Lithium battery diaphragm finishing product:
High pureness nano alumina is put on the favorable and negative diaphragm of lithium battery as a ceramic finishing, which plays the duty of heat resistance, heat resistance and also insulation, so as to avoid the power battery from brief circuit because of heat as well as diaphragm melting.
Ingredients for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt as well as lithium manganate can improve thermal stability, cycle performance and also overcharge resistance, hinder the formation of oxygen as well as the decomposition of LiPF6, prevent direct call between LiCo02 and also electrolyte, reduce the loss of electrochemical particular capability, as well as boost the electrochemical certain capability of LiCoO2.
High pureness γ& gamma;-kind nano-alumina is a permeable material with an internal surface of numerous square meters per gram, high activity and strong adsorption ability. It is a generally used adsorbent, driver and also driver carrier in petroleum refining and petrochemical sector; it is a deacidizing agent for transformer oil and also wind turbine oil in sector, and also it is additionally made use of for chromatographic analysis; it is a neutral and also solid desiccant in the laboratory, its drying capacity is no much less than that of phosphorus pentoxide, as well as it can be regrowed as well as reused after heating below 175 ℃ for 6-8 hours.
Powder covering anti-caking:
In summer, nano-alumina can properly avoid powder covering caking. Nanometer aluminum trioxide made use of in powder finishes can enhance the fluffiness of powder finishes as well as have good anti-caking impact. It has good storability for powder coverings made use of in high temperature as well as high moisture atmosphere.
Layer, rubber, plastic wear-resistant as well as hardening representative:
Adding 5-20% nano-alumina, the finish can significantly improve the wear resistance and also scratch resistance of the finishing, which is 2-5 times greater than that of the traditional finish. After nano-alumina is contributed to the paint, a very great, consistent as well as difficult network structure can be based on the paint surface area, which secures the polymer paint layer from damage. the scratch resistance of nano-paint is 3 times greater than that of the initial paint. it is extensively utilized in vehicle paint and so on. The addition of nano-aluminum trioxide can significantly boost the hardness of the finishing, and regarding 20% can get to 6-7H. The openness of the coating is not affected.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big spherical dental filling. In order to boost the compatibility of material matrix and also fillers, enhance the thermal conductivity of matrix materials and not lower its mechanical properties, surface area therapy representatives such as combining representatives are frequently used to improve the thermal conductivity.
Nano alumina has high pureness, uniform bit dimension and good dispersion. When around 10% alumina is contributed to the sintered porcelains, the developing stress increases, which can minimize the number of pores, thus raise the thickness of the ceramic blank, boost the thickness and mechanical residential or commercial properties of the sintered alumina porcelains, and lower the sintering temperature better.
Nano alumina for metallurgy has tiny bit size, big details area and high task, adding 1-3% nano-alumina to stop matrix densification as well as grain dimension, enhance solidity, enhance electrical conductivity and also mechanical buildings, and improve melting factor as well as high temperature resistance.
Alumina fragments are consistent, have high sphericity, as well as are precision polishing powder, is an excellent product for metallographic sprucing up, yet likewise appropriate for stainless steel mirror polishing, titanium polishing, cast iron polishing, light weight aluminum mirror polishing, stone mirror polishing, paint polishing, material polishing, PCB circuit board polishing, glass sprucing up, optical glass, glasses lens sprucing up, material lens sprucing up, sapphire polishing, LED polishing, germanium polishing. Zinc polishing, quick polishing, good illumination, no scrapes.
