| description | The invention provides a method for preparing natural bamboo fibers through high-temperature and high-pressure blasting, which comprises the following steps: processing a moso bamboo material of 3-5 years old into bamboo chips with the length of 5-10cm and the width of 1.5-3.0 cm, and putting the bamboo chips into a blasting pressure tank directly or after soaking pretreatment; and the temperature in the tank body is increased to 120-250 DEG C and the pressure is increased to 1.2-1.8 MPa within 10-20 min through a heating device. And after the preset temperature and pressure are reached, the pressure is maintained for 5-10 minutes, and then the bamboo chips are instantaneously blasted and impacted into the natural bamboo fibers by opening the sealing cover and suddenly-reduced pressure. The method does not need to add chemical reagents, is simple in process, environment-friendly and efficient, can maintain the integrity and mechanical properties of the natural bamboo fibers, and is suitable for large-scale pr |
