WORKING ENVIRONMENT FOR ELECTRO-EROSION PROCESSING Russian patent published in 1995 - IPC

FIELD: electro-erosion processing. SUBSTANCE: additional products of double condensation from higher fatty acids or their bottoms with polyamines, monoalkylphenols and ionol as antioxidant comprising (by weight) 0.5 - 1.5 per cent of products of double condensation from higher fatty acids or their bottoms with polyamines; 1.5 - 4.5 per cent of monoalkylphenols; 0.05 - 0.5 per cent of ionol antioxidant enter working environment for electro-erosion processing on the base of kerosene oil fraction of less than 3 mm²/s viscosity at 20 C, 3 - 5.5 per cent of aromatic, 15 - 20 per cent of paraffin, and the balance being naphthenic hydrocarbons. In so doing, content of products from double condensation of their mixture with alkylphenols is 20 - 25 per cent. EFFECT: highly effective solution. 3 cl, 3 dwg, 2 tbl
