缓蚀剂通常是指加在腐蚀环境中能够阻止或减缓金属腐蚀过程的一类化学物质。随着金属腐蚀与防护科学的发展,缓蚀剂的开发、研究、使用愈益受到人们的重视。几种唑类有机缓蚀剂对有色金属的防蚀发挥重要的作用。一、三唑类1.2.4-三唑(1.2.4-Triazole,TA)该类化合物用作缓蚀剂有水溶性,有耐热、耐光、耐药品的良好稳定性和很低的毒性。此外,其中有的具备挥发性,能在密封容器内长时间维持有效的缓蚀浓度。由于含活泼氢的三唑环对金属的结合力较大,活泼氢能与金属铜
Corrosion inhibitors generally refer to a class of chemicals that are added to a corrosive environment to prevent or slow the process of metal corrosion. With the development of metal corrosion and protection science, the development, research and use of corrosion inhibitors have drawn more and more attention. Several azole organic corrosion inhibitors play an important role in the corrosion protection of non-ferrous metals. Triazoles 1.2.4-Triazole (TA) These compounds are water-soluble as corrosion inhibitors and are heat-stable, light-fast and resistant to chemicals with low toxicity . In addition, some of them are volatile and maintain an effective corrosion inhibition concentration in a sealed container for a long time. Triazole ring containing active hydrogen because of the larger binding force of the metal, active hydrogen and copper metal
