What is Alumina Nanoparticle used for
Lithium battery diaphragm covering product:
High purity nano alumina is applied to the positive and adverse diaphragm of lithium battery as a ceramic coating, which plays the duty of warmth resistance, high temperature resistance and insulation, so as to avoid the power battery from brief circuit because of heat and diaphragm melting.
Ingredients for cathode materials of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and lithium manganate can boost thermal security, cycle performance as well as overcharge resistance, prevent the development of oxygen and also the decay of LiPF6, avoid direct contact in between LiCo02 and also electrolyte, lower the loss of electrochemical specific ability, and also improve the electrochemical details capacity of LiCoO2.
High pureness γ& gamma;-kind nano-alumina is a permeable compound with an internal surface of hundreds of square meters per gram, high task as well as solid adsorption capability. It is a generally utilized adsorbent, stimulant and also driver service provider in oil refining and also petrochemical sector; it is a deacidizing agent for transformer oil and wind turbine oil in market, as well as it is likewise made use of for chromatographic analysis; it is a neutral as well as solid desiccant in the laboratory, its drying capability is no less than that of phosphorus pentoxide, and it can be restored and also recycled after home heating listed below 175 ℃ for 6-8 hrs.
Powder finishing anti-caking:
In summertime, nano-alumina can successfully avoid powder layer caking. Nanometer light weight aluminum trioxide used in powder finishings can improve the fluffiness of powder finishings as well as have excellent anti-caking result. It has great storability for powder finishings used in high temperature as well as high humidity atmosphere.
Finish, rubber, plastic wear-resistant and also hardening representative:
Including 5-20% nano-alumina, the finish can greatly improve the wear resistance and scratch resistance of the finish, which is 2-5 times more than that of the standard finishing. After nano-alumina is contributed to the paint, an extremely great, uniform and hard network structure can be formed on the paint surface area, which secures the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times more than that of the initial paint. it is extensively utilized in auto paint and more. The addition of nano-aluminum trioxide can substantially improve the firmness of the coating, as well as regarding 20% can reach 6-7H. The openness of the coating is not impacted.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, huge round dental filling. In order to enhance the compatibility of material matrix as well as fillers, enhance the thermal conductivity of matrix materials as well as not reduce its mechanical residential properties, surface area treatment agents such as coupling agents are frequently utilized to enhance the thermal conductivity.
Nano alumina has high pureness, consistent particle size as well as good dispersion. When about 10% alumina is added to the sintered porcelains, the developing pressure rises, which can decrease the number of pores, thus boost the thickness of the ceramic blank, enhance the density as well as mechanical properties of the sintered alumina porcelains, and also lower the sintering temperature more effectively.
Nano alumina for metallurgy has little bit size, large particular area and high activity, adding 1-3% nano-alumina to avoid matrix densification and grain size, boost firmness, boost electric conductivity and mechanical buildings, and improve melting point and high temperature resistance.
Alumina fragments are consistent, have high sphericity, and also are accuracy brightening powder, is a great material for metallographic sprucing up, yet additionally ideal for stainless steel mirror sprucing up, titanium sprucing up, cast iron polishing, light weight aluminum mirror sprucing up, stone mirror sprucing up, paint sprucing up, material polishing, PCB circuit card polishing, glass polishing, optical glass, glasses lens sprucing up, material lens sprucing up, sapphire sprucing up, LED sprucing up, germanium polishing. Zinc polishing, fast sprucing up, great brightness, no scrapes.
