Heap liquid storage after pH value is uniformly mixed in the ratio that liquor ratio is 1:4-1:10, is placed at 15-30 DEG C and is stored up 4-24 days；
(2) after treatment air-dries after originally water washing 0-3 times up to porous fiber material.
The marrow rate of removing of the Bagasse Material is 30%-45%.
The heap liquid storage is tap water or industrial water.
The diluted acid is sulfuric acid, phosphoric acid or the acetic acid etc. of volumetric concentration 0.1mol/L-1.0mol/L, and diluted alkaline is volumetric concentration
For the sodium hydroxide, potassium hydroxide or calcium hydroxide etc. of 0.1mol/L-1.0mol/L.
Controlling heap by way of the tap water or industrial water of 15-45 DEG C of gravity-flow ventilation and spray during the stockpiling
The temperature of storage material is at 15-30 DEG C.
The liquor ratio: the ratio between over dry raw material weight (kg) and total liquid measure volume (L).
The beneficial effects of the present invention are:
(1) bagasse wet process stockpiling of the present invention processing is a kind of energy-saving and environment-friendly processing mode, and heap liquid storage be tap water or
Industrial water, required condition is more mild in treatment process, easy to operate, energy conservation and environmental protection；
(2) porous fibrous material average pore size made from is 6.2-9.4nm, specific surface area 0.98-1.45m2/ g, 2-10nm's
It is 5.48nm, specific surface area 0.8995m that hole representative fraction, which is greater than the untreated bagasse average pore size of 58%(,2/ g, 2-10nm's
46.20%) hole ratio is；Under room temperature, more untreated bagasse Alkali absorption amount in 20min, which improves, is up to the untreated sugarcane of 80%(
Alkali absorption amount is up to 8.03g/100g over dry bagasse in slag 20min)；
(3) wet process stockpiling processing bagasse can be effectively by raw material aperture structure and specific surface area control in certain model in the present invention
In enclosing, sugarcane fiber material is improved in height compacting density board, porous fibre carbonization and prepares high-specific surface area carbon material, as suction
The application potential of enclosure material etc..
