Abstract:
An aqueous cutting liquid comprises a cationic water-soluble resin having an amine value of 20 to 200 mgKOH/g, and at least one members of a rheology control agent selected from the group consisting of an inorganic bentonite, an organic bentonite and an aqueous silica sol, wherein the content of a nonvolatile matter of the rheology control agent is 0.1 to 30 percent by weight of the amount of the nonvolatile matter of the cationic water-soluble resin. An aqueous cutting agent comprises the aqueous cutting, and an abrasive grain, wherein the content of the abrasive grain is 100 to 1000 percent by weight of the amount of the nonvolatile matter of the aqueous cutting liquid. A hard and brittle material is cut by a cutting device using the aqueous cutting agent. The present invention provides an aqueous cutting agent which is excellent in dispersion stability of the abrasive grain and viscosity stability during cutting/cutting operations, aqueous cutting liquid usable for the aqueous cutting agent, and a cutting/cutting method excellent in cutting performance, cleanability and the like of the work material on cutting/cutting hard and brittle material by using the cutting agent.
Abstract:
A novel organophilic clay gellant comprising the reaction product of: (a) a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of natural clay without impurities; (b) a first organic cation in an amount of from about 75% to about 150% of the cation exchange capacity of the smectite-type clay; (c) a second organic cation provided by a polyalkoxylated quaternary ammonium salt; and (d) one or more organic anion(s) that is capable of reacting with said first and second organic cations, to form an organic cation-organic anion complex with said smectite-type clay. The organophilic clay gellant is used in a non-aqueous fluid system such as paints, inks, and coatings to provide improved rheological properties.
Abstract:
A grease composition for use as a cable filling material which contains about 75 to 95 parts by weight of a base component of a liquid or semi-solid polyol having a molecular weight of at least 4000 and a reduced amount of mono-unsaturated compounds, about 1 to 15 parts by weight of a thickening agent such as colloidal particles of silica, and between 1 and 5 parts by weight of an antioxidant. Optionally, a thermoplastic elastomer can be added to improve bleed resistance.
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:
A water-soluble cutting fluid is produced by dissolving a polymer fatty acid triglyceride imidazole, 2-methyl-1-stearate, and boric acid imidazole in the dispersion of inorganic bentonite in water thereby preparing a main component and adding oleic acid (agent for enhancing the lubricity), Na salt of ethylenediamine tetraacetic acid (metallic ion adsorbent), benzotriazole (rust-preventing auxiliary agent), and a silicone type defoaming agent to the main component.

Abstract:
An electroviscous fluid prepared by dispersing fine solid particles in an electrically insulating fluid. The fine solid particles have a specific gravity equal to, or greater than, that of the elctrically insulating fluid, and have a hydroxyl group on the surface thereof. The hydroxyl group is covalently bonded to a nonionic surfactant having a hydroxyl group and/or an -NH group as a hydrophilic group through a silane coupling agent, or polystyrene is covalently bonded thereto. The fluid is excellent in response, reproducibility, durability and thickening effect, particularly in dispersibility and shelf life stability, and can be utilized for electrical control of vibration control machines such as variable damping dampers, engine mounts, bearing dampers, clutches, valves, shock absorbers, precision equipment, acoustic instruments, etc., and for display devices.
