Expanded graphite (after expansion of expandable graphite is a high quality natural flake graphite used specially modified handle and a flexible graphite products obtained by transient high temperatures, the scales into a worm-like, is an ideal new sealing material. I produced The expanded graphite worm distribution after expansion, as the late production of quality products to provide a guarantee.
Graphite. Graphite is a carbon crystal, is a non-metallic materials, graphite, he thermal conductivity and electrical conductivity is very high, and its electrical conductivity is 4 times higher than stainless steel, non-metallic than 100 times higher. Its thermal conductivity is not only more than steel, iron, lead, metals, and thermal conductivity decreased with increasing temperature, and general metal materials that are different at very high temperatures, graphite and even tends to the adiabatic state. Therefore, in the ultra-high temperature graphite insulation performance is very reliable. Graphite has good lubricity and plasticity, chemical stability, to acid, alkali, corrosion resistance to organic solvents.
Graphite through screening and re-processing is used in the graphite industry.
Graphite is a carbon crystal, is a non-metallic materials, color silver gray, soft, metallic luster. Mohs hardness of 1 to 2, the proportion of 2.2 to 2.3, its weight is generally from 1.5 to 1.8.
Graphite, high melting point, the vacuum tends to 3000oC melting when the state began to soften, to 3600oC began when the evaporation of graphite sublimation, the general strength of materials under high temperature gradually decreased, while the graphite in the heat to 2000oC, rather than the room temperature strength to improve doubled, but poor oxidation resistance of graphite as the temperature increased oxidation rate increased.
Graphite thermal conductivity and electrical conductivity is very high, and its electrical conductivity is 4 times higher than stainless steel, carbon steel than 2 times higher than the general non-metallic 100-fold. Its thermal conductivity is not only more than steel, iron, lead, metals, and thermal conductivity decreased with increasing temperature, and general metal materials that are different at very high temperatures, graphite and even tends to the adiabatic state. Because of ratio, in the ultra-high temperature conditions, the graphite insulation performance is very reliable.
Specifications Specifications Graphite Graphite Fixed carbon Ash Moisture (various size) carbon graphite (various size) low-carbon and other specifications shall be formulated separately.
Expanded graphite is a high quality natural flake graphite used specially modified handle and get a flexible graphite products, is an ideal new sealing material, due to its chemical stability, acid, alkali and other properties, is widely used in petroleum, chemical, electrical, aerospace, automotive, marine and instrumentation industries such as static and dynamic seals. Also be used for metallurgical industry, the new flux, heating agent. Graphite sealing industry is the most commonly used as a raw material.
