Device and method for reducing color difference on the surface of chemical fiber paper tube

Abstract

The invention discloses a method for reducing the color difference on the surface of a chemical fiber paper tube, which relates to the field of chemical fiber paper tube manufacturing. The method comprises adopting an automated dye adding system, using a pH value and a temperature sensor for real-time monitoring, combining a temperature compensation algorithm and a temperature-dye reaction rate model, and dynamically adjusting the dye concentration and reaction conditions; optimizing the dye ratio, acidification treatment, environmentally friendly coating, and improving the treatment process of the surface of the chemical fiber paper tube, using a high-precision color difference detection device, detecting the color difference in real time, connecting the colorimeter data to the production line control system, automatically adjusting the dye concentration and pH value parameters, realizing dynamic correction, and ensuring color consistency between batches.
