Lithium battery diaphragm finish material:
High purity nano alumina is related to the positive as well as unfavorable diaphragm of lithium battery as a ceramic layer, which plays the function of heat resistance, heat resistance as well as insulation, so regarding protect against the power battery from brief circuit because of high temperature and also diaphragm melting.
Ingredients for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt and also lithium manganate can improve thermal security, cycle efficiency and overcharge resistance, inhibit the formation of oxygen and the decay of LiPF6, avoid direct get in touch with in between LiCo02 and also electrolyte, minimize the loss of electrochemical specific capability, and improve the electrochemical details capacity of LiCoO2.
High pureness γ& gamma;-type nano-alumina is a permeable material with an interior surface of numerous square meters per gram, high task and solid adsorption ability. It is a typically utilized adsorbent, driver and stimulant service provider in petroleum refining and petrochemical sector; it is a deacidizing representative for transformer oil and also generator oil in sector, and also it is likewise used for chromatographic evaluation; it is a neutral and strong desiccant busy, its drying capability is no much less than that of phosphorus pentoxide, and also it can be regrowed and also recycled after home heating below 175 ℃ for 6-8 hrs.
Powder coating anti-caking:
In summertime, nano-alumina can effectively protect against powder finish caking. Nanometer aluminum trioxide made use of in powder finishes can enhance the fluffiness of powder finishes as well as have great anti-caking impact. It has excellent storability for powder coverings utilized in high temperature and also high moisture environment.
Coating, rubber, plastic wear-resistant as well as hardening representative:
Adding 5-20% nano-alumina, the coating can substantially enhance the wear resistance and scrape resistance of the layer, which is 2-5 times more than that of the traditional covering. After nano-alumina is added to the paint, a really fine, uniform as well as difficult network framework can be formed on the paint surface area, which protects the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times more than that of the initial paint. it is widely used in vehicle paint and so on. The addition of nano-aluminum trioxide can dramatically improve the solidity of the covering, and also concerning 20% can get to 6-7H. The openness of the finish is not impacted.
Plastic, rubber, adhesive, 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 and also fillers, boost the thermal conductivity of matrix products and also not minimize its mechanical residential or commercial properties, surface treatment agents such as combining representatives are commonly made use of to enhance the thermal conductivity.
Nano alumina has high purity, consistent bit size and good diffusion. When around 10% alumina is added to the sintered porcelains, the developing pressure boosts, which can reduce the number of pores, therefore enhance the thickness of the ceramic blank, improve the density and also mechanical residential or commercial properties of the sintered alumina porcelains, and lower the sintering temperature better.
Nano alumina for metallurgy has tiny particle dimension, large certain area and high activity, adding 1-3% nano-alumina to stop matrix densification as well as grain dimension, improve firmness, improve electric conductivity and also mechanical residential or commercial properties, and enhance melting factor and high temperature resistance.
Alumina fragments are uniform, have high sphericity, and are precision brightening powder, is a great material for metallographic sprucing up, but also appropriate for stainless-steel mirror polishing, titanium sprucing up, cast iron sprucing up, light weight aluminum mirror sprucing up, rock mirror sprucing up, paint polishing, material sprucing up, PCB circuit card sprucing up, glass sprucing up, optical glass, glasses lens polishing, resin lens polishing, sapphire sprucing up, LED sprucing up, germanium polishing. Zinc polishing, fast polishing, good brightness, no scratches.
