Abstract:
Carbon fluoride particles in which a number-average particle size is 0.01 to 50 .mu.m, a content of particles having such a diameter that the particles size distribution falls with in range of the number-average particle size .+-.20% amounts to at least 50% of the whole, a true specific gravity is 1.7 to 2.5, a F/C as a whole is 0.001 to 0.5, and a F/C at the surface is always larger than the F/C as a whole and is 0.1 to 2.0. These carbon fluoride particles are obtainable by reacting carbon particles with fluorine at 350.degree. to 600.degree. C. for one minute to six hours. These carbon fluoride particles have an excellent dispersibility and a powder flowability, and are usable solely or in the form of composite, as water- and oil- repellents, non-tackifying agents, solid lubricants, agents for imparting electric conductivity, additives to toner for developing electrostatic image, additives to coating of carrier for developing electrostatic image, composite materials for fixing roller, phosphoric acid fuel cells, zinc/air batteries and nickel/hydride storage batteries.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds (.alpha.-PFCs) having the general formula C.sub.n F.sub.2n+2, perfluoromorpholines having the general formula C.sub.n F.sub.2n+1 ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
Abstract:
Aluminum or aluminum alloy substrates are coated with primer coating chemicals and topcoating chemicals for forming a cured primer coat having lubricating and hydrophilic properties. The primer coating chemicals contains a thermosetting water-soluble or water-dispersible resin component (A), and the topcoating chemicals contains a resin component (C) containing a carboxymethylcellulose derivative and N-methylolacrylamide. At least one of them further contains a lubricant (B) selected from the group consisting of a higher aliphatic acid lubricant and an inorganic lubricant.
Abstract:
Friction modifiers are composition which modify the coefficient of friction between surfaces to which the friction modifier is applied. They are similar in nature to lubricants but have different characteristics in certain respects. The invention relates particularly to solid friction modifiers which may be rigid or flexible. These friction modifiers comprise 20-80% by weight of a polymer medium, 5-20% by weight of a solid lubricant and 15-60% by weight of a friction enhancer. The composition produces a coefficient of friction which rises to above 0.20 at creepage level up to 2.5% between steel bodies in rolling-sliding contact lubricated using the composition.
Abstract:
Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.

A composite, multilayer thin film solid lubricant structure having multiple thin film layers of solid lubricant interleaved by thin film interlayers which interrupt propagation of growth defects in the deposition process.
Abstract:
A metal-free lubricant composition for use in threaded tube and pipe connections includes graphite and a substantially nonabrasive, friction increasing adjusting component, both dispersed in a lubricant base material in which a polyalkylene is dissolved, with the graphite being present in an amount effect to decrease a coefficient of friction of said composition, the friction increasing adjusting component being present in an amount effective to increase the coefficient of friction of the composition, and the polyalkylene being present in an amount effective to enhance formation of graphite flakes from graphite particles upon application of pressure. The lubricant composition can provide corrosion resistance as well as similar or superior lubricating properties in comparison to conventional metal-containing grease compositions.
Abstract:
This invention pertains to a novel lubricant composition which possess high and positive friction characteristics. A high, positive friction lubricant composition comprising: (a) at least 20% by weight of a polymer media; (b) at least 5% by weight of a solid lubricant; and (c) at least 5% by weight of a powderized solid mineral friction modifier.
Abstract:
A lubricant composition for use in threaded tube and pipe connections comprises from 10 to 70% by weight of pure, crystalline, graphite and from 0.1% to 10% by weight (calculated of graphite) of a special additive in the form of strongly polarizable or ionizable organic compounds like e.g. amines, amine salts, metal-amine complexes, combinations of amines with polymers, polymeric amines, ammonium compounds, alkylsulphates, organic phosphates, phosphonates and sulphonates. The balance is formed by a supporting vehicle such as an oil or grease. In this composition, the performance characteristics of the graphite have been improved by the special edditive such that it can be used for lubricating and sealing threaded tube and pipe connections under conditions of extreme pressure.
