PROCESS FOR PREPARING A FIBROUS MATERIAL WITH HIGH CONTENT OF DRIED SUBSTANCE FOR MANUFACTURING FIBER PLATES FOLLOWING HUMID PROCESS WITH A CLOSED SYSTEM OF RECIRCULATING WATER

摘要

The process according to the invention comprises successively the following steps: deflection of the shanks in a 100-200 ° C saturated steam armor and proper pressure, suspension of the defibrated material, floating in the recycle water serving as a conveying liquid, foaming the mechanical separation of the recirculation water and its recirculation at the suspension passage, the final drying by vaporization of the water, characterized by the same chips containing more than 50% of the dry matter, are subjected to defibration with the simultaneous introduction of water recirculation in the defibrator in the spill of avoiding the heating of the fibrous material.
