Abstract:
An aqueous lubricant used for plastic working of metallic material which comprises (A) a water soluble inorganic salt, (B) lubricative agent selected from molybdenum disulfide and graphite and (C) wax, wherein the components are dissolved or dispersed in water, and wherein a concentration ratio (weight ratio) of (B) /(A) is in the range of 1.0 SIMILAR 5.0 and (C) / (A) is 0.1 SIMILAR 1. 0. And a method of lubricative film processing on a metallic material, in that the lubricative film formed by applying the aqueous lubricant is in a dried weight of 0.5 SIMILAR 40g/m . A water soluble inorganic salt (A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdete and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of a metal having no chemical conversion layer formed thereon.
Abstract:
A rolling bearing which has a satisfactory life at a low cost even under such service conditions that water is incorporated into a lubricant either externally or due to dew condensation, or that vibration has an influence, and is particularly suitable for electrical equipment and accessories of automobile engines, such as alternators. The hydrogen ion index pH of a grease scaled in the interior of the bearing is adjusted to 7 to 13. For attaining similar effects, the pH of the grease is adjusted to 5 to 13 when an organic metal salt or ADTC has been added in a predetermined amount to the grease, when an inorganic compound having an average particle diameter of not more than 2 Ám has been added in a predetermined amount to the grease, or when a diurea compound containing an aromatic amine or a mixture of diurea compounds has been added as a thickening agent to the grease.
Abstract:
PROBLEM TO BE SOLVED: To obtain a two-pack type anti-seizing agent for hot plastic working, in which since an anti-seizing agent applied to a disk roll type guide shoe is not made to flow by cooling water of a roll, the anti-seizing agent is supplied and retained on the peripheral surface of the disk roll type guide shoe, is not adhered to the roll and does not cause a roll slip between the roll and a tubular material and the tubing material is punched and rolled and to provide a method for producing a seamless pipe using the same. SOLUTION: The two-pack type anti-seizing agent comprises a first aqueous solution that contains 10-30% by mass calculated as an anhydride of sodium silicate when the mass of the total of the first aqueous solution is 100% by mass and a second aqueous solution containing one or more kinds selected from the group consisting of an organic acid, its water-soluble amine salt, an inorganic acid, its water-soluble amine salt, a water-soluble amine, a water-soluble alcohol and a water-soluble metal chloride.

Abstract:
An oil-soluble reaction product of phosphorus-, low molecular weight basic nitrogen-, and optional boron-containing compounds is provided. This reaction product can solubilize significantly more phosphorus and boron per weight of compound than other known compounds and is used as an antiwear, antioxidant, and extreme pressure additive in lubrication oils.
Abstract:
An aqueous functional fluid composition free of formaldehyde and formaldehyde producing agents, more especially an aqueous metalworking fluid composition, having improved resistance to attack by microorganisms is provided. This fluid comprises a) water, b) a water soluble or dispersible functioning agent (e.g. water soluble or dispersible organic lubricant) and c) an antimicrobial effective amount of the combination of d) a water soluble or dispersible nitrogen bearing organic compound (e.g. monoethanolamine) and e) a water soluble or dispersible haloalkynylalkyl carbamate (e.g. 1-iodo-3-propynylbutyl carbamate).
Abstract:
PROBLEM TO BE SOLVED: To provide a protective film treating agent capable of forming, by a simple method for attaching it to the surface of a metallic material and then drying, a film having excellent seizing resistance and excellent rust prevention which are equal to or higher than the film formed by a chemical treatment method. SOLUTION: The protective film treating agent is obtained by incorporating an alkali silicate to be represented by the formula: M 2 O.nSiO 2 [wherein n is a number of 2-9; and M is at least one kind of Na, K, Li, and NR 4 (wherein R is an alkyl group)] into water. The incorporation of a lubricating component into this protective film treating agent can impart excellent self-lubrication performance to a film. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a steel wire or a steel wire material showing an excellent lubricity, which is obtained through an easy process wherein a phoshorus-free aqueous treatment liquid is applied to a material to be coated via soaking or spraying, and is uniformly coated, without any deposition blotch, with a coated film having an excellent lubricity and baking resistance equivalent to or higher than those of composite films obtained by applying a soap onto a phosphate film. SOLUTION: The steel wire or the steel wire material showing an excellent lubricity is manufactured by forming a lubricating coated film essentially comprising a potassium salt of boric acid, a polyethylene wax having an average particle size of ≤1 μm and a synthetic hectorite of the formula: [Si 8 (Mg a Li b ) O 20 (OH) c F 4-c ] - XNa + X (wherein 0
