Abstract
Disclosed is a method for impregnation of matters in wood utilizing sound vibration energy. The impregnation method is to impregnate specific functional matters or specific color paints into a semi-finished wood processed in the fiber direction or in the rectangular fiber direction. Impregnation fluid is coated on the surface of the semi-finished wood relatively thin, and the vibration generating surface of a sound vibration generator is located inside the impregnation fluid. At this time, the sound vibration generator is separated from the surface of the semi-finished wood at a predetermined interval and applies ultrasonic vibration. The impregnation method is economical as using the low-volume sound vibration generator, uses the minimized amount of the impregnation fluid, performs the impregnation work to a deep portion of the semi-finished wood, and maximizes impregnation efficiency as applying the sound vibration energy at the optimum angle when the surface of the semi-finished wood is in the fiber direction or the rectangular fiber direction.
