Effect of Polymer/Cement Ratio on Capability of Long-life Inorganic Based Materials Used for Metal Tanks

For studying the effect of polymer/cement ratio (R) on the performance of inorganic-based long-life anti corrosion materials used for metal tanks, the performance differences such as mechanical properties, anti-corrosion ability and aging resistance were investigated. The internal relationships between microstructure and macroscopic properties were studied by scanning electron microscopy. The results showed that when the R value was in the range of 0.3-0.5, the material exhibited the best overall performance. Appropriately adjusting the R value within this range, long-life inorganic-based corrosion material with different flexibility would be prepared. And the polymer emulsion and cement formed a three-dimensional network structure, which enhanced the composite effect. The three-dimensional structure made the material exhibit high weathering resistance and good strength of inorganic materials as well as good flexibility, strong adhesion and excellent corrosion resistance of organic materials.
