Title:
NANOFIBER CONTINUOUS CRUSHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/056551
Kind Code:
A1
Abstract:
Disclosed is a nanofiber continuous crushing system, comprising a homogenizing chamber (100), a centrifugal chamber (300), an extrusion chamber (500) and a condensation channel (800), wherein the homogenizing chamber (100), the centrifugal chamber (300) and the extrusion chamber (500) are in communication in sequence, an outer wall of the extrusion chamber (500) is provided with an injection needle (600) in communication with the extrusion chamber (500), the injection needle (600) is provided in the condensation channel (800), the condensation channel (800) is in communication with a gas supply device supplying freezing gas, an inner wall of the condensation channel (800) outside the injection needle (600) is provided with an electrode plate (810), and the injection needle (600) and the electrode plate (810) are respectively in communication with two poles of a static electricity generator. The crushing system uses a drawing process of electrostatic spinning to perform drawing on a cellulose solution, and performs freezing, bending and crushing on the drawn fibers by means of the condensation channel to form nanocellulose fibres. Since only very slight force is required to pulverize the drawn fibers in a frozen state to prepare nanocellulose fibres, the system has the capability of efficient and rapid production of nanocellulose fibres.
