Embodiment 1
[0028]The weight content of sugarcane pulp: wood pulp is 75:25, and five desanding processes are adopted. (1) A large-hole gauze is installed in front of the pulp washing box to remove coarse sand; (2) Desanding is installed before refining (3) Set a medium-hole gauze after refining; (4) Set a grit settling plate before entering the pulp box; (5) Set a small-hole gauze at the lower part of the headbox of the paper machine net, to remove fine sand; and then use a 3.66-meter fourdrinier large-diameter double-cylinder papermaking temperature is easy to control, which can improve product quality. Use the HTDQ-N type pulp concentration automatic measuring and controlling instrument to measure the concentration of paper before and after different equipment. After the measurement and control, the pulp concentration is adjusted in time to ensure that the flow rate and sizing of each part are uniform, and then the flexible fiber-separating broom is used to make the pulp to a certain ex...

[0031] 1. The weight content of sugarcane pulp: wood pulp is 85:15, and five sand removal methods are used. (1) A large-hole gauze is installed in front of the pulp washing box to remove coarse sand; (2) Install before refining Sand remover to remove medium sand; (3) set a medium-hole gauze after refining; (4) set a grit settling plate before entering the pulp box; (5) set a small hole in the lower part of the headbox of the paper machine Hole gauze to remove fine sand; and then use a 3.66-meter fourdrinier large-diameter double-cylinder papermaking temperature is easy to control, which can improve product quality. Use the HTDQ-N type pulp concentration automatic measuring and controlling instrument to measure the concentration of paper before and after different equipment. After the measurement and control, adjust the pulp concentration in time to ensure that the flow rate and sizing of each part are uniform, and then use a flexible fiber-splitting broom to make the fibers ha...
