In industrial production and daily life, water treatment is a crucial step in ensuring stable equipment operation and extending its service life. Scale and corrosion inhibitors, as important chemical agents in water treatment, effectively solve the problems of calcium and magnesium ion scaling and metal corrosion in water. Today, we'll delve into the working principles and application scenarios of these agents.
1. Scale Inhibition Function: Through chelation and dispersion, they prevent calcium and magnesium ions in water from forming scale. For example, in boiler water, they can transform calcium carbonate crystals into stable, dispersed particles that are discharged with the water flow.
2. Corrosion Inhibition Function: They form a protective film on the metal surface, isolating dissolved oxygen and corrosive ions in the water, thus reducing the rate of electrochemical corrosion. Common organophosphonate agents can form a passivation film on steel surfaces.
