摘要:
A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.

When a bridge pier is reinforced or repaired by wrapping a reinforcement around the pier, a waterproof sheet having a sufficient flexibility to attach to and cover the interface between the pier and the reinforcement in a liquid-tight manner is useful. The waterproof sheet is attached to the interface between the pier and the reinforcement to prevent water from penetrating into the interface for thereby preventing the reinforcement from deterioration.

A carpeted surface is protected with a temporary carpet protection sheet that includes a lightweight non-woven or knit fibrous material laminated with a resin backing into which at least portions of fibers of the fibrous material are embedded, or to which resin of the fibers is directly and chemically fused. Male touch fastener elements extend along the backing and are arranged in spaced apart fastening regions adjacent the longitudinal edges of the fibrous material. The male touch fastener elements are configured to be both releasably engageable with the hook-engageable fibers of the fibrous material, when the protection sheet is arranged in overlapping fashion, and releasably engageable with looped carpet tufts. A protection system features multiple lengths of such protection sheet joined by hook seaming tape.

This invention relates to a method of manufacturing a thermal laminate by laminating a first substrate film layer and a second substrate film layer through an adhesive resin layer, which involves the steps of, integrating the adhesive resin layer with the first substrate film layer, heating the surface of the adhesive resin layer by heat rays in the presence of oxygen to induce functional groups which contribute to adhesion, and then, superimposing the second substrate film layer on the adhesive resin layer to be bonded thereto with pressure. The thermal laminate has a strong laminated strength without using a solvent, and is excellent in the safety and hygiene of foods.

In the manufacturing method of the laminated metal plate, a fluorine resin film is used as a plastic film. Prior to a flame treatment, a joint surface of the metal plate is heated with a direct flame of 900° C. to 1200° C. for 1 to 5 seconds so that the joint surface is preheated to 40° C. to 70° C. After that, the joint surface of the metal plate is heated to 250° C. to 450° C. by the follow-on flame treatment.
摘要:
The invention relates to a method for melting a thermoplastic plastic material, particularly for welding plastic parts, wherein the plastic is heated by means of heat radiation via a radiation body (4) and simultaneously by the application of a hot gas, wherein the invention provides for the radiation body (4) to be heated on the interior thereof by burning a combustion gas, and for the exhaust resulting from the burning to be applied to the plastic material.
