Abstract:
A coating and bonding composition is disclosed. The composition includes suspending, bonding and thinning agents, and a metallic flake. The composition may be used with an environmentally friendly lubricating composition to form an environmentally friendly lubricating system for protecting threaded connections from galling or other damage. That system may be used in a method for protecting threaded connections that includes the steps of: coating me threads, prior to make-up, with the coating and bonding composition and then coating them with the environmentally friendly lubricating composition, after the coated threads have dried.
Abstract:
A permanent mold casting powdery mold releasing agent according to this invention consists of a granulated or powdery mixture of a lubricant, an organic polymer and a metal soap; wherein the lubricant is coated with the organic polymer or the metal soap. Therefore, the mold releasing agent allows productions of castings of high quality, in a parmanent mold casting work, with good workability and without worsening environmental situations.
Abstract:
A lubricant to be sprayed onto the surface of a steel material for forming a lubricant coat on the surface of the steel material to be forged. The lubricant comprises a particulate lubricant composed of thermally melting resin mixed with inorganic lubricant. The particulate lubricant is applied onto the surface of a steel material to be forged. Before or after applying the particulate lubricant onto the surface of the steel material, the surface of the steel material is heated. Consequently, the thermally melting resin melts and coheres with the inorganic lubricant over the surface of the steel material, resulting in the formation of a uniformly thick lubricant coat over the steel material. The lubricant coat prevents the steel material from being burnt in a forging device even during hot forging. The lubricant coat is fit for the forging of hard to work steel material. The lubricant coat also contributes to the decrease in forging cost, without deteriorating the forging environment.
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:
Sulfurized propylene based lube olefin derivatives are superior lubricating fluids with internal synergistic multifunctional extreme pressure/antiwear and antioxidant properties as well as multifunctional extreme pressure/antiwear additives for both mineral and synthetic lubricating oils as well as fuels.
Abstract:
Novel aqueous lubricant dispersions contain at least one rare earth halide, e.g., cerium trifluoride, and at least one polymeric dispersing agent therefor, such at least one dispersing agent including:(a) a copolymer of an ethylenically unsaturated carboxylic acid or derivative thereof with an .alpha.-olefin comonomer and/or a vinyl comonomer;(b) a homopolymer or copolymer of an ethylenically unsaturated carboxylic acid or derivative thereof;(c) a copolymer of at least one ethylenically unsaturated carboxylic acid and at least one ethylenically unsaturated sulfonic acid comonomer; and/or(d) a polymer of an alkylene oxide of an (arylalkyl)phenol, or phosphated or sulfated derivative thereof.
Abstract:
A solid lubricant combination comprising (a) 25 to 65 parts by weight graphite, (b) 15 to 45 parts by weight zinc sulfide, (c) 5 to 20 parts by weight antimony (III) sulfide, and (d) 5 to 20 parts by weight of an alkali earth metal phosphate, or other inorganic metal phosphate or mixtures of such phosphates which are commonly known as solid lubricants, is described. The solid lubricant combination is especially suitable as an additive to friction linings and results in an improvement in their tribological properties.
Abstract:
Asbestiform crystalline calcium M phosphate, where M is sodium or lithium, having a length to average diameter ratio of at least 5:1, can be prepared by forming a melt of a source of oxygen, calcium, phosphorus and M having a mole ratio of about 15 percent to about 30 percent M.sub.2 O, about 48 percent to about 60 percent P.sub.2 O.sub.5 and about 20 percent to about 37 percent CaO, cooling the melt within the range of about 500.degree. C. to about 750.degree. C. for a sufficient time to permit blocks of calcium M phosphate to form, and fiberizing the blocks into the asbestiform crystals. Such asbestiform crystalline calcium M phosphates are useful to prepare composites of organic polymeric materials.
Abstract:
[Task]In a sliding member comprising a substrate and a coating layer provided thereon, the coating layer has a sliding surface and is formed of a resin-based coating and particles of a solid lubricant dispersed therein. The orientation ratio of (001) plane of the solid lubricant is enhanced.[Means for Solution]The coating layer of a sliding layer has an average thickness of 3 μm or less. The particles of the solid lubricant have 2 μm or more of an average particle diameter as measured by the laser diffraction method. The solid lubricant dispersed has 90% or more of relative C-axis intensity ratio.
