A large-area wrinkled graphene substrate capable of being manufactured in a large-area, and a method for manufacturing the same is provided. A method for manufacturing a wrinkled graphene substrate includes: i) providing a graphene unit; ii) inserting a carrier film and a graphene unit between a pair of rolls and rotating the pair of rolls in opposite directions to attach a carrier film on the graphene unit, iii) immersing the graphene unit in an etching solution to provide graphene, iv) between a pair of rolls, graphene and poly(4-styrene sulfonic acid)/polystyrene (PSS/PS) substrate attaching graphene onto the PSS/PS substrate, v) attaching an ethylene vinyl acetate/polyethylene terephthalate (EVA/PET) substrate to wrinkled graphene on PSS/PS substrate by inserting EVA/PET and WGr/PSS/PS stack between the rolls, viii) removing the PSS/PS substrate by immersing PET/EVA/WGr/PSS/PS stack in water, and ix) providing a wrinkled graphene substrate on the EVA/PET substrate.

A process for forming a sleeve on a container including the steps of: providing a container; placing a shrink sleeve around the container; conforming the shrink sleeve to the container by shrinking the shrink sleeve; providing a predetermined removeable portion in the shrink sleeve; providing a striker moving tangentially relative to the predetermined removeable portion; and removing the predetermined removeable portion by contacting the striker to the predetermined removeable portion.

A method for joining or repairing a pipe system that comprises a least two pipes made of weldable plastic material, comprising: fitting a sleeve made of weldable plastic material the distance between the two pipes, the sleeve having a length A that exceeds the distance B between the mutually opposing pipes, such as to overlap each pipe end to a given extent C; placing an electrically conductive band around one of the pipes, the band having two ends; connecting the band ends to each other by placing the band ends overlapping each other; fitting the sleeve over and against the pipe and the band, and applying an electric current to the band over a given period of time, thereby heating the band to a determined temperature for a determined time and fusing the band with the plastic surfaces of the pipe and the sleeve lying in abutment therewith to form a welding joint being fully executed around the pipe and inside the sleeve.
摘要:
A heat shrink apparatus for heat shrinking a shrink film to a bladder. The heat shrink apparatus may include a support structure, a bladder support system, and a heat chamber. The bladder support system for supporting the bladder thereon may have two spaced apart parallel rows of a plurality of resilient members pivotally and/or resiliently attached to the support structure. The heat chamber may be hollow with opposing end openings and may have one or more heating elements therein. The heat chamber may translate over the shrink film and the bladder along the support structure between the two spaced apart parallel rows, shrinking the shrink film to the bladder. As the heat chamber translates, it may contact ends of the resilient members, thereby pivoting or deflecting the resilient members from a first position to a second position such that the heat chamber can pass between the two parallel rows.

A stretch composite fabric comprises a sintered expanded porous polytetrafluoroethylene film and a stretch cloth laminated to each other while maintaining a flat state. The stretch composite fabric has a tensile stress at 10% elongation, as measured in at least one direction, of 1.8 N/15 mm or less. When a 5 cm-width test piece of the stretch composite fabric is stretched in a length direction under a load of 300 g and then released from the stress, an elongation recovery R of the stretch composite fabric, which is given by the following equation, is preferably 70% or more. R=(L2−L3)/(L2−L1)×100 (In the equation, L1, L2, and L3 represent the lengths of the composite fabric before the load is applied, when the load is applied, and after the load is removed, respectively.)

摘要:
An improved fastener with an annular sealing flange disposed above a lead-in base clip portion adapted for insertion into an acceptance opening in a panel or other structure. A heat-shrunk seal is disposed about the perimeter of the annular sealing flange in partial covering relation to upper and lower surfaces of the annular sealing flange to provide an enhanced sealing relation between the sealing flange and the panel.

This invention is directed to multiple sealing bars to seal articles moving on a conveyor 2 inside a sleeve 4 that forms a continuous film tube 5. Retracting conveyors act to collapse the tube between the articles so that the collapsed portion of the tube can be sealed. The synchronization of the sealing bars with the movement of retracting conveyors allows for a continuous motion machine where the products inside the film do not stop.

The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

Hermetically sealed packages and hermetic seals based on oriented polymer films, such as oriented polyolefin polymers like biaxially oriented polypropylene (BOPP) and biaxially-oriented polyethylene terephthalatete (boPET). The films and seals are capable of providing high oxygen barrier properties effective for modified oxygen packaging.
