摘要： Corrosion inhibiting pigments are obtained by partial reduction of a hexavalent chromium compound in aqueous solution obtaining a reaction product containing 5 to 95% of the chromium in lower valent state. In the aqueous reaction mixture there is incorporated a water-soluble or water-dispersible polymeric material capable of reacting with chromate to form an insoluble product therewith and the obtained mixture evaporated to dryness under controlled conditions, followed by subdividing the obtained dry mass to suitable size.

摘要： This invention provides for an improvement in slurry transport systems, especially coal slurry lines. Instead of the usual use of fresh water resources which, in some geographic areas, are scarce for slurry transport, concentrated brine is used which is prepared from abundant salt water resources. Because of the higher density of this concentrated brine, it is a superior carrier of pulverized material. It dimishes the separation and settling tendency of slurry components during transport and particularly during shutdown. Other advantages in the use of concentrated brine include: freezing point depression which permits ease of transport during winter and at lower temperatures; dust suppression of stored coal; avoidance of spontaneous combustion of stored coal; inhibit freeze packing of dewatered pipeline coal; and diminished extent of corrosion in ferrous metal pipelines as compared to that which might occur with lower concentration brines. Important in the economy of the process is that the concentrated brine can be recycled. An inexpensive method for producing the concentrated brine is given.
摘要翻译：本发明提供了浆料输送系统，特别是煤浆管线的改进。而不是通常使用淡水资源，在某些地理区域稀缺的泥浆运输，使用浓缩的盐水，这是由丰富的盐水资源制成的。由于该浓缩盐水的密度较高，因此它是粉碎材料的优良载体。它在运输过程中特别是在关闭期间降低了浆料组分的分离和沉降趋势。使用浓缩盐水的其他优点包括：在冬季和较低温度下易于运输的凝固点凹陷; 贮存煤粉尘抑制; 避免储存煤的自燃; 抑制脱水管道煤的冷冻包装; 并且与较低浓度的盐水可能发生的情况相比，黑色金属管道的腐蚀程度减小。经济上重要的是浓缩的盐水可以回收利用。给出了生产浓缩盐水的廉价方法。

摘要： A chromium chromate complex, obtained by partial reduction of chromic acid in aqueous media with an organic reducing agent, is converted to pigment form by evaporating the resulting aqueous composition to dryness and sub-dividing the obtained solid mass to suitable size. The obtained pigment, with or without intimately associated extenders, incorporated in a conventional vehicle, serves as a corrosion inhibitor in metal coating compositions.
