Title:
METHOD FOR CONCENTRATING RECYCLED CARBON SHORT-FIBER SLURRY
Document Type and Number:
Japanese Patent JP2020158941
Kind Code:
A
Abstract:
To provide a method of reducing a volume for concentrating and storing or transporting a low-concentration de-fiberized recycled carbon short-fiber slurry, and a method of easily removing a concentrated recycled carbon short-fiber, by using a high-speed rotary shear type disperser to produce a uniform non-woven fabric from recycled carbon short-fibers by a wet papermaking method.SOLUTION: There is provided a method for concentrating a recycled carbon short-fiber slurry, in which a recycled carbon short-fiber slurry that is de-fiberized and dispersed using a high-speed rotary shear type disperser is concentrated while being filled inside a conical trapezoidal filter cloth tied to an outlet of a liquid feed pump.SELECTED DRAWING: None
