Abstract:
A system generally comprises a first conveyor including a receptacle configured to receive a photovoltaic (PV) cell module preassembly; a vacuum applicator; a pressure applicator; a curing applicator; and a second conveyor; wherein the second conveyor is arranged opposing the first conveyor to seal the receptacle, and configured to function as a press bladder for the pressure applicator; wherein the vacuum applicator, the pressure applicator, and the curing applicator are configured to respectively process the PV cell module preassembly at spatially distinct positions of the receptacle; wherein the first or second conveyor is configured to transport the receptacle from position to position from the vacuum applicator to the pressure applicator and from the pressure applicator to the curing applicator; and wherein the system is configured and operable to form a cured PV cell module. A method employs the system to press cure PV cell module preassemblies to prepare cured PV cell modules.
Abstract:
The present invention pertains to a process for manufacturing a film of ultra-high molecular weight polyolefin comprising the steps of subjecting a starting ultra-high molecular weight polyolefin with a weight average molecular weight of at least 500 000 gram/mole in powder form to a compacting step using an isobaric press, subjecting the compacted polyolefin to a rolling step and at least one stretching step under such conditions that at no point during the processing of the polymer its temperature is raised to a value above its melting point. The process allows for the manufacture of ultra-high molecular weight polyolefin films of high quality.
Abstract:
Die Erfindung betrifft eine Doppelbandpresse (1) mit zumindest zwei Bändern (2, 3) zum Verpressen eines Presslings (18), wobei die Doppelbandpresse (1) zumindest einen Verdichtungsbereich (5) aufweist, wobei der Verdichtungsbereich (5) zwischen einem isochoren Betrieb mit einem vorgegebenen Abstand zwischen den beiden Bänder (2, 3) und einem isobaren Betrieb mit einem vorgegebenen, von den Bändern (2, 3) auf den Pressling (18) auszuübenden Druck umschaltbar ist.

Die Erfindung betrifft eine Doppelbandpresse (1) mit zumindest zwei Bändern (2, 3), wobei die Doppelbandpresse (1) zumindest einen Verdichtungsbereich (5) und zumindest einen isobaren Pressbereich (6) aufweist, wobei der Verdichtungsbereich (5) und der isobare Pressbereich (6) in einer Förderrichtung der Doppelbandpresse (1) hintereinander angeordnet sind, wobei der isobare Pressbereich (6) in Förderrichtung des Substrates vor dem Verdichtungsbereich (5) angeordnet ist.
Abstract:
An apparatus and process for producing a resin-impregnated cured sheet which comprises continuously curing a continuous uncured fibrous sheet obtained by forming short fibers into a sheet and impregnating it with an uncured resin; and an apparatus and process for producing a carbonaceous material sheet which comprises continuously carbonizing the cured sheet. The carbonaceous material sheet is excellent in handleability and transportability and is capable of being wound. The continuous uncured fibrous sheet (1a) is conveyed by a conveying means comprising at least one pair of rotating belts (2) each comprising a drive roll (2a), a driven roll (2b), and an endless belt (2c) running on and between these rolls, and the resin is cured between heating/pressing rolls or between the endless belts. The resultant resin-impregnated cured sheet is then continuously conveyed in a horizontal direction to a carbonization chamber and carbonized therein to produce a carbonaceous material sheet.
