Abstract
A rapidly dissolving granular hydrated calcium hypochlorite product is comprised of hydrated calcium hypochlorite particles having at least 95 percent of the particles within a size range of from about 300 to about 850 microns. The product has a packed bulk density of less than about 1.05 grams per cubic centimeter. When dispersed on the surface of a body of water, such as a swimming pool, at least 3 feet deep, about 70 weight percent or higher of the particles dissolve within one minute.
Claims4
A rapidly dissolving granular hydrated calcium hypochlorite product consisting essentially of hydrated calcium hypochlorite particles having at least 97 percent of said particles within a size range of no greater than about 850 microns and having a packed bulk density of no greater than about 1.05 grams per cubic centimeter.
A rapidly dissolving calcium hypochlorite product, consisting essentially of granular hydrated calcium hypocholrite particles having at least 97 percent of said particles within a size range of no greater than about 850 microns, having an available chlorine concentration of from about 65 to about 72 percent, and having a dissolving rate of about 70 weight percent or higher in one minute when dispersed on the surface of a body of water at least 3 feet deep.
