  An aqueous solution composition of a strong alkali and a nonionic surface active agent comprising: (a) a strong alkali, (b) a nonionic surface active agent having an HLB value of 3 - 18, and, as a solubilizing agent, (c) a specific type of carboxylic acid is disclosed. The composition contains a strong alkali and a nonionic surface active agent having an HLB value usually of 3 - 18 at high concentrations and stably and is homogeneous and transparent. Thus, it is useful for a variety of applications requiring both alkalinity and detergency, for example, as wettability promoting agents of glass, fiber, metal, and earthenware surfaces as well as various toiletry products.

  本发明公开了一种强碱和非离子表面活性剂的水溶液组合物，其中包括：(a) 强碱，(b) HLB 值为 3 - 18 的非离子表面活性剂，以及作为增溶剂的 (c) 特定类型的羧酸。该组合物含有强碱和 HLB 值通常为 3 - 18 的非离子表面活性剂，浓度高且稳定，均匀透明。因此，它适用于各种既需要碱性又需要去污力的应用，例如用作玻璃、纤维、金属和陶器表面以及各种洗浴用品的润湿促进剂。

  The rolling bearing of the present invention is lubricated with a lubricant composition which contains a fatty acid metal salt, a dithiocarbamic acid metal salt, a phosphorous additive, and a basic additive, and which has a total acid number of 3.7 mgKOH/g or more. The rolling bearing makes it possible to further improve anti-fretting performance, and to reduce a decrease in anti-fretting property even when used in an environment in which fluorine grease penetrates into the bearing in which urea grease is used.

  本发明的滚动轴承使用一种润滑剂组合物进行润滑，该组合物含有脂肪酸金属盐、二硫代氨基甲酸金属盐、磷添加剂和碱性添加剂，其总酸值大于或等于 3.7 mgKOH/g。这种滚动轴承能够进一步提高抗摩擦性能，即使在氟润滑脂渗入使用尿素润滑脂的轴承的环境中使用，也能减少抗摩擦性能的下降。
