CORROSION-INHIBITING CLEANING SYSTEMS FOR ALUMINUM SURFACES, PARTICULARLY ALUMINUM AIRCRAFT SURFACES |
摘要 |
An alkaline blast cleaning system for aluminum surfaces which avoids discoloring or tarnishing of the aluminum surfaces, is comprised of an alkali metal bicarbonate having a particle size of from about 50 to about 1000 and an aqueous solution of sodium silicate, the sodium silicate having an SiO2:Na2 O ratio of from about 2.44 to about 3.22:1 and being present in the aqueous solution in a corrosion inhibiting concentration of from about 100 to about 1000 ppm., the pH of the solution ranging from about 8.1 to about 8.3. |
