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

What are the main uses of heating welding graphite mold?

Graphite molds are mostly used to connect the railway track. According to the chemical changes of aluminum and copper powder, the liquid high temperature copper liquid is caused, and the contemporary welding method of excellent performance is used to complete the high temperature caused by chemical reactions.Heating welding is suitable for connecting copper and copper, copper and steel, steel and steel. The solubility is carried out in the heat -resistant graphite mold. The mold shellfish uses a relatively high density and good wear resistance characteristics. It can bear the melting temperature of metal materials such as copper, steel, iron, and iron, and the inflow, flow speed, and its final appearance of molten metal materials are designed.There are many specifications for the type of hedging of the welding of the insulation reactions. Generally, the detailed inspiration reaction welded powder shellfish consists of three parts:1. Graphite molds used in welding welding: mold shells

What issues should be paid attention to when using graphite crucibles

Graphite crucibles have a wide range of uses in the metallurgical industry, and their main function is to hold various liquid metals. As a metallurgical manufacturer, it is necessary to use graphite crucibles, otherwise there may be some problems in later production and use.Although graphite crucibles are of good quality and not easily damaged, they should also be handled with care. Falling or bumping from high altitude may not have a significant impact on its quality, but if it continues to do so for a long time, it may crack or even break. After this situation occurs, there is no way to remedy it, and we can only replace it with a new one.2. Graphite crucibles are prone to moisture, and the product will become soft after being affected by moisture. When struck by some impactful objects, it will deform. And once water enters the graphite crucible, it will affect the raw materials contained inside, causing dilution of the raw materials, and even causing some chemical reactions to furt

The Future Market Prospects of Graphite Powder

The artificial synthesis process and equipment application of scales graphite

At present, the production process of scales graphite is to produce graphite products through the production of natural graphite ore through the production, ball grinding, and flotation, and provide artificially synthetic scale graphite production technology and equipment. Using this device, the grinding graphite particles can be reinstated into large -shaped graphite to improve the utilization rate of graphite. The following editor introduces the artificial synthesis process and equipment application of scales in detail:This device has two relatively rotating ring rules semi -round tanks, or two irregular semi -circular grooves that can be relatively rotated, one of which is fixed as a fixed ring groove, and the feed pores are engraved on the fixed ring groove; The power connection allows the power to drive it to rotate. It is a cycle groove, engraved with the material outlet, and the gap between the fixed ring groove and the mobile ring groove can be adjusted; when the two ring groo

How does pungeable graphite produce?

Because graphite is a non -polar material, it is difficult to use the small polar organic or inorganic acid intercourse alone, so oxidant is usually used. The chemical oxidation method is generally soaked in the solution of the natural scales in the solution of the oxidant and plug -in agent. Under the action of a strong oxidant, graphite is oxidized, making the macromolecular molecule of the graphite layer into a plane macromolecular with a positive charge. Due to the extrusion effect of the iconic charging between the plane macromolecules with a positive charge, the spacing between the graphite layer increases, and the plug -in agent is inserted between the graphite layer and becomes a graphite. When heating at high temperature, puffed graphite will quickly shrink, and the contraction multiple is as high as tens to hundreds or even thousands of times. The apparent volume of shrinking graphite reaches 250-300 ml/gram or more. The contracted graphite is worm -like, with a size of 0.1

What is the purpose of expanding graphite

Adsorption agent of industrial oil.Expansion graphite is easily adsorbed, organic molecules and hydrophobic substances, which are used for water environmental protection. It has an irreplaceable effect of other substances. When it is used in a particle -shaped form to remove oil, according to the size of the oil area and the type of oil on the water surface, its dosage is 1 to LO% /RN, and the adsorption time can be ranging from 15rain to a few H.

Characteristics of Mechanical Processing of Carbon Materials

(1) The organizational structure of carbon materials is formed by the preparation of carbon solid aggregate particles and powder raw materials through a series of production processes, so its cutting is composed of a certain number of particles and dust. The large amount of carbon dust generated during the cutting process not only pollutes the operating environment and affects the health of operators, but also the silicon carbide impurities contained in graphite dust can cause certain wear and tear on machine tool components. Therefore, efficient ventilation and dust removal equipment must be installed in the mechanical processing workshop of carbon materials.(2) Carbon material is a heterogeneous and brittle material, with a considerable range of hardness fluctuations. Roasted carbon products have a high hardness, which makes processing more difficult. Graphite products have a low hardness, making them easy to cut and process. The surface roughness of products processed with carbon m

Artificial graphite application field

In the metallurgical industry, natural scales can be used to produce refractory materials such as magnesium carbon bricks and aluminum carbon bricks due to better antioxidant properties. Artificial graphite can be used as a steelmaking electrode, and the electrodes made of natural graphite are difficult to use to use the steelmaking electric furnaces with strict conditions.In the machinery industry, graphite materials are usually used for wear -resistant and lubricating materials. The lubrication of natural scales graphite is better, which is often used as additives for lubricating oil. The device that transports the corrosive medium is widely used by artificial graphite pistons, sealing rings and bearings. There is no need to add lubricating oil during work. Natural graphite and polymer resin composite materials can also be used in the above fields, but wear resistance is not as good as artificial graphite.In the chemical industry, artificial graphite has the characteristics of corro
