| OBJECT: |
Disperse 22% carbon black into Tri-Ethylene Glycol.
|
|
PROBLEM:
|
Dispersion must be 100% minus 100 microns since it will be inserted into a hollow fiber with 200 microns inside diameter. These fibers are used to make suits resistant to chemical warfare agents. |
|
RESULT:
|
Excellent dispersion with 1-10 micron distribution. |
|
AB MIXER:
|
Model CJ-4B in 1 gallon.
|
|
EQUIPMENT REPLACED:
|
Performed dispersion using down-mode - - competitive Tekmar unit required 2-3 times as long on smaller batches. |
