Common preparation methods for expandable graphite

1. Chemical intercalation method: the initial raw material for preparation is high carbon flake graphite, and other chemical reagents such as concentrated sulfuric acid (more than 98%), hydrogen peroxide (more than 28%), Potassium permanganate, etc. use industrial grade reagents. The general steps for preparation are as follows: under appropriate temperature, hydrogen peroxide solution with different ratios, natural flake graphite and concentrated sulfuric acid are added in different procedures, and reacted for a certain time under constant agitation, and then washed with water to neutral, Centrifuge separation, dehydrate and vacuum dry at 60 ℃.2. Electrochemical method: Treating graphite powder in a strong acid electrolyte to produce expandable graphite, hydrolyzing, cleaning, and drying. As a strong acid, sulfuric acid or nitric acid is mainly used. This method produces expandable graphite with low sulfur content.3. Ultrasonic oxidation method: In the process of preparing expandable

How to solve the corrosion of the device in the scale graphite?

How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate, and hydrofluoric acid, includin

How are graphite electrodes consumed in electric furnace steelmaking?

The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, as well as to steelmaking operations and processes.(1) Electrode end consumption. Its consumption includes the sublimation of graphite material caused by high arc temperature, as well as the loss of chemical reactions between the electrode end and molten steel and slag. The electrode end consumption is also related to whether the electrode is inserted into the molten steel to increase.(2) Oxidation loss on the outer surface of the electrode. In recent years, in order to improve the smelting rate of electric furnaces, oxygen blowing has been widely used, which has led to an increase in electrode oxidation losses. In general, the oxidation loss on the outer circular surface of the electrode accounts for about 50% of the total electrode consumption.(3) Residual loss of electrodes or connectors. A small section of electrode or connector that is continuously used at the connection between

What you need to know in the daily use of graphite mold

Due to the special structure of the graphite mold. Therefore, in daily use, these special properties should also be understood by us.1. High temperature resistant type: the melting point of graphite is 3850+50°C, and the boiling point is 4250°C. Even in ultra-high temperature arc burning, the thermal expansion coefficient is very small, and the strength of graphite increases with the increase of temperature. At 2000°C , graphite strength increased - times;2. Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance;3. Plasticity: Graphite has good toughness and can be made into very thin sheets;4. Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acid, alkali and organic solvents;5. Thermal shock resistance: When graphite is used at room temperature, it can withstand drastic changes in temperature wi

The position and role of carbon industry in the development of the national economy

Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an
