Process for the production of pulped cellulose material, in particular wood fibers, for the production of fiberboard and products produced

Abstract From the Canadian patent

A process is provided for the production of pulped cellulose material, preferably wood fibers in, particular up to a fiber length of 20 mm with a high, proportion of thermocurable resin the process being, suitable, in particular for the production of fiber-, containing moldings. In this process the, thermocurable resin, in aqueous, preferably alkaline solution, is added to a mixture of fiber particles and steam, and the steam is removed from the resincoated fiber particles in a drier. The steam is removed from the mixture of steam and fiber particles after addition of the resin, and the fiber particles are subsequently dried in a drying stage to a moisture content of less than 12% by weight …
