| titleOfInvention | The method that polishing prepares II crystal type nano fiber of lignocellulosic |
| abstract | The present invention relates to the methods that polishing of one kind prepares II crystal type nano fiber of lignocellulosic, comprising the following steps: (1) removes partial lignin；(2) strong base solution is handled；(3) residual lignin is removed；(4) a mechanical polishing.Advantage: 1) using a polishing, simple process, and energy consumption reduces, and yield improves, and operation difficulty is reduced with cost is produced；2) gained nanofiber is cellulose Ⅱ crystal type nano fiber, and diameter is evenly distributed, and thermodynamic property is stablized；3) wood powder mixed solution is handled with sodium chlorite and glacial acetic acid, remove the partial lignin in wood powder, remaining lignin can effectively inhibit the phenomenon that highly basic handles caused cellulose and reunites on a large scale in wood powder, subsequent mechanical treatment is carried out again, gained cellulose Ⅱ crystal type nano fiber yield is increased dramatically after primary grinding, up to 80-85%. |
