Embodiment 1
[0036] Camellia oleifera husks are washed and dried in the sun, mechanically treated to a width of 1.0 cm, and a length of 0.5-2.0 cm; soaked in distilled water at a solid-to-liquid ratio of 1:2 (g:ml), at room temperature and pressure for 24 hours, then subjected to steam explosion, blasting The pressure is 2.0 MPa, and the pressure is stabilized for 5 minutes; the slurry obtained by blasting is sieved by a flat screen with a sieve plate size of 8 mesh to obtain a fine pulp, and the fine pulp is mixed with bleached softwood pulp (the degree of beating is 40 o SR) to obtain wet paper, the basis weight of the paper is 80 g / m 2 , when the amount of camellia oleifera husk slurry was 10.0wt%, the obtained wet paper was pressed under a pressure of 0.4 MPa, dried at 95 ℃ to obtain camellia oleifera husk wrapping paper, and its physical properties were tested after constant temperature and humidity. The air permeability of the paper is 1.35 um / (pa*s), the tensile strength is 53.24 Nm...
