中文摘要: |
采用粒度测试、SEM 和XRD等分析手段,系统研究了球磨时间和过程控制剂对制备超细镍粉的影响。结果表明:随着球磨时间的延长,镍粉的粒度在初期减小较快,后期的减小趋于平缓;过程控制剂KH-570的加入能有效加快超细镍粉的细化,提高分散性能、片状化程度和表面的洁净度。加入过程控制剂KH-570,球磨36h,能获得粒度为5.76μm 的高纯镍粉。 |
英文摘要: |
The influences of milling time and process control agents on the preparation of ultrafine nickel powder were studied systematically by granularity test, SEM and XRD. The results show that: with increasing milling time, the nickel powder particle size decreases rapidly at first and then the particle size changes slightly, the nickel powder can milling effectively by adding process control agent KH-570, the dispersion properties, sheet extent and the surface cleanliness are also improved. Milling 36 h the nickel powder with the process control agent KH-570 can obtain 5.76 μm high-purity nickel powder. |
