METHOD FOR MANUFACTURING PARTICLEBOARD MADE OF LIGNOCELLULOSE MATERIAL.

摘要

The invention relates to a method for manufacturing particleboard, having the same properties as particleboard made from wood particles or another lignocellulose material, which uses adhesives of any type and which is free of formaldehyde or other chemical or natural adhesives, the manufacture of said particleboard requiring the application of moderate levels of pressure and heat so as not to render the manufacturing cost of the product expensive. The method is primarily characterized in that it comprises a plurality of cycles of combined application of pressure and heat, reaching a temperature of between 90°C and 130°C and a pressure of between 25 and 35 kg/cm2, and the board is allowed to cool at the end of each cycle, one side of said board being moistened with water before application of the next cycle, the side which is moistened being alternated in each cycle.
