The process flow of carbon material production

The basic process of carbon material production includes: pre-treatment (pre crushing, calcination, or drying) of carbon raw materials, crushing, grinding, and screening grading of carbon raw materials, proportioning of carbon raw materials, addition of molten dehydrated binder and kneading, forming of paste after kneading, and roasting of formed green billets. In order to improve the density and strength of products, high-pressure impregnation and secondary roasting cycle densification treatment are carried out on the roasted billets, The graphitization of roasted products involves mechanical processing of carbon and graphite products.Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes?The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature

Preparation of ultra -fine graphite powder

Graphite powder is soft, black and gray; it is greasy and can pollute paper. The chemical properties of graphite powder are relatively stable at normal temperature, insoluble in water, dilute acid, dilute alkali and organic solvents; the material has high temperature resistance resistance, which can be used for refractory materials, conductive materials, and wear -resistan

What are the factors that affect scales graphite quality?

The quality of scales graphite determines the product quality of the processed scale graphite powder. The scales graphite resources are natural graphite of the light crystal, which is formed by deteriorating quality under the action of long -term geology. The scales graphite crystals are scales -shaped. The scale of the scales of scales graphite and the amount of carbon content is the key factor affecting the quality of scales. The following editors will take you to understand:As the basic processing raw materials of various graphite powder products, the quality of scales graphite is an important condition. According to scales graphite quality, various parameters, etc., scales can be processed into graphite products such as scales graphite, ultra -fine graphite powder, high pure graphite, nanim graphite, colloid graphite and other graphite products. The scale size of the scales graphite determines the lubrication performance of processed. The larger the scale graphite size, the better

The difference between flake graphite and expanded graphite

Flake graphite is a type of natural graphite that, after being extracted and purified, generally appears in the form of fish scales, hence it is called flake graphite. Expandable graphite refers to flake graphite that, after acid washing and intercalation treatment, expands by about 300 times compared to the previous graphite. It can be used as raw materials for coils and flexible graphite. Below, let me introduce in detail the differences between flake graphite and expandable graphite:1. The use of flake graphite is more extensive than that of expandable graphiteIn industrial production, flake graphite not only has the function of expandable graphite, but also has much better conductivity, thermal conductivity, smoothness, and so on than expandable graphite. So its practical use in industry is becoming increasingly widespread.2. The production processes of flake graphite and expandable graphite are differentFlake graphite is mainly made by mechanical damage and grinding. Expandable g

Factors affecting the quality of silicon carbide grinding powder

Silicon carbide is widely used in industry and plays an important role. Silicon carbide can also be used as an abrasive, so the quality of silicon carbide particles is particularly important. We want to test its quality, so how to test its quality?Before proceeding to the analysis, the first thing we need to understand is that the abrasive is not only composed of particles of one shape, but only depends on the percentage of that shape. When analyzing the shape of abrasive grains, it can also be seen that the edges of the abrasive grain surface have characteristics such as smoothness, sharpness, rounded corners, straight lines, serrations, and cracks.Impurities are often mixed into the grinding powder. One is the components contained in the abrasive grains themselves, which are mainly formed during the smelting of raw materials, such as iron oxide, silicon dioxide, chromium oxide, and sodium oxide. Another kind of impurity is dissociated between particles, mainly iron filings and dust

What should I pay attention to when applying graphite machinery and equipment

1. Be careful when transporting or hanging. Do not drag and drag it on the ground. Do not pry up or use a galvanized steel wire rope to be tied immediately. Essence2. After the total installation, when welding or oxygen cutting of the steel case, it should be ensured that the safety of graphite and hydraulic sealing should be ensured (water can be injected in the shell), otherwise graphite should be removed.3. When connecting the external flanges, it is not forcibly installed. When the foot bolts are tight, the symmetry is symmetrical.4. The export and export valve of the opening and closing machine equipment should be slow to prevent the significant impact of raw materials.5. The application of materials, temperature and work pressure in applications should be strictly strictly in accordance with the requirements of the design plan.6. For the electric heater, when driving, you should first pass the raw material and pass the vapor; when used as a cooling or cooler, you should first pa

Artificial graphite characteristics

Crystal structureNatural graphite: Crystal development is relatively complete, the graphization of scales graphite is more than 98%, and the graphitization degree of natural micro -crystal graphite is usually below 93%.Artificial graphite: The degree of crystal development depends on raw materials and thermal treatment temperature. Generally speaking, the higher the thermal treatment temperature, the higher the graphite. The artificial graphite produced by industrial production is usually less than 90%.Organizational structureNatural scale graphite: It is a single crystal, which is simpler in the tissue structure. There are only shortcomings in crystalline learning (such as defects, wrong positions, errors, etc.). The grains of natural micro -crystal graphite are small, the clutter between the grains is arranged, and there is a hole after the removal of impurities, which shows the same sex in the macro.Artificial Graphite: It can be regarded as a variety of materials, including graphi
