Effect of Waterproof Emulsion on Properties of Calcined Gypsum from Flue Gas Desulfurization
Effect of the vinyl acetate - ethylene copolymer emulsion (VAE emulsion), styrene-acrylic emulsion and paraffin emulsion were studied on waterproof properties and mechanical properties of calcined gypsum from flue gas desulfurization (FGD). The results showed that waterproof properties of samples which mixed paraffin emulsion were most excellent, but mixing paraffin emulsion caused the negative effect to the mechanics properties of samples. Adding appropriate content of VAE emulsion was advantageous to waterproof properties and mechanical properties of samples. Scanning electron microscope was used to observe the microstructure of samples, and the mechanism of waterproof emulsion was discussed.
