METHOD OF MODIFIED WOOD MANUFACTURE Russian patent published in 2008 - IPC B27K5/06 B27M1/08 

FIELD: technological processes, construction.

SUBSTANCE: method of modified wood manufacture includes drying of natural wood, plasticization, three-sided sealing, fixation of form and stabilization of dimensions, at that drying of wood up to absolutely dry condition is carried in microwave field by exposure to pulse flux with specific capacity of 0.08-0.12 W/cm² and flux density of 1.0-1.2 W/cm² with duration of 30 s with intervals of 60 s with final treatment by means of convective method at the temperature of 115-120°C, plasticization is carried out by means of ultrasound effect with field intensity of 25-30 W/cm² for 80-100 s, and stabilization of dimensions is carried out by effect to wood frozen with liquid nitrogen with pulse magnet field with series from N=1500 to N=3000 of symmetrical triangular pulses with duration of 10 microsecond, amplitude B₀=0.3 T and repetition frequency of 10 ms for 30-60 seconds.

EFFECT: reduction of technological process duration.
