Graph

Graphite is a raw material that is stable in physical properties, anti -corrosion, and drugs such as acid, alkali and other drugs that is not easy to produce reflected. It is common in the production of processed graphite board, graphite board, graphite anode board, graphite bipolar tablets and other products. Petrochemical equipment, mechanical engineering, electronic device industry chain, China nuclear industry and national defense security are all used in areasBecause graphite can be used to manufacture refractory insulation materials, conductive raw materials, metal composite materials, lubricating liquid, heat -resistant rubber seals, corrosion -resistant raw materials, insulation materials, raw materials, wear resistance and radiation -proof materials, etc.1. Fire. Graphite refractory insulation materials are mainly casting raw materials, magnesium carbon bricks and aluminum graphite refractory insulation materials.2. conductivity. There are also television series graphics card

How to distinguish whether Gwangba is clean and tidy?

1. Determine that the graphite boat has no acid and alkali ingredients. (After immersion, you can use pH to detect water or graphite boats that have been used as neutralized to determine the results of the cleaning.)2. Check out the surface layer, graphite guarding point and graphite boat, and whether there are residues of silicon nitride.3. Try the ceramic stick and porcelain sleeve with the dust -free paper -free paper -free paper -free paper.Remarks: The above rules are distinguished under the processing process of all normal washing boats. When the ceramic stick is broken during the whole process of laundering, the insistence is too large, and it needs to be immediately disassembled to prevent everything that endangers the graphite boat. Normal application.

Graphite: the natural king of electricity

Graphite, this dark gray mineral, is known as the "natural king of electricity" because of its excellent electrical conductivity. Its electrical conductivity is better than many other materials, making graphite occupy a pivotal position in the electronics industry. Whether it is the manufacture of electrodes, batteries or other electronic devices, graphite plays an irreplaceable role.In addition, graphite ha

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

How is expanded graphite produced?

Due to the fact that graphite is a non-polar material, it is difficult to intercalate with small polar organic or inorganic acids alone, so oxidants are usually required. The chemical oxidation method generally involves soaking natural flake graphite in a solution of oxidants and intercalators. Under the action of strong oxidants, graphite is oxidized, causing the neutral network of planar macromolecules in the graphite layer to become positively charged planar macromolecules. Due to the extrusion effect of isotropic positive charges between positively charged planar macromolecules, the spacing between graphite layers increases, and the intercalation agent is inserted between the graphite layers to form expanded graphite.Expanded graphite will rapidly shrink when heated at high temperatures, with shrinkage times reaching tens to hundreds or even thousands of times. The apparent volume of contracted graphite reaches 250-300 milliliters/gram or more. The shrunken graphite is in the shap

What are the characteristics of graphite bearings?

Graphite bearings are important high-temperature bearings that utilize the self-lubricating, high-temperature resistance, and chemical inertness of graphite materials to operate under high temperature and strong corrosion conditions that ordinary bearings cannot withstand. The main functions of graphite bearings are:

Operating Techniques for Graphite Crucibles

Graphite crucible is a very excellent smelting tool that has been praised by people in the metal smelting industry. Its usage method is simple. Below, we will introduce some matters that need to be mastered when using it.The main uses of graphite crucibles include evaporation, concentration or crystallization of solutions, and burning of solid substances. It should be noted that although graphite crucibles have strong temperature adaptability and can be directly heated, they cannot be suddenly cooled after heating. If necessary, use crucible pliers to remove the crucible instead of using technical means to quickly cool it. Because it is directly heated and the heated contents are metals with extremely high dissolution temperatures, the required energy and safety requirements are relatively high. Therefore, during the heating process of the crucible, it is necessary to have a stable environment to ensure the safety and effectiveness of the operation. In general, manufacturers choose to

Battery material, promote renewable energy development

In recent years, with the increasingly serious problems of environmental pollution and energy shortage, renewable energy as a clean, low -carbon, and sustainable development model has gradually been given important strategic significance. Among the applications of renewable energy, batteries as energy storage equipment are also an indispensable part of them. In order to further promote the development of renewable energy, we need to continuously explore new battery materials to improve the power density, cycle life and security of the battery.At present, researchers have proposed many new battery materials, such as lithium ion batteries, sodium ion batteries, zinc air batteries, etc. These battery materials can better meet the needs of energy storage and utilization compared to traditional lead -acid batteries, nickel -metal hydride batteries. Moreover, in the production process, the energy and materials they consume are also greatly reduced, which is more in line with the requirement

The application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl
