Natural Corrosion Inhibitors The turpentine and lavender oils isolated from natural plants were used as the corrosives for copper corrosion in acid liquids, which were the early applications of copper in acid liquids.
It was later discovered that some colloidal substances such as gum arabic, protein, gelatin, dextrin and potato starch have a better corrosion inhibition effect on copper in hydrochloric acid solution.
In addition, the method of applying lubricating grease is used to prevent corrosive gas reactions or delay the occurrence of corrosion. A.Y.EleEtre used weightless method and electrochemical technology to study the inhibitory effect of natural honey on copper.
Natural honey has a good corrosion inhibition effect on copper in 0.5mol / L NaCl solution, and the adsorption of honey on the copper surface follows the Langmiur isothermal adsorption rule, but due to the deterioration of honey, the corrosion inhibition effect gradually decreases after a few days.
