摘要
流延成型法是目前制备熔融碳酸盐燃料电池电极板的主要工艺。本文以环己酮 丁醇为溶剂 ,三油酸甘油酯为分散剂 ,以聚乙烯醇缩丁醛为粘结剂 ,聚乙烯乙二醇为增塑剂 ,通过球磨工艺制备了非水基羰基镍粉浆料。详细研究了分散剂用量 ,粘结剂 分散剂用量及其比例对镍粉浆料流变学性能的影响 ,并将浆料流延成型 ,研究了素坯的密度。
Tape casting is currently a powerful method for the manufacture of the electrode for molten carbonate fuel cells.In this work,the non\|aqueous carbonyl nickel slips were prepared by ball\|milling using Cyclohexanone\|butyl alcohol,Glycerol trioleate,Poly\|vinyl\|butyl and polyethylene glycol as the solvent,dispersant,binder and plasticizer,respectively.The rheological behaviors of the non\|aqueous carbonyl nickel slips were investigated by controlling the dispersant content,the total content of binder and plasticizer and the ratio of binder to plasticizer.The characteristics of the green tapes obtained by tape casting were studied in terms of densities,tensile strength and microstructure and related with the rheological properties of the slips.
