METHOD AND DEVICE FOR TREATING LIQUID IMPREGNATING PROCESS IN WOODEN MATERIAL AND POROUS INORGANIC MATERIAL AND ANTI DESTRUCTING METHOD FOR RADIAL PARENCHYMA WALL AND ASPIRATED PIT-PAIR OF WOODEN MATERIAL

摘要

PURPOSE: To provide a processing liquid impregnating method, by which processing liquid can be impregnated and infiltrated sufficiently into the interior of lumber without deforming the lumber. ;CONSTITUTION: The processing liquid impregnating method into wooden material and porous inorganic material consists of an initial stage pressurizing step, in which material to be processed is pressurized up to the predetermined pressure developing no deformation in the material to be processed and said pressure is held for a predetermined period of time, a preliminary pressurizing step, in which the material to be processed is pressurized stepwise up to the final pressurizing pressure after the elapse of the holding time in the initial stage pressurizing step and the pressures in the respective pressurizing steps are held for the predetermined periods of time, and a processing liquid pouring step, in which processing liquid is impregnated in the material to be processed under the predetermined processing liquid pouring pressure.;COPYRIGHT: (C)1994,JPO&Japio
