一、前言 不透性石墨在化工行业中的应用日益广泛,它具有耐腐蚀、易加工、导热性能好等特点,必将成为一种有开发前景的材料。由于目前在我国仍大都采取单向挤压成型,这使性能不够稳定,各批材料的性能往往相差颇大,需逐批加以测定,故工作量很大,加之材料脆性较大,直至断裂也没有明显的变形,因此寻求一种行之有效而又操作方便的测定方法将是很有意义的。本文推荐一种弹性摸量E和泊松比μ的测定方法,供同行们参考。
First, the impermeability Graphite in the chemical industry is widely used, it has corrosion-resistant, easy processing, good thermal conductivity and other characteristics, will become a development prospects of the material. Due to the current one-way extrusion molding in most of our country, which makes the performance not stable enough, the performance of each batch of materials often quite different, to be determined by the batch, so the workload is large, combined with the larger the material brittle, until the fracture is also No obvious deformation, so to find an effective and easy to operate the determination of the method will be of great significance. In this paper, a method to determine the elastic modulus E and Poisson’s ratio μ is recommended for reference.
