    摘要： Articles of aluminum are pickled by placing them as anodes into a sulfuric acid bath in the absence of chromic acid or bichromate and connecting them by a short-circuit connection to a carbon cathode placed in the same bath. The process also excludes the application of an anodic control voltage.

    摘要翻译： 在不存在铬酸或重铬酸盐的情况下，将它们作为阳极放置在硫酸浴中并将它们通过短路连接与放置在同一浴中的碳阴极连接起来将铝制品浸泡。 该方法也不包括施加阳极控制电压。

    摘要： Articles of aluminum are pickled by immersing them into a sulfuric acid bath containing no chromic acid or bichromate but having carbon particles suspended therein. The carbon particles will form tiny electric cells with the aluminum articles at their places of contact and will initiate electrochemical dissolution phenomena there at the point of contact.

    摘要： A method and formulations for cleaning painted aluminum siding and other metal, organic resin and the like surfaces comprising applying to the surface a layer containing a water-insoluble finely divided absorbent material and an oxide remover solution such as an aqueous acidic solution containing a phosphate radical and after the first layer has dried applying thereover a second layer which contains water-insoluble finely divided solid absorbent material in a liquid mixture including a water-soluble organic solvent and a compound selected from the group consisting of sodium nitrite, soluble silicates, and a water-insoluble organic solvent and after the first layer has been absorbed through the first layer removing the layers as by washing with water. The invention has special utility for cleaning and preparing architectural aluminum siding for refinishing with paint or other protective coatings.

    摘要： A composition for cleaning aluminum and aluminum alloy surfaces which comprises from about 1 to 30 percent by weight phosphoric acid and from about 0.15 to 15 percent by weight nitric acid, the weight ratio of nitric acid to phosphoric acid being about 0.020.6:1. This solution further contains from about 0.05 to 20 percent by weight of a nonionic surface active agent, which is stable in the nitric acid containing solution. This cleaning composition is particularly adapted for use in the spray cleaning of aluminum alloy surfaces which contain 2 percent or more of alloy elements, such as magnesium.
