What are the quality characteristics of graphite model

Graphite has a lot of different high -quality characteristics. It is widely used in the metallurgical industry forging, the setting glass of mezzanine, and the industrialization of semiconductor materials. What are the high -quality characteristics of graphite mold? Let's take a look with graphite products manufacturers.1. High -quality heat transfer and conductivity. The conductivity of graphite molds is 100 times higher than that of ordinary mining companies. The heat transfer is beyond metal composite materials such as steel, iron, and lead. The heat transfer coefficient decreases with the temperature, and even at a very high temperature, the graphite becomes anrmal insulation.2. Very good thermal resistance. The solution point of graphite is 385050 ° C, and the melting point is 4250 ° C. Even if it is burned by high temperature, high voltage and electricity, the net damage is not large, and the line expansion coefficient is not large.3. Excellent thermal shock -resistant character

Introduction to the characteristics of flake graphite

1. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks. In the actual production process, carbon refractory ma

Maintenance and upkeep of graphite crucibles

The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame. When handling graphite crucibles, it is important to handle them with care and prevent them from falling or shaking. Before using them, they should be baked in a drying equipment or by the furnace to raise the temperature to 500 ℃. The graphite crucible should be placed below the surface of the furnace mouth to prevent wear and tear on the furnace cover. When adding materials, it should be based on the solubility of the crucible, and too much material should not be added to prevent tightening the crucible. The furnace outlet and crucible clamp should conform to the shape of the crucible, and the clamp in the middle should prevent damage to the crucible due to stress on the department. When removing slag and coke from the inner and outer walls of the crucible, it should be gently knocked to prevent damage to the crucible. A suitable distance should be maintained betwee

Nuclear energy uses graphite material

Graphite is one of the deceleration materials and reflective materials used in nuclear reactors. Early reactors are graphite heaps. The nuclear reactor for structural materials use graphite using raw materials, process control, and finished product inspection than graphite electrodes. The nuclear reactor must have the following performance with graphite , High heat shock, good deceleration performance to fast neutron, stable size under radiation, and very small impurities. Boron, cadmium and other elements that are easy to absorb neutron should be strictly controlled.Nuclear graphite must have a high volume density M because the deceleration of graphite on fast neutron is relying on the collision effect of fast neutron to carbon atoms. One of the main indicators of nuclear graphite M is also directly related to the pore rate and penetration rate of graphite. In order to avoid the loss of nuclear fuel and heat carrier, M should reduce the pores and penetration rates to a certain level.

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.
