Grinding operationDispersing sand mill, Glass bead(0.8-1.2mm), Filling rate 70%
3000rmp/min 60minPerformance evaluationCentrifugal 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 meteriscosity stability:Store millbase in 100ml wild-mouth bottleTimer & Counter at 40ºC for 24 hours, measure viscosity change, ±50% change is regarded qualified.
