment.
Finish, rubber, plastic wear-resistant and hardening representative:
Including 5-20% nano-alumina, the covering can greatly enhance the wear resistance and also scrape resistance of the finishing, which is 2-5 times more than that of the conventional layer. After nano-alumina is contributed to the paint, an extremely fine, uniform and 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 utilized in auto paint and so on. The enhancement of nano-aluminum trioxide can substantially enhance the firmness of the finish, and also regarding 20% can reach 6-7H. The openness of the coating is not affected.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big spherical filling. In order to enhance the compatibility of material matrix as well as fillers, improve the thermal conductivity of matrix materials and not minimize its mechanical residential or commercial properties, surface treatment representatives such as combining agents are generally utilized to boost the thermal conductivity.
Nano alumina has high pureness, uniform bit size and also great dispersion. When around 10% alumina is contributed to the sintered porcelains, the creating pressure increases, which can reduce the variety of pores, thus boost the thickness of the ceramic blank, enhance the density and also mechanical homes of the sintered alumina ceramics, and minimize the sintering temperature better.
Nano alumina for metallurgy has small particle dimension, huge details surface as well as high activity, adding 1-3% nano-alumina to stop matrix densification as well as grain dimension, improve hardness, enhance electrical conductivity and also mechanical buildings, and boost melting point as well as high temperature resistance.
Alumina fragments are uniform, have high sphericity, and also are accuracy polishing powder, is a great material for metallographic sprucing up, but also suitable for stainless steel mirror polishing, titanium polishing, cast iron polishing, aluminum mirror sprucing up, stone mirror polishing, paint polishing, material polishing, PCB motherboard polishing, glass polishing, optical glass, glasses lens sprucing up, resin lens polishing, sapphire sprucing up, LED sprucing up, germanium polishing. Zinc sprucing up, fast sprucing up, great brightness, no scrapes.
