What is Alumina Nanoparticle used for
Lithium battery diaphragm layer product:
High purity nano alumina is related to the favorable and unfavorable diaphragm of lithium battery as a ceramic coating, which plays the function of heat resistance, heat resistance and insulation, so as to prevent the power battery from brief circuit because of heat and diaphragm melting.
Additives for cathode materials of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and also lithium manganate can improve thermal security, cycle performance as well as overcharge resistance, inhibit the formation of oxygen and the decomposition of LiPF6, stay clear of straight call in between LiCo02 and electrolyte, reduce the loss of electrochemical certain capacity, and also boost the electrochemical certain ability of LiCoO2.
Catalyst service provider:
High pureness γ& gamma;-type nano-alumina is a porous substance with an interior surface of numerous square meters per gram, high task and strong adsorption ability. It is a frequently made use of adsorbent, stimulant and also driver service provider in oil refining as well as petrochemical market; it is a deacidizing representative for transformer oil and also turbine oil in sector, and it is also utilized for chromatographic evaluation; it is a neutral and also strong desiccant in the laboratory, its drying capacity is no much less than that of phosphorus pentoxide, as well as it can be regenerated and recycled after home heating below 175 ℃ for 6-8 hours.
Powder covering anti-caking:
In summer season, nano-alumina can successfully avoid powder finishing caking. Nanometer aluminum trioxide used in powder coatings can enhance the fluffiness of powder coverings and have good anti-caking result. It has great storability for powder finishings used in heat and high humidity environment.
Layer, rubber, plastic wear-resistant as well as hardening representative:
Adding 5-20% nano-alumina, the finish can greatly boost the wear resistance and scrape resistance of the layer, which is 2-5 times more than that of the conventional covering. After nano-alumina is contributed to the paint, a really great, uniform and also tough network structure can be based on the paint surface area, which protects the polymer paint layer from damage. the scratch resistance of nano-paint is 3 times higher than that of the original paint. it is extensively utilized in vehicle paint and so on. The addition of nano-aluminum trioxide can significantly enhance the firmness of the finish, as well as concerning 20% can reach 6-7H. The transparency of the layer 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 enhance the compatibility of resin matrix and fillers, enhance the thermal conductivity of matrix products and not lower its mechanical residential properties, surface therapy agents such as coupling agents are typically utilized to boost the thermal conductivity.
Nano alumina has high pureness, consistent bit dimension and also great diffusion. When around 10% alumina is included in the sintered ceramics, the forming stress rises, which can reduce the number of pores, hence enhance the thickness of the ceramic blank, improve the thickness as well as mechanical residential properties of the sintered alumina ceramics, and lower the sintering temperature better.
Nano alumina for metallurgy has tiny particle size, huge particular surface and high activity, including 1-3% nano-alumina to stop matrix densification and grain size, improve firmness, boost electric conductivity and also mechanical buildings, as well as enhance melting point as well as high temperature resistance.
Alumina bits are consistent, have high sphericity, as well as are accuracy polishing powder, is a great product for metallographic polishing, yet likewise suitable for stainless steel mirror polishing, titanium sprucing up, cast iron sprucing up, light weight aluminum mirror polishing, rock mirror sprucing up, paint sprucing up, resin polishing, PCB motherboard polishing, glass polishing, optical glass, glasses lens polishing, resin lens sprucing up, sapphire polishing, LED polishing, germanium polishing. Zinc sprucing up, quick polishing, good brightness, no scratches.
