Abstract:
The invention concerns a composition for preparing metal products designed to be shaped by at least one mechanical process of plastic deformation such as wire drawing, rolling, calendering, forging, swaging and the like, without notable shrinkage of substance. The invention is characterised in that it comprises a film-forming binder, at least an additive reactive with the metal, at least a lubricating additive and at least an anticorrosive additive. The invention also concerns a method for preparing said metal products using the claimed composition.
Abstract:
A water soluble composition comprising a fluid concentrate comprising one or more compounds selected from the group consisting of amino acids, polyamino acids, phosphonates, benzotriazole and its derivative(s), carbonates, ortho- and polyphosphates, ortho- and polyborates, and polycarboxylic acids, mixtures thereof and the like in a form which forms a solid residue upon loss of water, particularly salt form, and a residue inhibiting composition selected from dihydric alcohols, polyhydric alcohols, a polymer(s) containing hydroxyl functional groups or mixtures thereof and the like, in an amount effective to inhibit formation of residues of said compounds is disclosed with a method of inhibiting residue formation during an operation using the above composition that has been diluted. Also disclosed are a metal working composition which comprises a metal working fluid concentrate containing metal working adjuvants in a form which forms solid residue upon loss of water, particularly salt form and a residue inhibiting composition selected from dihydric alcohols, polyhydric alcohols or mixtures thereof and the like in an amount effective to inhibit formation of a residue(s) of the metal working adjuvant(s), and a method of inhibiting residue formation during a metal working operation using the above metal working composition that has been diluted.
Abstract:
This invention relates to novel water soluble metal working fluid compositions, their use to work metal, a process for working metal using such compositions and the metal worked article of manufacture. More particularly, this invention relates to fluid compositions useful in cutting, grinding, shaping and other metal working operations which require a lubricant. The terms "first Group A" and "second Group B" are used herein to denote different groups and not to indicate any sequence of use or selection as any possible combination or sequence of use of a component(s) is envisioned without limit of any kind. The disclosed fluid compositions are also anticorrosive and environmentally more acceptable than current oil based fluids. There has now been discovered an essentially odorless, substantially non-oil misting, water-soluble metal working fluid comprising at least one component selected from a first Group A herein and optionally one or more components selected from a second Group B herein preferably with the balance of the composition being water and other (optional) minor ingredients. When a component is employed from Group A and a component is employed from Group B the action of the combination generally enhances performance of the resulting combination with contain moieties from both Group A and Group B.
Abstract:
There are disclosed improved water-soluble metal working fluids comprising polyaspartic acid, amides and salts thereof, a corrosion inhibitor(s) and a basic additive said additive having sufficient basicity and buffering power to maintain the pH of the composition above about 8.5 and preferably above about 9. Such compositions are useful as lubricants in processes to cut, bend, grind and shape both ferrous and non-ferrous metals and tend to maintain higher pH values due to the incorporation of a basic additive. The polyaspartic acid and salts thereof are particularly advantageous in that the fluids can be easily disposed of after use without special treatment because polyaspartic acid and salts thereof are readily biodegradable.
Abstract:
Alkaline diamine track lubricants for use with glass, aluminum and two-piece PET containers and other articles of manufacture are prepared from an admixture of an alkyl diamine and a water-soluble hydrotrope. The diamine lubricants are prepared without the neutralization thereof and have a corrosion inhibitor which is, preferably, a reducing agent and a biocide incorporated therein to. A source of alkalinity may be employed, as well, to maintain the pH above 8.

Abstract:
A solid lubricant additive for resin-bound friction lining mixtures is characterised in that it contains a combination of copper-I-sulphide (Cu2S) with at least another sulphide of molybdenum, zinc, antimony, wolfram, tin and/or titanium.
Abstract:
A process is provided for preventing grease fires, which is particularly useful in steel mills and process mills. In the process, when a flame is ignited and approaches a special grease, the special grease emits carbon dioxide to extinguish the flame and prevents combustion of the grease.
Abstract:
A lubricant additive that includes antimony thioantimonate and antimony trioxide in a specified ratio for enhancing the extreme pressure, antiwear, and antiabrasive properties of conventional lubricants as well as for use in lubrication of a wide variety of lubricated contact surfaces.
Abstract:
The pasty damping agent is used to damp mechanical and/or acoustic oscillations. The agent contains as a minimum compound a solid finely divided substance or a mixture of solid finely divided substances, as a liquid phase, a silicone oil, a polyglycol, a mineral oil and/or a saturated or aromatic aliphatic carbon dioxide ester, an agent for increasing the activity of the limit layer or a surfactant, a magnesium and/or aluminum silicate and/or a silicon dioxide finely divided as a viscosity stabilizer and possibly a small quantity of an empty oxidiser. The damping agent is used in different hydraulic damping devices or for industrial vibration shock absorbers.
