Ceramic Raschig rings of φ6×6×1mm have been used in industrical emulsification columns for years for their higher efficiency, lower cost and corrosion resistance. But the lower capacity and ease of breaking in the packing process has limited the application. Several new types of metal rings with "window" are investigated and manufactured by the authors. Compared with ceramic Raschig rings, the production rate of the new packing increases the production rate significantly with a slightly higher separation...

φ6×6×1毫米拉西瓷环的乳化塔(又名充液填料塔),自开发成功后应用于工业生产已经有好多年了。它具有效率高、成本低、耐腐蚀等优点,但处理能力小、在装卸过程中易碎等缺点限制了它的进一步应用。本文通过对乳化塔填料的传质作用及其结构进行分析,提出了金属开窗环结构的填料,以期改进填料特性。生产实践证明,这种金属开窗环填料与原用同样外形尺寸的拉西环填科相比,不仅生产量有较大辐度的提高而且分离效率也略有增长。

Although aluminide coatings have good oxidation resistant properties, their hot corrosion resistance is not satisfactory. It is thought that Cr-Al coatings may improve the high temperature corrosion resistance over that of aluminide coatings. Is it possible to produce a Cr-Al coating by a single step pack process? How good is the corrosion resistance of the Cr-Al coatings? These problems are discussed in this article. The experimental results show that it is difficult to obtain Cr-Al coatings on pure Ni...

Although aluminide coatings have good oxidation resistant properties, their hot corrosion resistance is not satisfactory. It is thought that Cr-Al coatings may improve the high temperature corrosion resistance over that of aluminide coatings. Is it possible to produce a Cr-Al coating by a single step pack process? How good is the corrosion resistance of the Cr-Al coatings? These problems are discussed in this article. The experimental results show that it is difficult to obtain Cr-Al coatings on pure Ni by a single step pack cemenation process because aluminium deposited on nickle specimen and chromium powder reduces activity of chromium greatly, thereby hampering the chrominizing process. It is possible to form Cr-Al coatings by two-step pack processes. However the order of coating steps is very essential: a useful Cr-Al coating which can resist oxidation and hot corrosion can be produced by means of aluminizing after chrominizing, but an uncompact Cr-Al coating which contains many holes and doos not well resist oxidation and hot corrosion well be formed by chominizing.

本文作者采用粉末包装法制备Cr-Al二元涂层,对Cr-Al二元涂层的制备以及涂层的高温腐蚀性能进行了研究。实验结果表明,在纯Ni上制备Cr含量较高的Cr-Al共渗涂层是困难的,纯Ni上Cr-Al共渗时,Al会同时沉积到纯Ni试样和Cr粉表面上,由于Cr粉表而上铝涂层的形成,大大降低丁Cr的活度,从而抑制了Ni上渗Cr的过程;然而,在纯Ni上用二步法制备Cr-Al二元涂层是可行的,先渗Cr后渗Al能产生理想的Cr-Al二元涂层,涂层具有良好的抗高温氧化和抗热腐蚀性能;而先渗Al后渗Cr则产生有孔洞的Cr-Al二元涂层,涂层的抗高温腐蚀性能很差。
