Abstract

Verfahren zur Reinigung starrer Oberflächen mit builderhaltigen alkalischen Lösungen. die durch Zusammenführen eines stark alkalischen und eines sauren Wirkstoffkonzentrates, wobei das alkalische Wirkstoffkonzentrat zur Erzielung eines alkalischen Milieus im Überschuß eingesetzt wird, erhalten werden, in dem als saures Wirkstoffkonzentrat eine Dispersion aus Borsäure beziehungsweise Alkaliborat in Phospharsäure im Gewichtsverhältnis 1 : 4 bis 20 verwendet wird. Die Phosphorsäure kann teilweise durch Schwefelsäure ersetzt werden. Die bei dem Verfahren zur Anwendung gelangenden Mittel enthalten also weitere Zusätze Phosphonsäuren und Phosphonocarbonsäuren sowie Tenside.Process for cleaning rigid surfaces with builder-containing alkaline solutions. which are obtained by combining a strongly alkaline and an acidic active substance concentrate, the alkaline active substance concentrate being used in excess to achieve an alkaline environment, in which a dispersion of boric acid or alkali borate in phosphorous acid in a weight ratio of 1: 4 to 20 is used as the acidic active substance concentrate . The phosphoric acid can be partially replaced by sulfuric acid. The agents used in the process thus contain further additives phosphonic acids and phosphonocarboxylic acids as well as surfactants.
