ABSTRACT:
A method and an apparatus is provided for accelerated processing of cement-bonded particleboard or fiberboard under pressure through the injection of a diluted carbon dioxide gas. The method and apparatus yield controlled, thorough and efficient acceleration of the curing process, reduce the cost and raw material consumption in the process, broaden the raw materials basis for the production of cement-bonded particleboard and fiberboard, and yield end products with improved mechanical, physical and durability characteristics. Streamlined processing plants with improved productivity and efficiency can be based around this invention for the production of cement-bonded particleboards and fiberboards with improved performance characteristics.
