摘要
A simple optical on-line residence rime distribution (RTD) measurement technique has been developed. Changes in extrudate light transmittance are monitored by a photomultiplier. A He-Ne laser is the light source with carbon black as the tracer. The RTD of a ZSK-30 twin-screw extruder was measured using this technique. The effects of feed rate, screw speed, and melt viscosity on the RTD were studied. Also, the effect of the presence of an in-line rheometer an RTD was examined. The advantages and disadvantages of the technique are discussed.
