可膨胀石墨 (expandable graphite)
产品简介:
        天然鳞片石墨经化学方法处理,可以使其形成石墨层间化合物,经高温处理,使之急速分解再次发生膨胀,体积可增至原来的100 ~ 400倍,便是可膨胀石墨。可膨胀石墨又称柔性石墨或者酸化石墨。
        性质:具有良好的可膨胀性,疏松多孔,隔氧条件下耐温范围较宽,可在-200~3000℃之间,在高温、高压或辐射条件下化学性质稳定。
        用途:可做密封材料,阻燃材料,吸附材料,医疗、膨胀蠕虫粉末可以用于锂电池材料。
 
Product profile:
Natural flake graphite by chemical treatment, it can be formed into graphite interlayer compound, after high temperature treatment, rapid decomposition and expansion, the volume can be increased to 100 ~ 400 times of the original, is expandable graphite. Expandable graphite is also called flexible graphite or acidified graphite.
Properties: good expansibility, loose and porous, wide range of temperature resistance under oxygen insulation, between -200 ℃ and 3000℃, stable chemical properties under high temperature, high pressure or radiation.
Application: can be used as sealing material, flame retardant material, adsorption material, medical treatment, expansion worm powder can be used as lithium battery material.
