System for controlling the color of compounded polymer(s) using in-process color measurements. |
摘要 |
A system for controlling the color of compounded polymer(s) comprises: a compounder (140) for mixing the constituents of the compounded polymer(s) to produce a substantially homogeneous mixture; a sensor (110) for measuring the color of the substantially homogeneous mixture at predetermined intervals; a colorant additive feeder (130), responsive to a controller (120), for providing the colorant additive(s) to the mixture at substantially predetermined colorant additive addition rates; and a controller, responsive to the sensor, for controlling the colorant additive addition rate(s) of the feeder. <IMAGE> |
