the inhibitor itself depends on the source of corrosion. of course to specify the concentration of each one of the raw materials you need to make different experiments with different concentration of each one of the raw materials each time to reach to the optimum value of each one of them.
to determine the concentration of corrosion inhibitor you should also know the triggering agent, or you want to inhibit corrosion in addition to the type of base material to be protected.
I have met are excellent results nitrite based inhibitors to delay the corrosion of steel in concrete
Phd Yahya Jani, may I know how can I specify the concentration of the raw material? Is the method of adding a little volume to the solution like sodium chloride can be used? The concentration of the raw material can be the ratio of the volume of the raw material to the volume of the sodium chloride?
Phd H. Bolognini, may I know what is mean by the triggering agent? Do sir mean an addition of solution like palm oil is needed as the environment solution that I use is sodium chloride? Can I just add the raw material only to the sodium chloride?
I think you should know the capacity of combination between the inhibitor and the agent or substance you want to inhibit.
for example tricalcium aluminate C3A present in the cement is combined with chloride free to some extent this is a natural cement inhibitory action but depends on the amount of free chloride present in the matrix of the mortar or concrete when the capacity is exceeded combination C3A free chloride attacks corroding reinforcing steel
Sorry, sir! I am unable to understand the capacity of combination explained by sir, I think it is too expert for me.
Do sir mean the inhibited solution, like palm oil is needed when I carry out my experiment on testing the effect of the inhibitor on a material? Palm oil is needed to be added to the solution of sodium chloride with some concentration of inhibitor?
