过滤用金属多孔材料力学性能研究进展

Research progress on mechanical properties of porous metal materials used for filtration

  • 摘要: 金属多孔材料作为功能与结构兼具的一类新型材料,已被广泛应用于吸声、吸能、流体分布、换热、催化、过滤分离等领域,其中在过滤分离领域应用最为广泛。金属多孔材料在石油石化、精细化工、煤化工等领域可以实现不同流体的液–固、气–固过滤分离,不同领域对所用金属多孔材料的材质及力学性能要求也不尽相同。过滤用金属多孔材料的制备工艺已相对成熟,但对其耐蚀性能及力学性能的表征研究较少,金属过滤元件的力学性能及耐腐蚀性能将直接关系到该类材料的使用效果和寿命。本文总结了近几年过滤用金属多孔材料力学性能及耐腐蚀行为的研究进展,探讨了该类材料在腐蚀与力学行为中存在的问题,最后展望了过滤用金属多孔材料的发展方向。

     

    Abstract: As a new type of functional and structural material, the porous metal materials have been widely used in the fields of sound absorption, energy absorption, fluid distribution, heat exchange, catalysis, filtration, and separation, which are the most widely used in the field of filtration and separation. Porous metal materials can achieve the liquid−solid and gas−solid filtration separation for the different fluids in the fields of petroleum and petrochemical, fine chemical, coal chemical, and other fields, and the requirements for the materials and mechanical properties of the porous metal materials used in the different fields are also different. The preparation process of porous metal materials used for filtration is relatively mature, but there is little investigation on the corrosion resistance and mechanical properties of the porous metal materials, which will directly affect the use effect and life of such materials. The research progress on the mechanical properties and corrosion resistance of the porous metal materials used for filtration in recent years was briefly reviewed in this paper, and the existing problems in the corrosion and mechanical behavior of such materials were discussed. Finally, the research direction of the porous metal materials used for filtration was prospected.
