浅议铁元素对铝合金的影响

6系列铝合金是指通过浇铸、挤压而成的合金材料,具有良好的加工性能,在多个领域内得到广泛应用。在GIS产品中,6系列铝合金广泛应用于法兰、母线、管材和棒材等。不同铁元素含量在6系列铝合金的电学性能、机械性能的影响有着决定性的作用,如若处理不好,容易发生各类生产事故。6063铝合金通常用作导电产品的导体、触头等,是一种常见的铝合金材料。因此,有必要对6063铝合金中Fe元素的作用进行研究。

Terminal Effect of Drop Coalescence on Single Drop Mass Transfer Measurements and Its Minimization

For the mass transfer to single drops during the stage of steady buoyancy-driven motion, experimental measurement is complicated with the terminal effect of additional mass transfer during drop formation and coalescence at the drop collector. Analysis reveals that consistent operating conditions and experimental procedure are of critical significance for minimizing the terminal effect of drop coalescence on the accuracy of mass transfer measurements. The novel design of a totally-closed extraction column is proposed for this purpose, which guarantees that the volumetric rate of drop phase injection is exactly equal to that of withdrawal of drops. Tests in two extraction systems demonstrate that the experimental repeatability is improved greatly and the terminal effect of mass transfer during drop coalescence is brought well under control.
