Graphite products, graphite products factory in Fujian

Fujian graphite products manufacturers Which one, metallurgical industry, mainly for refractory; 2, the foundry industry, used as a mold and rust paint; 3, the electrical industry for the production of carbon electrodes, carbon rod electrodes, batteries, system to be used as a TV picture tube of graphite milk paint, made of carbon products can be used in generators, motors, communications equipment, and many other aspects; 4, machinery industry, used as aircraft, ships, trains and other high speed machinery lubricants ; 5, the chemical industry, for the manufacture of a variety of corrosion-resistant containers and equipment; graphite due to its special structure, which has the following special properties: 1) High temperature resistance: the melting point of graphite is 3850 ± 50 ℃, boiling point of 4250 ℃, even by ultra-high temperature electric arc burning, weight loss is very small, the thermal expansion coefficient is small. Graphite strength with temperature increase and strengthen, at 2000 ℃, the graphite strength doubled. 2) electrical conductivity, thermal conductivity: the conductivity of graphite higher than the average non-metallic minerals a hundred times. Thermal conductivity than steel, iron, lead, metal materials. Thermal conductivity decreases with increasing temperature, even at very high temperatures, the graphite into a thermal insulator. Graphite graphite can be conductive because each carbon atom with other carbon atoms is formed only three covalent bonds, each carbon atom remain a free electron to transfer charge. 3) lubrication: lubrication performance depends on the size of the graphite flake graphite, the flake greater the smaller the coefficient of friction, lubrication, the better the performance. 4) Chemical stability: graphite at room temperature have a good chemical stability to acid, alkali and corrosion resistance to organic solvents. 5) plasticity: graphite, toughness, and can harvest a thin sheet. 6) thermal shock resistance: graphite used at room temperature can withstand dramatic changes in temperature will not destroy lives, when sudden changes in temperature, little change in the volume of graphite, will not crack. With the continuous development of science and technology, people graphite also developed many new applications. Flexible graphite products. Flexible graphite, also known as graphite, is the development of a new era of graphite products. US researchers successfully flexible graphite sealing material, to solve the problem of atomic valve leakage, followed by Germany, Japan, France began to develop and produce. This product is in addition to a natural graphite with the characteristics, but also has a special flexible and elastic. Accordingly, it is an ideal sealing material. Widely used in the petrochemical industry, atomic energy and so on. International market demand increased year by year.
