中文摘要:
      通过静态失重法、动电位极化曲线法及?煜晕⑿蚊?研究了脂肪醇聚氧乙烯醚(平平加O-20)及其复配缓蚀剂在100 mg/ L 二氧化氯介质中对Q235 钢的缓蚀效应。结果表明:平平加O-20 对Q235 钢有一定的缓蚀效果,但单独使用时的用量较大;平平加O-20 与硝酸钠、钼酸钠、苯甲酸钠均有缓蚀协同效果,与苯甲酸钠复配的缓蚀协同效应最明显;当苯甲酸钠和平平加O-20 复配的质量浓度比为6 :4,总用量为300 mg/ L 时,最大缓蚀效率可达92. 55%。
英文摘要:
      The static weight loss method, potentiodynamic polarization and observing microscopic appearance were used to study the synergistic effect of fatty alcohol ethoxylates (peregal O-20) and complexd inhibitors on corrosion inhibition of Q235 steel in the chlorine dioxide media of 100 mg/ L. The results show that peregal O-20 has a corrosion inhibiting effect for Q235 steel,but the amount of corrosion inhibitor is large when used alone; Composite peregal O-20 with sodium nitrate or sodium molybdate or sodium benzoate can produce synergistic inhibition effect on Q235 steel,when composite with sodium benzoate can produce the most obvious synergistic inhibition effect; When the concentration ratio of sodium benzoate and peregal O-20 is 6 : 4 and the total dosage of 300 mg/ L,the maximum inhibition efficiency can achieve 92. 55% .
