Abstract

A method for production of a wooden plastic material, preferably tile, from wooden particles without a binder provides for forming a wooden particles pack between a die (1) and a punch (2), hermetization of the volume (4) including the pack with its preliminary moistening, heating up to a temperature not lower than 150 °C, pressing up to stabilization of the pressure of the vapour-gas mixture filling the hermetized volume and removing the vapour-gas mixture from the whole surface of the wooden plastic material through channels (3) before taking off the forming pressure.

The evaporation of water, which is always present in wood, makes it difficult to reach temperatures above 100 Celsius. By supplying a gas-vapor mixture from a volume of a consumed material, it is directed to a substantial extent that it is safe to heat an external heater, Generally speaking, the pressure of the vapor-gas mixture, which adheres to the material, may result in damage to it and even in the event of disruption and depressurization of the heat immediately
