Abstract:
Provided are formulations, methods of making, and methods of using a diesel cylinder lubricating oil composition to achieve enhanced corrosive wear control on the cylinders of a 2-stroke diesel engine, wherein such lubricating oil composition comprises, among other things, an amount of one or more surfactant materials sufficient to provide substantially improved capacity to reduce or inhibit corrosive wear.
Abstract:
A hydrophilic composition for use with a lubricating system comprises hydrophilic fibers having a diameter between 50 nm and 10 microns and a length that is at least 5 times the diameter. The hydrophilic fibers having a strong affinity for at least one of water and other hydrophilic fluids and may remove or eliminate free or dissolved water in a lubricating system comprising at least one of an oil and a lubricating fluid.
Abstract:
A composition of biodegradable gear oil that mainly contains modified nontauedible vegetable oils. Mono-esters are hydrogenated, epoxidized or aryl alkylated or mixture thereof, and C7 to C12 primary alcohol. In addition to chemically modified non-edible vegetable oils, the composition also contains an additive pack, which comprises at least one: antioxidant, an extreme pressure additive, an anti foaming agent, a pour point depressant, a corrosion inhibitor and a detergent-dispersant additive. The product of this invention has utility as industrial and automotive gear oil GL 4 grade. The compositions are significantly biodegradable, eco-friendly, reduce use of petroleum, have lower cost than synthetic oil, are miscible in mineral & synthetic fluids and safe to use due to higher flash point.
Abstract:
The invention provides a lubricant composition for generating a combined passivate and lubricating coating on a metal substrate with which the composition is brought into contact. The lubricant composition comprises an organic polymer and/or a wax dispersion; phosphates, preferably acid phosphate salts, and/or phosphoric acid; and optionally, a surfactant, a thickening aid, an anti-wear additive, a defoaming agent; a corrosion inhibitor; and/or a linear or branched hydrocarbon.
Abstract:
In one aspect, a self-lubricating 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:
The invention concerns a threaded tubular component for drilling or working hydrocarbon wells, said tubular component having at one of its ends (1; 2) a threaded zone (3; 4) produced on its outer or inner peripheral surface depending on whether the threaded end is male or female in type, characterized in that at least a portion of the end (1; 2) is coated with a lubricating dry film (12) the matrix (13) of which comprises at least one migrating sliding agent (9) belonging to the oils or waxes family and principally distributed at the surface of the lubricating dry film (12) such that the coefficient of friction of the film (12) is less than 0.07 at loads of less than 40 N while the coefficient of friction of the film (12) is more than 0.1 at loads of more than 200 N.
Abstract:
The present invention provides a lubricating oil for a compression type refrigerator including a polyvinyl ether-based compound containing an alkylene glycol or polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a molecular weight in a range of 300 to 3,000; and an organic carboxylic acid ester of a polyhydric alcohol in which the ester contains two or more free hydroxyl groups. The lubricating oil for a compression type refrigerator of the present invention has high miscibility and high viscosity index, and is excellent in wear resistance and also corrosion prevention property under carbon dioxide atmosphere.
Abstract:
The invention relates to the defoaming of ionic liquids and also to compositions comprising at least one ionic liquid and at least one antifoam and, if appropriate, a solvent and/or further auxiliaries or additives.
Abstract:
The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
Abstract:
Water-based metalworking fluid contains: (A) alkanolamine represented by the following formula (1) and/or (B) alkanolamine represented by the following formula (2); and (C) 2-pyridylthio-1-oxide salt. In the formula (1): each R1 represents hydrogen or an alkyl group having 1 to 3 carbon atoms; n represents 2 or 3; and plural R1 may be mutually the same or different on condition that not all R1 represent hydrogen. In the formula (2): R2 represents an alkyl group having 1 to 10 carbon atoms; and Z1 and Z2 each represent an alkylene group having 2 to 8 carbon atoms.
