Product advantages: to solve the wood chip raw materials, destroy the outer layer of the fiber cell wall, reduce the amount of cooking liquid, reduce the amount of alkali used for chemical pulp cooking more than 5%; for mechanical pulping can reduce the refining power consumption by more than 10%. Chemical pulping can increase the contact surface of the cooking liquid with lignin and accelerate the removal of lignin. After the amount of alkali is reduced, the damage to hemicellulose and cellulose is reduced, and the quality of the pulp is improved. Reduce production costs and increase production efficiency.
