Advantages of Flake Graphite in the Chemical Industry

Flake graphite is a basic industrial raw material and plays a significant role in the chemical industry. The processing of flake graphite is also extremely strict. Lubrication, plasticity, and acid and alkali resistance.

Properties of flake graphite

(1) Corrosion resistance: flake graphite relies on its own superior performance, acid and alkali corrosion resistance is the fundamental reason for it to become anti-corrosion materials, as anti-corrosion materials, flake graphite and carbon black, talc, and oil are made of anti-rust Primer with good resistance to chemicals and solvents. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect is better. As one of the main materials of anti-corrosion coatings, flake graphite is an anti-corrosion coating made of epoxy resin, pigment, curing agent, auxiliary agent, solvent, etc., which has excellent adhesion and durability, corrosion resistance, and impact resistance. Water resistance, salt water resistance, oil resistance, acid, and alkali corrosion resistance, high content of solid flake graphite in anti-corrosion coatings, can be used as thick film coatings, good solvent resistance, a large amount of flake graphite in anti-corrosion coatings, shielding after film formation It has strong performance and can effectively prevent the penetration of corrosive media to achieve the purpose of isolation and rust prevention.

(2) Graphite catalysis: flake graphite catalyzes organic reaction conditions with mild conditions and high selectivity, and has broad application prospects in the field of catalytic synthesis. Flake graphite has the characteristics of layered structure, good thermal stability, and expansion properties, and allows foreign molecules to intercalate, making it useful as a catalyst for different types of organic reactions, which can be used in the substitution, addition, rearrangement, oxidation and reduction reactions, etc.

(3) Wear resistance function: When the flake graphite rubs against the metal, a graphite film is formed on the surface of the metal and the flake graphite, and its thickness and degree of orientation reach a certain value, that is, the flake graphite wears faster at the beginning. down to a constant value. The clean metal-graphite friction surface has a better orientation, smaller crystal film thickness, and greater adhesion. This friction surface can ensure that the wear rate and friction data are small until the end of the friction.

Processing of flake graphite

When the flake graphite is chemically treated, the chemical reaction is carried out simultaneously at the edge of the graphite wafer and in the middle of the layer. The purity requirements for flake graphite are very strict, and impurities are not allowed, otherwise, there will be lattice defects and dislocations, resulting in the expansion of the edge region and the increase of active points, which will accelerate the edge reaction, although it is conducive to the formation of edge compounds, it affects the formation of compounds. Moreover, it also destroys the layered lattice, making the lattice disordered and irregular, and then the speed and depth of the diffusion of chemical substances to the layers, and the formation of compounds in the deep layers are hindered and restricted, which will further affect the expansion.

The field of graphite consumption will gradually turn to strategic emerging industries such as a new generation of information technology, biology, high-end equipment manufacturing, new energy, and new materials. The proportion of traditional fields has gradually decreased, and the proportion of graphite demand in emerging industries has further increased. With the large-scale and intensive production and application of high-value-added products such as lithium-ion batteries (new energy vehicles) and fuel cells (new energy and new materials industry), the use of flake graphite will inevitably increase.

The Franli factory focuses on the production of flake graphite, The factory has a laboratory specializing in researching the properties of different types of graphite flakes. Compared with graphite flake processing experience, the quality of graphite flakes is relatively high. Provide raw materials with strong performance for various industries.
