概要

Inorganic or organic acid mixed with hydrogen peroxide solution is found to have higher solubility to metal as well as its inorganic compounds such as scale than conventional acid solution.The author also finds that the hydrogen peroxide solution has an ability to dissolve preferentially metal and scale, when it is used under suitable condition. So it can also be applied to the pickling of metals.The dissolving of various kinds of scale which has heretofore been considered difficult to descale beconmes easy almost without dissolving the metal.Moreover, the metal surface treated by the acid solution contauing hydrogen peroxide is so perfebtly smooth that it can be polished, if necessary, as fine as mirror.With the addition of hydrogen perxide solution the pickling process is much improved to bring about many advantages in metal finishing.
