titleOfInvention | Pitch control method using microorganisms to prevent pulp brightness reduction |
abstract | A pitch control method for preventing a decrease in whiteness of a mechanical pulp, characterized by adding a microorganism and a specific reducing bleach to a mechanical pulp slurry to cause a biological reaction. provide. SOLUTION: By adding a microorganism and thiourea oxide or hydrosulfite or a mixture thereof to a mechanical pulp slurry, particularly, adding a thiourea oxide or hydrosulfite or a mixture thereof to a mixed reaction solution of the mechanical pulp slurry and the microorganism. Pitch decomposition is performed by adding the mixture. |
