Description
Technical field
The present invention relates to technical field of chemical engineering, specially a kind of preparation method of bagasse microballoon.
Background technique
Bagasse is the main waste (accounting for 24%~27%) of sugar industry.Southern sugarcane district sugarcane total output more than 7,000 ten thousand
Ton, the bagasse yield generated every year is about more than 2,000 ten thousand tons.In terms of the comprehensive utilization of bagasse, long sugarcane slag part is common
In papermaking, and staple fiber carries out burning processing into boiler frequently with dispensing, fails sufficiently to comprehensively utilize.Therefore, how to sweet
Bagasse is efficiently used, and the added value of bagasse is promoted, and is always the hot issue of sugar industry urgent need to resolve.
Cellulose, cellulose composite modification material and derivative product, have been widely used for plastics, weaving, papermaking, food
The fields such as product, daily-use chemical industry, medicine, building, petrochemistry and biochemistry.Modified cellulose has preferable absorption property,
Therefore it can be developed into adsorbent.The stability of modified cellulose adsorbent is high, adsorptive selectivity is special, and price is well below absorption
Resin.For example, after introducing function base, mutual spacing is about since cellulose and its derivates have open backbone
50, so the carrier as chromatographic material and bioactivity has been widely applied.However due to native cellulose physical form
It is powder or threadiness, pore structure is poor, and liquid flowing resistance is big, specific surface adsorption area is small, filling is difficult, greatly limits
Its application.As being cellulose microsphere by remodeling exploitation, the matrix for having loose hydrophilic network structure is formed, it is increased
Specific surface area improves the transparent performance and liquid fluidity of cellulose, by the absorption property that can significantly promote cellulose and answers
Use performance.
Since the cellulose and hemicellulose level of bagasse are higher, abundance, inexpensive, there is biodegrade well
