Lithium battery diaphragm finishing product:
High pureness nano alumina is put on the positive as well as adverse diaphragm of lithium battery as a ceramic finishing, which plays the duty of warmth resistance, heat resistance and insulation, so regarding stop the power battery from brief circuit because of high temperature and also diaphragm melting.
Ingredients for cathode materials of lithium batteries:
High purity nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal security, cycle performance and also overcharge resistance, hinder the formation of oxygen as well as the disintegration of LiPF6, avoid direct get in touch with in between LiCo02 and also electrolyte, minimize the loss of electrochemical specific capacity, and boost the electrochemical specific ability of LiCoO2.
High pureness γ-type nano-alumina is a porous material with an inner area of thousands of square meters per gram, high activity and also strong adsorption capability. It is a typically made use of adsorbent, catalyst as well as driver service provider in petroleum refining as well as petrochemical sector; it is a deacidizing representative for transformer oil and also wind turbine oil in industry, and it is also utilized for chromatographic evaluation; it is a neutral as well as solid desiccant busy, its drying capability is no much less than that of phosphorus pentoxide, and it can be restored as well as reused after home heating listed below 175 ℃ for 6-8 hrs.
Powder layer anti-caking:
In summer, nano-alumina can successfully prevent powder finishing caking. Nanometer light weight aluminum trioxide made use of in powder coverings can enhance the fluffiness of powder coverings and have good anti-caking impact. It has excellent storability for powder coverings made use of in heat and also high moisture setting.
Covering, rubber, plastic wear-resistant and hardening agent:
Adding 5-20% nano-alumina, the layer can greatly enhance the wear resistance as well as scrape resistance of the finish, which is 2-5 times greater than that of the conventional covering. After nano-alumina is added to the paint, a very fine, uniform and tough network structure can be based 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 initial paint. it is widely used in car paint and so on. The addition of nano-aluminum trioxide can dramatically improve the hardness of the layer, and about 20% can get to 6-7H. The transparency of the finishing is not influenced.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large round dental filling. In order to boost the compatibility of resin matrix and also fillers, improve the thermal conductivity of matrix materials as well as not lower its mechanical residential properties, surface treatment representatives such as coupling agents are frequently made use of to improve the thermal conductivity.
Nano alumina has high purity, consistent bit dimension as well as good dispersion. When around 10% alumina is included in the sintered porcelains, the forming pressure boosts, which can reduce the variety of pores, hence increase the thickness of the ceramic space, enhance the thickness and mechanical homes of the sintered alumina ceramics, as well as decrease the sintering temperature level better.
Nano alumina for metallurgy has tiny particle size, big certain surface and high activity, including 1-3% nano-alumina to avoid matrix densification and grain size, enhance solidity, improve electrical conductivity as well as mechanical properties, and also boost melting point as well as high temperature resistance.
Alumina fragments are uniform, have high sphericity, and are accuracy brightening powder, is a good material for metallographic polishing, however additionally suitable for stainless-steel mirror polishing, titanium polishing, cast iron sprucing up, aluminum mirror sprucing up, rock mirror sprucing up, paint sprucing up, resin polishing, PCB circuit board sprucing up, glass sprucing up, optical glass, glasses lens sprucing up, material lens sprucing up, sapphire polishing, LED sprucing up, germanium polishing. Zinc sprucing up, fast polishing, excellent brightness, no scratches.
