Anti-corrosion Properties of Life-time Anti-corrosion of Metal Oil Tanks Modified by Water Reducer

Three types of water reducers (polycarboxylate,aminosulfonic acid and naphthalene series) were added in different ratios to life-time anti-corrosion material of metal oil tanks.The results showed that polycarboxylate series had the best decreasing water effect with additional amount about 1.0%.Then the experiments of normal temperature conservation,ultraviolet ray aging and saline soak were perpormed ,it was found that the anti-corrosion material showed marvelous mechanical properties with additional amount about 1.0% of polycarboxylate series.The metal plate surface without adding polycarboxylate series showed different levels of corrosion in the experiments of ultraviolet ray aging and saline soak,but the metal plate surface with adding about 1.0% of polycarboxylate series nearly kept completed.
