Abstract

The impregnating process consists of putting the solid in an autoclave; introducing a gas up to a preset pressure; setting the pressure equalization in the solid to a preset protective pressure; introducing a liquid impregnator; raising the pressure in the autoclave to above the protective pressure to facilitate impregnation; and reducing the pressure in the autoclave to ambient pressure.
