OBJECT: | Disperse black pigments or blue pigments into castor oil and sulfonamide plasticizer. |
PROBLEM: | Viscous ink is difficult to pump with radial flow mixers or high speed dispersers. |
RESULTS: | High recirculation rate through high shear zone disperse pigment completely. |
AB MIXER: | Model C-3-2 20 HP, 3600 RPM – 2 mixers dedicated to each color (black/blue). |
BENEFIT: EQUIPMENT REPLACED | Mixing time cut in half/larger batches possible because baffle plate can manage flow allowing higher fill level. HSD |
