摘要:
A lithium-ion secondary battery with good cyclability by suppressing the active material from coming off or falling down from the current collector. It is characterized in that the lithium-ion secondary battery comprises a binder comprising a cured substance of alkoxy group-containing silane-modified polyamic acid resin which has a structure being specified in the application as Chemical Formula 2 wherein R1 is 3,3',4,4'- biphenyltetracarboxylic dianhydride residue and R2 is 4,4'-diaminodiphenyl ether residue.
摘要:
A swash plate (10) is operably connected through a lug plate (11) and a hinge mechanism (12) to a drive shaft (9), and slidably retained on an end part of each piston (8). through a pair of front and rear shoes (15a, 15b). A rotational motion of the swash plate (10) following rotation of the drive shaft (9) is converted through the shoes (15a, 15b) into a reciprocating motion of each piston (8). A thermoplastic polyimide coating (17) is formed on the swash plate (10) and the shoes (15a, 15b) as sliding components of a compressor (C). The thermoplastic polyimide coating (17) may contain a solid lubricant. For the solid lubricant, for example, polytetrafluoroethylene is used. Thus, it is possible to obtain a compressor, which includes the sliding components having improved sliding characteristics, and is manufactured relatively easily.
摘要:
A compressor has a swash plate and shoes. Surfaces of the swash plate slides on flat surfaces of the shoes. A sliding film is formed on each of the swash plate surfaces. The sliding films are formed of a polyamide-imide resin that contains at least solid lubricant. The polyamide-amide resin has a tensile strength at room temperature of 200 MPa. The isocyanate component, which is a crude material of the polyamide-imide resin, contains 5 % to 90 % by mol of 3,3'-dimethylbiphenyl-4,4'-diisocyanate. The number average molecular weight of the polyamide-imide resin is no less than 20,000. When a base portion of the swash plate is made of an aluminum-based metal, the sliding films are formed on the base portion with middle layers made of anodized aluminium in between.
摘要:
A coating composition for use in sliding members contains a polyamideimide resin and a solid lubricant and is prepared by mixing these ingredients. The polyamideimide resin is a substance having a glass transition temperature of 270°C or above or a substance having a tensile strength of 200 MPa or more at room temperature. The sliding film made of the coating composition for use in sliding members is provided with a satisfactory sliding property.
摘要:
A compressor includes a swash plate, and a shoe connected to an outer periphery of the swash plate. A surface of the swash plate slides upon a flat surface of the shoe. A sliding film is applied to the surface of the swash plate. The sliding film is formed of binder resin which contains a solid lubricant and titanium oxide powder. This allows the surface of the swash plate and the flat surface of the shoe to smoothly slide upon each other.
