Graphite flake with a purity of 92% (carbon content). Is packed in 25kg bags. Grain size is measured based on the analysis of one sieve, by or under the wire.
graphite flake
flake graphite is a form of natural graphite, which is the result of metamorphism of carbon-rich organic matter. Has a highly ordered crystalline structure and a distinctive metallic gloss, therefore, is also known as graphite, silver or crystal. The basic properties of graphite are good thermal and electrical conductivity, low coefficient of thermal expansion, high chemical and thermal resistance, excellent lubricating properties. The nature of the spatial structure of graphite flake results in ease of breaking bonds between adjacent planes and creating a scaly structure, even at the highest fragmentation. Consequence of the layered structure is also a significant anisotropy of the properties of flake graphite. Hardness, strength and conductivity in a direction parallel to the axis of crystallite exceeds several times the value in a direction perpendicular to that axis.
Transport and storage
graphite patch are packaged in bags of 25 kg (or 15 kg of graphite MG), delivered in large polypropylene bags on a pallet after BigBags 1000 kg or 600 kg in the case micropowders. Packages are designed for mechanical handling and storage facilities at the same time protect and equipment from dust, graphite dust troublesome. The storage must be in a dry and ventilated place, protected from access by the fire. Packages have a clear indication as to the type of material and batch number, this is the basis for determining the composition, nature and destination of the goods.
graphite Applications:
first Casting
graphite flake GF 192 and GF -192 is used as a coating to create a separator pattern making and molding, where he also serves as a protective covering of refractory cast against the formation of external defects in the type of burns, penetration, and crusts. It is used in powder or water-based slurry or other fluids. There is also a great addition to molding and core increases their thermal resistance, ductility and the tendency to secrete lustrous carbon.
second Refractories
Patch size graphite type FG 192, FG 594 and FG 397 uses for the production of black refractories, crucibles, retorts, furnace lining elements. Addition of graphite plasticity and facilitates the formation of the mass, also increases the quality of finished products, improves their fire resistance, chemical resistance, greatly reduces friction and coefficient of thermal expansion.
third Special lubricants
For the production of lubricants in the form of pastes and suspensions of colloidal graphite is used drobnopłatkowe FG -394 and micronized powder MG 1599. Graphite powders can be economically equivalent to the addition of molybdenum disulfide and refined in the lithium grease, lime and bentonite mass increasing their stability at high temperatures. In most applications the addition of graphite reduces the friction coefficient, especially at high loads, and reducing risk in equipment exposed to shocks and overheating. The presence of graphite in lubricants ensures the maintenance of lubricating properties after long time operation, even after use and dry, grease and other components.
4th Antistatic coatings
Due to good electrical conductivity of aluminum, graphite is used as an effective pasywator loads of materials with anti-static properties. It is a proven component in the manufacture of carpets, curtains and foil explosion of mining, accessories for floors, conductive and antistatic coatings. For the production of these materials is most commonly used graphite-type FG or -394, with higher expectations, a mixture of -394 FG, FG 192 with the addition of chopped carbon fiber.
5th Friction linings and brake
the manufacture of brake linings and the type of graphite used: -192 and a FG FG -394. Addition of graphite for the friction material increases its thermal conductivity, wear resistance and rapid changes in temperature, the same positive effect on reliability, durability and longer brake lining life.
6th Other Applications
flake graphite is often used also for the manufacture of paints and coatings and refractory corrosion, impregnation sealing materials and insulation, coatings and separators forging, production of battery cores, electrodes and electrical accessories, the manufacture of plastics and composites, cemented carbides, cermets, explosives, in the laboratory.
