Lithium battery diaphragm finishing product:
High purity nano alumina is applied to the positive and also negative diaphragm of lithium battery as a ceramic coating, which plays the function of heat resistance, heat resistance as well as insulation, so regarding prevent the power battery from brief circuit as a result of high temperature and also diaphragm melting.
Additives for cathode products of lithium batteries:
High pureness nano-alumina doped with lithium cobalt as well as lithium manganate can enhance thermal security, cycle performance and also overcharge resistance, hinder the development of oxygen and the decomposition of LiPF6, avoid direct call between LiCo02 as well as electrolyte, reduce the loss of electrochemical details ability, and improve the electrochemical details capacity of LiCoO2.
High purity γ& gamma;-type nano-alumina is a permeable substance with an inner surface of thousands of square meters per gram, high activity and also solid adsorption ability. It is a generally utilized adsorbent, driver and catalyst service provider in petroleum refining and also petrochemical market; it is a deacidizing agent for transformer oil and turbine oil in sector, and it is also utilized for chromatographic evaluation; it is a neutral as well as strong desiccant busy, its drying ability is no less than that of phosphorus pentoxide, as well as it can be regrowed and reused after home heating below 175 ℃ for 6-8 hrs.
Powder finishing anti-caking:
In summertime, nano-alumina can properly prevent powder coating caking. Nanometer aluminum trioxide used in powder finishes can enhance the fluffiness of powder finishings as well as have good anti-caking effect. It has excellent storability for powder coverings used in high temperature and also high moisture environment.
Coating, rubber, plastic wear-resistant and hardening representative:
Including 5-20% nano-alumina, the finishing can significantly boost the wear resistance and scratch resistance of the covering, which is 2-5 times greater than that of the typical finish. After nano-alumina is included in the paint, a really fine, consistent as well as tough network structure can be formed on the paint surface area, which shields the polymer paint layer from damage. the scrape resistance of nano-paint is 3 times more than that of the original paint. it is commonly used in automobile paint and so forth. The addition of nano-aluminum trioxide can considerably boost the hardness of the layer, and also regarding 20% can get to 6-7H. The openness of the covering is not influenced.
Plastic, rubber, sticky, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large spherical filling. In order to enhance the compatibility of material matrix and fillers, boost the thermal conductivity of matrix products and also not lower its mechanical properties, surface therapy agents such as coupling agents are frequently made use of to boost the thermal conductivity.
Nano alumina has high purity, uniform fragment dimension and also good dispersion. When about 10% alumina is included in the sintered ceramics, the forming stress increases, which can decrease the variety of pores, hence boost the density of the ceramic blank, boost the thickness as well as mechanical buildings of the sintered alumina porcelains, and also lower the sintering temperature level better.
Nano alumina for metallurgy has small particle dimension, huge details area and high task, including 1-3% nano-alumina to avoid matrix densification as well as grain dimension, boost hardness, boost electrical conductivity and mechanical residential or commercial properties, and improve melting factor as well as heat resistance.
Alumina fragments are uniform, have high sphericity, and are precision polishing powder, is an excellent material for metallographic polishing, but additionally ideal for stainless-steel mirror polishing, titanium sprucing up, cast iron sprucing up, aluminum mirror polishing, rock mirror sprucing up, paint sprucing up, resin sprucing up, PCB circuit board sprucing up, glass sprucing up, optical glass, glasses lens polishing, resin lens sprucing up, sapphire polishing, LED polishing, germanium sprucing up. Zinc sprucing up, rapid polishing, excellent illumination, no scrapes.
