It is a chemical agent used in the metal pickling process. Pickling corrosion inhibitor is a kind of corrosion inhibitor used in the process of hydrochloric acid pickling, and the main component is imidazoline. Its main function is to inhibit the corrosion of the metal matrix by hydrochloric acid when using hydrochloric acid for metal cleaning, so as to protect the metal from excessive erosion. This corrosion inhibitor is added when hydrochloric acid cleans metal, which can inhibit the corrosion of steel by hydrochloric acid, reduce the corrosion rate of metal, and has a good corrosion inhibition effect. This corrosion inhibitor is suitable for pickling processes in all types of high, medium and low pressure boilers, large equipment, and pipelines. In addition, it has an excellent ability to inhibit hydrogen absorption by steel during the pickling process, thereby avoiding "hydrogen embrittlement" in steel. At the same time, it can also inhibit the corrosion of Fe on the metal during the pickling process, so that the metal does not produce porosity.
The main components of special pickling corrosion inhibitors for hydrochloric acid are imidazoline compounds, as well as other corrosion inhibitors and additives. It can form a strong and dense protective film on the metal surface to prevent the erosion of hydrochloric acid.
The special pickling corrosion inhibitor for hydrochloric acid is suitable for the pickling of various types of high, medium and low pressure boilers, as well as the pickling of large equipment and pipelines. It is suitable for hydrochloric acid of various concentrations and temperatures, simple operation, small dosage, high efficiency, low cost, non-toxic and odorless, and non-polluting to the environment. In addition, it also has excellent ability to inhibit hydrogen absorption in steel during pickling, avoid "hydrogen embrittlement" in steel, and inhibit the corrosion of FE on metal during pickling, so that the metal does not produce porosity.
Shandong Jiequan Environmental Protection Technology Co., Ltd. reminds you that when using the special pickling corrosion inhibitor for hydrochloric acid, it needs to be added to the cleaning solution in a certain proportion, and the specific addition amount and use method can be adjusted according to the actual situation. At the same time, in order to ensure the cleaning effect and safety, it is recommended to operate under the guidance of professionals.
In a word, the special pickling corrosion inhibitor for hydrochloric acid is an important chemical, which can effectively protect the metal surface from the damage of hydrochloric acid corrosion and improve the service life and safety of the metal.
