摘要:
The invention relates to a method for the online monitoring of film quality during a production process for a plastic film, in particular a blown film or a continuously cast film, in which method the film material (1) is fed out of an outlet device (40) that is designed as a melt lug (4) by a transport device (10). The film material (1) cools on or in front of the transport device (10) and the film material (1) solidifies in front of or on the transport device (10).

A continuous flow dryer system according to various embodiments can include a source for supplying a material to be treated having a high moisture content, such as a distiller wet grain, a profile screw compression dryer, a profile screw, and a drive coupled to the profile screw for axially rotating the profile screw. The profile screw compression dryer includes an inlet for receiving the material for drying, which is fed therein in a controlled manner. The profile screw is provided within the housing of the dryer. The profile screw has a diameter that increases in dimension in a direction away from the inlet for increasing the compressive force applied to the material to assist with drying as the profile screw rotates and moves the material longitudinally along the profile screw to produce a final product, for example, a distiller dried grain for use as an animal feed.

A compression system includes a compression device and a controller. A treated material is pressed longitudinally through a compression chamber by simultaneously applying a lateral pressure and a two-dimensional cross-section compression which includes a pressure applied in a direction traverse to a direction of transport and a pressure applied in a direction parallel to the direction of transport. The controller controls the two-dimensional cross-section compression applied to the treated material such that, during compression, liquids in the treated material migrate to the outer surface of the treated material upon reaching the outlet orifice.

Silicone tube structures are formed having a particular dimensional accuracy. In one embodiment, a silicone tube structure can include an extruded hollow body having an inner bore. The extruded hollow body can have an inner diameter, an outer diameter, and a length of at least approximately 20 m. The extruded hollow body can also have a dimensional accuracy that is measured by the standard deviation of the inner diameter being no greater than approximately 0.8% of an average inner diameter of the extruded hollow body over the length. In an embodiment, the silicone tube structure can be cut to form a number of silicone tubes.

An object of the present invention is to provide a film that is used as one layer of a multilayer structure articles such as a laminated glass, and a solar cell module, and prevents the intrusion of bubbles and the generation of unfilled portions at the edge portions of the film; and a multilayer structure articles obtained with the use of the film. A polyvinyl acetal resin film, having a thickness distribution in the width direction of 10% or less, and a volatile matter content of 1.0 mass % or less, in which as to a portion of 5% of the total width inside from each of both edges in the width direction, when each portion is heated at 150° C. for 30 minutes, the larger value of the heat shrinkage in the flow direction that is parallel to the film and perpendicular to the width direction is referred to as heat shrinkage MD1, and the other value is referred to as heat shrinkage MD2, and when central portion in the width direction of the film is heated at 150° C. for 30 minutes, the heat shrinkage in the flow direction that is parallel to the film and perpendicular to the width direction is referred to as heat shrinkage MD3, all the heat shrinkage MD1, heat shrinkage MD2, and heat shrinkage MD3 are 3 to 20%.

摘要:
The production of a biaxially oriented tube from thermoplastic material, wherein a tube in preform condition is extruded from thermoplastic material using an extruder having an extruder die head with an inner die member that forms a lumen in the tube in preform condition. The tube in preform condition is subjected to a temperature conditioning. Use is made of a expansion device comprising a non-deformable expansion part having a gradually increasing diameter to a maximum diameter, which expansion part is contacted by the tube and exerts an expanding force so as to bring about expansion of the tempered tube in circumferential direction. The method comprises drawing the tempered tube over the expansion device using a drawing device, in such a manner that said tube is transformed from a tube in preform condition into a biaxially oriented tube with thermoplastic material which is oriented in axial direction and in circumferential direction of the tube.
