Melting pulp manufacturing method and melting pulp

摘要

Melting pulp manufacturing method comprises the steps of: S1) steaming and cooking wood chips to obtain brown stock; S2) subjecting the brown stock to oxygen delignified to obtain an oxygen-talignified stock; S3) performing enzymatic hydrolysis by mixing the oxygen-taligninated stock and hemicellulose to obtain an enzyme-hydrolyzed stock; And S4) bleaching the enzyme-hydrolyzed stock and performing paper making on the enzyme-hydrolyzed stock to obtain pulp for dissolution. Hemicellulase is added after oxygen delignification to remove hemicellulose from the stock, whereby lignin can also be easily removed, thereby promoting bleaching of the dissolving pulp, reducing the amount of bleach used, and reacting. Can cause mildly. In addition, cellulose is retained to a maximum extent during the removal of hemicellulose and lignin, improving the pulp fiber content and performance of the dissolving pulp, and reducing contamination caused by waste water.
