| 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. |
