Abstract: An in-service formulation for the removal of scale deposits from metallic working surfaces of boilers and for the ongoing prevention of build-up of such deposits on boiler surfaces, with such deposits commonly consisting of insoluble salts of calcium together with oxides of iron. The formulation comprises a blend of selected phosphonates, sodium lignosulfonate, one or more scale-modifying polymers, along with one or more chelants. Sodium gluconate is utilized for its ability to inhibit corrosion of ferrous surfaces. The pH of the working solution is adjusted to a level of between about 10.5 to 12.5. The formulation of the present invention provides a significant capacity for the removal of scale while remaining fully compatible with the water present in the system during and after scale removal, and the materials remain effective with contaminants present in the boiler water following a substantial number of cycles of concentration.

Abstract: An in-service formulation for the removal of scale deposits from metallic working surfaces of cooling towers and for the ongoing prevention of build-up of such deposits on cooling tower surfaces, with such deposits commonly consisting of insoluble salts of calcium together with oxides of iron. The formulation comprises a blend of selected phosphonates, one or more scale-modifying polymers, along with one or more chelants. Sodium gluconate is utilized for its ability to inhibit corrosion of ferrous surfaces as well as its synergistic effect in conjunction with other constituents for the removal of scale components (as demonstrated in U.S. Pat. No. 4,279,768). In those systems having non-ferrous metallic surfaces, such surfaces have been found to be adequately protected by the formulation through the incorporation of a triazole inhibitor.

Abstract: A scale removing formulation designed to remove scale build-up on metallic working surfaces, the scale being conventional and composed of calcium salts and iron oxides from aqueous systems such as boilers, cooling towers, heat exchangers, and the like, while those systems are in service. The present invention utilizes a synergistic blend of a chelant, polymeric conditioners and a gluconate. Principle components of the formulation of the invention include a chelant, polymeric conditioners, a gluconate, a triazole, and sodium sulfite. The gluconate is utilized as an inhibitor for ferrous metal surfaces, with the triazole being utilized as an inhibitor for non-ferrous metal surfaces. The sodium sulfite is employed for removal of dissolved oxygen.

Abstract: A semi-synthetic lubricant for high temperature applications, particularly adapted for use on relatively movable metallic surfaces during the shearing of molten glass, and consisting of an aqueous solution of a formulation comprising a non-drying vegetable oil, such as coconut oil, alkanolamine, the phosphate ester of an ethylene oxide adduct of a linear primary alcohol, an emulsifier, preferably the ethoxylated sorbitol hexaoleate, the fatty nitrogen derivative of distilled coconut oil primary amine, and a wetting agent. The wetting agent is preferably the methyl ester of a 50:50 mixture of methyl palmitate and methyl oleate.
