Methods of Combining Corrosion Inhibitors with Polymer Films

3 Methods of Combining Corrosion Inhibitors with Polymer Films 

Mixing of Cl with the polymer base is considered to be the most important operation that governs anticorrosion properties of the film material. Modern technologies allow binding of Cl with the polymer by the encapsulation of the inhibitor particles into the polymer binder with free fixing on the film surface. 

The existing methods of Cl introduction into the pol uner films can be subdivided into four groups (Fig. 2.4). 

The first group of methods presupposes joint processing of polymer melts with Cl in either liquid or solid phases. Easily volatile Cl may be transferred into the gaseous phase and foam the polymer during processing [3,4,7,14,23, 24]. 

The second trend is based on diffusive saturation of the polymer films with Cl in the liquid or gaseous phases [3,4,30,52].
