Embodiment 1
[0028] A high-yield pulp release paper production process, comprising the steps of:
[0029] S1. Extrude the selected coniferous wood chips according to the compression ratio of 4:1, and immerse the extruded coniferous wood chips in the first treatment liquid at 55°C for initial treatment, and perform high-pressure blasting at a pressure of 1.2 MPa Treat for 3 to 5 minutes; then immerse the softwood chips in the second treatment solution at 70 °C for secondary treatment, and perform high-pressure blasting treatment at a pressure of 1.0 MPa for 2 minutes;
[0030] S2. Refining the coniferous wood chips treated in step S1, and washing and eliminating latent treatment of the pulp obtained after grinding in turn; dispersion;
[0031] S3. Adjust the pH of the decomposed pulp to 2.8, then continuously inject ozone into the pulp, and treat it at 35°C for 100s; after the treatment, add an appropriate amount of cellulase to the obtained pulp, and adjust its pH Adjust to 3.8, treat at...
Embodiment 2
[0044] A high-yield pulp release paper production process, comprising the steps of:
[0045] S1. Extrude the selected coniferous wood chips according to the compression ratio of 4:1, and immerse the extruded coniferous wood chips in the first treatment liquid at 70°C for initial treatment, and perform high-pressure blasting at a pressure of 1.5 MPa Treat for 4 minutes; then submerge the softwood chips in the second treatment solution at 80°C for secondary treatment, and perform high-pressure blasting treatment at a pressure of 1.2MPa for 2 minutes;
[0046] S2. Refining the coniferous wood chips treated in step S1, and washing and eliminating latent treatment of the pulp obtained after grinding in turn; dispersion;
[0047] S3. Adjust the pH of the decomposed pulp to 3.0, then continue to pass ozone into the pulp, and treat it at 40°C for 120s; Adjust to 4.5, treat at 50°C for 45 minutes; then add fillers to the pulp to prepare mixed pulp; then make the mixed pulp into paper...
Embodiment 3
[0060] A high-yield pulp release paper production process, comprising the steps of:
[0061] S1. Extrude the selected coniferous wood chips according to the compression ratio of 4:1, and immerse the extruded coniferous wood chips in the first treatment liquid at 90°C for initial treatment, and perform high-pressure blasting at a pressure of 1.7 MPa Treat for 5 minutes; then submerge the softwood chips in the second treatment solution at 85°C for secondary treatment, and perform high-pressure blasting treatment at a pressure of 1.3MPa for 3 minutes;
[0062] S2. Refining the coniferous wood chips treated in step S1, and washing and eliminating latent treatment of the pulp obtained after grinding in turn; dispersion;
