Abstract:
The fluid compositions of the present invention include an glycol component that includes a mixture of glycols according the formula: Wherein, typically, at least one of R2, R3, R4 and R5 is an alkyl group. The physical properties of the compositions include a high dry equilibrium reflux boiling point (ERBP), a high wet equilibrium reflux boiling point (WERBP), a low temperature viscosity or any combination thereof. These compositions are particularly useful because their physical properties (e.g., WERBP, ERBP, and low temperature viscosity) meet or exceed the provisions for DOT 3, 4, or 5 brake fluids.
Abstract:
Bei der Bearbeitung von Metallen werden Schmiermittel benötigt, die bei hohen Verarbeitungstemperaturen ein optimales Gleiten des Metalls zwischen den Verarbeitungswerkzeugen gewährleisten. Die Aufgabe der vorliegenden Erfindung besteht darin, ein grafithaltiges Schmiermittel zur Verfügung zu stellen, welches trotz unverminderter Schmierwirkung den Verkokungseffekt im Werkzeug minimiert, das Werkzeug schützt und die Werkzeugstandzeiten wesentlich erhöht. Die vorliegende Erfindung betrifft ein Hochtemperaturschmiermittel, insbesondere Gesenkschmiermittel, auf Basis von in Wasser dispergiertem Grafit oder auf Basis von Grafit in Mineralöl, welches 0,01 bis 5 Gewichtsprozent (Gew.-%) mindestens eines Oxidationskatalysators, vorzugsweise einer Cer-Verbindung sowie TiO 2 , MnO 2 , Ferrocen, Eisentallat und/oder Fe(OH) x , enthält sowie ein Verfahren zum Warmumformen von Metallen unter Verwendung des erfindungsgemäßen Hochtemperaturschmiermittels.

The lubricant comprises a molybdenum amine compound obtained by reacting a compound containing a hexavalent molybdenum atom with an amine represented by the following formula (1): where each of R to R represents a hydrogen atom and/or a hydrocarbon group having one or more carbon atoms, and at least one of R to R is a chain hydrocarbon group having 14 or more carbon atoms, or the following formula (2) wherein R represents a chain hydrocarbon group having 10 or more carbon atoms, s represents 0 or 1, X and/or Y represents a hydrogen atom, a hydrocarbon group having at least one carbon atom, an alkanol group having 2 to 4 carbon atoms or an alkyl amino group having at least one carbon atom, and X and Y are not hydrogen atoms or hydrocarbon groups at the same time when s is 0. A lubricating composition containing the lubricant is also provided.
Abstract:
A lubricant in the form of an oil- insoluble solvent e.g. water in oil emulsion is described where a water soluble or water dispersible base is present in the dispersed phase. These lubricants are beneficial in various applications such as internal combustion engines where the oil desirable has enough basicity to neutralize any inorganic acids generated by sulfur present in the fuel.
Abstract:
An aqueous lubricant used for plastic working of metallic material which comprises (A) a water soluble inorganic salt, (B) lubricative agent selected from molybdenum disulfide and graphite and (C) wax, wherein the components are dissolved or dispersed in water, and wherein a concentration ratio (weight ratio) of (B) /(A) is in the range of 1.0∼5.0 and (C) / (A) is 0.1∼1. 0. And a method of lubricative film processing on a metallic material, in that the lubricative film formed by applying the aqueous lubricant is in a dried weight of 0.5∼40g/m 2 . A water soluble inorganic salt (A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdete and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70∼150°C. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of a metal having no chemical conversion layer formed thereon.

The composition comprises (a) an oxyethylated aliphatic alcohol whose aliphatic hydrocarbon moiety contains 18 or more carbon atoms and (b) dissolved phosphate anions. Preferably the composition also comprises inorganic boron, an alkali metal salt of a fatty acid, and an accelerator for phosphate coating.
Abstract:
A metal-working water or a metal-working composition which has excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A metal-working water containing sodium ion and one or more kinds selected from the group consisting of fluoride ion, hydrogencarbonate ion and silicon and being adjusted to pH 6.0 to pH 10 can be used as a substitute for a conventional cutting oil. A metal-working composition including a metal-working water with such additive as a rust-preventive agent and being adjusted to pH 6.0 to pH 10 can also be used.
