Technology of Packing Materials for Metal Products

Abstract:

Survey objective: development of methods for manufacture of combined packaging materials containing volatile corrosion inhibitors (VCIs) and estimation of their corrosion resistance. The investigation outcome includes prototypes of the combined packaging material containing VCIs, developed optimal paper manufacturing design parameters, estimation of their protective properties compared with those of foreign equivalents. Based on the investigation outcome, the following optimal concentrations of inhibitor work solutions are selected to provide protective properties of the obtained materials: 4 mass. % in water solution for VCI-1 and VCI-2; 10 vol. % in nefras for VCI-3. It was found that inhibitor work solutions might be preferably applied on the base paper with a roller because of a low viscosity of inhibitor work solutions and even the inhibitor application obtainable with this method. The optimum temperature value for drying of the combined packaging material is 80 oС because it virtually does not result in change of inhibitor residuals. Tests according to GOST 9.054-75 prove the corrosion-resistive efficiency of the combined packaging materials obtained. Estimation of corrosion-resistive properties of the studied materials has also established that paper covered with VCI-2 is of a universal character as it features high protective properties related to cold and hot-rolled steels. Corrosion inhibiting properties of test samples of combined materials with VCI-1 and VCI-2 are equal to those of foreign equivalents.
