Abstract
Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.
Claims5
A method of making an encapsulated reactant having a desired shape or size comprising the steps of:
- providing solid reactant particles;
- providing a water insoluble encapsulating material;
- dispersing the solid reactant particles in the water insoluble encapsulating material and forming a mass of encapsulated reactant having the solid reactant particles dispersed throughout the water insoluble encapsulating material;
- and
- forming a desired shape or size of the encapsulated reactant by extruding, granulating, shredding, grinding, or pressing the mass of encapsulated reactant into the desired shape or size;
- and
- wherein the solid reactant particles are selected from the group consisting of peroxides, permanganates, persulfates, hypochlorite, zero valent iron, halogenated reactants, sodium bisulfate, metabisulfide, and polysulfides.
