Advantages and disadvantages of high carbon graphite purification methods

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has a lower cost. This is a major advantage of the flotation method for purifying graphite. However, using flotation to purify graphite can only achieve a limited increase in its grade. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomer, but also is not conducive to protecting the large scale of graphite. Therefore, using flotation to further improve graphite grade is neither economical nor scientific. To obtain high carbon graphite with a carbon content of over 99%, chemical methods must be used to purify the graphite.（1） Chlorination roasting method. The low roasting temperature and low chlorine consumption of the chlorination roasting method significantly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after treatment with hydrofluoric acid, and t

Who is related to the wear resistance of graphite products?

Graphite sells various models and specifications of graphite rods, graphite columns, graphite particles, graphite powder, graphite bearings, and graphite tubes, including lubrication, high purity, conductivity, and wear resistance. We can process various shapes of graphite products according to customer requirements.Graphite products have been widely used in industrial machinery due to their wear resistance and lubrication effects. In actual industrial production processes, the oxidation resistance of graphite products has always been a concern of the graphite industry. So what is the relationship between the oxidation resistance of graphite products?It can be seen that the self-lubrication of graphite depends on the presence of air and water. As a lubricating material, the critical value of moisture in the working environment of graphite products is 5g/m3. If it falls below this value, the friction coefficient of graphite products will increase. At room temperature of 300-400 degrees

The use of graphite molds is diverse

1. Graphite molds can be used as conductive materials in industry. In this regard, when using electric arc furnaces or submerged arc furnaces to smelt various alloys, strong current will be introduced into the melting zone of the electric furnace through the electrodes of the graphite mold to generate an arc. At the same time, electrical energy will be converted into heat energy to increase the temperature, which can achieve the production conditions for smelting and reaction.2. Graphite molds can be used as corrosion-resistant structural materials in industry. Due to the excellent corrosion resistance of the raw materials in graphite molds, they are often used in stainless steel and other products.3. Graphite molds can be used as compression and casting molds in industry. Due to its relatively small coefficient of thermal expansion and good heat and cold resistance, it can be used as a mold for various glassware and can also save a large amount of metal.4. Graphite molds can be used

Introduction to the use of expansion graphite

The expansion graphite was discovered in the early 1960s. Many countries like to use it to study, so that many unexpected results can be achieved. The so -called expansion can be increased by more? That's right, more than double or even double! It is new carbon material! Many people don't know much about expansion graphite!Graphite crystals are two -way large -molecular layer -like structures. The C atom in each plane is combined with the C -C co -price bond, and the layer is combined with weaker Van Dehua.The layered structure of graphite is very typical. Each layer is a carbon atomic layer. The carbon atom in the layer is a strong covalent bond with SP2 hybrid orbit, that is, 1 2S electronics and 2 2P electronic hybridization, etc. The hybrid track of the price is located on the same plane and forms σ bonds each other, while the two unsteady 2P electrons are perpendicular to the plane to form a two -key π. This layered structure of graphite makes a certain gap between layers. Theref

Can scales graphite be used as non -metallic fillers

When the scale graphite is used as a fire -resistant filler, it is an expansion of graphite powder. It is a graphite layer of inter -graphite compound obtained by natural graphite scales as raw materials. Under heating conditions, the volume of expansion graphite expands sharply (can reach 300 times) to suffocate flames, forming expansion together, which can be isolated flames, delaying or interrupting the spread of flames, not burning, flexible, high surface energy, and good coach layer. However, the volume and dose of swollen should be appropriately selected. Tests show that the best dosage is 150 μM particles, 30%expansion rates and 5%. The editor of the graphite manufacturer below introduces whether the scale graphite can be used as a non -metal filler and analyzes:Graphite can be used directly as a carbon conductive filler or a composite conductive filler for conductive coatings. However, due to the large increase in scale graphite, the function of the coating will become fragile
