    摘要： Methods and systems are disclosed for determining plastic components of a blended plastic material. According to a method of the present invention, a blending computer access supply data describing characteristics of each of a plurality of plastic components. The blending computer receives specification data which identifies at least one desired characteristic of the blended plastic material. The blending computer processes the supply data and the specification data to determine combinations of certain of the plastic components that may produce the blended plastic material having the at least one desired characteristic. The blending computer determines, for each combination, a preferred percentage of each of the plastic components of the combination, and reports the combinations and preferred percentages.

    摘要： An extrusion method and apparatus for removing volatile contents from solid state resin materials is described. A cascade-type extruding device is used having first and second extruders. A top end portion of the first extruder 10 is directly connected to a rear side portion of a cylinder of the second extruder 100. Volatile contents of a melted resin, which is melted when the solid state resin material is supplied to the first extruder, are removed in a volatile content removing vacuum unit provided on an upstream side of the connection between the first and second extruders. The melted resin is then extruded from a nozzle provided at a top end portion of the second extruder. The volatile content removing vacuum region of the volatile content removing vacuum unit 140 extends over a first region, which is under the control of the first extruder, and a second region, which is under the control of the second extruder. The pressure and temperature of the melted resin in the first region are controlled in accordance with the properties of the melted resin.

    摘要： A method of detecting impurities in a molten resin. The molten resin is massed through a passage having a window through which light can pass. Light is emitted from a light source through the window and the molten resin flowing through the passage. Sensors are used to sense a shadow produced when the light from the light source is interrupted by an impurity contained in the molten resin. Finally, the size of the impurity is measured from the width of the shadow and the intensity of light of the shadow. Also, judgment is made that if optical signals obtained by detecting the light that has passed through the molten resin indicate that there exist bright areas around a dark area, the dark area is distinguished as a shadow of an impurity. Further, in order to judge the shape of an impurity with high accuracy and record its image, a plurality of the devices used in the above method or the device used in the above method and a conventional camera may be used in combination.

    摘要： The pressure and temperature and in some cases the flow rate of fluids such as polymers are controlled by reducing the cross-sectional area of the conduit carrying the fluid to provide a flow channel communicating with the inner surface of the conduit whose cross-sectional area is less than that of the conduit. A valve housing is provided containing a chamber which communicates with the flow channel. The pressure and temperature and in some cases the flow rate of the fluid is controlled by adjusting the position of a valve member slideably disposed in the chamber. As the valve member slides within the chamber, it enlarges or reduces the cross-sectional area of the flow channel to change the flow resistance of the channel, thereby changing the pressure and temperature upstream of the channel and in some cases the flow rate through the channel.In applications where the material at the upstream end of the channel is wet and at a substantially greater pressure than the downstream end, it is desirable to also provide an elongated chamber whose inlet port communicates with the downstream end of the channel and which contains means for advancing and compacting material emanating from the downstream end of the channel. In cases where fragmentation of the material is produced by a rapid, and sometimes explosive, vaporization of the moisture associated therewith upon exposure of the material to the low pressure at the downstream end of the channel, the chamber contains the explosion, collects the resulting fragmented materials and compacts the fragments into a form more convenient to handle.
