ABSTRACT:
A pressure saturator for impregnating porous substrate materials with solids in solution, in which a reservoir contains the saturant solution and has a base member with a portion forming a depression therein. A mandrel is disposed within the depression in spaced relation to the surface of the depression. Preferably, the distance between the surface of the depression and the mandrel is three times the thickness of the substrate material. Heating elements are disposed in the base and heat the portion of the base member forming the depression, thereby heating the solution between the mandrel and the surface of the depression. The substrate is fed into the saturator from a supply roll and is passed through the space between the depression and the mandrel. The heated solution causes solids from the solution to replace the air in the interstices of the substrate in a near 100 percent weight-to-weight saturation. The area of the reservoir above the depression and mandrel may be cooled to provide a more effective exchange within the substrate.
