W artykule przedstawiono wyniki badań wpływu starzenia elektrochemicznego na zmianę właściwości rur wykonanych z polietylenu. Próbki do badań wycięto z rur wykonanych metodą wytłaczania, a następnie poddano procesowi starzenia elektrochemicznego. Proces przyspieszonego starzenia wykonano w roztworze wodnym NaCl, w którym umieszczono próbki przeznaczone do badań. Badania wykonano na próbkach zarówno...
