Set middle processing；
(2) baiting valve for opening steam blasting device makes material explosion in steam blasting device spray, obtains bamboo fibre；
(3) add water to adjust water content the bamboo fibre that step (2) obtains to spray uniformly to 50-60%, then on bamboo fibre
EM bacterium solutions are sprayed, heap fermentation is built, under the environment temperature of 10-30 DEG C of temperature, are fermented 3-5 days；
(4) bamboo fibre for obtaining step (3) is sent into the dry machine of dried disinfecting carbon, and the temperature of the dry machine heating of dried disinfecting carbon is
160-190 DEG C, 2-4 hours heating times, the carbonization of bamboo fibre thick bamboo tube, carbonizing degree is 5%-30%.
Preferably, the length of step (1) bamboo particle is less than 0.5cm, diameter is less than 0.2mm.
Preferably, the state modulator of step (1) steam blasting device is：The vapor temperature imported in steam blasting device
Degree control is at 140-160 DEG C, and in 0.36MPa-0.64MPa, processing time is 20-30 minutes for pressure control.
Preferably, the dosage of step (3) EM bacterium solutions is the 0.2-0.4% of bamboo fibre dry weight.
Preferably, the viable count of step (3) EM bacterium solutions is more than 0.9 hundred million/milliliter.
The beneficial effects of the invention are as follows：
1, using hydrogen peroxide dipping-steam blasting technique, the content of cellulose and bamboo fibre of bamboo fibre can be effectively increased
Gas porosity.
2, using the bamboo fibre after EM fermentation explosions, cellulose free hydroxyl group (- OH) quantity in bamboo fibre can be reduced, is enhanced
With the compatibility between plastics.
3, the present invention is carbonized to bamboo fibre by high temperature and pressure, has both enhanced the toughness of bamboo fibre, has also effectively prevent bamboo
Fibrous fracture keeps bamboo fibre non-discolouring, not rapid wear, and indeformable, the holding time is longer.
