    摘要: A blast media for stripping coatings or other contaminants from a solid surface comprises water soluble abrasive particles and a rinse aid which reduces the amount of water soluble residues of blast media remaining on the targeted surface and which enables any residues which remain to be readily removed by fresh water. The rinse aid can include magnesium oxide or a mixture thereof with one or more surfactants.

    摘要: A spray mixing nozzle and a method for reacting an acidic fluid and a basic fluid by using the spray mixing nozzle. The nozzle includes a central channel, at least one intermediate annular channel surrounding said central channel, an outer annular channel and a mixing chamber having a generally cylindrical upper section, a generally conically-shaped lower section and an axially aligned discharge orifice. The acidic fluid and the basic fluid are directed through the central channel and the intermediate annular channel into the upper section of the mixing chamber at relatively low velocities and a pressurized gas is simultaneously directed through the outer annular channel into the upper section of the mixing channel at a relatively high velocity. The high velocity gas acts to strip apart and at least partially atomize the acidic fluid stream and the basic fluid stream in the upper section of the mixing chamber. The gas and the partially atomized fluids are then subjected to a high degree of turbulence in the lower section of the mixing chamber and thereby substantially completely atomize and mix the fluids. The mixed and atomized fluids then begin to react and form a powdery or highly viscous paste product which is discharged from the discharge orifice.

    摘要: A blast media for stripping contaminants from a solid surface comprises abrasive particles and a surfactant in the form of a granular surfactant-clathrate compound formed of a surfactant and a water soluble compound having clathration capability such as urea. The surfactant reduces the amount of water soluble residues which remain on the targeted surface and enhances the removal of dirt, grease and oil from the targeted surface.
