Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Graphite electrode materials have the following six advantages

1、 Fast speed;Graphite discharge is 2-3 times faster than copper, and the material is not easily deformed. It has obvious advantages in the processing of thin ribbed electrodes. Copper has a softening point of around 1000 degrees, which is prone to deformation due to heating. The sublimation temperature of graphite is around 3650 degrees, and compared to copper, the thermal expansion coefficient of graphite material is only 1/30 of that of copper material;2、 Lightweight;The density of graphite is only 1/5 of that of copper. When using large electrodes for discharge machining, it can effectively reduce the burden on machine tools (EDM) and is more suitable for the application of large molds;3、 Low loss;Due to the presence of C atoms in spark oil, during discharge machining, high temperatures cause the C atoms in spark oil to decompose, forming a protective film on the surface of the graphite electrode, compensating for the loss of the graphite electrode;4、 No burrs;After the copper ele

Mechanical performance of expansion graphite at different temperatures

Expansion graphite has excellent chemical stability, heat resistance, sealing, self -lubricating, radiation resistance and high heat -conducting. It is widely used in industrial fields such as machinery, oil, chemical, metallurgy, aerospace, navigation, transportation, and transportation. It is an ideal advanced sealing material. The mechanical property of expanded graphite may be different at different temperatures.1. Within the temperature range of 400 degrees Celsius, the compressed elastic modulus, rebound rate, and compression rate of expansion graphite sealing materials are not significantly affected by the temperature, and the impact is not greatly affected.2. There are significant differences in the compression modulus, rebound rate, and compression rate of two samples made of different materials formulas and processes, and there are also appropriate differences in the compression strength.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

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr
