    • This invention relates to a general packing of expanded graphite and the process for production thereof. The packing mainly includes vermiform laminae of expanded graphite and auxiliary materials, which is characterized by the embedment of the auxiliary materials into the vermiform graphite laminae, the bonding of the auxiliary materials to the vermiform graphite laminae with organic adhesives. The process for producing of the packing comprises the treatment of graphite with strong acid to produce interlaminar compound followed by transient expansion of treated graphite to become vermiform and the combination of vermiform graphite laminae with the auxiliary materials to produce packing. Wherein the above mentioned vermiform laminae of expanded graphite are bonded to the auxiliary materials with organic adhesives, and the auxiliary materials are embedded between the vermiform laminae of expanded graphite.
    • 本发明涉及膨胀石墨的一般包装及其生产方法。 填料主要包括膨胀石墨和辅助材料的蠕虫层状,其特征在于将辅助材料嵌入蠕虫状石墨层,用有机粘合剂将辅助材料粘合到蠕石状石墨层。 填料的生产方法包括用强酸处理石墨以产生层间化合物,随后经处理的石墨瞬时膨胀成蠕形,并将蠕虫状石墨层与辅助材料组合以产生填料。 其中上述膨胀石墨的蠕虫状薄片用有机粘合剂粘合到辅助材料上,并且辅助材料嵌入在膨胀石墨的蠕变层之间。
