Performance Benefits
Performance demonstration
1.Test conditions: temperature 20, acid concentration 25%, processing time 1h, iron sheet quality 25g, the ordinate is the weightless mass g
20 Under the same conditions, compared with the sustained-release effect in eight conventional acids, H628 in nitric acid was significantly worse than that of the comparison sample*Xing826;In phosphoric acid, H628 was slightly worse than the comparison sample, and among the other six acids, H628 was better than the comparison sample.
2.Test conditions: temperature 60, acid concentration 25%, processing time 1h, iron sheet quality 25g, the ordinate is the weightless mass g, and nitric acid is 10 times smaller.
60 Under the same conditions, among the eight conventional acids, H628 was significantly better than the comparison sample*Xing826, and the two corrosion inhibitors basically had no slow-release effect on nitric acid (the actual corrosion data of nitric acid shown in the figure required *10 times).
Fields of application
How to use:
The specific usage method and dosage are flexibly adjusted according to the actual situation, and the general recommendations are as follows:
Add the metered water and the metered product to the liquid mixing tank and stir well.
The concentration of the preparation corrosion inhibitor is generally 02-0.3% (weight). First, stir the metered corrosion inhibitor 1:10-20 with water (the water is warm water at 50-60 degrees) until completely dissolved, and then add the remaining metered water and stir wellThe measured acid is slowly added to the above-mentioned prepared liquid with pickling solution, and the acid is completely dissolved by constant stirring, and the solution can be used after being mixed evenly. Corrosion inhibitors are suitable for acid solutions of various concentrations. The temperature should not exceed 60 °C, otherwise the corrosion inhibitor will easily fail.
H628 currently has limited sustained-release effect on nitric acid and is not recommended for use in nitric acid or mixed acids containing nitric acid.
