Abstract:
A carrier-free pulverulent metalworking lubricant composition. In one preferred form, the composition contains at least two lubricant components one of which comprises a resin having a highly polar functional group the composition being formed by a method comprising the steps of: (a) forming a dry mixture of said particulate lubricant components, and (b) agglomerating said admixture to form agglomerated particles. The application of the composition as a metal working lubricant significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.
Abstract:
This invention provides a coating for zinc coated steel surfaces and other zinc containing alloys, including zinc/iron, zinc/nickel, zinc/cobalt, zinc/aluminum, and any other suitable metal surface. The coating product of this inventions contains the following ingredients: copolymers made from acrylic, vinylacrylic, and acrylstyrene monomers, has carboxylic radicals from acrylic and/or methacrylic acids, and has an Ia of 30 to 60 mg. of KOH. The water soluble copolymers and lubricatory additives, which include natural or synthetic waxes, graphite, and molybdenum sulfide, are in solid form dispersed in aqueous solution at a ratio of from 1 to 10%.
Abstract:
In a method of lubrication between two sliding members at least one of which is made of a ceramic material, the improvement according to the present invention is characterized in that soot as produced by burning a hydrocarbon fuel is supplied between the two sliding members.
Abstract:
A die-casting powdery mold releasing agent according to this invention is a mold releasing agent comprising a mixture of powdery or granulated mold releasing base material composed of an inorganic compound as used for lubricant in a solid form and an organic compound giving adhesive property to the mold releasing agent, the both having powdery or granulated configurations, or configurations in which the organic compound is covered on the mold releasing base material. The mold releasing agent allows production of castings of high quality, in the die-casting method with good workability and without worsening environmental situations.
Abstract:
A lubricant composition comprised of (A) fatty acid, (B) polytetrafluoroethylene fluorocarbon resin powder (C) pyrogenic amorphous silica powder and (D) carrier. The lubricant is prescribed for use with a pneumatic tire and wheel assembly containing a run-flat device. The lubricant is contemplated as a component in such an assembly.
Abstract translation:一种用于热加工的粉末润滑剂组合物,其包含无水五水合物或十水合物形式的硼酸钠和脂肪酸的钠盐或钙盐,并且还含有碳酸钙或碳酸锂作为润滑剂助剂。 由于这种构成,在管形成步骤之后以无定形形式固化的硼酸钠(Na 2 B 4 O 7 O 7)是 防止吸收水分,干燥并进行结晶反应。 因此,可以抑制最终产品管的沉积以Na 2 B 4 N 7 H 5 H 5的形式沉积在硼酸钠中, SUB> 2 O> O。 因此可以消除白鳞的产生。 此外,润滑剂组合物在正在加工的作业的那些表面上具有优异的扩散性,因此可以延长芯棒的寿命。 因此,润滑剂组合物可以广泛用作通过芯棒式无缝管轧机轧制生产无缝管中的最佳粉末润滑剂。
Abstract:
The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The undesired size ranges can be readily recycled because the agglomerates with untreated binder can be reprocessed, thereby promoting high recovery rates.
Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.
