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.

The formation of KISH graphite

Whether it plays an important role in the growth of KISH graphite or the growth of KISH graphite according to layer -like crystal, oxygen is an important role. Practice has proved that when the co -crystal iron fluid is exposed to the air, the KISH graphite is easy to form; turning the iron solution and the update surface can exacerbate the precipitation of KISH graphite. The action of oxygen is to form SiO2 as the base of KISH graphite nucleus. The temperature of the iron liquid temperature at below 1400 ° C is severe than high temperature because of SiO2, which is unstable above 1400 ° C. The precision phenomenon of KISH graphite cannot be seen in the low Si or Si iron liquid, which shows that the existence of SIO2 has an impact on the formation of KISH graphite that cannot be ignored.The cooling speed is the basic process conditions formed by the formation of KISH graphite when the existence of oxygen (such as hydrogen protection). KISH graphite can only be formed at a lower coolin

What aspects will endanger the use period of graphite board

First, the quality of the production and processing of graphite board is the direct cause of the life of the application of its application. Graphite board production and processing must be careful to reach the overall goal of the standard. For example, pre -immersing this level must be well -proportioned, so that its resistance is basically unremittingly consistent, so that the conductivity can be proportioned to prevent the entire production process from occurring in the process of production Some part is complete, but some of the erosion is serious, so that all personnel come out to consume.In the second place, the graphite board must have an excellent office environment, which is the fundamental to prolong life. During the entire production process, reduce the impact and clean up the office environment. It can check the power circuit on time, produce at the best temperature, and reduce the air oxidation of the gas to its air.In the end, high -quality graphite boards are used to im

How to solve the problem of device corrosion of the scale graphite

How to avoid the corrosion of the equipment on the equipment, thereby reducing the cost of equipment investment and maintenance, and improving production efficiency and profit. It is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but high temperature. Both. 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. The scales graphite also has good thermal conductivity. It is a non -metal material with a thermal conductivity higher than the metal. It ranks in the front position in non -metal materials. 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, including fluoride-containing medium, and the maximum use temperature is 350 ° C-400 ° C. It is the temperature that starts t

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.

Do you know what is the difference between graphite powder and coal powder?

The chemical elements of the two are the same, but the structure is completely different. The coal is a molecular crystal, and the graphite is a atomic crystal. Usually we usually say that C powder is molecular crystals.Graphite: Natural crystal graphite, shaped like fish phosphorus, is a hexagonal crystal system, with layer -like structure, high temperature resistance, conductivity, heat conduction, lubrication, plasticity, acid and alkaline resistance. The scale graphite is divided into four categories according to the fixed carbon content: high pure graphite, high carbon graphite, medium carbon graphite, low -carbon graphite.Graphite powder is soft, gray -black; raw materials have heat -resistant conductivity, which can be used as refractory insulation materials, conductive raw materials and wear -resistant moisturizing raw materials.

Graphite material properties

Graphite materials are mainly composed of polycrystalline graphite and belong to inorganic non-metallic materials. However, they are called semi metals due to their excellent thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than certain metals, and also has a much lower coefficient of thermal expansion, high melting point, and chemical stability than metals. This makes it of great value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compoundsGraphite is another high-temperature resistant material that does not melt at high temperatures. It also has good thermal shock resistance and excellent self-lubricating propertiesThe disadvantage of graphite is its poor seismic performance. It begins to oxidize at 500 ℃ in the atmosphere, and the oxidation rate increases with the increase of temperature
