Point of the Proposed Technology

・ By pressurizing raw materials and making them colliding each other or against ball at high-pressure inside chamber of the unit, raw materials can be refined.


・Improve dispersion function
・Simplify disjoining and cleaning

Conventional Technology

Example of application to carbon nanotube

・Dispersion difficulty
Depending on the manufacturing method, the diameter and the shape、characteristics of carbon nanotube are different. Therefore, it was
difficult to loosen condensation and let it disperse in the aqueous solution.  

・Use organic solvents
In order to make carbon nanotube disperse, organic solvents is used but it is not good regarding operation environment.

New Technology

Example of application to carbon nanotube

・Enables dispersion
Using wet type jet mill processing enables constant dispersion.

・Saves the use of organic solvent
As the wet type jet mill processing loosens condensation of carbon nanotube by high-pressure jetting, it decreases the use of organic solvent.

・Disjoining and cleaning
The desktop wet type jet mill unit is small and 100V power supply, so it can easily use and test, and particulary suits at the experiment stage.
