Lithium battery diaphragm finishing product:
High pureness nano alumina is put on the favorable and unfavorable diaphragm of lithium battery as a ceramic coating, which plays the duty of warmth resistance, high temperature resistance and also insulation, so regarding prevent the power battery from short circuit because of heat as well as diaphragm melting.
Ingredients for cathode products of lithium batteries:
High purity nano-alumina doped with lithium cobalt as well as lithium manganate can improve thermal stability, cycle performance and also overcharge resistance, hinder the formation of oxygen and the decomposition of LiPF6, stay clear of direct call between LiCo02 and electrolyte, minimize the loss of electrochemical details ability, and enhance the electrochemical certain ability of LiCoO2.
High purity γ& gamma;-kind nano-alumina is a porous compound with an interior surface of numerous square meters per gram, high activity and solid adsorption capability. It is a typically used adsorbent, stimulant as well as driver carrier in oil refining and petrochemical sector; it is a deacidizing agent for transformer oil and turbine oil in market, and also it is additionally utilized for chromatographic analysis; it is a neutral and also solid desiccant in the laboratory, its drying capability is no much less than that of phosphorus pentoxide, as well as it can be restored as well as reused after heating listed below 175 ℃ for 6-8 hours.
Powder covering anti-caking:
In summer, nano-alumina can efficiently stop powder finishing caking. Nanometer aluminum trioxide made use of in powder finishes can enhance the fluffiness of powder finishes and also have good anti-caking effect. It has good storability for powder layers utilized in heat and also high humidity environment.
Covering, rubber, plastic wear-resistant and also hardening agent:
Adding 5-20% nano-alumina, the layer can greatly enhance the wear resistance and scratch resistance of the finishing, which is 2-5 times more than that of the traditional layer. After nano-alumina is contributed to the paint, a really fine, uniform as well as difficult network structure can be formed on the paint surface, which secures the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times greater than that of the initial paint. it is commonly utilized in car paint and so on. The addition of nano-aluminum trioxide can dramatically enhance the firmness of the finish, and concerning 20% can get to 6-7H. The openness of the coating is not affected.
Plastic, rubber, adhesive, paint thermal conductivity:
Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big round filling. In order to boost the compatibility of material matrix and fillers, improve the thermal conductivity of matrix products and not decrease its mechanical properties, surface area treatment representatives such as combining agents are typically utilized to enhance the thermal conductivity.
Nano alumina has high purity, consistent fragment dimension as well as good diffusion. When around 10% alumina is added to the sintered ceramics, the forming stress increases, which can reduce the number of pores, thus increase the thickness of the ceramic blank, improve the density and mechanical buildings of the sintered alumina porcelains, and lower the sintering temperature level more effectively.
Nano alumina for metallurgy has little fragment size, large certain surface area as well as high activity, adding 1-3% nano-alumina to avoid matrix densification and also grain dimension, boost solidity, enhance electrical conductivity and also mechanical residential properties, and improve melting point and high temperature resistance.
Alumina fragments are uniform, have high sphericity, and also are accuracy brightening powder, is an excellent material for metallographic polishing, but also ideal for stainless-steel mirror polishing, titanium sprucing up, cast iron sprucing up, aluminum mirror sprucing up, rock mirror sprucing up, paint sprucing up, resin sprucing up, PCB circuit board polishing, glass polishing, optical glass, glasses lens polishing, resin lens sprucing up, sapphire sprucing up, LED sprucing up, germanium polishing. Zinc polishing, quick polishing, good brightness, no scrapes.
