Problems solved by technology

However, corrosion inhibitor technology has obvious limitations. In the liquid medium where corrosion inhibitors are most widely used, corrosion inhibitors must have a certain solubility and must reach a certain concentration.
Traditional corrosion inhibitors have polluted the environment due to their high toxicity; at the same time, due to the small amount of corrosion inhibitors used, small changes in the outside world will have a greater impact on the system, which also brings new challenges to the study of corrosion inhibition mechanisms. These factors have limited the further development of corrosion inhibitors

Description

technical field [0001] The invention relates to the field of anticorrosion materials, in particular to a kind of anticorrosion material for towers. Background technique [0002] The tower is a support used to support the transmission line in the overhead transmission line. The tower is mostly made of composite materials or reinforced concrete. Among them, the tower made of reinforced concrete is relatively clumsy and is rarely used now; the tower made of composite materials can be Effectively reduce line corridors and reduce tower weight. However, the corrosion of composite materials in various environments has caused huge losses, so the protection of metals is of great significance. Among various metal corrosion protection technologies, corrosion inhibitor technology has become one of the most effective and commonly used methods due to its simple process and strong applicability. However, the corrosion inhibitor technology has obvious limitations. In the liquid phase medi...
