METHOD OF IMPREGNATION OF TIMBER Russian patent published in 2014 - IPC B27K3/08 

FIELD: woodworking industry.

SUBSTANCE: for impregnation of timber the material is charged into the chamber, the chamber is sealed and vacuum is created in it. Then, the impregnating solution is supplied and overpressure is created in the chamber to a predetermined value. At that the volume of gas evacuated while vacuuming in the chamber is measured. The impregnation process is stopped when the volume of the injected impregnating solution is equal to the volume of evacuated gas. The gas volume evacuated while vacuuming in the chamber and the volume of the impregnating solution injected into the chamber are measured at atmospheric pressure.

EFFECT: improving quality of impregnation due to accurate determining the moment of termination of impregnation regardless of the linear dimensions, humidity, timber species and properties of the impregnating solution.
