Flake graphite powder is natural crystalline graphite, which is shaped like fish phosphorus, belongs to the hexagonal crystal system, and has a layered structure. It has good high temperature resistance, electrical conductivity, thermal conductivity, lubrication, plasticity, acid and alkali resistance.
Natural Flake Graphite Properties:
Flake graphite has complete crystallization, thin flakes, good toughness, and excellent physical and chemical properties. It has good thermal conductivity, electrical conductivity, thermal shock resistance, and corrosion resistance.
Graphite powder has good electrical conductivity. Although it cannot be compared with aluminum, iron, copper and other metals, its electrical conductivity is quite high compared with other common materials. It is three times that of carbon steel and five times that of stainless steel, and 100 times higher than other non-metallic materials.
Natural flake graphite powder has good lubricity. The coefficient of friction of graphite powder can be less than 0.1, and the lubrication performance varies with the size of the flake. The larger the flake, the smaller the friction correlation coefficient and the better the performance of the lubricating material.
Natural flake graphite has good thermal shock resistance. When the temperature changes suddenly, its thermal expansion coefficient is small, and its good thermal stability prevents graphite-related products from cracking.
Natural Flake Graphite Applications:
Refractory
Flake graphite is widely used in advanced refractories and coatings in the metallurgical industry. After intensive processing of flake graphite, graphite emulsion can be produced, which can be used in lubricants, mold release agents, wire drawing agents, conductive coatings, etc.
Coating
As a functional filler of coatings, flake graphite is mainly used for anti-corrosion coatings, fire-resistant coatings and conductive coatings.
As an anti-corrosion material, it is made of carbon black, talcum powder and oil, etc., and has good corrosion resistance to chemicals and solvents; if chemical pigments such as zinc yellow are added to the formulation, the anti-rust effect is better .
Expandable graphite is used as a fireproof filler, which is a kind of graphite interlaminar compound obtained by chemical or electrochemical treatment with natural graphite flakes as raw materials.
Flake graphite can be directly used as a carbon-based conductive filler, or it can be made into a composite conductive filler for conductive coatings.
