摘要:
A cooling, lubricating and cleaning agent, for use by the metalworking industry, produced by the condensation reaction between an excess amino alcohol with boric acid and the addition of a carboxylic acid to the complex boron containing diamine formed in the reaction system.
摘要:
An improved lubricating oil composition comprising a major amount by weight of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount of an oxidized olefin polymer which has been reacted with an aliphatic amine or polyamine. Preferably, this reaction occurs in the presence of a formaldehyde-yielding reactant. This composition provides improved inhibition of sludge and varnish formation in use.
摘要:
Lubricant compositions comprising an oil of lubricating viscosity and a minor proportion of water containing in an amount sufficient to counteract the accelerating effect of water on metal fatigue an amine salt of a half-ester of a substituted succinic acid. Greases containing the above-described amine salts are also provided.
摘要:
A composition and method of preparation are herein described for molten release and parting compositions adaptable for use in glass-forming operations. The novel composition comprises an aqueous dispersion of a mixture of a solid lubricant, a water-soluble silicate binder, a setting agent, and a water-soluble phosphate. A preferred composition comprises a mixture of flake graphite, boron nitride, sodium silicate, zinc oxide and potassium phosphate tribasic.
WHERE R1 AND R2 ARE BYDROGEN OR METHYL; R3 AND R4 ARE EACH AN INDEPENDENTLY SELECTED ALKYL GROUP HAVEING FROM 1 TO 20 CARBON ATOMS; R5 IS THE ORGANIC RESIDUE EXCLUSIVE OF REACTIVE HYDROXYL GOUPS OF A POLYOL, P IS AN INTEGER OF FROM 2 TO 6 INCLUSIVE AND N AND M ARE POSITIVE INTEGERS INDEPENDENTLY SELECTED IN EACH CHAIN AND WHOSE SUM IN EACH CHAIN IS FROM 2 TO 20, ARE PREPARED BY SUCCESSIVELY REACTING BORIC ACID WITH A GLYCOL MONOETHER AND A POLYOL. THESE ESTERS ARE USEFUL AS STABILIZERS AND CORROSION INHIBITORS FOR LUBRICANTS AND NON-AQUEOUS HYDRAULIC FLUIDS.
摘要:
Aqueous compositions, useful per se as lubricants or for forming dry lubricating films, comprising a finely divided solid lubricant suspended in an aqueous solution of an alkali metal silicate and an alkali metal lignosulfonate. Methods for making such compositions and for coating metal fasteners therewith. Metal fasteners lubricated with such compositions.
摘要:
A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
摘要:
A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.
摘要:
The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.
