METHOD FOR PRODUCING ENCAPSULATED SODIUM PERCARBONATE PARTICLES

摘要

In a method for producing encapsulated sodium percarbonate particles by spraying a sodium-sulphate-containing aqueous solution onto sodium percarbonate particles in a fluidized bed and simultaneous evaporation of water, for producing the sodium sulphate-containing aqueous solution, use is made of sodium sulphate and sodium percarbonate-containing dust.
