RemarksUnneutralizedNeutralized


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
 
Viscosity stability:Store millbase in 100ml wild-mouth bottle at 40ºC for 24 hours, measure viscosity change,  ±50% change is regarded qualified.

Example1(★:Excellent  ☆:Good )

Experimental pigment: Alumina powder, powder content 60%

Pigment content:                  60

Dispersant dosage(as supplied):    1.8

Defoamer(Toynol®):               0.1-0.3

Wetting agent(Toynol®):            0-0.3(as appropriate)

Water:                           add to 100%

Remarks:Put Alumina and Toynol DS-192 series dispersing agents together through grinding, pulping, dusting and drying to get modified alumina powder. The modified powder can provide "instant" dispersion effect while soluble in water.

Example2(★:Excellent  ☆:Good )

Experimental pigment: Carbon black C-168 , powder content  20%

Organic pigment content:          20

Dispersant dosage(as supplied):    30

Operation proposals      
 
1. Suggested dosage of Alumina powder(Based on pigment, Toynol® dispersants calculate solid content SOP):0.5-1%.
 
2. Suggested dosage of neutral color carbon black(Based on pigment, Toynol® dispersants calculate solid content SOP):50-100%.
 
3. Suggested dosage of conductive carbon black(BP-2000)(Based on pigment, Toynol® dispersants calculate solid content SOP):50-60%.
 
3. Toynol® wetting agents can accelerate original powder wetting.
 
4. Adding Toynol® defoamers can quickly eliminate grinding foam.
 
5. To obtain optimal performance, Toynol® additives
 
Storage

As liquid material, this product should be sealed and placed in a dry, cool, well-ventilated place at room temperature
