添加不同种类和含量的粘结剂, 通过冷压和热压方法, 结合炭化处理等不同工艺制备纳米碳管电极, 利用DC-5电池测试仪分析其在盐水中的充放电性能, 比较其电吸附比电容和等效电
阻, 发现当聚四氟乙烯(PTFE)的量为10%, 聚偏氟二乙烯(PVDF)的量为15%时, 电极可以冷压成型; 酚醛树脂(PR)的量为20%时, 电极可以热压成型, 随着粘结剂的增加, 电极在盐水中的电吸
附比电容降低, 等效电阻增大. 通过纳米碳管电极表面结构、形貌、亲水性及在盐水中电吸附电容和等效电阻的分析, 对其脱盐性能进行比较, 发现添加20%PR粘结剂热压成型电极经
炭化后, 其比表面积大, 内部孔隙丰富, 亲水性好, 在盐水中电吸附比电容大, 等效电阻小, 电吸附脱盐效果最为显著.

The Authors of this Article have done research on the cracking resistance of cold welding surfacing electrodes for blast furnace valves by adjusting the basicity of slag component, decreasing the hydrogen content and improving microstructure. The DF 2 Cold Welding Surfacing Electrodes prove to possess the following characters: 1) Excellent cracking resistance for surfacing alloys at normal temperature. 2) Excellent cracking resistance for repair welding and rewelding. 3) Excellent machinability for surfacing alloying.
