摘要： Provided is a pregrouted PC steel material comprising a PC steel stranded wire composed of a plurality of steel wires, a pregrout layer disposed on the outer periphery of the PC steel stranded wire so as to accommodate the PC steel stranded wire, a sheath covering the outer periphery of the pregrout layer, and a capsule including a pregrout-hardening agent and a film with which the agent is covered, the capsule being interposed among the steel wires constituting the PC steel stranded wire. The capsule has a strength such that the capsule is not broken before tensioning the PC steel stranded wire but is broken by a tensile force during the tensioning. Also provided is a method for hardening the pregrout layer.

摘要： An object of the present invention is to provide a polyimide tube for a fixing belt, the polyimide tube having good toner fixability. A polyimide tube for a fixing belt of an image-forming apparatus according to the present invention includes a polyimide layer that contains a polyimide as a main component and a needle-like filler, the needle-like filler containing a carbon nanotube and needle-like titanium oxide. A product of a thermal diffusivity (m2/s) of the polyimide layer and a breaking elongation (%) of the polyimide layer in an axial direction is 35×10−7 or more. An orientation direction of the needle-like filler is preferably an axial direction or a circumferential direction.

摘要： A pregrouted PC steel material (10) includes a 19-wire-twisted PC strand (1), a pregrouted layer (2) disposed on an outer periphery of the PC strand (1), and a sheath (3) configured to cover an outer periphery of the pregrouted layer (2). A filling resin (4) is filled between steel wires (side wires) (1b, 1c, 1d). Since the filling resin (4) does not exude to the pregrouted layer (2) before tensioning of the PC strand (10), an operation of tensioning the PC strand (1) is not hindered by curing of the pregrouted layer (2). In contrast, since the gap between the steel wires is reduced when the PC strand (1) is tensioned, the filling resin (4) flows out (exudes) from between the steel wires to the pregrouted layer (2) to cure the pregrouted layer (2) only after the reduction.
