<p>A method for making fibre board, chip board etc. by binding a dinely divided raw material contng. some water and capillaries, permeable or semi-permeable membrane branes or other hollow spaces connected to the surface with a cold or hot setting binding agent. After binding the water in the hollow spaces is partly removed before pressing or moulding. The water is removed by diffusion or osmosis and the process carried out above the b.pt. to accelerate the drying or an exothermic material may be added.</p> |
