Abstract:
A water-soluble metal-working lubricant composition comprising as essential components thereof(a) one or more polyetherpolyols having molecular weights of 200 to 100,000 and obtained by adding alkylene oxides to either one or more of compounds selected from(1) polyalkylenepolyamines and derivatives thereof,(2) alkyl- and alkylaryl-amines and derivatives thereof and(3) carboxylic acid amides and derivatives thereof; and(b) one or more compounds selected from phosphoric acid compounds and boric acid.Incorporation of a specific polyetherpolyol compound together with phosphoric acid compound or boric acid serves as alternative to conventional liquid oil-base lubricant with mitigating drawbacks such as poor stability of emulsions, fouling of surfaces, difficulty in waste water, etc., which are inherent in conventional lubricants.
Abstract:
Substantially oil-free aqueous industrial fluids comprise (A) up to as much as 99.9 percent by weight water, (B) at least one substantially water-insoluble functional additive stably dispersed in the water and (C) at least one substantially water-soluble liquid organic dispersing agent, said dispersing agent being capable of dispersing said functional additive in said fluid and are useful as liquids in a variety of industrial applications, such as hydraulic systems and metal shaping operations. Typically, these compositions also contain at least one water-soluble polymeric thickener and at least one corrosion inhibitor. Methods for preparing these fluids from concentrates are also disclosed.
Abstract:
Release and lubricating composition for avoiding seizure between molten glass and metal molds for forming glass articles, for minimizing wear between mold sections and for improving the pack of glassware, comprising, a dispersion of graphite in a polyphenylene sulfide, molds having such composition coated thereon, and a method of applying the composition to molten glass contacting surfaces comprising dispersing the composition containing graphite with the polyphenylene sulfide in the form of small particles in a carrier, applying the dispersed composition to the glass contacting surface and then curing the coating at an elevated temperature, including curing resulting from hot molds during glassware production.
Abstract:
The addition of a metal chromate or dichromate to a silicone lubricating grease reduces galvanic corrosion during the lubrication of dissimilar metal surfaces which are separated by a lubricating film of the grease.
Abstract:
A BRIGHT-FINISH WELD-WIRE FOR ELECTRIC WELDING PURPOSES AND THE METHOD OF MAKING SUCH WIRE WHICH INCLUDES CLEANING A LENGTH OF STEEL WIRE BY ACID-ELECTROLYTIC TREATMENT AND THEN COLD-DRAWING IT THROUGH A DIAMOND DIE USING AS
A WIRE-DRAWING LUBRICANT AN AQUEOUS SOLUTION OF WATERSOLUBLE SOAP AND A WATER-SOLUBLE INORGANIC RUST INHIBITOR.
Abstract:
THE REACTION PRODUCT OF HEXAFLUOROISOPROPANOL WITH MONOCYCLOHEXYLAMINE OR DICYCLOHEXYLAMINE, OR MIXTURES OF BOTH, HAVE BEEN PRODUCED. THESE REACTION PRODUCTS HAVE BEEN FOUND TO BE UNUSUALLY EFFECTIVE AS CORROSION INHIBITORS. THE REACTION PRODUCTS CAN BE USED ALONE OR CARRIED IN OR ON THE SURFACE OF PAPER, PL STICS, OR OTHER SOLID MATERIALS; THEY CAN BE ADDED TO HYDROCARBONS, OILS GREASES, HYDRAULIC FLUIDS AND OTHER LIQUID CARRIERS, EITHER IN SOLUTION OR IN SUSPENSION, AND THEY PRVENT RUSTING OF FERROUS METALS OR CORROSION OF OTHER METALS.
