圆盘铝阳极
铝合金牺牲阳极适用于海水介质中的船舶、机械设备、海洋工程和海港设施以及海泥中管道、电缆等设施金属防腐蚀的阴极保护。
Aluminum alloy sacrificial anode is suitable for cathodic protection of metal corrosion of ships, machinery and equipment, ocean engineering and seaport facilities as well as pipelines and cables in sea mud.
铝牺牲阳极的使用环境 :
Aluminum sacrificial anodes for use in the environment:
处在海水环境中的大部分金属设备或者原油储罐内部底板的阴极保护是不能用在氯离子含量低的土壤环境中。铝牺牲阳极的电极电位为-1.05伏特 ，当周围温度高于49摄氏度时铝牺牲阳极的电容量随着温度的增长而递减，可以参考公式:Z=2500-27（T-20），T阳极工作温度，单位℃。在咸水环境中，铝牺牲阳极的电流容量可能会降低一半。铝牺牲阳极可以直接与需要保护的设备结构固定在一起而不需要其他物质作为填料。
Cathodic protection for most metal equipment in a seawater environment or the internal floor of a crude oil storage tank is not suitable for soil with low chloride content. The electrode potential of aluminum sacrificial anode is -1.05 volts. When the ambient temperature is higher than 49 degrees Celsius, the electric capacity of aluminum sacrificial anode decreases with the increase of temperature. We can refer to the formula Z=2500-27 (T-20), T anode operating temperature, unit ℃. In a saltwater environment, the current capacity of the aluminum sacrificial anode may be reduced by half. Aluminum sacrificial anodes can be fixed directly to the structure of the equipment to be protected without the need for other materials as fillers.
