Method of preparing cellulose nano-fibres from stalks of annual plants

摘要: The method of manufacturing cellulose nano-fibres from stalks annual crops consist in that pieces the plants are sequence subjected to action steam, mechanical defibrillation, digestion a digesting liquor, oxygen delignification aqueous medium containing NaOH and MgSO 4 , bleaching with sodium chlorite done at least twice, alkaline extraction an solution, enzymatic treatment prepared pulp by cellulase 10-1000 J/g activity endo-l,4-beta- glucanase J/g. After washing enzyme deactivation, suspension is put homogenization centrifugation obtain supernatant which contains nano-fibers.
