Process step in dispersion machine
1, Put the resin into water with stirring
2, Stirring the resin and ensure the resin be totally in water (10 to 20 minute)
3, then, add 80% ammonia water, half an hours later, add the remaining 20% ammonia water, this helps to reduce the volatilization of ammonia water, fully promote the soluble.
4, High speed stirring(1200-1500r/min)until the resin be dissolved fully. (about 3.5-4.5 hours)
5, PH remains in 8.5-9.5 , you can adjust the PH value by add ammonia water.
