Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe

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 are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

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.

Graphite products and other purposes

Defense industryIn the defense industry, the nozzle of solid fuel rockets is also used to make solid fuel rockets, the nasal cone of the missile, the parts of the universe navigation equipment, the insulation material and the anti -ray material.Anti -anti -rust and anti -rust materialGraphite can prevent boilers from scaling. Tests from relevant units show that adding a certain amount of graphite powder (about use per ton of water) to the water can prevent the surface of the boiler from scaling. In additionWith the continuous development of science and technology, people have also developed many new uses on graphite. Flexible graphite products. Flexible graphite, also known as expansion graphite, is a new graphite product developed in the age. The United States has studied successful flexible graphite sealing materials, solving the problem of atomic energy valve leakage, and then Germany, Japan, and France have also begun to develop and produce. In addition to the characteristics of n

Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces
