Abstract:
A metal working process employs a metal working fluid which is water-based and which is one of neutral and basic, the metal working fluid including a corrosion inhibitor in an amount ranging from 0.1 to 10% by weight; a lubricant selected from the group consisting of mono- or dicarboxylic acids or esters thereof having more than 10 carbon atoms, organic phosphate esters containing one or two hydrocarbon groups having 6-18 carbon atoms, and nonionic alkylene oxide adducts having a molecular weight above 400, and mixtures thereof; and an antimicrobially active amount towards fungi and bacteria of at least one alkanolamine compound having the following general formula (I) wherein R is an acyclic hydrocarbon group having 8-14 carbon atoms, A is an hydroxyalkyl group having 2-4 carbon atoms, and X is one of hydrogen. The at least one alkanolamine compound prevents microbial degradation of water-based fluids when included therein.
Abstract:
Die Erfindung betrifft ein pastenartiges Dämpfmedium, das zur Dämpfung von mechanischen und/oder akustischen Schwingungen geeignet ist. Das pastenartige Dämpfmedium enthält als Mindestbestandteile einen feinverteilten Feststoff bzw. ein feinverteiltes Feststoffgemisch und als Flüssigphase ein Silikonöl, Polyglykol und/oder einen gesättigten, aliphatischen oder aromatischen Carbonsäureester. Bei Verwendung von Polyglykol oder eines Carbonsäureesters als Flüssigphase ist es von Vorteil, ein Mittel zur Erhöhung der Grenzflächenaktivität (Netzmittel) und feinverteilte Magnesiumsilikate, Aluminiumsilikate und/oder feinverteiltes Siliziumdioxid als Viskositätsstabilisatoren und gegebenenfalls geringe Zusätze eines Antioxidationsmittels als Mischungsbestandteil zu verwenden. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung der pastenartigen Dämpfmedien und die Verwendung der pastenartigen Dämpfmediun in den verschiedenartigsten hydraulisch wirkenden Stoß-und Schwingungsdämpfern.
Abstract:
Compositions of 1,3,5-tris-(furfuryl)hexahydro-s-triazine are useful as antimicrobial agents particularly when added to metal-working compositions subject to fungal and bacterial attack.
Abstract:
The invention relates to the use of at least one selected polyhydroxy compound in lubricant formulations and the use of chain lubricants which contain at least 20 percent by weight of a selected polyhydroxy compound, for reducing the friction between transported goods and transport installations. The invention also relates to a lubricant which contains further additives in addition to the polyhydroxy compounds.
Abstract:
Solid anhydrous lithium hydroxide and lithium hydroxide polyolefin film which has a melting point below 280 DEG F and dissolves in hot lubrication oil with substantially no residue at low levels. More particularly, the pouches contain pre-measured amounts of lithium hydroxide monohydrate or lithium soap granules for use in the manufacture of lubrication grease compositions.
Abstract:
Lubricating solutions are seud on conveying system in the beverage industry during the filling of containers with dairy products or other beverages. Lubricating compositions of the present invention, especially those designed for use in heavy load bearing conveyors such as those in the dairy industry conveying systems for contained beverages, comprise at least the following components: (a) an alkyl alkoxylated (e.g., ethoxylated or propoxylated, preferably ethoxylated) phosphate ester, (b) a secondary alcohol alkoxylate, (with an optional aryl [e.g., aromatic, such as phenol] alkoxylated [e.g., ethoxylated or propoxylated] phosphate ester), (c) an aromatic or linear quaternary ammonium antimicrobial agent, and (d) a liquid carrier, such as water. These lubricating solutions are capable of providing good lubricity and antimicrobial activity over a prolonged time and under high stress and heavy loads.
Abstract:
A multi-purpose thread compound comprises, dispersed in a supporting vehicle, an extreme pressure agent, and particulate material comprising graphite and a calcium and/or magnesium inorganic salt, wherein substantially all the particulate material in the composition has a particle size of no greater than 50 mu m.
