Abstract:
Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A + B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.) + reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.
Abstract:
A method of lubricating conveyor tracks or belts is herein described wherein the lubricant composition contains a polyalkylene glycol polymer and a fatty acid also described are methods of manufacture of such lubricant compositions in both concentrate and diluted form. The compositions may also comprise additional functional ingredients.
Abstract:
The present invention relates to a method for mechanically working of cobalt-containing metals or performing metalworking with a tool made of a metal containing cobalt. The method is carried out in the presence of an aqueous cooling lubricant containing a combination of an alkanolamine, a mono- or diphosphate ester and a mono- or dicarboxylic acid. The combination is capable of reducing both the release of cobalt ions and the corrosion of iron. In addition it also contributes essentially to the lubrication.
Abstract:
Solid anhydrous lithium hydroxide and lithium hydroxide polyolefin film which has a melting point below 280 °F and dissolves in hot lubrication oil with substantially no residue at low levels. More particularly, the pouches contain pre-measured amounts of lithium hydroxide monohydrate or lithium soap granules for use in the manufacture of lubrication grease compositions.
Abstract:
An aqueous working liquid composition for a wire saw comprising the following components (A) to (E): (A) 10 to 60% by weight of at least one selected from the group consisting of polyglycol ethers represented by the following formulae (I) and (II): R1-O-(CH2CH2O)n-R2 wherein R1 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or a phenyl group; R2 represents a hydrogen atom or an acetyl group; and n represents an integer of 1 to 4; (B) 0.1 to 5.0% by weight of at least one selected from the group consisting of organic bentonite and inorganic bentonite; (C) 0.01 to 5.0% by weight of at least one selected from the group consisting of carboxymethyl cellulose (CMC), MgO, methanol, and ethanol; (D) 0.1 to 2.0% by weight of at least one selected from the group consisting of a sodium beta -naphthalenesulfonate-formalin condensate and a sodium, potassium, lithium or amine salt of petroleum or synthetic sulfonic acid; and (E) 10 to 70% by weight of water, each based on the total composition weight.
Abstract:
The invention concerns a lubricating composition, in particular for swaging, consisting of a suspension in water of a mixture of phospholipids and an organic or mineral basic compound. For example, the composition contains 80 wt.% water, 10 wt.% phospholipids brought in the form of soja bean lecithin, and 10 wt.% of calcium hydroxide or stearylamine as basic compound. Among other advantages the lubricant can be eliminated by means of an aqueous solvent, and is easily biodegradable.

Abstract:
Adducts of clay, especially of the smectite variety, most especially bentonite, are prepared with an effective amount of at least one activated mixed metal oxide or oxy-hydroxide (AHMMO) formed by dehydrating hydrotalcite or a mixture comprising magnesium oxide and aluminum oxide, or a crystalline mixed metal hydroxide conforming substantially to the formula LimDdT(OH)¿(m+2d+3+n.a)(A?n)a.xH2O where m is zero to one, D is a divalent metal, d is from zero to 4, T is a trivalent metal, A represents at least one anion or negative-valence radical of valence n, where n is 1 or more, (m+2d+3+n.a) is equal to or greater than 3, (m+d) is greater than zero, and xH2O represents excess waters of hydration. These adducts are useful, e.g., in drilling muds and in viscosity modification of a wide variety of fluids.
