What are the characteristics of high pure scales graphite

High -pure scales graphite has good high temperature resistance, conductivity, high -pure graphite thermal conductivity, lubrication and chemical stability. Graphite manufacturers are widely used in metallurgical, machinery, environmental protection, chemical, fire, electronics, medicine, military, military, aerospace and other fields. Its status in the national economy is becoming more and more important, and it is an indispensable and important non -metal raw material for modern industry and high -tech development. Trace impurities have a great impact on the performance of graphite products. The higher the carbon content of high pure scales, the better its performance as a functional material.In order to analyze the trace impurities in high pure scales, the sample is usually grayed or wet to digest to remove carbon, dissolved ash with acid, and then determined the impurities in the solution. The grayization method does not need to dissolve gray with ultra -pure acid, avoiding the ri

Production process of electric carbon products

(1) Raw materials. The raw materials used in the production of electrochar products include carbon and graphite powder, metal powder, and binder.(2) Calcination. The calcination of petroleum coke used in the production of electric carbon products generally adopts electric calcination.(3) Ingredients. According to the performance requirements of electric carbon products, 4-5 solid powders are used as ingredients.(4) Material mixing. Mixing mainly uses dry mixer, dual axis stirring knife mixer, pressure mixer, and continuous mixer.(5) Rolling sheet. The paste prepared with coal tar pitch as the binder needs to be processed by rolling to ensure the uniformity of the mixing of various materials.(6) Grinding powder. Grind the kneaded material and rolled sheet material to obtain pressed powder.(7) Pressing. The forming of electric carbon product blanks is generally done by molding, and the forming equipment includes hydraulic presses and mechanical presses.(8) Heat treatment. Heat treatment

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

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

Analysis of the scope of application of industrial graphite in graphite products

Graphite products maintain the original chemical properties of flake graphite, namely acid resistance, corrosion resistance and physical properties, namely high temperature resistance 3000C and low temperature resistance 204C. Its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses weight in air at 450°C by 1 % , the rebound rate is 15-50% (density 1.1-1.5). It also has strong self-lubricating properties. Therefore, graphite products have been widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics and so on.Using the characteristics of graphite, people have deftly made different types of products according to the needs of engineering: such as high-purity graphite products, flexible graphite products, composite graphite products and so on.
