Grinding operation

Dispersing sand mill, Glass bead(0.8-1.2mm), Filling rate 70%
3000rmp/min  60min

Performance evaluation
  • Centrifugal stability: take 20ml millbase into centrifuge tube, centrifuge 10 min under condition of 3000r/min, then take out to observe the layering of millbase. Pour out liquid and calculate amount and percentage of precipitate.
  • Viscosity evaluation:Use Brookfield rotational viscometer.
  • Fineness measure:Scraper fineness meter
  • iscosity stability:Store millbase in 100ml wild-mouth bottle at 40ºC for 24 hours, measure viscosity change,  ±50% change is regarded qualified.

(When actual operation:First add dispersant into water, then add powder, 4000rmp/min 10min. After powder completely wetting, put into grinding glass beads to start timing grind.)

Recommended Applications
  • Water-based inks
  • Architectural coating
  • Wood and furniture coatings
  • Automotive coatings
  • Can coatings
  • Anticorrosive paint
  • Leather coatings
Operation proposals       
  1. Suggested dosage of organic pigment(Based on pigment, Toynol® dispersants calculate solid content SOP):10-50%.
  2. Suggested dosage of inorganic pigment(titanium dioxide)(Based on pigment, Toynol® dispersants calculate solid content SOP):3-7%;
  3. Do not add wetting agents separately.
  4. Toynol® wetting agents can accelerate original powder wetting.
  5. Adding Toynol® defoamers can quickly eliminate grinding foam.
  6. To obtain optimal performance, Toynol® additives must be added in water before resin and pigment.
  7. Advise gradient test to get optimal dosage.
