Study on the Preparation of Coal Water Slurry and Its
bubbles when stirred by more foaming agents on the surface. If the non ionic additives are used for pulping they are also good foaming agents. There are too many bubbles in coal water slurry which will greatly affect its fluidity. At this point the defoaming agent needs to be added to eliminate its influence.
