What are the main expanded graphite equipment?

The difference between expandable graphite and expandable graphite is that the expandable graphite is a process that has undergone expansion and is large in volume. The expandable graphite does not undergo expansion and has the characteristics of rapid expansion in case of high temperature. Qingdao Huatai expandable graphite can be used to produce fireproof products.

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

Causes of impure expandable graphite powder

1. The purity of high-purity graphite in the selection of production raw materials is immediately related to the ash content of the selected raw materials under the same production conditions. Civil expandable graphite products have the following pattern: those with high ash content in raw materials also have high ash content in their products. Therefore, the ash content of petroleum coke selected for the production of nuclear high-purity graphite is specified in the mouth. Below 15%, although the boron composition is required, analysis will be conducted, and the specific data information is all in 0. 5pp. Below. The total ash content of the product was divided into 5 parts in ppm, with boron content in the parts. The thermal neutron absorption cross section of the LPPM is 3. Eight times three. 94 millibars.2. The high temperature quenching and tempering treatment and other halogenation solutions have a fundamental impact on the removal of ash, as well as whether or not halogenation s

The relationship between scales graphite and nuclear graphite

1. Different applications of scales graphite and nuclear graphite.Scales graphite has excellent performance such as high temperature resistance, heat conduction, conductivity, lubrication and other excellent performance. It is an indispensable resource for the cultivation of the development of emerging industries and the transformation and upgrading of traditional industries. The nuclear graphite is mainly used as graphite materials in the nuclear industry, including the atomic reactor with neutron chronic agents and reflexes, the production of hot column graphite for the production of isotopes, and the spherical graphite and block graphite for high -temperature gas and cold piles.2. Scales graphite and nuclear graphite are different branches of graphite materials.Graphite -like crystals are complete, thin and tough, their physical and chemical properties are stable, and they have good temperature resistance, lubrication, conductivity, heat shock resistance, corrosion resistance and a

What are the steps of carbon felt purification?

Carbon felt is a major element in many alloy products, so carbon felt purification plays an important role in alloy production. Meanwhile, in the smelting process of metal silicon, silica, ore, etc. are usually used. Silicon slag will also be produced during the smelting process, and silicon slag also contains a certain amount of industrial carbon felt, so we can use carbon felt slag to further purify carbon felt.The first step is to separate the obvious light-colored slag and dark-colored slag from the silicon slag with a manual hammer, and then use the separation principle to further separate the silicon content in the silicon slag.Impurities in silicon slag exist in two forms: reduced and unreduced. In industrial silicon, a flocculant composed of Na2O5~50%, SiO250~95% or Na2O5~50%, SiO250~95%, MgO and CaO is added to industrial silicon. With 35% flux, the melting point of the slag can be reduced from the original 1450 to about 1480 and then down to about 1000. It can also reduce th

The best way to improve the life of graphite boards to use antioxidant solution

The best way to improve the life of the graphite board is the success of anti -oxidation solution with the development of graphite boards. After delivery and use in many industries, there will still be more and more technical advantages and characteristics in many levels. Among them, the continuous improvement of processing work capacity will still be unusual in the advantages and performance levels of its talents. In more cases, they all feel that their technical standards will still be higher and higher. The selection generated will still have a difference.Therefore, what are the aspects of their technical advantages? Below my graphite board manufacturer in Shanxi Province will introduce the old iron in detail:The antioxidant solution has good performance. Generally speaking, in the whole process of the construction of graphite board projects, the provisions of anti -oxidation levels are getting higher and higher, especially as a wall insulation layer. The advantage can be seen that

When cleaning graphite molds, there are still many precautions to understand

Systematic graphite mold maintenance is based on the coherence of maintenance needs and maintenance operations. In order to achieve the "cost -effectiveness" goal, cleaning graphite molds must be paid attention to. Formulate a detailed graphite mold cleaning plan. When cleaning the different parts of the graphite mold, such as cleaning inside the press, wiping along the edge, routine cleaning, and the main part of the cleaning, the cleaning operation method is also different. After the graphite mold runs a certain period of time and is tested by electroplating, magnetic labeling, and graphite molds in the ventilation holes and non -open air holes, the technical staff can determine the procedure and frequency of the graphite mold cleaning through the appearance inspection. Essence Therefore, it is very important to understand the cycle of the safe operation of graphite mold and the observation report of the accumulation and wear of residual objects inside the graphite mold. Based on gr

The relationship between graphene and scales graphite

Graphene is stripped from scales graphite materials, composed of two -dimensional crystals composed of carbon atoms, with a thickness of only one layer. Because graphene has excellent performance in optics, electrical, and mechanics. Is graphite related to graphene? Let me analyze the relationship between scales graphite and graphene with everyone:1. The method of extraction of graphene mass production is not obtained from scales graphite, but from carbon -containing gas such as methane and acetylene. Although the word graphite is used in the name, the production of graphene is not mainly from scales graphite. On the contrary, it is obtained from carbon -containing gas such as methane and acetylene. Even the current research method is extracted from the planting plant tree. Now there is a method for extracting graphene from the tea tree.2, scales graphite contains millions of graphene. Graphene is actually in nature. If the relationship between graphene and scales graphite is mentione
