９５—０２８ 羧酸酰肼作钢在酸性介质中的缓蚀剂碳酸酰肼（ＣＡＨ）可抑止盐酸溶液中０８ｋｐ钢的氢吸附。对钢的强度没有负影响。ＣＡＨ在硫酸中的缓蚀效率远不如在盐酸中的缓蚀效率。在盐酸中加入碳酸酰肼后，钢的自然腐蚀电位提高１０～２０ｍＶ，这是因为混合型的缓...
95-028 Carboxylic acid hydrazide as corrosion inhibitor for steel in acidic media Carbonyl hydrazide (CAH) inhibits the hydrogen adsorption of 08kp steel in hydrochloric acid solution. No negative effect on the strength of the steel. The corrosion inhibition efficiency of CAH in sulfuric acid is far less than the corrosion inhibition efficiency in hydrochloric acid. After the addition of carbonic acid hydrazide in hydrochloric acid, the natural corrosion potential of steel increased by 10 ~ 20mV, because of the mixed type of slow ...
