Industry Challenge

    • Incorporation of Carbopol® and 40% Carbamide Peroxide into Glycerine.
    • Carbopol® is difficult to disperse into Glycerine because the low pH Glycerine solution results in instant hydration and viscosity increase.
    • 40% by weight Carbamide Peroxide is added to the Carbopol solution in a re-circulation to the mixing vessel.
    • Need to increase production without expanding the facility.

Quadro Liquids Solution

  • ZC1 inline disperser, skid mounted with a dual PD pump arrangement for performance with high viscosities and high solids addition rates and automated
  • Q-Vac vacuum powder addition system.

Controls to allow (3) pre-set operating points on inlet and discharge pumps:

  • Carbopol addition
  • Carbamide Peroxide addition
  • Auxiliary setting
  • Automated powder valve with level sensors in the hopper to control powder on/off addition.

ZC Powder Disperser Advantages

  • 75% reduction in overall batch time vs. conventional in-tank mixer processing.
  • Rapid incorporation & dispersion of solids without lumps or "fish-eyes".
  • Improved product consistency from batch to batch.
  • Increase in viscosity, the customer was able to reformulate and use less polymer.
  • The eliminated requirement to filter undispersed powders.
  • No over-processing common with conventional mixers preserving the rheological properties of shear-sensitive products.
  • Significantly reduced air entrainment.
  • Elimination of quality problems associated with cross batch contamination.
  • No excessive dusting from bag dumping into process vessels.
  • No solids build-up on process vessel walls.
  • Elimination of the requirement to expand the manufacturing area to increase production.
