Embodiment 1
[0013] Imported bleached sulfate "Silver Star" coniferous wood pulp is selected, with a beating concentration of 3.5% and a refining degree of 65 O SR, fiber wet weight 6g, adding alkyl ketene dimer synthetic glue to the pulp, the addition amount is 1% (on dry basis), and 2.5% (on dry basis) special starch for papermaking in the pulp for mixing. In this embodiment , the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.
[0014] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, first drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + The binder is synthesized at 5%, and the concentration is controlled at 5.5%, followed by secondary drying and calendering pretrea...
Embodiment 2
[0016] Imported bleached sulfate "Silver Star" coniferous wood pulp, beating concentration 4.0%, refining degree 70 O SR, fiber wet weight 5.5g, adding alkyl ketene dimer synthetic glue to the pulp, the addition amount is 1.3% (on dry basis), and 2.8% (on dry basis) special starch for papermaking in the pulp for mixing. In this embodiment Among them, the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.
[0017] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, first drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + The binder is synthesized at 5%, and the concentration is controlled at 6.0%, followed by secondary drying and calendering pretreatment. The temper...
Embodiment 3
[0019] Imported bleached kraft "Silver Star" coniferous wood pulp, beating concentration 5.0%, refining degree 75 O SR, the wet weight of fiber is 5.0g, the amount of alkyl ketene dimer synthetic glue added to the pulp is 1.6% (on a dry basis), and the amount of paper-making special starch added to the pulp is 3.2%, mixed in the pulp tank, in this implementation In an example, the paper-making special starch is: modified starch, of course, it can also be other paper-making special starches such as cationic starch, oxidized starch and amphoteric starch.
[0020] After double-sided molding and dehydration in the wire section, pressing and extrusion dehydration, drying in the front drying section, and entering the sizing machine to soak the surface of the paper sheet, the solution preparation material is surface sizing starch 45% + polyvinyl alcohol 50% + adhesive 5% of the agent is mixed and dissolved, and the concentration is controlled at 6.5%, followed by secondary drying and...
