[目的]阴极辊的表面状态会影响电解铜箔的品质,抛磨处理能够令阴极辊保持较佳的表面状态。[方法]通过对日常生产中阴极辊抛磨参数的跟踪与铜箔性能的分析,探究了电解铜箔生产中阴极辊在线抛磨对铜箔粗糙度、拉伸强度、延伸率等性能的影响。[结果]适当提升抛磨刷的摆动频率,降低抛磨刷与阴极辊间的接触压力,增大阴极辊抛磨长度,以及使用小粒度的抛磨刷均能降低铜箔的粗糙度,提高铜箔的常温拉伸强度,减小铜箔纵向与横向延伸率的差异,提高产品合格率。[结论]控制好阴极辊的在线抛磨参数有助于获得品质良好的电解铜箔。 相似文献

Analyses of firings by the up‐and‐down method were employed to gain a better understanding of the influences of foil bridge width, foil thickness, flyer thickness, and barrel length on the sensitivity of exploding foil initiators. Characterization was performed via the mean threshold voltage. The results showed that the mean threshold voltage of exploding foil initiators was reduced by 16 % when the foil bridge width was reduced from 0.4 mm to 0.3 mm, which means that a reduced foil bridge width could decrease the mean threshold voltage of exploding foil initiators as suggested by theoretical analysis. The mean threshold voltage of exploding foil initiators was reduced by 20 % as the flyer thickness was decreased from 50 μm to 25 μm, which could be an efficient way to improve the sensitivity of exploding foil initiators. The flyer accelerated to over 90 % maximum velocity after flying 0.15 mm in a fine barrel, which revealed that exceeding a barrel length of 0.15 mm has little effect on the performance of exploding foil initiators. 相似文献

新型铝箔衬纸复合用酪蛋白胶的研制 总被引:2,自引:0,他引:2
介绍了一种以干酪素为主要原料研制的铝箔衬纸胶粘剂的配方、制备工艺及技术性能。采用氨水溶解干酪素,硼砂作交联剂。讨论了固含量、碱、交联剂、反应时间、反应温度等因素对胶粘剂的制备与性能的影响。结果表明:在氨水用量为2.5g,尿素22g,硼砂3.5g,反应温度为65℃左右时制得的酪蛋白胶性能最佳。尿素可提高胶的韧性,使胶粘剂形成胶膜,同时可降低胶粘度,增加胶的流动性。 相似文献

The purpose of this study is to explore the effect on capacitance features of the solid state high performance polypyrrole capacitor with the chemically synthesized aluminum foil. Atomic force microscope (AFM) was used to analyze the surface structure of the chemically synthesized aluminum foil for the experiment and distribution of polypyrrole on the surface of the foil was observed and analyzed through scanning electron microscope (SEM) and energy dispersive x-ray spectrometer (EDS). Finally, evaluation of electric performance was conducted so as to establish the parameters for the surface structure of the chemically synthesized foil with the best series capacitance features. 相似文献
