| 摘要 |
The invention relates to a method for the quick and careful heating of wood or other materials which are sensitive to dehydration and heat damage. The heating is effected by placing the material in a chamber from which the air is completely evacuated prior to the heating phase. The chamber is then filled with saturated water vapours at a temperature which does not significantly exceed the temperature of the material which is required to be heated. The heating takes place by the saturated water vapours penetrating the spaces between the individual material parts. Here, the vapours condense on the surface of the material, whereby the material is heated. Among other things, the method can be used with advantage for the fixation of a number of impregnation agents in wood and for the drying of wood. There is also revealed an apparatus for use in the execution of the invention. (Fig. 1)
