What is Alumina Nanoparticle used for
Lithium battery diaphragm finish material:
High purity nano alumina is applied to the favorable and negative diaphragm of lithium battery as a ceramic covering, which plays the duty of warm resistance, heat resistance and also insulation, so as to protect against the power battery from short circuit due to high temperature as well as diaphragm melting.
Ingredients for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal security, cycle performance and overcharge resistance, prevent the development of oxygen and also the disintegration of LiPF6, stay clear of direct contact between LiCo02 and also electrolyte, lower the loss of electrochemical details capacity, and improve the electrochemical specific capability of LiCoO2.
High purity γ& gamma;-kind nano-alumina is a permeable material with an inner surface area of hundreds of square meters per gram, high activity and also strong adsorption capability. It is a frequently made use of adsorbent, stimulant as well as stimulant provider in petroleum refining as well as petrochemical market; it is a deacidizing agent for transformer oil and also generator oil in sector, as well as it is likewise made use of for chromatographic evaluation; it is a neutral and also solid desiccant busy, its drying capacity is no less than that of phosphorus pentoxide, and also it can be regrowed as well as reused after home heating listed below 175 ℃ for 6-8 hrs.
Powder finish anti-caking:
In summer, nano-alumina can properly prevent powder coating caking. Nanometer aluminum trioxide utilized in powder finishes can improve the fluffiness of powder finishings and have good anti-caking impact. It has good storability for powder coatings used in high temperature and high moisture setting.
Covering, rubber, plastic wear-resistant as well as hardening agent:
Including 5-20% nano-alumina, the finishing can considerably boost the wear resistance and scrape resistance of the finish, which is 2-5 times higher than that of the traditional layer. After nano-alumina is included in the paint, an extremely great, uniform and hard network framework can be formed on the paint surface area, which secures 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 utilized in automobile paint and so forth. The addition of nano-aluminum trioxide can considerably enhance the firmness of the finish, as well as regarding 20% can reach 6-7H. The openness of the finishing is not affected.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large spherical dental filling. In order to enhance the compatibility of material matrix and also fillers, enhance the thermal conductivity of matrix materials as well as not reduce its mechanical buildings, surface treatment agents such as combining representatives are commonly used to enhance the thermal conductivity.
Nano alumina has high pureness, uniform bit size as well as great diffusion. When about 10% alumina is included in the sintered porcelains, the developing stress rises, which can decrease the variety of pores, therefore raise the thickness of the ceramic space, improve the density and mechanical homes of the sintered alumina porcelains, and also minimize the sintering temperature more effectively.
Nano alumina for metallurgy has small bit dimension, big specific surface and also high task, including 1-3% nano-alumina to prevent matrix densification and grain size, boost solidity, enhance electric conductivity as well as mechanical properties, and also improve melting factor as well as heat resistance.
Alumina particles are uniform, have high sphericity, and also are accuracy brightening powder, is a good product for metallographic polishing, however additionally ideal for stainless-steel mirror sprucing up, titanium sprucing up, cast iron sprucing up, aluminum mirror polishing, rock mirror polishing, paint polishing, material sprucing up, PCB circuit card polishing, glass sprucing up, optical glass, glasses lens sprucing up, material lens polishing, sapphire sprucing up, LED polishing, germanium polishing. Zinc polishing, fast sprucing up, good illumination, no scrapes.
