摘要： The invention relates to alkaline cleaners containing two components A and B, component A being a strongly alkaline solution comprising mostly alkali metal hydroxides and employed in an excess, component B being a concentrate comprising an aqueous silicic acid dispersion containing anionic, nonionic or amphoteric tensides, builder substances, stabilizers and optionally inorganic mineral acids, complexing agents and/or preservatives. Component B contains, as an active ingredient, adjusted to a pH in the range of from 1 to 11, a silicic acid dispersion obtained in situ by treating an alkali metal silicate solution with a mineral acid or a gas reacting acidically in aqueous solution. The dispersions also contain stabilizers, tensides and builder substances. If desired, additional agents conventionally contained in cleaning concentrates may also be added. The invention also relates to processes for preparing such cleaners by treating an alkali metal silicate solution with a mineral acid or a gas reacting acidically in aqueous solution and adding tensides, stabilizers and builder substances thereto.

摘要翻译： 本发明涉及含有两种组分A和B的碱性清洁剂，组分A是主要是碱金属氢氧化物并且过量使用的强碱溶液，组分B是包含含有阴离子，非离子或两性表面活性剂的含水硅酸分散体的浓缩物， 助洗剂物质，稳定剂和任选的无机无机酸，络合剂和/或防腐剂。 组分B含有作为活性成分调节至1至11范围内的pH，通过用无机酸或在水溶液中酸性反应的气体处理碱金属硅酸盐溶液而原位获得的硅酸分散体。 分散体还含有稳定剂，表面活性剂和助洗剂物质。 如果需要，还可以加入常规包含在清洁浓缩物中的另外的试剂。 本发明还涉及通过用无机酸或气体在水溶液中酸性反应的碱金属硅酸盐溶液处理碱金属硅酸盐溶液并向其中加入表面活性剂，稳定剂和助洗剂物质来制备这种清洁剂的方法。
