Abstract:
The present invention is, in one form, an aqueous alkaline metalworking fluid composition in the form of a concentrate which includes a salt of orthophosphoric acid; a dibasicdioic acid in an amount of up to about 5.0% by weight of the concentrate; an essentially phosphonate-free chelating agent; and, a neutralizing base. The composition may also include a lubricating agent, a coupling agent, a passavating agent, a biocide, and a colorant.
Abstract:
Die vorliegende Erfindung betrifft ein Schmiermittel-Additiv, umfassend a) 2,5 bis 30 Gew.-%, bezogen auf das Gesamtgewicht des Schmiermittel-Additivs, einer Schmierstoffkomponente, die ausgewählt ist unter Zinnsulfid (insbesondere Zinnmonosulfid (SnS), Zinndisulfid (SnS 2 ), Zinntrisulfid (Sn 2 S 3 ) oder Mischsulfide davon), Zinksulfid (ZnS), Bismuttrisulfid (Bismut-III-sulfid, Bi 2 S 3 ), aktiviertem Graphit und Gemischen davon; b) 0,1 bis 5 Gew.-%, bezogen auf das Gesamtgewicht des Schmiermittel-Additivs, eines Metallsulfids, das ausgewählt ist unter Molybdändisulfid, Antimontrisulfid, Wolframdisulfid, Kupfersulfid (CuS, Cu 2 S oder Mischsulfide davon), Eisensulfid (FeS, Fe 2 S 3 oder Mischsulfide davon) und Gemischen davon,
wobei das Gewichtsverhältnis von Komponente a) zu Komponente b) im Bereich von 2,5 : 1 bis 100 : 1 liegt. Das Schmiermittel-Additiv bewirkt eine hohe Stabilität der Suspension der Festschmierstoffe in einem Schmiermittel ohne die Schmiermitteleigenschaften nachteilig zu beeinflussen.

Abstract:
A metal working water-soluble lubricant composition comprising a water-soluble polymer compound whose counter anion is acidic phosphorus-containing compound or boric acid is disclosed. The water-soluble polymer compound is selected from the group consisting of cationic or amphoteric addition polymers, ring-opened polymers, polycondensation products and salts or quaternary ammonium salts of natural polymer derivatives having at least one basic or cationic nitrogen atom in one molecule thereof with a molecular weight of 1,000 to 10,000,000. The composition has a load resistance equal to or higher than known liquid lubricants which contain mineral oils, beef tallow etc., and shows an excellent lubricating performance when applied to a metal working surface.
Abstract:
A composition comprising : water; a surfactant or mixture of surfactants present in a concentration sufficient to form a spherulitic or dispersed lamellar phase in the absence of Electrolyte; and a substantially insoluble functional material, suspended in the composition; said composition being substantially free from Electrolyte.
Abstract:
An electro-rheological fluid comprises an electrically insulating liquid as the dispersion medium, a porous solid particulate material as the dispersed phase, at least one member selected from water and polyhydric alcohols, and at least one member selected from acids, bases and salts.
