重型汽车水箱用缓蚀阻垢剂的开发

摘要本课题在模拟重型汽车水箱工作条件的基础上，对现有的缓蚀阻垢剂配方进行了分析及改良。采用重量法并通过改变投加量及pH值研究了高温下缓蚀剂对铁、铜、铝的缓蚀性能。结果表明，硝酸钠、亚硝酸钠、钼酸钠、苯并三氮唑、硅酸钠、癸二酸和四硼酸钠的复配缓蚀阻垢剂具有较好的缓蚀阻垢性能。较佳的复配药剂投加量分别为：硝酸钠 700mg/L、亚硝酸钠 1200 mg/L、钼酸钠 600 mg/L、苯并三氮唑 100 mg/L、硅酸钠 400 mg/L、癸二酸 300 mg/L、四硼酸钠 500 mg/L。59865

Title Development of corrosion inhibitor for heavy car tank

Abstract On the basis of simulating working conditions of heavy car tanks, this paper focuses on the analysis and improvement of the existing corrosion inhibitor formulations. The corrosion inhibition performance on iron, copper and aluminum at high temperature of the developed corrosion inhibitors were studied by gravimetric mrthod with different dosages. The results showed that the composite inhibitor composed of sodium nitrate, sodium nitrite, sodium molybdate, benzotriazole, sodium silicate, sodium tetraborate, and sebacic acid showed rather good performance, and the dosage was: sodium nitrate, 700 mg/L; sodium nitrite, 1200 mg/L; sodium molybdate, 600 mg/L; benzotriazole, 100 mg/L; sodium silicate, 400 mg/L; sebacic acid, 300 mg/L; and sodium tetraborate, 500 mg/L.
