Abstract
The invention discloses a straw papermaking process which comprises the following steps: (1) softening straws; (2) pouring the softened straws into a twin-screw twisting machine for extrusion devillicate; (3) pouring the material into a reaction chamber of 90 DEG C, and performing hydrogen peroxide bleaching reaction for 90 to 100 minutes; (4) pouring the material into another twin-screw twistingmachine for second extrusion devillicate; (5) pouring the extruded material into a pulping machine for pulping to obtain coarse pulp; (6) pouring the coarse pulp into a fiber disintegrator for disintegrating 5 minutes; (6) pulping the disintegrated coarse pulp with the pulping machine to obtain fine pulp; (7) removing the non-pulped residue from the fine pulp by using a residue remover to obtain clean pulp; (8) removing water from the clean pulp by using a centrifugal dewatering machine to obtain concentrated pulp; (9) adjusting the pH value of the concentrated pulp to 7 with a neutralizer ina pulp adjustment tank to obtain adjusted pulp; (10) making the adjusted pulp into pulp boards or paper products by using a forming machine. The straw pulp concentration is high, and the product quality is good.
