鱗片石墨 High Purity Flake Graphite

 

鱗片石墨
鱗片石墨也叫天然晶質石墨,其形似魚磷狀,故稱為鱗片石墨,屬六方晶系,呈層狀結構,具有良好的耐高溫、導電、導熱、潤滑、可塑及耐酸堿等性能。鱗片石墨結晶完整。片薄且韌性好。物理化學性能優異,具有良好的耐溫性、自潤滑性、熱傳導性、導電性、抗熱震性、耐腐蝕性等性能。

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.

鱗片石墨分類
鱗片石墨按含碳量的高低分類: 如含碳量≥ 99.9% 為高純石墨;含碳量在94-99.9% 之間為高碳石墨;含碳量在80-94% 為中碳石墨;含碳量在50-80% 之間為低碳石墨。
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
鱗片石墨廣泛用于治金工業的高級耐火材料與涂料。如鎂碳磚、坩堝等。軍事工業火工材料安定劑、治煉工業脫硫增速劑、輕工業的鉛筆芯、電氣工業的碳刷、電池工業的電極、化肥工業的催化劑等。鱗片石墨經過深入加工,又可以生產出石墨乳,用于潤滑劑、脫模劑、拉絲劑、導電涂料等。還可以生產膨脹石墨,用于柔性石墨制品原料,如柔性石墨密封件及柔性石墨復材料制品等。

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.

負目石墨
負目石墨是篩下物通過率大于80% 的細粉石墨,一般常用的有-100 目、-200 目。我公司采用天然大鱗片石墨礦石為原料,負目石墨產品能夠保持大鱗片的各項優良指標。
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.
