摘要： The invention relates to a device and a method for calibrating a blown film (6), said device comprising: a tubular region with at least one inner wall (55), through which region the blown film can be passed; a liquid reservoir (82), which can be used to provide a liquid and which is situated above the tubular region, the liquid being guidable between the inner wall (55) and the blown film; and a suctioning device (B), situated below the tubular region, for suctioning off at least part of the liquid from the blown film. At least one liquid-permeable element (92) is provided, said element surrounding at least parts of the periphery of the blown film (6). This device permits the distance of the liquid-permeable element from the main axis of the blown film to be altered.

摘要： A method of forming a finished film comprising extruding a molten polyethylene comprising a diene terpolymer modifier through a die opening to form a film, wherein the diene-terpolymer modifier is a terpolymer comprising ethylene-derived units, C3 to C10 α-olefin derived units, and diene-derived units; causing the film to progress in a direction away from the die opening; cooling the film at a distance from the die opening, the distance adjusted to allow relaxation of the molten polyethylene prior to solidification and/or crystallization upon cooling; and isolating a finished film therefrom. Desirably, the polyethylene is a linear low density polyethylene, and the die and cooling is suitable for forming a blown film.

摘要： A blown film extrusion system, comprising a circular die (10) for creating a tube of molten plastic which is blown into a bubble (30). A Cooling stack (1) is provided in the center of the circular die (10), within the bubble (30) in use, the Cooling stack (1) including an integrated IBC exhaust stack (24). Air from within the bubble (30) is drawn into an air inlet manifold (180) and spun to a high velocity into a substantially conical air distributor (150). This causes the air to be forced against the surfaces of the copper tubes (92) causing transfer of heat from the air to the tubes. The air is then expelled at the bottom of the Cooling stack (1) back into the bubble (30), where it rises back up to cool the inner surface of the bubble (30), before being drawn back into the air inlet manifold (180) for re-cooling.

摘要： A composite pipe comprises a polyetheretherketone innermost pipe around which a reinforcing overwrap is arranged. A protective sheath surrounds the overwrap. Such a composite pipe may be made by selecting a polyetheretherketone pipe having an outer region having a crystallinity of less than 25%; overlaying the selected pipe with overwrap; and subjecting the combination to heat, thereby causing the crystallinity of the outer region of the polyetheretherketone pipe to increase. The method reduces the risk of pipe failure.

摘要： The present disclosure relates to a composite pipe having improved bonding strength between heterogeneous materials, which provides continuous bonding strength by chemical bond between heterogeneous materials, thereby preventing separation between the heterogeneous materials even at a high temperature and a high pressure, so as to replace a metal-based pipe used in fields of industry demanding heat resistance and chemical resistance, and an apparatus and a method of manufacturing the composite pipe. Accordingly, strong bonding strength according to chemical bond in the unit of nano between the heterogeneous materials is achieved, so that separation between the heterogeneous materials is not generated even at a high temperature and a high pressure, thereby being capable of further expanding the applicable fields of industry.

摘要： The invention relates to a device for cooling and calibrating plastic profiled pieces, comprising a housing (13) that has an entry opening and an exit opening for the profiled piece (8) to be treated, and comprising a sleeve (12), which is placed inside the housing, connects the entry opening to the exit opening, and which surrounds a passageway (24) that essentially corresponds to the outer contour of the profiled piece (8) while enabling the profiled piece (8) to be guided therein. Said sleeve, in essence, completely surrounds the profiled piece in the area of the device. The inventive device also comprises a vacuum system for generating a vacuum inside the gap between the profiled piece (8) and the sleeve (12) that is connected to openings (14, 15), which have small dimensions and are provided in the sleeve (12). Finally, the device comprises at least one interior space (25), which is filled with a cooling medium when the device is in operation and which is connected to an inflow opening (17) and to an outflow opening (18) for a cooling medium in order to produce a flow of the cooling medium inside the interior space (25). An improved cooling capacity can be achieved by virtue of the fact that the sleeve (12) has at least one thin-walled section, which separates the passageway (24) from the interior space (25), and that openings (14, 15) are provided in this section that connect the passageway (24) to the interior space (25).
