Manufacturing method of mechanical pulp from cornstalk

摘要

The present invention is added to increase the annual release cornstalks seconds, before adding the increased release, during, after mechanical by refining (refining; refining) to completely remove the cornstalk fibers as hayeoseo relates to a process for the manufacture of mechanical pulp from cornstalk cellulose pulp to obtain a manufacturing method of mechanical pulp from cornstalk cellulose in accordance with the present invention, the cornstalks as a raw material In producing a pulp by: (1) 100 parts by weight of pulverized caustic in the crushed cornstalks soda, sodium carbonate, was added 0.5 to 5 parts by weight of release increased is selected from sodium oxide or made of a mixture of two or more of these groups, impregnated After separating the solids by cooking for 1 year chajeung step; (2) The first step is to chajeung in more parts of the cooking added increased release of 5 to 10 parts by weight to the obtained mixture, and then impregnated, by steps of 2 chajeung cooking to remove the solids; comprising the jidoe, the second chajeung immediately prior to step, said second chajeung to separate a solid component to be subjected to the steps to during or after the cooking in the second step to chajeung mechanically refining step of refining; yirueojim characterized by including
