<p>Use of mixtures of water-soluble organic compounds as cold forming auxiliary materials comprising the content of alkali and/or amine salts of alkanoyl amino carboxylic acid (I) in the mixture with triethanol amine, acid phosphoric acid ester of a polyether and a non ionic surfactant like ethylene glycols and block polymers of propylene oxide and ethylene oxide, in the metal industry, is claimed. Use of mixtures of water-soluble organic compounds as cold form auxiliary materials comprising the content of alkali and/or amine salts of alkanoyl amino carboxylic acid of formula (R 1>-N(-(CH 2) n-COOH)-(CH 2) m-N(-R 2>)-(CH 2) n-COOH) (I) in the mixture with triethanol amine, acid phosphoric acid ester of a polyether and a non ionic surfactant like ethylene glycols and block polymers of propylene oxide and ethylene oxide, in the metal industry, is claimed. R 1>6-20C alkanoyl residue; R 2>R 1>or -(CH 2) n-COOH; n : 1-3; and m : 2-6. An independent claim is included for use of water-based drilling fluids, cutting material and grinding material in the stone machining process in which the cold forming auxiliary materials are added as a lubricator in an amount of 3-25%.</p> |
