Abstract:
A lubricant is provided for use in hot working such as cross-roll rolling of a seamless steel pipe. It effectively reduces the friction coefficient between the working tools and the material under the hot work, thus extending the lives of the tools. The lubricant contains: (A) from about 10 to about 60 wt% of alkali silicate; (B) from about 1 to about 20 wt% of silane coupling agent; (C) from about 0.1 to about 5.0 wt% of at least one kind of alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid; and (D) from about 30 to about 70 wt% of water. Alternatively, the lubricant contains: (A) from about 10 to about 60 wt% of alkali silicate; (B) from about 1 to about 20 wt% of silane coupling agent; (C) from about 0.1 to about 5.0 wt% of at least one kind of alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid; (D) from about 5 to about 50 wt% of water; (E) from about 10 to about 60 wt% of iron oxide; and (F) from about 0.1 to about 5.0 wt% of at least one additive selected from a group consisting of a dispersant and a thickening agent.
Abstract:
A dilatancy liquid is a sol under a low shear stress and a gel under a high shear stress, and includes inorganic particles having a roundness of 1.1 or less, and a particle diameter of from 0.05 to 5 µm, and a liquid held among the inorganic particles. The dilatancy liquid is of high mechanical strength, and exhibits a low viscosity under a low shear stress and a high viscosity under a high shear stress; namely: it exhibits a large viscous-resistance variation by a shear-stress increment.
Abstract:
Alkaline diamine track lubricants for use with glass, aluminum and two-piece PET containers and other articles of manufacture are prepared from an admixture of an alkyl diamine and a water-soluble hydrotrope. The diamine lubricants are prepared without the neutralization thereof and have a corrosion inhibitor which is, preferably, a reducing agent and a biocide incorporated thereinto. A source of alkalinity may be employed, as well, to maintain the pH above 8.
Abstract:
A method of lubricating plastic conveyor tracks or belts is herein described wherein the lubricant composition contains a block copolymer of ethylene oxide and propylene oxide; also described are methods of manufacture of such lubricant compositions in both concentrate and diluted form. The compositions may also comprise an anionic and a nonionic surfactant as well as a neutralizing agent.
Abstract:
A thermoplastic compatible lubricant concentrate containing alkylpolyglycoside suitable for use in lubricating conveyor belts in the transporting of thermoplastic article of manufacture. The hydrophobic group of the alkylpolyglycoside is a long chain alkyl group having 5 to 30 carbon atoms. The degree of polymerization of the saccharide units in the polyglycoside is less than 3.
Abstract:
Stress cracking in poly(alkylene terephthalate) articles of manufacture is inhibited by applying to the article a stress crack inhibitor which contains an amine having at least 6 carbon atoms. In a preferred embodiment, the stress crack inhibitor is applied to the article in the form of an aqueous fatty acid-based lubricant.
Abstract:
Amine-free cooling lubricants contain as essential component sets of anticorrosive substances, besides the usual base oils, emulsifiers and solubilizers. These sets of anticorrosive substances consist of a mixture of dimeric fatty acids and one or several carboxylic acids. The latter are selected among the apliphatic and aromatic carboxylic acids. Alkali metal, magnesium and/or calcium salts of said acids may be used in a similar manner. These amine-free cooling lubricants have an anticorrosive effect comparable to that of alkanolamine-containing cooling lubricants.
Abstract:
Primary amines having the formula R(OCH2)nCH(OH)CH2NH2 in which R is an acyclic group with 2-12 carbon atoms and n is 0 or 1, or a salt thereof, are used as anticorrosion and antimicrobial agents. They are suitable to be incorporated in aqueous, alkaline, industrial fluids. An aqueous, alkaline metal working fluid is also disclosed.

Date Nov. 28, 1991.A flame retardant grease composition comprising a lubricating base oil, a thickener selected from a simple or complex soap of lithium, calcium or sodium, and a flame retardant additive selected from an oxide, hydroxide, carbonate, bicarbonate, hydrogen carbonate or sulphate of an alkali metal or alkaline earth metal, for example calcium oxide, potassium carbonate, potassium hydrogen carbonate or potassium sulphate, or a mixture of two or more thereof.
Abstract:
A water-glycol hydraulic fluid comprising a higher aliphatic acid in a ratio of 2 to 15% by weight, alkali hydroxide in an amount less than an equivalent amount of the higher aliphatic acid, and an organic alkaline compound containing nitrogen atoms in an amount sufficient to adjust the pH of the whole fluid to 10 to 12 is desclosed. This hydraulic fluid has excellent wear resistance and also excellent sludge solubility.
