A method of impregnation of wood includes evacuation at stages of preliminary impregnation and post-impregnation, and also at the stage of impregnation, which is achieved under action on it of excess pressure. Impregnation is conducted by steps that grow to 30 atm., with stages of 5 atm. each, with holding at each stage during 20-30 minutes, by pulse pressure with amplitude of pulsation of 2 atm. and with frequency up to 100 oscillations per minute, which is created by dosing pump. |
