Lithium battery diaphragm finish product:
High purity nano alumina is put on the favorable and also negative diaphragm of lithium battery as a ceramic finish, which plays the function of heat resistance, heat resistance and insulation, so regarding stop the power battery from short circuit due to high temperature and diaphragm melting.
Ingredients for cathode products of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and lithium manganate can boost thermal security, cycle efficiency as well as overcharge resistance, hinder the formation of oxygen and also the disintegration of LiPF6, stay clear of straight call between LiCo02 as well as electrolyte, minimize the loss of electrochemical certain capability, and also boost the electrochemical certain capacity of LiCoO2.
Catalyst service provider:
High purity γ& gamma;-kind nano-alumina is a porous compound with an internal area of hundreds of square meters per gram, high activity and strong adsorption ability. It is a frequently made use of adsorbent, driver as well as stimulant provider in petroleum refining as well as petrochemical sector; it is a deacidizing representative for transformer oil as well as wind turbine oil in industry, and also it is additionally utilized for chromatographic analysis; it is a neutral as well as solid desiccant in the laboratory, its drying out capability is no less than that of phosphorus pentoxide, and also it can be restored and also recycled after heating listed below 175 ℃ for 6-8 hours.
Powder coating anti-caking:
In summer, nano-alumina can efficiently protect against powder finish caking. Nanometer light weight aluminum trioxide used in powder finishes can improve the fluffiness of powder finishings as well as have excellent anti-caking effect. It has excellent storability for powder layers used in heat as well as high humidity setting.
Coating, rubber, plastic wear-resistant and hardening representative:
Adding 5-20% nano-alumina, the layer can greatly enhance the wear resistance and scrape resistance of the finishing, which is 2-5 times higher than that of the conventional coating. After nano-alumina is contributed to the paint, a really great, consistent and difficult network framework can be based on the paint surface, which shields the polymer paint layer from damages. the scratch resistance of nano-paint is 3 times more than that of the initial paint. it is extensively made use of in vehicle paint and so on. The enhancement of nano-aluminum trioxide can significantly enhance the hardness of the coating, and concerning 20% can reach 6-7H. The transparency of the coating is not influenced.
Plastic, rubber, glue, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large round dental filling. In order to enhance the compatibility of material matrix and also fillers, boost the thermal conductivity of matrix materials as well as not lower its mechanical residential properties, surface therapy agents such as combining representatives are generally made use of to enhance the thermal conductivity.
Nano alumina has high purity, uniform fragment size as well as great dispersion. When about 10% alumina is contributed to the sintered ceramics, the creating pressure boosts, which can minimize the number of pores, hence boost the density of the ceramic space, boost the density and also mechanical homes of the sintered alumina porcelains, and decrease the sintering temperature better.
Nano alumina for metallurgy has small particle size, big certain area as well as high task, including 1-3% nano-alumina to stop matrix densification as well as grain dimension, boost firmness, improve electrical conductivity and mechanical properties, and also boost melting point and high temperature resistance.
Alumina bits are consistent, have high sphericity, as well as are precision polishing powder, is a good material for metallographic polishing, however additionally ideal for stainless-steel mirror polishing, titanium sprucing up, cast iron sprucing up, aluminum mirror polishing, stone mirror polishing, paint polishing, resin polishing, PCB circuit card sprucing up, glass sprucing up, optical glass, glasses lens polishing, material lens sprucing up, sapphire sprucing up, LED polishing, germanium polishing. Zinc polishing, fast sprucing up, good brightness, no scratches.
