실험 절차

1280 g of de-ionized water was introduced into a 1 gallon vessel fitted with a Kady® Lab Mill and stirred at a motor speed of 15 Hz. 40 g of trisodium phosphate decahydrate and 2 g of citric acid were then added to the vessel. The temperature of the vessel was increased to 98° C. and 300 g of 3.5% aqueous solution of magnesium chloride was titrated into the vessel. 10 minutes after completion of the magnesium chloride addition, a sample was taken from the vessel and the pH of the sample was measured to be 7.7. The motor speed of the Kady® Mill was then increased to 45 Hz, and 450 g of Coarse Polymer Powder was introduced into the vessel. 30 minutes after introduction of the Coarse Polymer Powder, the vessel was rapidly cooled to 70° C. and the motor speed of the Kady® Mill was then reduced to 15 Hz while cooling continued until the temperature reached 25° C.
