Precautions for using scales graphite?

Scales graphite is a product that is widely used in refractory materials and coatings in the metallurgical industry. Such as magnesium carbon bricks,。, etc. Now used as anticorrosive materials. Scales graphite is a rust -proof primer made of charcoal black, talc powder and oil, which has good chemical resistance and solvents. If you add chemical pigments such as zinc yellow to the formula, the rust -proof effect is better. During use, thermal shock resistance is strong and has good corrosion resistance. It is the main carbon raw material used in conjunction with refractory materials. It has an important impact on the brushing and high temperature intensity of carbon -binding materials such as magnesium carbon bricks. In the actual production process, carbon -combined refractory materials have strict requirements for the purity, gray, particle size and shape of the scales graphite. The structure and function of its high -temperature firing now depends to a large extent on the moisture

The balance of graphite mineral exploitation and environmental protection

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

Graphite crucibles have good thermal conductivity and high temperature resistance

Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance for rapid heating and cooling. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability.But the following points should be noted:1. To avoid damage to the graphite crucible caused by impact or falling from a height. Be careful when using, handle with care, and take a look at the surrounding environment.2. The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame.3. Prevent strong corrosive flames from directly spraying the sides and bottom of the crucible.4. Before use, it is necessary to heat bake and dry

The artificial synthesis process and equipment application of scales graphite

At present, the production process of scales graphite is to produce graphite products through the production of natural graphite ore through the production, ball grinding, and flotation, and provide artificially synthetic scale graphite production technology and equipment. Using this device, the grinding graphite particles can be reinstated into large -shaped graphite to improve the utilization rate of graphite. The following editor introduces the artificial synthesis process and equipment application of scales in detail:This device has two relatively rotating ring rules semi -round tanks, or two irregular semi -circular grooves that can be relatively rotated, one of which is fixed as a fixed ring groove, and the feed pores are engraved on the fixed ring groove; The power connection allows the power to drive it to rotate. It is a cycle groove, engraved with the material outlet, and the gap between the fixed ring groove and the mobile ring groove can be adjusted; when the two ring groo

The application of scales graphite in the casting industry

Scales graphite is widely used in industry, especially the casting industry. In the production process of the casting industry, the casting process is carried out at high temperature environments. In order to prevent castings from deforming or broken at high temperatures, special casting scales need to be added to add cast materials and add casting materials. After the scale graphite, it can resist high temperature to ensure the quality of the casting. The following editor of graphite manufacturers will introduce the important application of scales graphite in the casting industry:There are many specifications for casting scales for castings, 600 meters ~ 800 mesh, 1200 mesh and other specifications for casting dedicated graphite. In different casting production fields, special casting scales of different mesters need to be used. Graphite helps the product to complete faster and better, and improve the quality of the casting products. Therefore, the scale graphite of the cast plant is

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.

Prevention and gray removal of graphite production and processing workshop

The anti -pollution -proof of graphite production and processing workshop is stable in the physical properties of ash graphite and no organic chemical corrosion. Therefore, the removal of the ash in the workshop does not need to consider anti -virus and corrosion resistance, mainly to reduce the concentration value of smoke and dust in the air and collect tiny smoke.First, to ensure the sealing of graphite production and processing workshop, and prevent environmental pollution from smoke and dust. Graphite production and processing workshop air has graphite smoke dust. Graphite smoke should be collected and purified according to the dust removal equipment before removing the workshop.In the secondary, graphite production and processing should be based on the concentration value of the smoke and dust caused by the system. Different CNC lathes, different concentrations of production and processing processes are different. For example, the concentration value of the smoke and dust concen
