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.
After intensive processing flake graphite can be made into graphite oil, which can then be used in lubricants and mold release agents as well as wire drawing agents and conductive coatings. 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 excellent resistance to chemicals, solvents, and if chemical pigments, such as zinc yellow, are added to it, it will protect against 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 a raw material, is also used. Expandable graphite expands quickly 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 a high surface energy.
Flake graphite may be used to make conductive coatings or as a carbon-based filler. Due to the high volume of graphite flake added, the coating’s performance and ease of application will be reduced. We have taken measures to increase the conductivity of graphite, and decrease the amount of graphite flake added.
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.
