Analysis on the pulping process of paper and toilet paper-Jinling Paper Machinery

　　When the pulping process of the paper and toilet paper machine starts to add water, the flow measured by the flowmeter is calculated and determined according to the formula of / adding water = (pulp board weight x pulp board absolute dry weight) / concentration-pulp board weight 0 The amount of water added for pulping and pumping.

　　The main process parameters to be controlled in the pulping process are pulp concentration, time and pumping concentration. The concentration and time of pulping determine the degree of pulp disintegration. The pulping concentration of the toilet paper machine is the basic condition for the next step of refining.

　　When the pulp board descends into the activated pulping tank and the cumulative flow is equal to the calculated amount of pulping water, close the automatic water adding valve and start calculating the pulping time. This can be easily achieved with a timer or in the DCS program.

　　After the set time is reached, open the automatic valve to add water until the cumulative flow is equal to the calculated amount of water added for slurry pumping, while pumping is performed, so that a stable concentration of slurry can be obtained in the slurry tank.
