Abstract:
In one aspect, a self-lubriating component is provided for a pharmaceutical packaging assembly. The self-lubricating component comprises a polymer composition and an effective amount of a lubricating additive such as, for example, boron nitride. In another aspect, a pharmaceutical packaging assembly may be provided having a surface thereof coated with a lubricating composition comprising boron nitride. The pharmaceutical packaging composition may be, for example, a pre- filled syringe comprising a body (barrel) and a plunger assembly.
Abstract:
An aqueous coating composition for reducing friction and/or blocking at a surface, said composition comprising a solid lubricant and a modified or synthetic clay mineral having thickening properties such that a 2% by weight aqueous dispersion of the modified or synthetic clay mineral thickener has a viscosity of at least 1000 mPa.s. Preferred clay minerals used as thickeners are preferably smectite clays such as saponite, hectorite, stcvensite, sauconite, bentonitc, beidellite, nontronite, or montmorillonite.
Abstract:
The object of the invention is a method and an apparatus for lubricating a rope laid from wires in the manufacturing phase of the rope. By means of the invention lubricant, e.g. lubricant (5) containing solid substances such as grease, a grease compound or a paste, is spread onto at least one wire (1) of each strand of the rope to be laid. The lubricant (5) to be spread onto the wire (1) is dispensed onto the endless surface (10) moving in a different direction with respect to the direction of movement of the wire (1) and is conveyed on the aforementioned endless surface (10) into contact with the wire (1).
Abstract:
The present invention relates to additives for use in lubricant compositions to processes for producing the additives, and to the use of the additives in lubricants and in systems that are lubricated. More specifically, the additive includes a capped particle (10) comprising: (i) one or more core particles (20) wherein the core particle is an inorganic particle having a dimension less than about 5 µm; and (ii) one or more multi-block copolymers (30) attached to the inorganic particles, wherein the multi-block copolymer comprises a) at least one nonpolar polymer block (51 ); b) at least one first polar polymer block (41 ); and c) at least one second polar polymer block (42); wherein the nonpolar polymer block is interposed between the first polar polymer block and the second polar polymer block, the first polar polymer block is attached to the core particle, and at least a portion of the second polar polymer block is not attached to the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece (60), the capped particle preferably adhere to the metallic surface of the workpiece.
Abstract:
A metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair. The salts and oxides contribute to the formation of the ceramic -metal layer.
