采购铝合金牺牲阳极就在焦作立博Buy aluminum alloy sacrifice anode on Jiaozuolibo
产品名称：铝合金牺牲阳极
常用的铝合金阳极有Al－Zn－In系和Al－Zn－Hg系阳极，适用于海水中的船舶、码头港口与海洋设施、海水冷却水系统和储罐沉积水部位等构筑物的阴极保护。lb17184466
执行标准：
GB/T 4948－2002《铝－锌－铟系合金牺牲阳极》。
主要性能：
的电化学性能、单位重量的阳极材料发电量大，约为锌阳极的3倍，镁阳极的2倍。在海水及含氯离子的其它介质中，性能良好，发出电流的自调节能力强。
阴极措施是将铺设在地下的某些流程进行改造，使遭到了一定的破损涂层得到保护，这是附加的保护措施之一。这种保护措施对于破损处的保护效果非常好的。目前，有许多的建设工程都会有在流程改造中增加电流阴极保护的措施，甚至还有一些工程会通过牺牲阳极来保护阴极。随着近几年保护措施渐渐趋近成熟，对于是由企业工艺流程改造的保护措施也开始有了一个准确的行业标准。这相对于其他的保护措施来说，这项保护措施的施工难度是小的，并且没有许多的安装工作量，因而也不会对流程改造周边的一些金属的建筑物产生不良的影响。总的来说使用价值是很高的。
The cathodic protection is an effective and economical corrosion control method in oil production. For buried pipelines, the coating was already in place before laying, but the coating will leave leakage points, and exposed areas will also be generated during construction, and it will account for about 5 %. The cathodic protection is required, otherwise it will cause centralized corrosion and perforation. The use of internal coating or lining is one of the effective ways to prevent corrosion in the pipeline, but the surface treatment is difficult, and uneven and uneven needle holes and leakage points often appear. At the same time, the coating and the metal elastic modulus are inconsistent, which will lead to damage to the coating, resulting in cracks and reduced life. The central point erosion caused by the leakage point is more serious than the corrosion of the bare tube surface.
The use of cathodic protection and internal coating protection is a relatively complete anti-corrosion method. The sacrifice anode makes the steel a cathode. Its surface is alkaline and inhibits corrosion. At the same time, the inner surface of the steel pipe can form a dense scale layer and also play a protective role. The test results of corrosion pendant show that the protection of the sacrificial anode can reach about 98 %.lb17184466
