Authors work on the development of the new high pressure injection mixing methods of construction for the purpose of volume-reducing it of sludge by the improvement of the ability for cutting.
In this report, I report particle size at the time of the water absorption of superabsorbency polymer materials, a jet test result during the mind that assumed the viscosity of the water solution a parameter and a jet velocity measurement result by PIV (Particle Image Velocimetry ).
