Title Proper : IN-LINE COLOR MONITORING OF POLYMERS DURING EXTRUSION USING A CHARGE COUPLED DEVICE SPECTROMETERPOMPES PAR TRANSITIONS MULTIPLES
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : ,4n inexpensive. fiber-optic equipped. charge coupled device spectrometer wasused to monitor both color and residence time distributions in polyethylene melts duringextrusion. A procedure involving quality control charts and spectral correction factorswas developed and then used to examine the effect of screw RPM on color change-oversin a single screw extruder. A method of deriving residence time distributions from the in-line acquired retlectance spectra was derived. Dimensionless time (timeimean residencetime) was shown to superimpose the residence time distribution data at the two screwspeeds investigated. in accord with theory. It also superimposed L*a*b* time dependentdata at the different screw speeds. Thus. the shape of these curves was unaffected.
