This invention provides a reinforcing film that exhibits mild peel resistance in the initial stage of adhesion to an adherend, followed by a significant increase in adhesive strength, and possesses flexural recovery and flexural retention properties. The reinforcing film includes an adhesive layer. The adhesive layer comprises a polymer (A) and a polymer (B). The polymer (B) comprises monomer units having a polyorganosiloxane backbone and (meth)acrylic acid monomer units. Furthermore, the adhesive layer has a surface elastic modulus of 1–20 kPa at 23°C. Moreover, the polymer (B) has a weight-average molecular weight of 10,000–100,000.

The application provides a surface treatment device and a use method thereof. The surface treatment device comprises a casing, a wax feeding mechanism installed on the casing and used for accommodating and quantitatively pushing a wax stick, a waxing disc detachably installed on one side of the casing and abutting against the wax stick and used for receiving wax material and applying the wax material to a workpiece surface, an elastic pre-pressing coating head installed between the wax feeding mechanism and the waxing disc and used for pressing the wax stick towards the waxing disc, and a driving mechanism installed on the casing and in driving connection with the wax feeding mechanism and the waxing disc. The driving mechanism drives the wax feeding mechanism to adjust a contact surface of the wax stick relative to the waxing disc. The application solves the technical problem that in the prior art, the contact cross section of the wax stick and the waxing disc remains unchanged and the contact pressure is difficult to flexibly adjust according to wax stick consumption or wax material characteristics.

The present invention provides a highly conductive irregularly shaped gasket and a method for manufacturing the same, which is free from metal contamination, exhibits low deformation and low rebound. [Solution] The metallic foil 11 is made of a specific metal that does not cause metal contamination, including aluminum, and is configured as a rectangular thin film whose longitudinal size corresponds to the longitudinal size of the insulating fabric, and is provided on the surface of the rectangular insulating fabric 10. The elastic member 12 is configured as an elongated shape whose longitudinal size corresponds to the longitudinal size of the insulating fabric, and has an irregular cross-sectional shape that bulges upward from the bottom surface. In the irregular gasket of the present invention, one end of the insulating fabric in the short direction is attached to the lower surface of the elastic member in the short direction, the back surface of the insulating fabric is attached to the surface of the elastic member, and the other end of the insulating fabric in the short direction is attached to the elastic member, so that the metallic foil is continuously arranged from the upper surface to the lower surface of the elastic member in the short direction via the insulating fabric.
