Method and apparatus for a spectroscopic examination of plasticized extrudates |
摘要 |
<p>Method for spectroscopic analysis of plasticized extrudate in an extruder comprises irradiating it with electromagnetic radiation and spectroscopic analysis of the reflected radiation. The extrudate in the area of the extruder screw is irradiated radially and the radiation within it is reflected from the screw after moving a distance 'd'. The reflected radiation is then analyzed. Method for spectroscopic analysis of plasticized extrudate in an extruder (1) comprises irradiating it with electromagnetic radiation (12) and spectroscopic analysis of the reflected radiation (14). The extrudate in the area of the extruder screw (2) is irradiated radially and the radiation within it (12a) is reflected from the screw after moving a distance 'd'. The reflected radiation is analyzed at repeated positions separated by the same distance. An Independent claim is included for a device for carrying out the above method.</p> |
