説明
In case a hard steel wire (0.6%C, 1mm. dia.) was pickckled in 10% HCl or 10% H2SO4 solution, the effect by the addition of several organic inhibitors, i.e., thiourea, gelatine, glue, aniline, chiloramine-T and commercial inhibitors, in pickling acid were studied on the inhibition efficiency and pickling brittleness.<br>The results were summarized as followed:<br>(1) Generally, an increase of the concentration of the addition agent accompanied an increase of the inhibition efficiency to diminish the attack of pickling acid, until the max. efficiency was attained by a certain concentration which was assumed to correspond to the saturated adsorption of inhibitor on metal, and over that the efficiency was constant except a decrease was shown by thiourea on the contrary.<br>(2) Increasing temperature of the pickling bath increased the efficiency until 50C, but over 60C it rather decreased.<br>(3) The inhibition efficiency of any agent for the hard steel came out respectively 5-10% lower than for softsteel.<br>(4) The effect on the pickling brittleness did not always correspond to the inhibitive effect, and especially thiourea showed quite an inverse relation.<br>After all, the above mentioned agents were better suitable as inhibitor for the hard steel wire in the order: glue gelatine commercial inhibitors.
