Lithium battery diaphragm finishing material:
High pureness nano alumina is put on the positive as well as adverse diaphragm of lithium battery as a ceramic covering, which plays the role of heat resistance, high temperature resistance and insulation, so as to prevent the power battery from short circuit as a result of heat and also diaphragm melting.
Ingredients for cathode materials of lithium batteries:
High purity nano-alumina doped with lithium cobalt and also lithium manganate can enhance thermal stability, cycle performance as well as overcharge resistance, hinder the formation of oxygen and the decay of LiPF6, prevent straight call in between LiCo02 and also electrolyte, decrease the loss of electrochemical details capability, and enhance the electrochemical certain ability of LiCoO2.
High purity γ-type nano-alumina is a permeable compound with an interior surface of numerous square meters per gram, high activity and also strong adsorption ability. It is a frequently used adsorbent, catalyst and driver provider in oil refining as well as petrochemical industry; it is a deacidizing agent for transformer oil as well as turbine oil in sector, and it is additionally made use of 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, as well as it can be restored as well as recycled after heating below 175 ℃ for 6-8 hrs.
Powder finishing anti-caking:
In summertime, nano-alumina can properly protect against powder layer caking. Nanometer light weight aluminum trioxide utilized in powder finishes can boost the fluffiness of powder coverings and have great anti-caking impact. It has excellent storability for powder finishes utilized in high temperature and high moisture atmosphere.
Finish, rubber, plastic wear-resistant and also hardening representative:
Adding 5-20% nano-alumina, the finish can significantly boost the wear resistance and also scrape resistance of the covering, which is 2-5 times more than that of the traditional finishing. After nano-alumina is added to the paint, a really fine, consistent as well as difficult network framework can be formed on the paint surface area, which protects the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times higher than that of the original paint. it is commonly utilized in automobile paint and so forth. The enhancement of nano-aluminum trioxide can significantly enhance the solidity of the covering, as well as concerning 20% can reach 6-7H. The openness of the coating is not affected.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, huge round filling. In order to improve the compatibility of resin matrix and fillers, enhance the thermal conductivity of matrix materials and also not lower its mechanical properties, surface treatment representatives such as combining agents are frequently used to improve the thermal conductivity.
Nano alumina has high purity, consistent bit dimension and great diffusion. When about 10% alumina is included in the sintered ceramics, the developing pressure boosts, which can lower the number of pores, hence boost the thickness of the ceramic space, improve the thickness as well as mechanical homes of the sintered alumina porcelains, and reduce the sintering temperature more effectively.
Nano alumina for metallurgy has tiny bit size, large particular surface area and high task, including 1-3% nano-alumina to avoid matrix densification and grain dimension, boost solidity, enhance electric conductivity and also mechanical residential or commercial properties, and also improve melting factor and also heat resistance.
Alumina fragments are uniform, have high sphericity, and also are accuracy polishing powder, is a great material for metallographic polishing, but also appropriate for stainless steel mirror sprucing up, titanium sprucing up, cast iron polishing, aluminum mirror sprucing up, rock mirror polishing, paint sprucing up, material polishing, PCB motherboard polishing, glass polishing, optical glass, glasses lens polishing, resin lens sprucing up, sapphire sprucing up, LED polishing, germanium polishing. Zinc sprucing up, rapid sprucing up, great brightness, no scrapes.
