Classification of Corrosion and Scale Inhibitors

2018-08-28 Hits:4
Corrosion and scale inhibitors are widely used, and there are many kinds and classification methods. People often classify corrosion inhibitors from different angles. The common classification methods are as follows:
1. According to the classification of chemical composition, inorganic inhibitors and organic inhibitors can be classified according to whether the substances constituting the inhibitors are inorganic compounds or organic compounds.
2. According to the classification of the inhibited electrode process, according to whether the inhibition of corrosion and scale inhibitors is anodic or cathodic or both, the inhibitors can be divided into anodic, cathodic or mixed inhibitors. Generally speaking, the anodic corrosion inhibitor makes the corrosion potential Ec of the metal move in the positive direction, the cathodic corrosion inhibitor makes the corrosion potential Ec of the metal move in the negative direction, while the mixed corrosion inhibitor has less influence on the corrosion potential Ec, so the corrosion potential moves very little or not.
3. According to the types of protective films formed and the types of protective films formed by corrosion inhibitors in the process of protecting metals, corrosion and scale inhibitors can be divided into passive film inhibitors, precipitation film inhibitors and adsorption film inhibitors. Among them, precipitation film corrosion inhibitors can be divided into two types: ion type in water and metal ion type.
At present, most of the corrosion and scale inhibitors are added with organic phosphorus and other reagents, so they may emit odor when used, but don't worry, just do a good job of safety protection, there will be no danger. And corrosion and scale inhibitors have the function of softening water quality, can prevent boiler corrosion, transportation process according to chemicals can be, belong to non-dangerous goods, but pay attention to sunscreen and anti-shower, storage in a dry environment, pay attention to waterproof and moisture-proof.
