What is Alumina Nanoparticle used for
Lithium battery diaphragm coating product:
High pureness nano alumina is put on the favorable and unfavorable diaphragm of lithium battery as a ceramic layer, which plays the function of warm resistance, high temperature resistance and insulation, so regarding protect against the power battery from short circuit due to heat as well as diaphragm melting.
Additives for cathode products of lithium batteries:
High pureness nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal stability, cycle efficiency as well as overcharge resistance, hinder the development of oxygen and also the decomposition of LiPF6, prevent straight get in touch with in between LiCo02 as well as electrolyte, reduce the loss of electrochemical certain capability, as well as boost the electrochemical specific ability of LiCoO2.
High pureness γ& gamma;-kind nano-alumina is a porous compound with an inner surface area of numerous square meters per gram, high task as well as solid adsorption capability. It is a frequently used adsorbent, driver and also driver service provider in oil refining and also petrochemical market; it is a deacidizing agent for transformer oil and turbine oil in market, as well as it is likewise used for chromatographic evaluation; it is a neutral and also solid desiccant in the laboratory, its drying capability is no much less than that of phosphorus pentoxide, and also it can be regenerated and also reused after home heating below 175 ℃ for 6-8 hrs.
Powder finishing anti-caking:
In summer, nano-alumina can effectively avoid powder coating caking. Nanometer light weight aluminum trioxide used in powder coverings can improve the fluffiness of powder finishes as well as have excellent anti-caking impact. It has great storability for powder finishings used in heat and also high moisture atmosphere.
Covering, rubber, plastic wear-resistant and hardening agent:
Including 5-20% nano-alumina, the layer can considerably improve the wear resistance and scrape resistance of the layer, which is 2-5 times more than that of the standard finishing. After nano-alumina is added to the paint, a really fine, consistent and hard network framework can be based on the paint surface, which shields the polymer paint layer from damage. the scrape resistance of nano-paint is 3 times higher than that of the initial paint. it is commonly utilized in car paint and more. The enhancement of nano-aluminum trioxide can considerably enhance the hardness of the coating, and concerning 20% can reach 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, big round filling. In order to improve the compatibility of resin matrix as well as fillers, improve the thermal conductivity of matrix products as well as not decrease its mechanical residential properties, surface area treatment representatives such as combining representatives are frequently used to improve the thermal conductivity.
Nano alumina has high purity, uniform fragment size and good diffusion. When around 10% alumina is included in the sintered ceramics, the forming stress increases, which can decrease the variety of pores, hence enhance the thickness of the ceramic space, enhance the thickness as well as mechanical homes of the sintered alumina ceramics, and decrease the sintering temperature level better.
Nano alumina for metallurgy has small bit dimension, big specific area and high activity, adding 1-3% nano-alumina to stop matrix densification and grain size, improve solidity, enhance electrical conductivity and also mechanical residential properties, and also improve melting point and also heat resistance.
Alumina particles are consistent, have high sphericity, and also are accuracy polishing powder, is a good product for metallographic polishing, yet also appropriate for stainless-steel mirror polishing, titanium polishing, cast iron polishing, light weight aluminum mirror sprucing up, stone mirror sprucing up, paint polishing, material polishing, PCB circuit board polishing, glass sprucing up, optical glass, glasses lens polishing, material lens polishing, sapphire polishing, LED polishing, germanium polishing. Zinc sprucing up, rapid sprucing up, excellent brightness, no scratches.
