Environmentally Friendly, Energy-Saving Technology for Encapsulation of Granules in Thin Waterproof Polymer Shells

摘要

For enhancing environmental safety, aqueous emulsions of polymer solutions are suggested as encapsulants for the combined process of prilling of melt drops in an encapsulant solution followed by separation of the encapsulant solvent from the granules by utilizing the residual heat of the phase transition.
