| OBJECT: |
Disperse hard-to-wet gums at 1.5% to 2.0% concentrations - Carbopol, Methocel (Hydroxy Proply Methyl Cellulose) and Xanthan Gums |
|
PROBLEM: |
Prewet and predisperse gums without forming "fish eyes" by introducting gum powders in the down-mode. Then prove pumping capability to move and disperse viscous and thixotropic materials. |
|
RESULT: |
Excellent! AB mixer operated in down-mode to prewet and predisperse. Pumped entire volume of material. Product development manager issued report recommending AB production equipment. |
|
AB MIXER: |
CJ-4B lab mixer in 15 liter beaker. |
|
EQUIPMENT REPLACED: |
Gifford-Wood homo mixer which pumps in up direction only - thus allows gums to float on liquid surface causing "fish eyes". Also, material sticks to tank walls. |
