Embodiment 1

[0103] An example of a method of coating an oxide containing silicon on a sliding surface of a blade will be described. Will image 3 The blades (SUS440C) that have been subjected to gas nitriding treatment in the form exemplified in , were ultrasonically washed with a mixed solvent of acetone and hexane at a mass ratio of 1:1 for 30 minutes, followed by ultrasonic cleaning with chloroform for 30 minutes, and then washed with 2- Ultrasonic cleaning with propanol for 30 minutes, and treatment with UV ozone cleaner for 30 minutes. The washed leaves were immersed in 34.8 parts of ethanol.

[0104] A solution of 0.54 parts of tetraethoxysilane (TEOS) and 17.8 parts of ethanol was prepared in a sample container with a lid, and a solution of 1.3 parts of 28% ammonia water and 17.8 parts of ethanol was prepared in another sample container and mixed. The washed leaves were added to the mixed solution together with 34.8 parts of ethanol, and reacted at room temperature (25° C.) for 2...

Embodiment 2

[0112] The initiator immobilized leaf was obtained by the same method as in Example 1.

[0113] In a glove box, 0.00026 parts of ethyl-2-bromo-2-methylpropionate, lauryl methacrylate (SLMA, BLEMMER manufactured by NOF Corporation) were added to a pressure-resistant container made of Teflon (registered trademark). SLMA-S) 36.1 parts, copper (I) bromide 0.21 parts, copper (II) bromide 0.014 parts, 4,4'-dinonyl-2,2'-bipyridine 1.2 parts, anisole 37.5 parts. Next, put the immobilized blade of the initiator into a pressure-resistant container and cover it, and perform SI-ATRP at 600C and 400MPa for 2 hours. After the polymerization, the blades were taken out from the polymerization solution, washed thoroughly with THF, and the blades with thick-film PLMA brushes were obtained.

[0114] For the polymerization solution after polymerization, carry out 1 H-NMR measurement and the molecular weight measurement utilizing the GPC method calculate the Mn and Mw / Mn of free PLMA, and the re...

experiment example 1

[0129] These two-layer separation temperature diagrams from -10°C to 60°C when using HFC410A as a refrigerant as a working fluid and refrigeration machine oil as a polyol ester as a lubricant are shown in Figure 6 middle.

[0130] Such as Figure 6 As shown in , in the temperature range of -10°C to 60°C, there is a region where the working fluid (refrigerant) and the lubricant (refrigerator oil) are separated into two layers, but in the lubricant relative to the working fluid and the lubricating oil When the ratio of the total mass of the agents is 60% by mass or more, there is always compatibility.

Abstract

The present invention provides a compressor capable of reducing the frictional loss of the sliding surface in the compression mechanism and reducing the leakage of the working fluid due to the improvement of the sealing performance without excessively improving the machining accuracy or assembly accuracy, and the compressor using the The refrigeration cycle device of the above-mentioned compressor. The compressor of the embodiment has a compression mechanism that sucks and discharges a working fluid, and a polymer brush is provided on at least one of a sliding surface or a sealing surface of the compression mechanism.

Description

[0001] This application is based on Japanese patent application 2017-193085 (the filing date is October 2, 2017), and the priority is enjoyed by this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiments of the present invention relate to a compressor and a refrigeration cycle device. Background technique [0003] For example, in a refrigeration cycle apparatus such as an air conditioner, a compressor such as a refrigerant compressor having a compression mechanism that sucks and discharges a refrigerant as a working fluid is used. To improve the efficiency of such a compressor, it is important to reduce the friction loss of the sliding part and the leakage loss of the working fluid from the gap of the sealing surface. If the gap between the sealing surfaces in the compression mechanism portion is reduced, the leakage amount of the working fluid can be reduced. However, high precision is required...
