[0015] The corrosion rate and scale inhibition rate tests are all carried out using the relevant methods in the "Cooling Water Analysis and Experimental Methods" of Sinopec. The relevant calculation formula is:
[0016]
[0017] :Corrosion vector of test piece (g)
[0018] A: The area of the specimen (cm 2 )
[0019] T: Corrosion test time (hr)
[0020] ρ: Density of specimen material (kg / m 3 )
[0021] The scale inhibition rate is calculated as fol...
