Abstract:
The invention relates to an agent for producing a water-in-oil emulsion, which is characterised in that it contains at least one non-ionic surfactant, at least one substance which forms a membrane, at least one organic or inorganic metal salt of calcium, magnesium, iron, manganese or cerium. The invention also relates to a water-in-oil emulsion which contains said type of agent, a method for hydrophilising organic oil and to the use of said agent for producing a water-in-oil emulsion. The invention is used, preferably, for hydrophilising organically based cutting cooling agents, organically based traction and moulding oils, diesel fuels, gasoline, lubricating oils, heavy oils, refined crude oil fractions, non-refined crude oil and fractions thereof.
Abstract:
A lubricant composition for the plastic working of metals that does not require a phosphate undercoating, is waterborne, requires only a simple application process of immersion or spraying followed by drying, and provides an excellent lubricating performance comprises synthetic resin, water-soluble inorganic salt, and water. The weight ratio of the content of salt to that of synthetic resin is from 0.25:1 to 9:1. This composition can also contain liquid and/or solid lubricating agent(s) and extreme pressure additive.

PCT No. PCT/CA97/00658 Sec. 371 Date Jun. 22, 1999 Sec. 102(e) Date Jun. 22, 1999 PCT Filed Sep. 11, 1997 PCT Pub. No. WO98/13445 PCT Pub. Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
Abstract:
Lubricating oils exhibiting anti rust properties are obtained by adding to the lubricating oil an acidic anti rust additive and an acid scavenger such as carbodiimide, in a specific sequence.
Abstract:
A stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 mu m to not more than 5 mu m. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 mu mRz, preferably from 1.0 to 10.0 mu mRz.
Abstract:
The present invention provides a method of stabilizing non-halogenated 3-isothiazolones in aggressive systems with pH above 8.5. The invention also discloses compositions with pH above 8.5, containing non-halogenated 3-isothiazolones and an effective stabilizing amount of a iodine-containing stabilizer.
Abstract:
Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A + B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.) + reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.
Abstract:
The invention concerns a lubricating composition, in particular for swaging, consisting of a suspension in water of a mixture of phospholipids and an organic or mineral basic compound. For example, the composition contains 80 wt.% water, 10 wt.% phospholipids brought in the form of soja bean lecithin, and 10 wt.% of calcium hydroxide or stearylamine as basic compound. Among other advantages the lubricant can be eliminated by means of an aqueous solvent, and is easily biodegradable.
Abstract:
A mould lubricant comprises a casting lubricant such as caster oil and a gaseous oxidation inhibiting agent such as sulphur hexafluoride (SF6). The mould lubricant can be used to lubricate a mould in the direct chill casting of a reactive metal such as magnesium.
