Spontaneity, universality, and concealment
Universality, concealment, gradualness, and suddenness
Spontaneity, universality, concealment
Corrosion is characterized by (universality), (hidden nature), and (gradual progression)
I had no prior exposure to this; I found it by searching on Baidu. Answer: The factors that affect the working exchange capacity of resin are related not only to the properties of the ion exchange resin itself but also to the following factors: (1) The working exchange capacity is higher during countercurrent regeneration compared to forward flow regeneration. (2) The ion concentration in the feed water, the control parameter for the exchange endpoint, and the ion concentration in the effluent also determine the working exchange capacity. (3) Quality of the regeneration agent, control of regeneration process conditions. (4) Flow rates that are too fast or too slow are not conducive to ion exchange, affecting the exchange capacity of the resin. (5) A high water temperature is favorable for ion exchange; generally, 25–50°C is appropriate. (6) For ions with high selectivity coefficients, the working exchange capacity of the resin must be correspondingly high. (7) The more thoroughly the resin is regenerated, the greater its working exchange capacity. (8) Degree of contamination of the ion exchange resin.
Corrosion has (electrochemical), (electronic), and (diffusion) characteristics.
