Natural flake graphite
Natural crystalline graphite has a shape similar to fish phosphorus. It belongs to the hexagonal system and has layers. It exhibits good resistance to heat, electrical conductivity, heat conduction and lubrication.
Flake graphite can be found in complete crystals or thin flakes. It has good physical and chemical properties and excellent thermal conductivity.
Natural Flake Graphite Application
Flake graphite is used widely in advanced refractories in the metalurgical industry. Magnesia carbon bricks, crucibles and others. Stabilizers in the military industry for pyrotechnics, desulfurization accelerators, pencil leads, and carbon brushes for industry.
Graphite Emulsion can be made from flake graphite after it has been processed. It can be used in lubricants as well as mold release agents and wire drawing agents. It can also produce expanded graphite which is used in flexible graphite products like flexible graphite seals, flexible graphite-composite products, and so on.
Flake graphite is used primarily as a functional filler for coatings.
Anti-corrosion material: The anti-rust primer is made of natural phosphorous flake Graphite and carbon Black, talcum Powder, and oil. It has good resistance to solvents and chemicals. Chemical pigments like zinc yellow can be added to the formulation to prevent rust.
Natural phosphorous flake graphite can be used as a fireproof material. Expandable graphite, a form of graphite interlaminar compound that has been produced by electrochemical or chemical treatment of natural graphiteflakes as raw material, is also used. Expandable graphite expands rapidly under heating (up to 300x), which suffocates a flame. It also generates expansions which can help isolate the flame or stop it from spreading. It is incombustible, flexible, strong, and has high surface energie.
Flake graphite may be used to make conductive coatings or as a carbon-based filler. Due to the large number of graphite flake added, the coating’s performance and ease of application will be reduced. Therefore, we take measures to increase the conductivity of graphite as well as reduce the amount added graphite flakes.
This short-cut fiber material is a solvent-free thick films conductive coating with functional filleders. It has characteristics such as anti-corrosive medium penetration and low curing residue stress. It is also resistant to matrix deformation and cracking. The coating can be used for long-term static electricity transmission. The inner wall of crude oil storage tank’s crude oil storage tanks can be coated with natural phosphorous flake graphite.
According to reports, electroless plating technology can be used to coat graphite dust with metals like nickel, silver, and copper. This allows for the preparation of composite conductive fillers. They are used in conductive coateds in an amount 30%. This not only improves conductivity, but also provides corrosion resistance.
