鳞片石墨 High Purity Flake Graphite

 

鳞片石墨
鳞片石墨也叫天然晶质石墨,其形似鱼磷状,故称为鳞片石墨,属六方晶系,呈层状结构,具有良好的耐高温、导电、导热、润滑、可塑及耐酸碱等性能。鳞片石墨结晶完整。片薄且韧性好。物理化学性能优异,具有良好的耐温性、自润滑性、热传导性、导电性、抗热震性、耐腐蚀性等性能。

Flake Graphite
Flake graphite is also called natural crystalline graphite, in the shape of fish phosphorusshape, thus called the flake graphite,belong to hexagonal crystalsystem layered structure,withoutstanding performance of high temperature-resistance, electrical and thermal conductivity,lubrication,plasticity, and acid and alkali resistance.Flake graphite crystallization perfect.Thin film and good toughness. Excellent physical and chemical properties, with good temperature-resistance, self lubrication, thermal conductivity,electrical conductivity, thermal shock resistance, corrosion-resistance etc.

鳞片石墨分类
鳞片石墨按含碳量的高低分类: 如含碳量≥ 99.9% 为高纯石墨;含碳量在94-99.9% 之间为高碳石墨;含碳量在80-94% 为中碳石墨;含碳量在50-80% 之间为低碳石墨。
Flake Graphite Grades
Flake graphite is classified according to the level of carbon content:such as the carbon content in 99.99-99.9% called high purity graphite;content between 99-94% called high carbon graphite; content between93-80% called middle carbon graphite; content between 75-50%called low carbon graphite.

主要用途
鳞片石墨广泛用于治金工业的高级耐火材料与涂料。如镁碳砖、坩埚等。军事工业火工材料安定剂、治炼工业脱硫增速剂、轻工业的铅笔芯、电气工业的碳刷、电池工业的电极、化肥工业的催化剂等。鳞片石墨经过深入加工,又可以生产出石墨乳,用于润滑剂、脱模剂、拉丝剂、导电涂料等。还可以生产膨胀石墨,用于柔性石墨制品原料,如柔性石墨密封件及柔性石墨复材料制品等。

Main Applications
Flake graphite is widely used in high-grade refractory materials and coatings in metallurgical industry. Such asmagnesia carbon brick, crucible etc,explosive material stabilizer in military industrial, desulfurization accelerator in metallurgyindustry, pencil in light industry, carbon brush in electrical industry, electrode in battery industry, catalysator in fertilizerindustry. Graphite through deep processing, can produce graphite colloid, used as lubricants, mold discharging agent, drawingagent,conductive coating etc.. Beside,graphite can produce expansible graphite, flexible graphite products,such as flexiblegraphite sealing parts and flexible graphite materials product.complete Flake crystalline,thin film and excellent toughness.superior physical and chemical properties,with perfect performance of temperature tolerance, self lubricity, thermal conductivity,electrical conductivity, thermal shock resistance, corrosion-resistance.

负目石墨
负目石墨是筛下物通过率大于80% 的细粉石墨,一般常用的有-100 目、-200 目。我公司采用天然大鳞片石墨矿石为原料,负目石墨产品能够保持大鳞片的各项优良指标。
High Purity Graphite
High Purity Graphite refers to flake graphite fixed carbon content of greater than 99.9%, general acid-base method or high temperature method to achieve purification, when the fixed carbon content
requirements of 99.99% and above purity graphite is the basis high purity graphite.
