What is the application scope of industrial graphite powder

Explain the purpose of flake graphite in detail?

Flake graphite is a natural graphite ore, similar in shape to fish scales, and is a hexagonal crystal with a layered structure. Now this product has good acid and alkali resistance, high temperature resistance, conductivity, thermal conductivity, and lubrication performance. Now widely used as refractory materials and coatings in the smelting industry. Such as magnesia carbon bricks, crucibles and other military pyrotechnic stabilizers, desulfurization accelerators in the smelting industry, pencil lead, carbon brushes in the electrical industry, electrodes in batteries, catalysts in the chemical industry, etc. Lubricants, release agents, wire drawing agents, conductive coatings, etc. Scale graphite has a lubricating effect, so it can play a lubricating role in the lock cylinder, making the door easy to open. Flake graphite also has characteristics such as intact flake crystals, thin flakes with good toughness, stable physical and chemical properties, conductivity, temperature resistan

Brief Introduction to the Use Technology of Graphite Electrodes

1. Varieties of graphite electrodesElectric arc steelmaking furnaces are generally divided into three categories, namely ordinary power electric furnaces, high-power electric furnaces, and ultra-high power electric furnaces. Corresponding to the power level of electric furnace steelmaking, graphite electrodes are also divided into three types, namely ordinary power graphite electrodes (code RP level), high-power graphite electrodes (code HP level), and ultra-high power graphite electrodes (code UHP level). The nominal diameter of the electrode ranges from 75mm to 700mm. The physical and chemical properties of high-power and ultra-high-power graphite electrodes are superior to ordinary power graphite electrodes, such as low resistivity, high bulk density, high mechanical strength, low linear expansion coefficient, and excellent antioxidant performance. The physical properties of three types of graphite electrodes are shown in Table 1.Selection of graphite electrodes for AC arc steelmak

What are the characteristics of graphite?

What are the characteristics of graphite? Graphite is a slot -type graphite dish, which contains one or several strips of two slot surfaces and bottom -end support points. The relative grooves of the hole, the respective design schemes of the relative two grooves are at least one exhaust pipe square groove, and the design scheme of each of the two -slot surface of the support point of the bottom support point has an corner slot. The design scheme below the highlight of the two neighboring W -shaped dual slots is based on the parallel surface of the slogan and cross -section of the design scheme.This utility model patent makes the hard alloy knife -shaped piece -shaped product in the process of boiling glue in the whole process of pillar opening and vacuum pumping. Technical majors make graphite and graphite products for customers. Welcome customers to visit everyone in person.

What is the difference between scales graphite and asbestos?

1. Scale graphite has better high temperature resistance performanceThe scale of the scale graphite enhanced composite pads can withstand the high temperature of 1650 ° C. Even if the chemical equipment is melted, it is still safe and intact. When the asbestos products are at 500 ° C, the crystalline water inside will decompose to make itself powder and lose its effect. In many industrial fields, it is carried out at high temperatures. The nature of scales graphite makes it more suitable for this role.2. Synthine graphite is easier to useThe pads of scales graphite are only half of asbestos products, which means that to achieve the same sealing effect, the power of tightening the screw can be much smaller. The scales graphite not only has the above obvious characteristics, but also has excellent sealing performance, good compression, elasticity, elasticity, elasticity, The characteristics of good antioxidant, strong self -lubrication and plasticity, good conductivity, high gravity, an

Can expand graphite development

Graphite crystals have a hexagonal layer -shaped structure composed of carbon elements. The carbon atoms on the layer of flat plane are combined with powerful covalent bonds. Therefore, under appropriate conditions, a variety of chemicals such as acid, alkaline metals, and salt can be inserted into the graphite layer, and a new chemical phase -Graphite Intercities on compounds (referred to GIC). When this intervertebral compound is heated to an appropriate temperature, it can quickly decompose instantly, generating a large amount of gas, so that the graphite is expanded into a new substance of worm -shaped, that is, the expansion of the intervertebral compound of the expansion. graphite.The expansion graphite was first discovered by the German SChaufautl. In 1841, Schaufautl soaked natural graphite in a mixture of thick HNO3 and thick H2SO4. In 1963, he first applied for expanding graphite manufacturing technology patents and industrialized production in 1968.The above is some of the
