What is Alumina Nanoparticle used for
Lithium battery diaphragm layer material:
High pureness nano alumina is put on the favorable and adverse diaphragm of lithium battery as a ceramic layer, which plays the duty of heat resistance, high temperature resistance as well as insulation, so regarding protect against the power battery from brief circuit because of heat and also diaphragm melting.
Ingredients for cathode products of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and also lithium manganate can improve thermal security, cycle performance and overcharge resistance, prevent the development of oxygen and also the decay of LiPF6, avoid straight contact in between LiCo02 and also electrolyte, decrease the loss of electrochemical details capacity, and enhance the electrochemical certain capability of LiCoO2.
Catalyst service provider:
High purity γ& gamma;-type nano-alumina is a porous substance with an interior area of numerous square meters per gram, high activity and also strong adsorption capacity. It is a generally used adsorbent, stimulant and catalyst carrier in petroleum refining and also petrochemical industry; it is a deacidizing agent for transformer oil as well as turbine oil in industry, as well as it is likewise made use of for chromatographic evaluation; it is a neutral as well as strong desiccant in the laboratory, its drying capacity is no less than that of phosphorus pentoxide, and also it can be regenerated and reused after heating listed below 175 ℃ for 6-8 hours.
Powder layer anti-caking:
In summertime, nano-alumina can properly prevent powder coating caking. Nanometer aluminum trioxide utilized in powder coatings can improve the fluffiness of powder coverings as well as have good anti-caking result. It has great storability for powder coverings utilized in high temperature and also high moisture atmosphere.
Covering, rubber, plastic wear-resistant and also hardening agent:
Adding 5-20% nano-alumina, the finishing can considerably improve the wear resistance and also scrape resistance of the finish, which is 2-5 times higher than that of the traditional finish. After nano-alumina is added to the paint, a very fine, consistent and also tough network framework can be formed on the paint surface area, which secures the polymer paint layer from damages. the scratch resistance of nano-paint is 3 times greater than that of the original paint. it is widely used in vehicle paint and more. The addition of nano-aluminum trioxide can substantially enhance the firmness of the coating, and also concerning 20% can reach 6-7H. The transparency of the covering is not influenced.
Plastic, rubber, glue, 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 resin matrix as well as fillers, enhance the thermal conductivity of matrix materials and also not reduce its mechanical properties, surface therapy agents such as combining agents are generally utilized to boost the thermal conductivity.
Nano alumina has high purity, uniform particle dimension as well as great diffusion. When about 10% alumina is added to the sintered porcelains, the creating pressure rises, which can reduce the variety of pores, thus increase the density of the ceramic blank, enhance the density as well as mechanical buildings of the sintered alumina ceramics, and also minimize the sintering temperature level better.
Nano alumina for metallurgy has tiny bit dimension, big specific area and also high activity, including 1-3% nano-alumina to prevent matrix densification and also grain dimension, enhance solidity, boost electrical conductivity and also mechanical residential or commercial properties, and boost melting point and also heat resistance.
Alumina bits are consistent, have high sphericity, and also are precision polishing powder, is an excellent product for metallographic sprucing up, yet likewise ideal for stainless-steel mirror polishing, titanium polishing, cast iron polishing, light weight aluminum mirror sprucing up, rock mirror polishing, paint sprucing up, material polishing, PCB circuit board polishing, glass sprucing up, optical glass, glasses lens sprucing up, material lens polishing, sapphire polishing, LED sprucing up, germanium polishing. Zinc sprucing up, quick sprucing up, excellent brightness, no scrapes.
