A composition for coating steel wire to facilitate the cold drawing thereof, said composition comprising: (A) from about 50 to about 99.99 % by weight of a component selected from the group consisting of Na2SO4, K2SO4, and mixtures thereof; (B) from about 0 to about 49.99 % by weight of a component selected from the group consisting of Na2B4O7, NaBO2, K2B4O7, KBO2 and mixtures of any two or more thereof; and (C) from about 0.01 to about 5 % by weight of a component selected from the group consisting of potassium soaps, sodium soaps, and ammonium soaps; wherein the percentages by weight are based on the total weight of components A, B, and C in the composition, and wherein not more than 50 % by weight of the total of sodium plus potassium plus ammonium ions in components A, B, and C of the composition consists of sodium ions.
摘要:
A rheologically controlled glass lubricant for hot metal working comprises a glass powder, a binder, a rheological agent, and a weetting and viscosity modifier. These materials may be dispersed in a carrier. The lubricant is made by mixing the constituent elements, milling the mixture, and stabilizing the milled mixture. The lubricant can be used in a forging operation by coating a metal part with the lubricant, heating the coated part, placing the coated heated part in a forge, and rapidly applying sufficient pressure to deform the coated metal part into a desired shape.

Beschrieben wird eine Hochtemperatur-Schraubenschmierpaste in Form einer homogenen Anteigung einer feinteiligen anorganischen Feststoffkomponente aus Zinndioxid als Festschmierstoff und einem mineralischen und/oder synthetischen Silicat als Füllstoff in einem Mineralöl und/oder Syntheseöl als Trägerkomponente und die Verwendung einer homogenen Anteigung einer feinteiligen anorganischen Feststoffkomponente aus Zinndioxid als Festschmierstoff und gegebenenfalls einem inerten, thermisch stabilen feinteiligen anorganischen Füllstoff in einem Mineralöl und/oder Syntheseöl als Trägerkomponente als Hochtemperatur-Schraubenschmierpaste.
摘要:
In einem Verfahren zur Erleichterung der Kaltverformung von Metallen wird ein Schmiermittelfilm aufgebracht, indem man zunächst auf die Metalloberflächen eine wäßrige Lösung oder Dispersion eines wasserlöslichen thermoplastischen Harzes mit einem Gehalt an Melamin!Cyanursäure- bzw. IsocyanursäureAddukt aufbringt und auftrocknet und anschließend mit Metallseife und/oder einem Schmieröl behandelt. Vorzugsweise enthält die wäßrige Lösung oder Dispersion Harz zu Addukt in einem Gewichtsverhältnis von 1 : 0,3 bis 1 : 2. Das Schichtgewicht des aufgetrockneten Harzfilmes sollte 0,3 bis 30 g/m 2 betragen.
摘要:
A refrigerant compressor comprises an electric component; and a compression component which is driven by the electric component and compresses a refrigerant. At least one of slide members included in the compression component is made of an iron-based material. An oxide coating film (150) is provided on a slide surface of the iron-based material, the oxide coating film including a first portion (151), a second portion (152), and/or a third portion (153). The first portion (151) contains at least fine crystals (155). The second portion (152) contains columnar grains (156). The third portion (153) contains layered grains (157).
