oa Prevention of Corrosion in Paper Making Machines

Corrosion problems can become severe in paper-making machines in which the pulp is dried over steam-heated castiron cylinders. Paper with a smooth bright surface will be produced provided that the cylinder remains smooth and bright, but corrosive media in the pulp attack the surface. This article describes the successful application of cathodic polarisation, using platinum-titanium anodes, to a large paper-drying cylinder to give it complete protection from corrosion
