Embodiment 1
[0029] A. Cotton pulp preparation
[0030] Disperse the cotton pulp board with a dispersing device such as a bulk bag machine, a meal feeder, and a leaf splitter, etc., use cutting equipment and crushing equipment such as a pulper, and a pulverizer to crush the pulp board into flocs, and use a conveying device (Blower, cyclone separator, screw conveyor) Send the cotton pulp board into the steamer, and add NaOH solution while putting the cotton pulp board into the steamer. This stock preparation method is called dry stock preparation in the art. The cotton pulp side of the present embodiment adopts this material preparation method to prepare materials.
