Embodiment 1
[0015] Use a pulverizer to crush the dry ramie into short fibers of 30-80 mesh, put the short fibers into a container with a sealing ring to balance the water, and measure the moisture regain of the short fibers; weigh the quality of the short fibers, and calculate the fiber according to the moisture regain. Dry weight; add distilled water to the short fiber, and soak the cellulose in distilled water to fully wet the cellulose; wherein, add distilled water to the short fiber so that the mass percentage concentration of the cellulose solid in the distilled water is 3%, and the soaking time in distilled water is 20h.
[0016] Stir short fibers with a beater to make cellulose pulp; put the prepared pulp into an ultrafine refiner, the rotor and stator discs of the ultrafine refiner have gaps and grooves on the surface, set the rotor and stator The distance between the discs allows the slurry to pass through the gap between the grinding stones of the ultra-fine refiner; adjust the r...
