摘要:
采用失重法和电化学极化法研究了氨基硫脲在盐酸清洗剂中对碳钢的缓蚀行为,并初步探讨其吸附性能。结果表明:氨基硫脲属于混合型缓蚀剂,在盐酸介质中缓蚀作用良好,20℃下氨基硫脲为30 mg/L时,其缓蚀效率可达93.3%。氨基硫脲的缓蚀效率受温度的影响较大,其在碳钢表面的吸附符合Langmuir吸附规律。
Abstract:
The corrosion inhibition behavior of thiosemicarbazide for carbon steel in a hydrochloric acid so-lution was studied by weight loss and electrochemistry polarization method, and the absorbance of thiosemicarbazide on carbon steel was preliminary discussed. The results showed that thiose-micarbazide, as a complex inhibitor, gave nice inhibition efficiency on carbon steel in hydrochloric acid medium. The inhibition efficiency of thiosemicarbazide was up to 93.3% when the thiosemi-carbazide reached 30 mg/L at room temperature. The inhibition performance of thiosemicarbazide is affected by temperature, and its absorbance behaviors can be expressed by the equation of Langmuir model.
