用失重法研究了在磷酸介质中 ,含氨有机物硫脲 (SN)、柠檬酸三铵 (CNO)和十六烷基三甲基溴化铵 (CHNB)对锌的缓蚀作用。 3种有机物的缓蚀率排序为 :CHNB >>SN >CNO ,用吸附理论解释了实验结果。
The corrosion inhibition effect of ammonia-containing organic thiourea (SN), triammonium citrate (CNO) and cetyltrimethylammonium bromide (CHNB) on zinc in phosphoric acid medium was studied by weight loss method. The order of the corrosion inhibition rates of the three organic compounds is CHNB >> SN> CNO, and the experimental results are explained by adsorption theory.
