[Application] It can be used as a corrosion inhibitor for the pickling of boilers and equipment.

(1) The influence of temperature on corrosion inhibition efficiency

In a 10% hydrochloric acid solution, the amount of corrosion inhibitor added is 1.

The polycondensate of aniline and urotropine is an adsorption corrosion inhibitor, and the temperature directly affects its adsorption and desorption ability on the metal surface

(2) The influence of acid concentration on corrosion inhibition efficiency

As the acid concentration increases, the corrosion inhibition efficiency of the corrosion inhibitor increases, but when the acid concentration increases to a certain value (15%), the corrosion inhibition efficiency of the corrosion inhibitor decreases

(3) The influence of the amount of corrosion inhibitor added on the corrosion inhibition efficiency

The corrosion rate of A ₃ steel in 10% HCI solution is closely related to the concentration of corrosion inhibitor

(4) The effect of corrosion inhibition time on corrosion inhibition efficiency

The influence of time on corrosion inhibition efficiency is shown in Table 6-10
