  • Patent number: 6124252
    Abstract: A multipurpose scale removal compound having a nonyl phenol ethoxylate with 10 moles of ethylene oxide at 0.85% of a total weight of the compound, hydrofluoric acid at 0.85% of the total weight of the compound, and softened water at 98.3% of the total weight of the compound. This multipurpose scale removal compound is formed by filling a reactor with 160 liters of softened water, adding 20 kilograms of hydrofluoric acid to the water in the first reactor, agitating the hydrofluoric acid and water in the first reactor, adding 20 kilograms of nonyl phenol ethoxylate with 10 moles of ethylene oxide to the first reactor, agitating the nonyl phenol ethoxylate, the ethylene oxide and the agitated hydrofluoric acid and water in the first reactor so as to obtain a uniform solution, adding 182.9 liters of softened water and 17.1 kilograms of the uniform solution to a second reactor, and agitating the softened water and uniform solution in the second reactor so as to obtain a uniform mixture.

  • Patent number: 5972817
    Abstract: A foamed glass article for preparing surfaces, the use therefor, and a method of making same are provided. The foamed glass article is in the form of a block, disk or similar product, and is used for preparing surfaces such as by sanding, rubbing and scraping the same to clean, abrade, polish, smooth, or the like such a surface. The foamed glass article is formed from a starting mixture that comprised glass, 0.10-20% by weight of at least one non-carbon/sulfate based foaming agent, and optionally an additional abrasive material. A mixture of powdered glass and non-carbon/sulfate based foaming agent can be placed in a mold and heated so that the mixture sinters and subsequently foams. Thereafter, the foamed mixture is annealed.
