Knowledge points related to flake graphite

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.In lithium-ion battery materials, anode materials are the key to determining battery performance. As a high crystallinity graphite material, the particle size of flake graphite directly affects the specific surface area of the electrode and the proportion of edge carbon atoms, which has a significant impact on the irreversible specific capacity of electricity. Therefore, flake graphite plays a crucial role in batteries.Flake graphite is one of the important materials for lithium batteries due to its high electronic conductivity, large lithium ion diffusion coefficient,

The main methods of graphite purification

1 Flotation methodFlotation method is a commonly used method for purifying minerals. Due to the difficulty of water infiltration on the surface of graphite, it has good floatability and is easy to separate from impurity minerals. In China, flotation method is generally used for beneficiation of graphite.The flotation of graphite raw ore generally uses the positive flotation method first, followed by reverse flotation of the positive flotation concentrate. High grade graphite concentrate can be obtained by using flotation method. The grade of flotation graphite concentrate can usually reach 80% to 90%, and the purity can reach around 98% by using multi-stage grinding.The commonly used collectors for flotation of crystalline graphite are kerosene, diesel, heavy oil, sulfonic acid esters, sulfate esters, phenols, and carboxylic acid esters. The commonly used foaming agents are 2 # oil, 4 # oil, terpineol oil, ether alcohol, and butyl ether oil. The adjusting agents are lime and sodium ca

Insufficient technical investment in domestic graphite powder production enterprises

As a policy of each graphite deep processing production company, it is far from reality. The single product function is not bad, but the stability of batch production is doubtful, and the consistency of each batch of products cannot be guaranteed. A professor of deep processing and production of graphite powder believes that the exchanges of different types of different types of information for the deep processing and production of graphite powder will be a long process. The gap between many companies is that they have excellent experiments but cannot produce in batches. The following editors analyze the reasons for the lack of technical investment in domestic graphite powder production enterprises:It is not related to the automation control of the company's production line, which is a systematic problem. At present, graphite powder deep processing production equipment accounts for more than half of the imported equipment. Graphite mineral resources are a very important strategic reso

The Properties of Graphite and Its Application in Smelting

Graphite undergoes special forming methods to achieve its industrial application characteristics, namely special graphite. The three high graphite is commonly known as the three high graphite in the industry, but not all three high graphite is isostatic pressure graphite. In addition, there are materials such as molded and extruded graphite, which, due to their special structure, have high temperature resistance, conductivity, thermal conductivity, lubrication, chemical stability, and plasticity Characteristics such as thermal shock resistance.The application of graphite in the metallurgical industry is due to its high temperature resistance, thermal conductivity, stable chemical properties, and thermal shock resistance. In the metallurgical industry, graphite is mainly used as a refractory material. We are familiar with graphite crucibles, refractory bricks, and casting molds in the metallurgical industry. Graphite products are closely related to the smelting industry, and in the ste

The case of graphite boat is harmful to the proportion of the surface layer

The harm of the shape of the graphite boat to the surface layer of the surface layer will use the new graphite boat and the use of the old graphite boat for more than three years to saturate the coating on the surface layer of the PECVD surface. The flat surface of the new graphite boat is good, and the graphite boat has the same conductivity. The plastic membrane molecular formula can be uniformly accumulated on the surface of the single crystal silicon wafer, and the uniformity between the pieces is higher.After the new graphite boat is saturated, there are still some plasma accumulated on the graphite boat when the accumulation is accumulated. When the number of running times is less than thirty times, as the number of running times increases, the plasma accumulated on the graphite boat decreases. Essence After the number of running times exceeds thirty times, as the number of uses increases, the inner wall of the graphite tape and the single crystal silicon tablets touch the plast

Flake graphite processing

Flake graphite is obtained by mining and processing from graphite mines. The types of ore mined are different, and when processing flake graphite, it is also necessary to process it correctly based on the characteristics of the graphite ore. So how should we proceed with the operation? Let's have a simple understanding of flake graphite below.1. Mineral processing method for flake graphite cryptocrystalline graphite.Cryptocrystalline graphite crystals are very small, hence also known as microcrystalline graphite. Graphite particles are usually embedded in clay and difficult to separate. Due to the high grade of the raw ore (usually containing carbon), many graphite mines directly crush and process the extracted ore, selling graphite powder products.2. Mineral processing method for crystalline graphite in flake graphite.The natural floatability of crystalline graphite is good, and it is basically used in China. Due to the particle size of graphite sheets being one of its most important
