淡水铝合金牺牲阳极厂家价格
淡水铝合金牺牲阳极厂家价格The development of sacrificial anode cathode protection law has been developed for nearly 200 years. With the development of the application field, the research and development of sacrificial anode suitable for various special environmental requirements has been carried out continuously. At present, research has been conducted on the sacrificial anode for protecting high-strength steel and the sacrificial anode for protecting carbon steel in oil-contaminated seawater at home and abroad, but there is little research on the sacrificial anode for protecting high-strength steel in oil-enriched areas such as ship ballast tanks and deck tanks. Therefore, the development of sacrifice anode suitable for this environment has a certain significance. In this paper, we refer to the research results obtained in the relevant fields, adopt the Al-Zn-In-Bi-Si-Ce six-element anode system, 淡水铝合金牺牲阳极厂家价格 and combine the electrochemical research methods such as polarization curve and AC impedance through constant current sacrifice electrochemistry test. With SEM, macroscopic metallographic observation and EDS analysis, the mechanism of action of alloy elements was studied. For 16 sets of anode formulas with orthogonal design, the current efficiency is taken as the index, and the range analysis is optimized. Four kinds of heat treatment processes were used to analyze the effect of heat treatment on anode properties from electrochemical properties and structure of alloy.
淡水铝合金牺牲阳极厂家价格由于铝的自饨化性能，所以钝铝不能作为牺牲阳极材料。目前已开发了Al-Zn-Hg系、Al-Zn-In系等几个系列，其典型成分见表10-65。由于汞对环境的污染及冶炼困难，目前各国都限制含汞的铝阳有生产。而AI-Zn-In系是目前各国公认的有前途的铝阳极系列。为改善阳极的电化学性能，在三元素合金基础上又添加了第四、第五元素。世界行广的GalValumⅢ型铝阳极为Al-Zn-In-Si系列lb17184466
焦作市立博轻合金有限公司生产防腐材料生产厂家，以的服务，过硬的产品技术在防腐行业里面赢得了新老客户的信赖。立博是科研、生产、贸易于一体，可为客户提供阴极保护全系列设备材料、阴极保护方案设计及阴极保护工程施工等服务。
阴极保护技术是电化学保护技术的一种，其原理是向被腐蚀金属结构物表面施加一个外加电流，被保护结构物成为阴极，从而使得金属腐蚀发生的电子迁移得到抑制，避免或减弱腐蚀的发生。
