Application of Flake graphite
- Jul 30, 2016 -

Flake graphite is widely used in metallurgical industry of advanced refractory materials coatings. Magnesia carbon bricks, crucibles and others. Military industrial explosive material stabilizers, light industry, smelting industry growth rate of desulfurization agent pencil industrial carbon brushes, electrical industry, battery electrodes, catalysts for fertilizer industry. After extensive processing of scale graphite, but also produces graphite, used lubricants, mould release agents, drawing, conductive coating and so on. Can also produce expanded graphite and flexible graphite products for raw materials, such as flexible graphite and flexible graphite sealing composite material products.

Paint

Flake graphite as functional filler for paints mainly used in anti-corrosion paints, fire retardant paint, and conductive coatings.

As corrosion-resistant materials, and carbon black, talcum powder and oil made of rust-proof primer has good resistance to chemicals and solvents corrosion if recipe added chemicals such as zinc yellow pigments, rust better.

Expandable graphite is used for fireproofing filler, it is natural graphite flakes as raw material, obtained by chemical or electrochemical processing of graphite intercalation compounds. Expandable graphite in the heating conditions, swell in size (up to a maximum of 300 times) choked the flame, producing swelling, reaching isolated flame, delay or interrupt the spread of flame and does not burn, good flexibility, high surface energy, carbonized layer strength. But expansion of the amount of volume and to select appropriate. Tests showed that expansion multiple of 150um particles, 30%, 5% the most appropriate.
