EXPLOSION PULPING |
摘要 |
In an explosion pulping process an inert gas is injected into the steamed pulp prior to explosion, to raise the pressure; the resulting exploded pulp displays improved mechanical properties and requires less refining time and refining energy. By employing lime in a presoaking treatment and carbon dioxide in the inert gas, deposits of calcium carbonate are formed on the fibres, providing improved brightness characteristics.
