Title:
NANOCELLULOSE, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/157453
Kind Code:
A1
Abstract:
The present invention relates to the field of nanotechnologies, and provides a nanocellulose, a preparation method therefor, and an application thereof. The preparation method for the nanocellulose comprises: grinding forestry and agricultural residues to obtain a slurry; and hydrolyzing, performing enzymolysis, extracting, and concentrating the slurry to obtain the nanocellulose. The preparation method does not choose raw materials, and is low in consumption, high in efficiency, low in cost, and simple in process, and is suitable for industrial production. Moreover, in the process of extraction, the forestry and agricultural residues can be efficiently and thoroughly transformed for use without residues. The preparation method for the nanocellulose provides a new strategy for large-scale and industrialized nanocellulose production with controllable processing and stable dispersion. By means of application of the nanocellulose in a water purifying agent, good purifying and clarifying effects on sewage can be achieved by stirring, mixing, and filtering the nanocellulose and sewage.
