Abstract
Verfahren zur Reinigung starrer Oberflächen mit builderhaltigen alkalischen Lösungen. die durch Zusammenführen eines stark alkalischen und eines sauren oder neutralen Wirkstoffkonzentrates, wobei das alkalische Wirkstoffkonzentrat zur Erzielung eines alkalischen Milieus im Überschuß eingesetzt wird, erhalten werden, in dem als saures oder neutrales Wirkstoffkonzentrat eine Dispersion von Kieselsäure verwendet wird. Die bei dem Verfahren verwendeten Mittel können einen weiteren Zusatz an Phosphorsäure, die teilweise durch Schwefelsäure ersetzt ist, enthalten.Process for cleaning rigid surfaces with builder-containing alkaline solutions. which are obtained by combining a strongly alkaline and an acidic or neutral active substance concentrate, the alkaline active substance concentrate being used in excess to achieve an alkaline medium, in which a dispersion of silica is used as the acidic or neutral active substance concentrate. The agents used in the process can contain a further addition of phosphoric acid, which is partly replaced by sulfuric acid.
