摘要： The electrolytic removal of oxides of iron, such as rust and/or scale, from the surfaces of ferrous metals is materially accelerated by incorporating a minor amount of elemental sulfur into the alkaline cyanide-free aqueous electrolyte also containing a complexing agent capable of complexing iron ions into soluble form, and an alkaline material, and having a pH of above 10. Concentrate compositions adapted to be mixed together with water to form the electrolyte are also embodied within the invention.

摘要： A method and composition for reducing the amount of and softening silicate scale formation in automobile and diesel coolant systems where a silicate containing anti-corrosion formula is used which comprises adding to said formula an effective amount of a polymeric dispersant which is a water-soluble carboxylic acid polymer selected from a vinyl addition polymer and a carboxymethyl cellulose. The addition of polymeric dispersants to silicate containing corrosion inhibition formula such as the boron-nitrite type ameliorates or changes the character of the crystalline precipitate to a softer amorphous type and enables the utilization of anti-corrosion formulas at dosages of from about 2,000 up to 20,000 ppm without platingout side effects. Specially preferred dispersants are maleic anhydride copolymers and carboxymethyl cellulose. The advantages of the present invention may be realized in mixed precipitates containing silicate and also anions such as carbonate, phosphate, sulfate, etc., in the presence of alkaline earth cations.
