Characteristics of Mechanical Processing of Carbon Materials

(1) The organizational structure of carbon materials is formed by the preparation of carbon solid aggregate particles and powder raw materials through a series of production processes, so its cutting is composed of a certain number of particles and dust. The large amount of carbon dust generated during the cutting process not only pollutes the operating environment and affects the health of operators, but also the silicon carbide impurities contained in graphite dust can cause certain wear and tear on machine tool components. Therefore, efficient ventilation and dust removal equipment must be installed in the mechanical processing workshop of carbon materials.(2) Carbon material is a heterogeneous and brittle material, with a considerable range of hardness fluctuations. Roasted carbon products have a high hardness, which makes processing more difficult. Graphite products have a low hardness, making them easy to cut and process. The surface roughness of products processed with carbon m

Scales graphite has the cause of lubrication and the conditions of use

Scales graphite has many high -quality characteristics, especially good lubrication, so that it is widely used in many fields. Why is the scales graphite good lubricating, and under what conditions are better lubricating performance? Graphite manufacturer Xiaobian will analyze in detail for you:1, scales graphite is lubricated.The scales graphite played its good lubrication when there is water vapor and air. The presence of water and air enables the surface of the scale graphite to absorb water and gas molecules, which increases the distance between the sliding solution and weakens their binding force. On the one hand, the adhesion is also provided by the free keys on the edge of the base surface of the scales. Because water and gas molecules occupy these free keys, the adhesion force is reduced. This is why the scales are lubricated.2, scales graphite lubricating conditions.Scale graphic can only have good lubrication only in the case of water and air. For example, in a thin high alt

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

Some related knowledge points of high pure graphite?

The applicable areas of high pure graphite include metallurgical, military, light industry, electrical battery industry, and fertilizer. It can be called high -purity graphite. In order to make more people familiar with it, here is some of the relevant knowledge points of Gao Chun graphite? I hope you can bring some better ones when you see it. Help.High -pure graphite is widely used in metallurgy, machinery, environmental protection, chemical, electronics, medicine, military, military and aerospace and other fields. Has high -purity, high -intensity graphite performance. In fact, the existence of graphite scales now makes graphite have excellent lubrication. Generally speaking, the larger the ordinary graphite scales, the better the lubricity. When we use it, we need to know that the graphite industry technology is still at a low level in the world. The products are mainly raw materials and initial processing products. Therefore, the high impurities of some products have limited its

The Application of Expandable Graphite

1. Sealing material: the raw material high carbon graphite is mixed with concentrated sulfuric acid and nitric acid for acidification treatment, heat treatment and then pressed into shape. The prepared flexible graphite is a new high-performance sealing material and a nano material grown in situ. Compared with traditional sealing materials such as asbestos rubber, it has good Compressibility, resilience, self-adhesion, low density and other excellent properties, and can be used at high temperature It has been used for a long time under harsh working conditions such as high corrosion. Graphite plates and sealing elements made of it are widely used in aerospace, machinery, electronics, nuclear energy, petrochemical, electric power, shipbuilding, smelting and other industries.
