| 中文摘要: |
| 采用失重法研究了在不同温度下,不同浓度的苯扎溴铵在3%的氢氟酸溶液中对锌的缓蚀作用,实验结果表明:在3%的氢氟酸溶液中,苯扎溴铵对锌的腐蚀具有良好的抑制作用。苯扎溴铵浓度低时,随浓度增大,缓蚀作用加强;当其浓度达到一定值后,缓蚀作用基本保持不变。根据结构理论分析,苯扎溴铵在锌表面的吸附是产生缓蚀作用的重要原因,吸附规律服从Langmuir等温式。采用Sekine方法处理实验数据,获得了一系列相关热力学参数。 |
| 英文摘要: |
| The corrosion inhibition of benzalkonium on zinc in 3%hydrofiuoric acid solution was investigated with different temperatures and different concentration of benzalkonium by weight-loss method. The results show that the benzalkonium bromide on the corrosion of zinc has a good inhibitory effect in 3% hydrofluoric acid solution. The corrosion inhibition of benzalkonium bromide increases with the increaesing of concentrations of benzalkonium bromide.When its concentration reaches a certain concentration, corrosion inhibition remaines basically unchanged. According to the structural theory analysis the adsorption of benzalkonium on the surface of zinc is the important reason resulted from corrosion inhibition, benzalkonium bromide in the surface of zinc to obey the law of Langmuir adsorption isotherm. The experimental data are treated by the Sekine metheod and the correlative thermodynamics parameters are obtained. |
