可膨胀石墨
主要用途 规格型号 技术指标

       采用优质大鳞片石墨为原料,经特殊化学处理或电化学处理而得到的一种石墨产品。它遇高温可瞬间膨胀,膨胀倍数可达150-500倍,由片状变为蠕虫状,从而结构疏松,多孔而弯曲,比表面积大,表面能高,吸附力强。蠕虫状石墨之间可自行嵌合,这样增加了它的柔软性、回弹性和可加工性,是生产柔性石墨板材、各种密封件的优质材料。膨胀石墨除了具备天然石墨本身的耐冷热、耐腐蚀、自润滑等优良性能以外,还具有天然石墨所没有的柔软、压缩回弹性、吸附性、生态环境协调性、生物相容性、耐辐射性等特性。还可用于润滑剂添加剂、冶金工业的保温添加剂、消防的添加料、电池吸附材料、低温可膨胀石墨的阻燃材料等。
        Expandable graphite is a kind of graphite product which takes natural flake graphite as raw material and is treated by chemical or electro-chemical technology. When it is under high temperature, it can expand 150-400 times in volume instantaneously, flake graphite becomes vermiform graphite which is loose in structure, porous, curved, with large surface area, high surface energy and strong absorptive power. The vermiform graphite pieces can be inlaid by themselves. In this way, its flexibility, resilience and plasticity are increased. It is a high-quality material for making flexible graphite sheets and various sealing components. Except has the excellent properties such as cold and heat resistance, corrosion resistance, self lubrication, etc, expandable graphite also has the properties such as softness, compression resilience, adsorption, ecological environment compatibility, bio compatibility and radiation resistance and other characteristics It can also be used for lubricant additives, metallurgical industry insulation additives, fire additives, battery adsorption materials, low-temperature expandable graphite flame retardant materials, etc.
