在同样条件下比较了铝-锌-铟-硅、铝-锌-铟-镉、铝-锌-铟-锡和三元锌四种阳极的化学特性,以确定铝-锌-铟-硅阳极性能的优劣。试验介质用大连老虎滩的海水和泥沙,配制成10％、40％,70％和100％的海水、淡海水和海泥。主要测定了阳极的自放电时间—电位曲线、极化特性曲线,静态充电曲线和电流效率。试验共进行240小时,自放电时间电位曲线的阳极电流密度为0.5mA/cm~2,电流效率的阳极电流密度为1mA/cm~2,静态充电通以电流密度为2.6mA/cm~3的恒定电流,极化特性曲线变化电流密度从0.5mA/cm~2至0,再增至1mA/cm~2,最后再至0.5mA/cm~2时,观察电位随电流密度的变化规律。
The chemical properties of the four kinds of anodes, Al-Zn-In-Si, Al-Zn-In-Cd, Al-Zn-In-Sn and ternary Zn were compared under the same conditions to determine the Al-Zn-In-Si anode The pros and cons of performance. The test medium is made up of 10%, 40%, 70% and 100% sea water, light seawater and sea mud with seawater and sediment from Dalian Tiger Beach. Mainly measured the anode self-discharge time - potential curve, polarization curve, static charge curve and current efficiency. The test was carried out for a total of 240 hours with an anode current density of 0.5 mA / cm2 at the self-discharge time potential curve, an anode current density of 1 mA / cm2 at a current efficiency, and a static charge at a current density of 2.6 mA / cm3 The change of current density from 0.5mA / cm ~ 2 to 0 to 1mA / cm ~ 2 and finally to 0.5mA / cm ~ 2 also observed the change of current with the current density.
