Water-based metalworking fluid contains: (A) alkanolamine represented by the following formula (1) and/or (B) alkanolamine represented by the following formula (2); and (C) 2-pyridylthio-1-oxide salt. In the formula (1): each R1 represents hydrogen or an alkyl group having 1 to 3 carbon atoms; n represents 2 or 3; and plural R1 may be mutually the same or different on condition that not all R1 represent hydrogen. In the formula (2): R2 represents an alkyl group having 1 to 10 carbon atoms; and Z1 and Z2 each represent an alkylene group having 2 to 8 carbon atoms.
摘要:
An extreme pressure agent and a friction coefficient modifier which comprises a compound having, in a molecule, a group represented by general formula (I): wherein R1, R2, and R3 each represents hydrogen atom or methyl group, and at least one of R2 and R3 represents hydrogen atom; a fluid resistant to seizure under load and a wear resistant fluid which each comprises the above additive or the above modifier; and a flame resistant fluid which comprises a thermally polymerizable substance, preferably the above compound. The extreme pressure agent and the friction coefficient modifier have excellent properties and are advantageously used for lubricating oil, metal working oil, and hydraulic oil. The flame resistant fluid suppresses vaporization of flammable substances by thermal polymerization to prevent fire when the fluid is exposed to a high temperature and is advantageously used as lubricating oil, metal working oil, hydraulic oil, heat treatment oil, and grease.
摘要:
An aqueous heat treatment liquid composition exhibiting a favorable rust resistance with a high cooling capability and a high uneven-cooling resistance is provided. The aqueous heat treatment liquid composition contains a hyperbranched polyglycerol. A mass average absolute molecular weight of the aqueous heat treatment liquid composition is preferably in a range of 5,000 to 500,000. When the aqueous heat treatment liquid composition is used for quenching of a metallic component, the aqueous heat treatment liquid composition can exhibit a favorable rust resistance with a high cooling capability and a high uneven-cooling resistance.
摘要:
Provided is a lubricant for metal working comprising a vinylidene compound having 12 to 64 carbon atoms obtained by oligomerizing α-olefins, having 4 to 20 carbon atoms, using a metallocene catalyst. The lubricant for metal working is excellent in a workability and a surface detergency property and has a high flash point and can reduce environmental pollution.

Provided is a water-based lubricant comprising a hyperbranch-type polyglycerol having an absolute molecular weight of from 5,000 to 500,000. The water-based lubricant has a small friction coefficient and is excellent in lubrication performance and defoamability, as compared with conventional water-based lubricants comprising an ethylene/propylene oxide copolymer, and is favorable, for example, for a water-based metal processing agent and a hydraulic pressure fluid.
摘要:
A method of reduction reclamation of an oil or prevention of oxidation degradation of the oil of the present invention includes: using an electrolytic cell 13 having an anode 11 and a cathode 12 made of a hydrogen storage material, and inside of the cell divided by the cathode 12 into an electrolytic chamber 13A and a reduction chamber 12A; supplying the oil to the reduction chamber 12A while applying an electric voltage between the anode 11 and the cathode 12 to electrolyze an electrolytic solution supplied to the electrolytic chamber 13 (Translator's comment: correctly, 13A); and absorbing hydrogen generated on the cathode 12 in the electrolytic chamber 13A in the cathode 12 to reduce the oil in the reduction chamber 12A, the method for reduction reclamation of the oil or prevention of oxidation degradation of the oil allowing continuous treatment.
