Characteristics of a ground aluminium diffuse plate at ultraviolate vacuum ultraviolate(UV VUV)and that of a BaSO 4 and a polytetrafluoroethylene (PTFE) diffuse plate at UV are described.
The inhibiting property for BaSO 4 scaling of phosphoric acid esters of rice bran extract (p RBE) alone and compounded with other scale inhibitors is studied.
