1. The action principle of ternary carboxylic acid rust inhibitor and triethanolamine

Ternary carboxylic acid rust inhibitor is an important component of anti-rust solution, which can protect the metal surface from oxidation corrosion. Triethanolamine is a weakly alkaline solvent, which can promote the reaction and penetration of rust prevention agents. The reaction of ternary carboxylic acid rust inhibitor with triethanolamine can make the rust inhibitor penetrate into the metal surface better and play a better role in rust prevention.

2, ternary carboxylic acid rust inhibitor and triethanolamine reaction ratio is appropriate?

The reaction ratio between ternary carboxylic acid rust inhibitor and triethanolamine needs to be determined according to the specific situation. In general, the reaction ratio of ternary carboxylic acid rust inhibitor and triethanolamine is between 1:1 and 1:3. If the amount of triethanolamine is too much, it will lead to the dilution of anti-rust agent and the decline of anti-rust performance. If the amount of ternary carboxylic acid rust inhibitor is too much, it will waste the cost of rust inhibitor, but at the same time, it will not affect the rust prevention effect.

3. How to prepare anti-rust solution

1) Prepare the required materials: ternary carboxylic acid rust inhibitor, triethanolamine, deionized water.

2) Mix ternary carboxylic acid rust inhibitor and triethanolamine evenly according to the reaction ratio.

3) Add the mixed solution to deionized water and stir well to prepare the anti-rust solution.

4) Adjust the pH value and concentration of the anti-rust solution to the value most suitable for preventing rust.

4, precautions for the use of anti-rust liquid

1) Once the anti-rust solution is prepared, it should be applied on the metal surface as soon as possible.

2) During the application process, it should be ensured that the metal surface is clean and dry to ensure the penetration and adhesion of the anti-rust agent.

3) After the anti-rust liquid is applied, it should be checked regularly and recoated to ensure that the metal surface is rust-proof for a long time.

【 Conclusion 】

The reaction ratio between ternary carboxylic acid and triethanolamine has certain influence on the effect of antirust agent. According to the actual situation, the reaction ratio of ternary carboxylic acid rust inhibitor and triethanolamine can be adjusted between 1:1 and 1:3. In the process of preparing the anti-rust liquid, pay attention to adjusting the pH value and concentration of the anti-rust liquid to adjust the value most suitable for preventing rust, and ensure that the metal surface is clean and dry when applying the anti-rust liquid. Regular inspection and reapplication of rust inhibitor can ensure long-term rust prevention effect.
