Influence of cathode polarization on protective properties of thermoreactive coatings for main pipelines
Ключові слова:
гібрид-епоксидний покрив, захисний потенціал, катодна поляризація, катодне відшарування, поліуретановий покрив.Анотація
Досліджено вплив катодної поляризації за циклічної зміни температур (від кімнатної до 70 оС) на
захисні властивості нових та штучно зістарених термореактивних покривів для магістральних
трубопроводів. Показано, що катодне відшарування покривів залежить від їх властивостей, температури,
наведеного потенціалу. Встановлено, що зниження (за абсолютним значенням) захисного потенціалу з
омічною складовою від -1.45 до -0.75 В сприяє збереженню захисних властивостей покривів: радіус
відшарування нового гібрид-епоксидного зменшується в 3.3, зістареного – в 1.7 разів; нового та зістареного
поліуретанового – більше ніж у 20 разів.
