Abstract:
A metal-working water or a metal-working composition which has excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A metal-working water containing sodium ion and one or more kinds selected from the group consisting of fluoride ion, hydrogencarbonate ion and silicon and being adjusted to pH 6.0 to pH 10 can be used as a substitute for a conventional cutting oil. A metal-working composition including a metal-working water with such additive as a rust-preventive agent and being adjusted to pH 6.0 to pH 10 can also be used.
Abstract:
Silicone grease compositions are prepared by blending a thickening agent with a liquified crosslinked organosiloxane gel produced using a platinum-catalyzed hydrosilylation reaction. The gel is liquified by application of a shearing force to the crosslinked gel. The shearing force can be applied prior to and/or during blending of the gel with the thickener.
Abstract:
The present invention provides a grease composition excellent in both rust-proofing properties and safety. The grease composition comprises a lubricating base oil and a thickener, and further comprises a lipophilic organic inhibitor, a nonionic surface active agent and a hydrophilic organic inhibitor selected from the group consisting of lanolin fatty acid derivative and alkanolamine derivative modified with a hydrophilic group each in an amount of from 0.1 to 10% by weight based on the total weight of said grease composition.

Abstract:
The present invention provides a novel surface-modified inorganic substance obtained by modifying the surface of an inorganic nitride or an inorganic oxide with a boronic acid compound, and a heat dissipation material, a thermally conductive material, and a lubricant which use the surface-modified inorganic substance. The present invention also provides a method for manufacturing the surface-modified inorganic substance, and provides, as a novel method for modifying the surface of an inorganic substance selected from an inorganic oxide and an inorganic nitride with an organic substance, a method for modifying the surface of an inorganic nitride or an inorganic oxide with an organic substance that includes making a contact between the inorganic nitride or the inorganic oxide with a boronic acid compound.
Abstract:
Provided are spherical silicon oxycarbide particle material and manufacturing method thereof, wherein the average particle size is in the range of 0.1-100 μm and having a sphericity of 0.95-1.0.Spherical silicon oxycarbide particle material and manufacturing method thereof are provided as follows. Organotrialkoxysilane is hydrolyzed in a pH 3-6 acetic acid aqueous solution, thereafter an alkaline aqueous solution such as a pH 7-12 ammonia water was added to the obtained hydrolysate. The condensation reaction is performed in an alkaline range to form spherical polysilsesquioxane particles that are spherical silicon oxycarbide precursors that has no melting point or softening point. Sintering was then performed at a sintering temperature of 600-1400° C. under inert atmosphere to obtain spherical silicon oxycarbide particle material.

Abstract:
An exemplary embodiment is directed to an equipment lubricating composition comprising useful microorganisms. An exemplary embodiment comprises a water insoluble, water-absorbent substance and an encapsulated microorganism component including viable microorganisms. This encapsulating material may encapsulate and protect the microorganisms by essentially preventing the microorganisms from contacting the external environment. Based on the protection afforded by the encapsulation, exemplary embodiments may include previously inhospitable carrier compounds such as particulate machine lubricants.
