Design of a new microexplosion device for lumber.

A new type of microexplosion device is discussed in this paper, which can be used in microexplosion processing of lumber. The explosion of lumber is due to the pressure difference between the interior and exterior pressure of the device. A highspeed piston is designed to ensure that the interiro gas with a high pressure can be exhausted rapidly when the interior and exterior pressures maintain balance. The device improves the permeability of lumber and creates conditions for the improvement of lumber properties.
