Embodiment 1
[0047] A fiber raw material for papermaking is obtained by the following process route:
[0048] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the skin, pulp and leaves, and then dried in the field until the moisture content was 15% and bundled.
[0049] see figure 1 and figure 2 , the agricultural harvester that the present embodiment adopts comprises chassis 4, power unit, electric device, hydraulic system, driver's cab 5, harvests the stalk harvesting table 1 of corn stalk, tears corn stalk, pulverizes, and the skin, pulp The corn stalk husk and leaf separation device 3 for separating the corn stalks and leaves, transporting the harvested corn stalks to the corn stalk husk and leaf separation device 3 for tearing and crushing the corn stalks and separating the skin, pulp and leaves 2. Fasteners are used to directly connect each structure or each struc...
Embodiment 2
[0062] A fiber raw material for papermaking is obtained by the following process route:
[0063] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the skin, pulp and leaves, and then air-dried in the field until the moisture content was 45% and bundled.
[0064] On the basis of Embodiment 1, the agricultural harvester used in this embodiment further adds a straw husk dispersion device 6 and an anti-blocking device 7, see image 3 , its operation process is the same as embodiment 1.
[0065] The straw husk dispersing device 6 is fixedly connected to the outlet of the axial flow drum 11 . The strip-shaped straw husks separated by the corn stalk husk and leaf separation device 3 will be arranged irregularly when they are discharged to the ground, and may be crushed by the rear wheels of the harvester. Well, there may be piles and it is not easy to dry. Therefor...
Embodiment 3
[0070] A fiber straw raw material for papermaking is obtained by the following process route:
[0071] The corn stalks harvested in the mature period of corn are passed through the agricultural harvester (such as figure 1 and figure 2 Shown) harvested, separated from the bark and leaves, and then air-dried in the field until the moisture content was 30% and bundled.
[0072] Described agricultural harvester is with embodiment 1.
[0073] In the obtained fiber raw material for papermaking, relative to the dry raw material, the mass percentage of water-soluble sugar in the corn stalk husk is 12.15%, the mass percentage of cellulose is 68.32%, and the mass percentage of lignin is The percentage content is 13.85%; the crystallinity of the corn stalk husk is 47.96%. The corn stalk husks include strip-shaped straw husks and straw husks, the strip-shaped straw husks have pulp remaining, and the residual amount of the pulp on the strip-shaped straw husks is 0.5%.
[0074] In this...
