How to control sacrificial anodes to ensure the quality of their products? How to control it? It is mainly to simplify the analysis and control of the chemical composition of the alloy, as well as the joint degree materials between the support and the anode, the quality of the anti-corrosion coating, the quality and size of the support and the anode. Since the free flow test will last for a long time, a short-term constant current test is required during the control process. In addition, there are some technical specifications that describe special test conditions related to actual conditions. However, such test results can only represent the current comparable values and cannot be used as valid data in actual conditions. Objects that require long-term protection of anode materials. Sometimes strict control of certain special alloys is required in production. Such special anode materials usually require test certificates.
The use of sacrificial anode cathodic protection usually does not require great technical costs. After the cathodic protection system is installed, as long as the protection current or potential is occasionally checked, subsequent operations require almost no maintenance. Since the driving voltage is low and does not interfere with nearby structures, the cathodic protection system of the sacrificial anode does not require alternating current. Because the voltage is relatively low, there is no problem. Therefore, the sacrificial anode system can be installed in areas with explosion hazards. When anti-corrosion is carried out in the soil, the anode can be placed together with the protected structure and buried in the same pit without digging the soil. Connect the anode to the local harmful structure to overcome interference.
However, due to the low driving voltage, the application of sacrificial anodes in soil and media with poor conductivity is affected. If the current output needs to be increased during use, it is feasible to increase the external voltage only. Sacrificial anode manufacturers In special cases, the installed sacrificial anode is over-calendered, such as strips or reaction products can increase its supplementary function and should be used.
