The present invention provides a highly stable HFO refrigerant composition for use in a vapor compression-type refrigeration system, having improved slidability for the sliding portions of the vapor compression-type refrigeration system. More specifically, the present invention provides an HFO refrigerant composition comprising at least one type of HFO refrigerant and a polymer of halogenated propene represented by C 3 H a F b Cl c (provided that a + b + c = 6, a = an integer of 1 to 3, b = an integer of 3 to 5, and c = an integer of 0 to 1) that is an oligomer having a molecular weight of 200 to 900.

摘要:
A lubricant system is disclosed that is formed by contacting a fibrous network with oil and/or lubricating fluid having an affinity for the fibrous network. The fibrous network comprises oleophilic fibers having a diameter between 50 nm and 10 microns and a length that is at least times the diameter. In addition, the oleophilic fibers have an affinity for the oil and/or lubricating fluid.
摘要:
The lubricating oil composition of the invention comprises a lubricant base oil, a 3,4,5-trihydroxybenzoic acid ester at 5-5000 ppm by mass, and a phosphorus compound at 0.001-10.0% by mass, based on the total mass of the lubricating oil composition. The lubricating oil composition of the invention significantly lowers wear and exhibits a stable low frictional coefficient, while having a high rust-preventing effect for iron-based sliding sections. The lubricating oil composition of the invention is therefore suitable for prolonged use, and exhibits a notable effect for energy savings as well due to its stable low frictional coefficient property.
