摘要： A method of manufacturing PET nurdles comprises the steps of grinding a plurality of recycled PET bottles into a group of polymer flakes and of washing the group of polymer flakes to remove at least a portion of one or more contaminants from a surface of the flakes. The group of flakes comprises a first plurality of flakes that consist essentially of PET and a second plurality of flakes that do not consist essentially of PET. The method comprises the steps of scanning the washed group of flakes to identify the second plurality of flakes, and of separating the second plurality of flakes from the first plurality of flakes. The second plurality of flakes is molten to produce a polymer melt; via providing an extruder that extrudes material in a plurality of different extrusion streams; via reducing a pressure within the extruder to between about 0 millibars and about 25 millibars; while maintaining the pressure within the extruder between about 0 millibars and about 25 millibars, passing the polymer melt through the extruder so that the polymer melt is divided into a plurality of extrusion streams, each having a pressure between about 0 millibars and about 25 millibars. After passing the polymer melt through the extruder, the polymer melt is filtered through at least one filter. The polymer melt is then pelletized to form a plurality of PET nurdles.

摘要： A continuous kneading device (1) includes a pair of kneading rotors (3), being capable of increasing mesh between the kneading rotors (3) while suppressing a kneading load applied to the kneading rotors (3). The continuous kneading device (1) includes a barrel (2) and a pair of kneading rotors (3) housed in the barrel (2) and rotating in mesh in directions different from each other. Each kneading rotor (3) includes a plurality of kneading flights (11, 15) for kneading a material supplied into the barrel (2). The kneading flights (11, 15) and respective portions of the barrel (2) housing the kneading flights (11, 15) respectively configure a plurality of kneading sections aligned axially of the kneading rotors (3). The material is fed axially from the upstream kneading section to the downstream kneading section to be sequentially kneaded. The kneading flight (15) constituting the downstream kneading section has a rotational outer diameter (D2) larger than a rotational outer diameter (D1) of the kneading flight (11) constituting the upstream kneading section.

摘要： A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder (10) is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section (12) of the modified planetary roller extruder (10), conveying the raw materials from the feeding section (12) to a compounding section (14) of the modified planetary roller extruder (10), continuously mixing the primary raw materials in the compounding section (14) to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section (14) of the modified planetary roller extruder (10) includes a main spindle (26) surrounded by and intermeshed with a plurality of planetary spindles (28, 30) at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights.

摘要： Provided is a kneading degree adjusting apparatus, which can have a wide adjusting range for a kneading degree even if a gate member and a cylindrical segment are not made so close as to invite a fear of metallic contacts. The kneading degree adjusting apparatus is disposed in a kneading treatment equipment, which includes a cylindrical segment formed at a predetermined portion and a kneading screw for kneading a material while feeding the same to the downstream side, thereby to adjust the kneading degree of the material. The kneading degree adjusting apparatus comprises a gate member having an opposed face confronting the outer circumference of the cylindrical segment and moved toward and away from the outer circumference of the cylindrical segment thereby to change the area of the material passage to be formed between the opposed face and the outer circumference of the cylindrical segment. The outer circumference and the opposed face are corrugated to form the passage into a bent shape.

摘要： A cylinder 2 is formed with an upper guide bore 10a and a lower guide bore lOb at a position corresponding to a gate part B. Gate rods 7 are rotatably inserted through the guide bores 10a, lOb respectively. Each of the gate rods 7 is formed with opening degree changing recesses in a form of an opencut adjacent to each other in an axial direction in order to constitute opening degree variable channels S in combination with opening degree variable channel forming parts 14 of two screws 3. Each of the recesses 11 consists of a first semicircular face 12 and a second semicircular face 13 in such a shape that an upstream side end of the first semicircular face 12 is diagonally cut. By rotating the gate rods 7 in a positive and a reverse directions, the opening degree can be changed between a fully opened state wherein the first semicircular face 12 and the opening degree variable channel forming part 14 are in parallel and a fully closed position wherein the second semicircular face 13 is in abutment against the opening degree variable channel forming part 14.
