STUDY OF BARRIER PROPERTIES OF COMBINED PACKING MATERIALS FOR STEEL PRODUCTS

In this research work the barrier properties of combined paper packing materials of different foreign firms for protection of cold-rolled steel in the conditions of atmospheric corrosion are investigated. Coefficients of vapor permeability, diffusion and sorption are calculated. Corrosion tests of hermetic packed samples of cold-rolled steel are carried out by the periodic moisture condensation. It was found out: packing paper of Fislage brand shows high anticorrosive properties that is caused by low diffusion coefficient of water vapors through the packing material.
